description: Background: Due to several sources of imprecision and inaccuracy of HCT and RBC Indices measurement in manual and automated methods difference in values may impact the clinical decision. Therefore, it would be essential to compare the three methods. Objective: To compare of Microhematocrit (Manual) Methods and Automated Hematology Analyzer (Sysmex XT-4000i) for determination of Hematocrit and Mean Cell Volume at Tikur Anbessa Specialized Hospital, Addis Ababa. Method: A hospital based comparative cross-sectional study was conducted in Tikur Anbessa Specialized Hospital (TASH) from January to March 2019 on 240 left over blood samples for Complete Blood Count (CBC) analysis. Hematocrit and MCV were determined Microhematocrit (Manual) using commercial and window clay sealant and Sysmex XT-4000i automated methods. The data obtained from the three methods were entered and analyzed using Statistical Package for SPSS version 23 software for windows. Standard deviation and mean were determined and Independent Student t-test was used to compare mean difference between the three methods on p-value of 0.05. Additionally, precision, correlation coefficient and Bland Altman plot were used to assess correlation and agreement between the tests. Also figures and tables were used for the description of the data. Result: The mean ±SD for three methods as follow as: HCT values were 40.9±14.91, 40.1±14.84 and 40.3±14.98 for automated, manual methods using commercial sealant and window clay respectively, MCV values were 85.7±9.18, 83.7±10.6 and 83.9±10.12 for automated, manual methods using commercial sealant and window clay respectively. There was no statistically significant difference between the automated and both manual methods (p>0.05) for the mean values of HCT. There was statistically significant difference in the mean values of MCV between automated and both manual methods (p<0.05), but no statistically significant difference between manual methods. HCT values of automated and manual methods using commercial sealant (positively correlated (r=0.984) and limit of agreement range (95%)) and window clay sealant (positively correlated (r=0.992) and limit of agreement range (96.25%)) and the manual methods each other had also positive correlation (r=0.988) and limit of agreement range of (95.75%). Conclusion: since there is good performance agreement for HCT, the results of automated method could be checked by both manual methods. Also the two manual methods interchangeably could be used for hematocrit determination in the case of inadequate sample.

description: We show how to transform a Dirac equation in curved spacetime into a Dirac equation in flat spacetime. In particular, we show that any solution of the free massless Dirac equation in a 1+1 dimensional flat spacetime can be transformed via a local phase transformation into a solution of the corresponding Dirac equation in a curved background, where the spacetime metric is encoded into the phase. In this way, the existing quantum simulators of the Dirac equation can naturally incorporate curved spacetimes. As a first example we use our technique to obtain solutions of the Dirac equation in a particular family of interesting spacetimes in 1+1 dimensions.

Publisher: name: The American Physical Society
Year: 2007
Subjects: subject: 530

description: Effective quantum-information processing requires coherent control of large numbers of qubits on a time scale that is short compared to the decoherence time of the system. It is therefore important to extrapolate and measure decoherence times for large quantum registers and to determine the effect of different couplings between system and environment on the decoherence rate. For this purpose, we have experimentally realized a system that allows one to generate model quantum registers with more than 100 qubits and measure the decay of the information in these states while adjusting the strength of the interaction between the quantum register and the environment. Our results indicate a power-law dependence of the decoherence rate on the number of qubits in the system, with an exponent of the order of 0.5. This behavior remains qualitatively unchanged when the coupling strength to the environment is reduced by about an order of magnitude.
Jacobi Type Continued Fractions for the Ordinary Generating Functions of Generalized Factorial Functions
Creators: name: Schmidt, Maxie D.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: The article studies a class of generalized factorial functions and symbolic product sequences through Jacobi type continued fractions (J-fractions) that formally enumerate the divergent ordinary generating functions of these sequences. The more general definitions of these J-fractions extend the known expansions of the continued fractions originally proved by Flajolet that generate the rising factorial function, or Pochhammer symbol, $(x)_n$, at any fixed non-zero indeterminate $x \in \mathbb{C}$. The rational convergents of these generalized J-fractions provide formal power series approximations to the ordinary generating functions that enumerate many specific classes of factorial-related integer product sequences. The article also provides applications to a number of specific identities, new integer congruence relations satisfied by generalized factorial-related product sequences and the $r$-order harmonic numbers, among several other notable motivating examples as immediate applications of the new results. In this sense, the article serves as a semi-comprehensive, detailed survey reference that introduces applications to many established and otherwise well-known combinatorial identities, new cases of generating functions for factorial-function-related product sequences, and other examples of the generalized integer-valued multifactorial, or $α$-factorial, function sequences. The convergent-based generating function techniques illustrated by the particular examples cited within the article are easily extended to enumerate the factorial-like product sequences arising in the context of many other specific applications.

