WHO warns COVID-19 is still changing amid increasing cases
WHO has warned that the Covid-19 virus has been changing since it was first reported, and it continues to change. So far, four variants of concern have emerged and there will be more as long as the virus continues to spread. The rise is also driven by increased social mixing and mobility, the inconsistent use of public health and social measures and inequitable vaccine use.
