SARS-CoV-2 is an RNA virus. However, the enzyme responsible for replication of the virus genome to create new viral particles, polymerase, commits many errors. These mutations may persist if they endow the virus with an advantage. When a certain number of mutations accumulate, the virus becomes a variant, meaning a virus which is very close […]

Mask distribution with individual advice: the example of Bangladesh

The United Nations did not recommend mask wearing for the overall population before June 2020. There were insufficient clinical trials in real-world conditions to prove their usefulness, and reservations were expressed over counter-productive behaviour that a “false feeling of security” might provoke. But today, in poorer countries that lack access to anti-COVID-19 vaccines, this type […]

Large-scale studies over-estimate vaccination coverage

In the fight against COVID-19, public health officials rely on surveillance data that is either collected physically (during a visit to the doctor, for example) or through on-line surveys. Small-scale studies carry the risk of targeting an unrepresentative sample of the population, while large-scale surveillance is potentially more useful, since it enables, through specific statistical […]

The emergence of Variants of Concern (VOCs) with increased transmissibility and capable of escaping immunity has called into question the efficacy of current vaccines. Several studies have shown that these variants’ new capacities involve mutations in the spike protein that controls entry of the virus into cells. The Omicron variant, recently identified in South Africa, […]