description: We present here detailed derivations of mathematical expressions for the accuracy in the arrival direction of particles estimated using a set of stacked resistive plate chambers (RPCs). The expressions are validated against experimental results using data collected from the prototype detectors (without magnet) of the upcoming India-based Neutrino Observatory (INO). We also present a theoretical estimate of angular resolution of such a setup. In principle, these expressions can be used for any other detector with an architecture similar to that of RPCs.

description: Acetyl salicylic acid, deuterated at the methyl group, was investigated using 2H NMR in its supercooled and glassy states. Just above the glass transition temperature the molecular reorientations, studied using stimulated-echo spectroscopy, demonstrated a large degree of similarity with other glass formers. Deep in the glassy phase the NMR spectra look similar to those reported for the crystal and below 20 K they are indicating that rotational tunneling plays a role. Measurements of the spin-lattice relaxation times for temperatures below 150 K reveal a broad distribution of correlation times in the glass. The dominant energy barrier characterizing the slow-down of the methyl group motion is significantly lower than the well-defined barrier in the crystal.

description: Adiabatic quantum algorithms represent a promising approach to universal quantum computation. Whilst in a closed system these algorithms are limited by avoided level crossings, where the gap becomes exponentially small in the system size, their robustness in open systems remains unresolved. We study the dynamics in the proximity of such an avoided level crossing associated with the adiabatic quantum search algorithm in a quantum system that is coupled to a generic environment. At zero temperature, we find that the algorithm remains scalable provided the noise spectral density of the environment decays sufficiently fast at low frequencies. At finite temperature, however, scattering processes render the algorithm inefficient and no quantum speedup can be achieved. Owing to the generic nature of our model, we expect our results to be widely applicable to other adiabatic quantum algorithms.

Diagnostic Performance of Commercially Available Widal Test Kits for the Diagnosis of Typhoid Fever: the Case of One Public Hospital and a Health Center in Addis Ababa, Ethiopia
Creators: name: Temtem, Mastawesha
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: The causative agent of typhoid fever was first isolated in the late 19th century. The Widal agglutination test, utilizes a suspension of killed Salmonella Typhi as an antigen, to detect anti-H and anti-O agglutinins in serum from suspected Salmonella Typhi-infected patients. Information concerning the utility of Widal test in Ethiopia is limited and studies using multiple Widal test kits are even far less common. Objective: The objective of this study was to investigate the diagnostic performance of commercially available Widal test kits for the diagnosis of typhoid fever in Ethiopia. Methods: A cross-sectional study was conducted in two governmental health facilities in Addis Ababa, from October 2014 to February 2015 and a total of 192 typhoid fever suspected patients participated. Descriptive statistical analysis was conducted on the collected dataset for the purpose of data exploratory analysis. Different measures of agreements, between the Widal test kit brands as well as between slide agglutinations and tube titrations were carried out. Results: Results of the four commercially available Widal test kits under investigation showed plausibly strong test agreement with each other for slide agglutination methods (kappa statistics was k= 0.967 for anti-H and k= 0.786 for anti-O antibodies). Also in tube titration method, the four brands showed strong agreement (k= 0 .875 for anti-H and k= 0.850 for anti-O antibodies). In contrast, slide agglutination and tube titration agreement results of each brands showed a relatively lower agreement in anti-H (k <0.40) and a slightly better agreement in anti-O agglutinins, (k: 0.40–0.68). Among the 190 patient blood samples collected, 4 bacterial isolates were obtained in which, two of them were S. Typhi. Conclusion: In this study, the slide agglutination results of the four brands were generally good and comparable but the tube titration result agreements were lower than the agglutination agreement results. Also, a significance difference between slide agglutination and tube titration results of the four brands was found. The current study indicates that although the Widal test can be used as a good screening method treatment decisions should not be made solely based on results of slide agglutination.

description: Current connectivity diagrams of human brain image data are either overly complex or overly simplistic. In this work we introduce simple yet accurate interactive visual representations of multiple brain image structures and the connectivity among them. We map cortical surfaces extracted from human brain magnetic resonance imaging (MRI) data onto 2D surfaces that preserve shape (angle), extent (area), and spatial (neighborhood) information for 2D (circular disk) and 3D (spherical) mapping, split these surfaces into separate patches, and cluster functional and diffusion tractography MRI connections between pairs of these patches. The resulting visualizations are easier to compute on and more visually intuitive to interact with than the original data, and facilitate simultaneous exploration of multiple data sets, modalities, and statistical maps.

description: The holographic complexity and fidelity susceptibility have been defined as new quantities dual to different volumes in AdS. In this paper, we will use these new proposals to calculate both of these quantities for a variety of interesting deformations of AdS. We obtain the holographic complexity and fidelity susceptibility for an AdS black hole, Janus solution and a solution with cylindrically symmetry, an inhomogeneous background and a hyperscaling violating background. It is observed that the holographic complexity depends on the size of the subsystem for all these solutions and the fidelity susceptibility does not have any such dependence.

description: Alternative derivatives of the original yield-goal based recommendations have been employed by researchers, outreach personnel, and private-sector crop management consultants to direct farmers. Current research indicates, however, that the original yield-goal-based method used scant data, questionable data omissions, and flawed statistical analysis. Maximum Return to Nitrogen (MRTN) recommendation is the first publicly available nitrogen recommendation tool to consider economic outcome when recommending nitrogen application rate. However, MRTN adoption is low; farmers may still be following retailer recommendations or prior experience, in part because the nitrogen application rate suggested by the MRTN system is relatively low. This study aims to determine the efficiency of the MRTN recommendations in directing nitrogen application rates in the corn belt. Between 2016 and 2021, forty-two on-farm precision experiments were conducted in Illinois and Ohio to determine the ex-post economically optimal nitrogen rate (EONR), which are used here to evaluate MRTN rates. MRTN rates are compared to the current rates of farmers to determine which achieves relatively high profit margins. Findings suggest that MRTN recommendations can be excessively high or inadequately low across fields in the same region and during the same year. Additionally, grower chosen rates performed better than MRTN on some fields in some regions. Thus, adopting the MRTN recommendation appears riskier than developers claimed.

