The correct evaluation of the reproductive number R for COVID-19 is central in the quantification of the potential scope of the pandemic and the selection of an appropriate course of action. In most models, R is modeled as a constant - effectively
Variability in treatment effects is common in intervention studies using cluster randomized controlled trial (C-RCT) designs. Such variability is often examined in multilevel modeling (MLM) to understand how treatment effects (TRT) differ based on
BACKGROUND: Uptake of the COVID-19 bivalent booster vaccine (targeting the original SARS-CoV-2 strain and subvariants BA.4 and BA.5 of the Omicron variant) among eligible residents of New York City (NYC) has been modest and declining. Assessing the
On 21 March 2023 the Tanzania's Ministry of Health reported the first Marburg virus disease (MVD) outbreak in Bukoba District reporting a total of eight cases and five fatalities including one health care worker with a case fatality ratio of 62.5%
CONCLUSIONS: In this study, the level of agreement for COVID-19 results between the mHealth-supported syndromic assessment and the actual laboratory-confirmed result was reasonable at 89%. mHealth-supported syndromic assessment of COVID-19 is a
CONCLUSION: Hospitalized infants with COVID-19 were depleted in some gut bacteria, such as bifidobacteria, in particular Bifidobacterium breve, which is crucial for the proper establishment of a functional intestinal microbiota, and important for
We use viral kinetic models fitted to viral load data from in vitro studies to explain why the SARS-CoV-2 Omicron variant replicates faster than the Delta variant in nasal cells, but slower than Delta in lung cells, which could explain Omicron's
The final months of 2019 saw the emergence of a new pandemic termed "COVID-19". Since then, this infection and its complications have been the priority of healthcare providers, with many symptoms attributed to its early and late presentations. Thus
