Coronavirus (COVID-19) Collection
- SARS-CoV-2 variants of concern (VOC) appear to spread more easily. Other emerging variants are also gaining attention, either known as a "variants of interest" (VOI) or "variants under investigation" (VUI), which increase transmission, warranting further studies. Since the onset of the COVID-19 pandemic, the SARS-CoV-2 genomes have accumulated genetic diversity, leading to increased transmission with altered viral properties (Kraemer et al. 2021).
- With reasonably good specificity and sensitivity, the speed and convenience of COVID-19 antigen tests have led to self-testing in schools, offices, and universities in the European Union (EU). Although self-testing can be beneficial and increase the accessibility to testing, there are potential ways to confound a positive COVID-19 lateral flow test. We observed that all soft drinks, energy drinks, alcoholic beverages (vodka, whiskey, and brandy), commercially bottled mineral water, and carbonated mineral water caused the appearance of a red test line.
- With the first cases reported on March 14, 2020 (Ntoumi and Velavan, 2020), the Republic of Congo reported a total of 7794 cases with 117 deaths as of January 25, 2021, with transmission driven by the community (WHO, 2021).
