The World Health Organization (WHO) says it is investigating whether two new subtypes of omega-3 coronavirus, BA.4 and BA.5, are highly contagious or dangerous.
The World Health Organization is also monitoring mutations in the BA.1 ohmicron, BA4 and BA.5, as well as variants BA.1, BA.2, BA.1.1 and BA.3, which are already widely used worldwide.
The World Health Organization (WHO) says it is beginning to monitor these variants as more variants and their impact on the immune response need to be further studied.
Currently the BA.2 virus is highly contagious worldwide, but studies show that this type is unlikely to cause serious harm. Furthermore, BA.4 and BA.5 viruses are endemic to only a few people worldwide. The BA4 virus was detected in South Africa, Denmark, Botswana, Scotland and the UK between January 10 and March 30, according to the UK Healthcare Agency. BA.5 virus has been found in South Africa and Botswana
