[Q]: medRxiv preprint Interpretation Parameters that successfully reproduce the observed number of cases indicate that both R 0 and the prevalence of the virus might be underestimated. This is in concordance with the newest research on undocumented COVID-19 cases. Consequently, the actual mortality rate is putatively lower than estimated. Confirmation of the pandemic characteristic by further refinement of the model and screening tests is crucial for developing an effective strategy for the global epidemiological crisis. 1 Balcan D, Gonçalves B, Hu H, Ramasco JJ, Colizza V, Vespignani A.

[Q]: Limited data exist on how SARS-CoV-2 enters and spreads in the general population. We used two strategies for SARS-CoV-2 testing: targeted testing of high-risk individuals (n=4,551) and a population screening (n=5,502). We sequenced SARS-CoV-2 from 340 individuals. RESULTS March 22 2020, 528 had tested positive for SARS-CoV-2 in the targeted testing (11.6%) and 50 in the population screening (0.9%); approximately 0.2% of the Icelandic population. Large fractions of positives had travelled outside Iceland (38.4% and 34.0%). Fewer under 10 years old were positive than those older: 2.8% vs. 12.3% for targeted testing (P=1.6e-9) and 0.0% vs. 1.0% for population screening (P=0.031). Fewer females were positive in the targeted testing than males (9.5% vs. 14.6%, P=6.8e-9). SARS-CoV-2 came from eight clades, seven A clades and one B clade. The clade composition differed between the testing groups and changed with time. In the early targeted testing, 65.0% of clades were A2a1 and A2a2 derived from Italian and Austrian skiing areas, but in the later targeted testing went down to 30.6% and were overtaken by A1a and A2a, the most common clades in the population screening. SARS-CoV-2 has spread widely in Iceland outside of the high-risk groups. Several strains cause these infections and their relative contribution changed rapidly.

[Q]: Porcine reproductive and respiratory syndrome (PRRS) is an economically important disease to pork producers worldwide. Commercially, both live and killed PRRSV vaccines are available to control PRRS, but they are not always successful. Based on the results of mucosal immunization studies in other viral models, a good mucosal vaccine may be an effective way to elicit protective immunity to control PRRS outbreaks. In the present study, mucosal adjuvanticity of Mycobacterium tuberculosis whole cell lysate (Mtb WCL) was evaluated in pigs administered a modified live PRRS virus vaccine (PRRS-MLV) intranasally. A Mtb WCL mediated increase in the frequency of NK cells, CD8 + and CD4 + T cells, and ␥␦ T cells in pig lungs were detected. Importantly, an increased and early generation of PRRSV specific neutralizing antibodies were detected in PRRS-MLV+ Mtb WCL compared to pigs inoculated with vaccine alone. In addition, there was an increased secretion of Th1 cytokines (IFN␥ and IL-12) that correlated with a reciprocal reduction in the production of immunosuppressive cytokines (IL-10 and TGF␤) as well as T-regulatory cells in pigs vaccinated with PRRS-MLV+ Mtb WCL. Further, a complete rescue in arginase levels in the lungs mediated through Mtb WCL was observed in pigs inoculated with PRRS-MLV. In conclusion, Mtb WCL may be a potent mucosal adjuvant for PRRS-MLV in order to potentiate the anti-PRRSV specific immune responses to control PRRS effectively.
