Title: Improving Diagnosis of Tuberculosis in HIV Infected Children in Asia (Cambodia, Vietnam) and Africa (Burkina Faso, Cameroon) ANRS 12229 PAANTHER 01 (Pediatric Asian African Network for Tuberculosis and HIV Research)
Brief Summary: Childhood tuberculosis (TB) accounts for 11% of the total 9 million annual TB cases and the difficulty of its diagnosis is increased in case of HIV infection in children.

The aim of this study is to improve TB diagnosis in HIV-infected children by developing a new diagnostic algorithm incorporating new tools available such as:

* interferon gamma release assays (IGRAs), as alternative to the tuberculin skin test
* alternative specimen collection methods such as string test (or Enterotest (R)), nasopharyngeal aspirates and stools samples, as alternatives to gastric aspirate
* the Xpert MTB/RIF assay


Options:
A: Inclusion Criteria:

* Men and women of ≥18 years of age
* Presence of cough, fever, night sweats or weight loss
* Ability and willingness to give written informed consent
* Documentation of positive HIV status (test conducted at GHESKIO)
* Acceptance of HIV diagnosis, defined as affirmative responses to two questions: "I believe that HIV and AIDS exist" and "I believe that the results of my HIV test show that I am infected".

Exclusion Criteria:

* Any use of ART in the past
* Treatment for TB in the year prior to screening visit
* Pregnancy or breastfeeding at the screening visit
* Active drug, alcohol use, or mental condition that would interfere with the ability to adhere to study requirements, in the opinion of the study physician
* Score of \<3 for any of the 7 questions on the ART readiness survey
* Planning to transfer care to another clinic during the study period

* Severe illness, classified as one of the WHO "danger signs" of temperature \>39 degrees Celsius, pulse \>120 beats/minutes, respiratory rate \>30, or inability to walk unaided.
B: Inclusion Criteria:

* The patient is willing to provide specimens (urine, blood, stool, respiratory tract specimens and swabs)
* The patient is clinically suspected of having TB (Two WHO TB symptoms for HIV negative patients and one WHO TB symptom if HIV positive)

Exclusion Criteria:

* The patient is under the age of 18 years old
* The patient declines consent
* The patient has too few clinical symptoms for TB
C: Inclusion Criteria:

* HIV-positive
* 18 years and above
* Able to give informed consent
* Admitted at the wards attached to the research site ART/HIV-clinic
* Eligible for LF-LAM testing (defined by WHO in the LF-LAM policy update 2019): CD4-cell-count ≤200 cells/μL (the last measured CD4-cell-count); or a WHO clinical stage 3 or 4 event at presentation for care; or seriously ill defined by WHO (respiratory rate \> 30/min, temperature \> 39°C, heart rate \> 120/min or unable to walk unaided); or a positive WHO TB symptom screening including one of the following symptoms: current cough, fever, weight loss, or night sweats

Exclusion Criteria:

* Anti-tuberculous treatment including preventive treatment with Isoniazide within the last 60 days
* Earlier participation in the same study
D: Inclusion Criteria:
