An overview of variants and mutations to give us an update on the SARS-CoV-2 VOC* and VOI** as classified by WHO.
How often does SARS-CoV-2 mutate? As any virus, it is likely to change or mutate to adapt to the environmental pressure as it infects people. There are several variants that are now spreading, some proving to be more contagious as well as with higher mortality than the original virus.
Is COVID-19 seasonal like the flu? While it had been hoped initially that higher temperatures and humidity levels might help slow down the spread of the coronavirus, the seasonality of the epidemy is not that clear. Experts announced the fourth wave and advise caution: the public health efforts have more influence than the weather.
How long will the Coronavirus last? There’s no way of telling how long will the pandemic last. There are many factors, including the public’s efforts to slow the spread, researchers’ work to learn more about the virus, their search for the treatment, and the deployment of vaccination programs.