description: Background: Type2 diabetes mellitus and its complication are becoming more prevalent in Ethiopia. It is estimated that 2-3 % of the population is living with diabetic. No Study is available in correlation of Apolipoprotein and lipid profile that is relevant in diagnosis and monitoring of diabetic dyslipidaemia in our local set up. Therefore the current study assessed the correlation of Apolipoprotein with lipid profile. Objective: Assessment of Dyslipidaemia using lipidprofile, lipid ratios and Apolipoprotein value in type 2 diabetic patients who are apparently healthy attending diabetic clinic of the Tikur Anbessa Specialized Teaching Hospital, Addis Ababa. Method: A Crossectional study was done during the study period from 15/10/2014 to 24/10/2016.Demographic variables were measured and Dyslipidaemia was assessed from overnight fasting serum sample by measuring Apolipoprotiens and lipid profile. Degree of association and/or correlation between Apolipoprotein and classical lipid profile was evaluated using Spearman, Pearson correlation, independent sample t test , Man Whitney test and Chi square appropriately. SPSS version 20 software was used and histogram, Box Plot and Scatter plot was used to display results. Result: A total of 70 type 2 Diabetic patients were participated in the study. Median age of the participants was 47(31-64). Dyslipidemia Observed in participants were high TC, low HDL, high LDL , high TG, low Apo A1, high Apo B100 ,high non HDL and high lipid ratios. Apo B 100 and Apo A1 are positively associated with LDL and HDL respectively. In addition lipid ratios had significant positive association with atherogenic lipid parameters and negative association with anti-atherogenic lipid parameters. Conclusion: Apolipoprotein A1 and B100 are associated with classical lipid profiles that help in diagnosis of dyslipidaemia in type 2 Diabetic patients
Major Challenges of Medical Laboratories for ISO 15189 Accreditation in Selected Government Hospitals of Addis Ababa, Debrebrhan, and Bishoftu, Ethiopia
Creators: name: Girma, Mekonnen
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: Numerous global initiatives in Africa have focused on clinical laboratory harmonization and standardization, and accreditation. Though accreditation has many advantages and advocated largely, it is still challenging for the laboratories to fulfill all requirements and the criteria of accrediting bodies. So identifying the different challenges faced by the laboratories during the process of accreditation is important for proper planning and action to resolve those challenges. Objective: To assess the major challenges of Medical Laboratories for ISO 15189 accreditation in selected government hospitals of Addis Ababa, Debrebrhan, and Bishoftu, Ethiopia. Method: Cross sectional study design using qualitative and quantitative data collection approach was used from March to May 2017. The data for this study was gathered using structured questionnaire and in-depth interview. Stratified-proportional sampling technique was used. Data was entered, cleaned using EPI-Data 3.1 and exported to SPSS version 20 software for further processing and analysis. Simple descriptive statistics like percentages and frequency was used. The qualitative data from in-depth interview were categorized and discussed. Result: In this research 175 questionnaire respondents and 24 key informants from 12 hospitals were included to identify the major challenges facing medical laboratory's accreditation process. All respondents had awareness about the accreditation process but only 79% of them have involved in the process in one or more ways. More than half of the respondents (51%) had training experience related to either laboratory LQMS or ISO accreditation. High turnover of trained and experienced laboratory professionals for better job opportunity and education was reported to mainly affect the accreditation process. Routine work load, poor equipment quality, shortage and quality of laboratory supplies, inconsistent mentorship and training, strict assessment process and low attention and commitment from top management were among the major challenges identified. Conclusion: Even though there exists an effort to fulfil accreditation requirements, achieving and maintaining accreditation was still challenging for many facilities due to; trained staff turnover, training and mentorship inadequacy, low staff satisfaction, low quality and quantity of equipments, low top management support, and poor quality laboratory facility. This study highlights the need for stronger engagement, commitment and advocacy with all stakeholders to harmonize and lead accreditation program effectively.

description: We compute the parametrized post-Newtonian parameter $γ$ in the case of a static point source for multiscalar-tensor gravity with completely general nonderivative couplings and potential in the Jordan frame. Similarly to the single massive field case $γ$ depends exponentially on the distance from the source and is determined by the length of a vector of non-minimal coupling in the space of scalar fields and its orientation relative to the mass eigenvectors. Using data from the Cassini tracking experiment, we estimate bounds on a general theory with two scalar fields. Our formalism can be utilized for a wide range of models, which we illustrate by applying it to nonminimally coupled Higgs SU(2) doublet, general hybrid metric-Palatini gravity, linear ($\Box^{-1}$) and quadratic ($\Box^{-2}$) nonlocal gravity.

description: We study particle production at the preheating era in inflation models with nonminimal coupling $ξϕ^2R$ and quartic potential $λϕ^4/4$ for several cases: real scalar inflaton, complex scalar inflaton and Abelian Higgs inflaton. We point out that the preheating proceeds much more violently than previously thought. If the inflaton is a complex scalar, the phase degree of freedom is violently produced at the first stage of preheating. If the inflaton is a Higgs field, the longitudinal gauge boson production is similarly violent. This is caused by a spike-like feature in the time dependence of the inflaton field, which may be understood as a consequence of the short time scale during which the effective potential or kinetic term changes suddenly. The produced particles typically have very high momenta $k \lesssim \sqrtλM_\text{P}$. The production might be so strong that almost all the energy of the inflaton is carried away within one oscillation for $ξ^2λ\gtrsim {\mathcal O}(100)$. This may partly change the conventional understandings of the (p)reheating after inflation with the nonminimal coupling to gravity such as Higgs inflation. We also discuss the possibility of unitarity violation at the preheating stage.

Method: The present study was a laboratory based cross-sectional study conducted at Arsho Advanced Medical laboratory, Addis Ababa, Ethiopia from January to April 2019; A total of 422 blood samples was collected and inoculated on to primary isolation culture following standards protocols. Species identification and antimicrobial susceptibility testing of bacteria were determined by automated Vitek2 compact system (bio Merieux, France) using AST, GN72 card for gram negatives and AST,GP71 card for gram positive bacteria. Result :Out of a total of 422 samples processed, bacterial pathogens were isolated from 89(21.1%) samples. Among the isolates, 52 were Gram- positive and 37 were Gram negative bacteria.Coagulasenegative staphylococci and Klebsiellaspp were the dominant isolates. Penicillin (92.3%) was the least effective antibiotic against Gram-positive bacteria while cephalotin (91.1%) and cephazolin (89.2%) were the least effective antibiotic against Gramnegative bacteria. Linzolid and Tigcyclne(98.1%) were the most effective antibiotic against Gram positive and piperacillin(86.1%) were the most effective antibiotic against Gram-negative bacteria, Out of 52 isolate of Gram-positive bacteria 30(57.7%) were MDR and out of 37 isolates of gram negative bacteria 20(54%) were MDR. Conclusion:The magnitude of blood stream bacterial infection and the prevalence rate of multidrug resistant bacterial strains causing blood stream infections were high. These findings warranted the need for continuous investigations bacterial blood stream infection.

Creators: name: Zebene, Wegayehu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Background: Urinary tract infection is commonly encountered health problem among pregnant women. Untreated urinary tract infection may result in fetal complications like preterm birth, low birth weight, intra uterine growth retardation, and intrauterine fetal death. The problem of urinary tract infection is further compounded by the development of drug resistance. Determining drug susceptibility pattern of bacteria from urinary tract helps to identify effective drugs and minimize further adverse perinatal outcomes. Objective: The objective of this study was to describe the magnitude and drug resistance profile of pregnant women and related fetal outcomes during their third trimester period at Gerji, Felege Meles health centers and Tikur Anbesa Specialized Hospital, Addis Ababa, Ethiopia. Methods: A cross-sectional study was conducted from March to June 2019. Socio-demographic data of the study participants were collected by administering structured questionnaire after obtaining full consent of the participants. Clean catch mid-stream urine was collected from the study participants and the samples were transported to the Ethiopian Public Health Institute laboratory with screw-capped container. Blood and MacConkey agar was used to culture the urine sample. Bacterial colonies were isolated and identified by their biochemical properties. Antibacterial susceptibility test was done on Muller-Hinton agar using different antibiotic discs and confirmed by VITEK2 Compact machine. At the time of delivery, infant's birth weight and gestational age was recorded on the log book as part of the daily work. Fetal outcome data required for the study were recorded from the log book and entered to EPI data management software then transferred to SPSS for analysis. Result: Out of 424 urine samples processed, 63 (14.9%) yielded significant bacteriuria. Out of sixty three samples, fifty nine (93.7%) cases of UTIs were recorded among age group of 15-34years. Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus were the three dominant bacterial isolates. Most of the gram negative bacterial isolates were resistant to ampicillin and ceftazidime (43.2% each) while gram positive were resistant for tetracycline (36.8%). The result of this study showed that UTI had statistically significant association with the occurrence of Intrauterine fetal death (IUFD) and prerupture of membrane (PROM) (P<.05). ix Conclusion: Adverse fetal outcomes are significantly linked with the presence of UTI during pregnancy. The condition can be managed if early diagnosis and treatments are made for the mother. The study highlights that, UTI related adverse fetal outcomes reaches to the level that requires early interventions.

description: A link between microcomputer and mainframe can be useful in several ways, even when, as is usually the case, the link is only a normal terminal line. One interesting example is the ‘Integrated application’, which divides a task between microcomputer and mainframe and can offer several benefits; in particular, reducing load on the mainframe and permitting a more advanced user interface than possible on a conventional terminal. Because integrated applications consist of two co-operating programs, they are much more difficult to construct than a single program. It would be much easier to implement integrated applications concerned with the display and/or modification of data in mainframe files if the microcomputer could confine its dealings with the mainframe to a suitable file server. However, file servers do not appear practical for use over slow (compared to disc access speed) terminal lines. It was proposed to alleviate the problems caused by the slow link with extended file operations, which would allow time-consuming file operations such as searching or copying between files to be done in the file server. It was discovered after attempting such a system that extended file operations are not, by themselves, sufficient; but, allied to a record-based file model and asynchronous operations (i.e. file operations that do not suspend the user program until they complete), useful results could be obtained. This thesis describes FLAP, a file server for use over terminal lines which incorporates these ideas, and MMMS, an inter-application transport protocol used by FLAP for communication between the microcomputer file interface and the mainframe server. Two simple FLAP applications are presented, a customer records maintenance program and a screen editor. Details are given of their construction and response time in use at various line speeds.

