COVID-19: Omicron BA.4 and BA.5 variants, not more severe or transmissible, so far


(United Nations News) As the coronavirus which causes COVID-19 continues to evolve, we cannot afford to ‘lose sight’ of the changes, the UN health agency said on Wednesday, warning that lower case numbers and deaths do not necessarily mean ‘lower risk’.

Tedros Adhanom Ghebreyesus reiterated that higher testing and sequencing rates are vital for scientists to track existing variants and to identify new ones as they emerge.
