Host genetic loci LZTFL1 and CCL2 associated with SARS-CoV-2 infection and severity of COVID-19
High variability in the clinical presentation of COVID-19 has consistently been described (World Health Organization, 2021). Most patients experience asymptomatic infection or mild disease only, whereas 14% suffer from severe and 5% from critical disease (Hu et al., 2021). The most common symptoms include fever, dry cough, and fatigue; ageusia, anosmia, and gastrointestinal symptoms are also observed (Hu et al., 2021; Velavan and Meyer, 2020a). Severe COVID-19 is characterized by respiratory failure, requiring mechanical ventilation or high-flow oxygen (Table 1, WHO Working Group on the Clinical Characterisation and Management of COVID-19 infection, 2020).How to (ab)use a COVID-19 antigen rapid test with soft drinks?
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.A call to caution when hydroxychloroquine is given to elderly patients with COVID-19
The coronavirus disease (COVID-19) pandemic initiated an urgent search for safe, effective treatments. Repurposing approved drugs for the treatment of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection can save considerable effort, time and costs (Krishna et al., 2020). These drugs must be suitable for use in elderly patients and those with underlying health conditions as these groups are at particular risk of severe disease and complications.COVID-19 and syndemic challenges in ‘Battling the Big Three’: HIV, TB and malaria
All countries where malaria is endemic have reported COVID-19 cases. The WHO African Region has experienced >1.5 million cases of COVID-19 (WHO, 2020a) and bears 90% of the global malaria burden. Significant efforts have led to a substantial reduction in malaria deaths in the last decade (WHO, 2019a) and enduring sustainability of malaria interventions and control programs is essential. As signs and symptoms of COVID-19 and malaria partly overlap, diagnostic guidance is inevitable in malaria-endemic settings.Genomic surveillance of SARS-CoV-2 in the Republic of Congo
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).