description: We revisit the computation of instanton effects to various correlation functions in ${\cal N}=4$ SYM and clarify a controversy existing in the literature regarding their consistency with the OPE and conformal symmetry. To check these properties, we examine the conformal partial wave decomposition of four-point correlators involving combinations of half-BPS and Konishi operators and isolate the contribution from the conformal primary scalar operators of twist four. We demonstrate that the leading instanton correction to this contribution is indeed consistent with conformal symmetry and compute the corresponding corrections to the OPE coefficients and the scaling dimensions of such twist-four operators. Our analysis justifies the regularization procedure used to compute ultraviolet divergent instanton contribution to correlation functions involving unprotected operators.

Tuning nonradiative lifetimes via molecular aggregation

description: We show that molecular aggregation can strongly influence the nonradiative decay (NRD) lifetime of an electronic excitation. As a demonstrative example, we consider a transition-dipole-dipole-interacting dimer whose monomers have harmonic potential energy surfaces (PESs). Depending on the position of the NRD channel ($q_{\rm nr}$), we find that the NRD lifetime ($τ_{\rm nr}^{\rm dim}$) can exhibit a completely different dependence on the intermolecular-interaction strength. We observe that (i) for $q_{\rm nr}$ near the Franck-Condon region, $τ_{\rm nr}^{\rm dim}$ increases with the interaction strength; (ii) for $q_{\rm nr}$ near the minimum of the monomer excited PES, the intermolecular interaction has little influence on $τ_{\rm nr}^{\rm dim}$; (iii) for $q_{\rm nr}$ near the classical turning point of the monomer nuclear dynamics, on the other side of the minimum, $τ_{\rm nr}^{\rm dim}$ decreases with the interaction strength. Our findings suggest design principles for molecular systems where a specific fluorescence quantum yield is desired.

description: Background: Acute respiratory illnesses (ARI) are among the major public health problems both in developed and developing countries. No any previous studies describing about the types and magnitude of viral etiologies responsible for acute respiratory infections in both severe acute respiratory illness (SARI) and influenza like illness (ILI) in Ethiopia except influenza viruses. Objective: To assess common respiratory viruses among acute respiratory illness cases in selected health facilities in Ethiopia. Method: Laboratory test by RT-PCR was conducted at National Influenza Reference Laboratory of Ethiopian Public Health Institute (EPHI) from 01, July, 2017 to 31, October, 2017 combination of retrospective and prospective study designs. Throat/throat and nasopharyngeal swab samples collected from 01, January, 2015 to 31, December 2016 from influenza sentinel surveillance sites were selected by systematic random sampling technique for detection of Parainfluenza viruses1-4 (PIV1-4), Human coronaviruses (HCoV), Human metapneumoviruses A/B (HMPV A/B); Rhinovirus (RV); Respiratory syncytial viruses A/B (RSV A/B); Human adenovirus (HAdV), Enterovirus(EV), Human parechovirus (HPeV),Human bocavirus (HBoV) and Influenza virus C (INF C). Descriptive statistics was done using SPSS version 20. Results: A total of 422 samples which consisted of 202 (47.9%) male were tested. Children under age of five years accounted for 47.6% (201) of the tested samples. Equal number of samples from outpatients and hospitalized cases were tested. Among the tested samples 55.5% ( 234/422) were positive for at least one respiratory virus and most frequently detected among children under five years of age (p=0.023). Respiratory viruses were co-detected in 18.2% (77) of the samples and 79.2% (61/77) were from SARI cases (p=0.007). The most frequently detected respiratory viruses were RV (18.7%), RSV A/B, (12.8%), HAdV (11.4%) and PIV1-4 (7.3%). HCoV(6.2%),EV(6.2%), HPeV(5.7%, HMPV A/B(4.5%), HBoV (3.8%). INF C (0.2%) were also detected Conclusion and recommendation: The study detected the circulation of wide range of respiratory viruses among samples from ILI and SARI cases especially among under five children. Large scale study has to be done to better understand the seasonal variation, spectrum of illness and severity of ARI due to the different respiratory viruses.
