WHO warns Covid-19 virus continues to develop its new variants

WHO warns Covid-19 virus continues to develop its new variants. 

The World Health Organization (WHO) has issued a warning that the Covid-19 virus is still evolving and that a new variety will appear in the coming days. 

However, according to the Covid-19 Weekly Epidemiological Update provided by WHO on Tuesday, the Omicron type remains a major strain circulating globally.

The World Health Organization said it is still monitoring several descendent lineages’ of the Omicron version of the coronavirus, including two new sublineages with additional mutations linked to possible disease “characteristics of immune evasion.

According to the WHO, many descendent lineages under the Omicron Variant of Concern are still being monitored, including BA.1, BA.2, BA.3, and now BA.4 and BA.5. It also includes circulating recombinant versions of BA.1/BA.2, such as XE.

It also stated that it is collaborating with scientists to understand better the peculiarities of these lineages and their implications for public health. “Wherever practicable, the WHO advises governments to maintain surveillance and prompt data sharing on publicly accessible databases.”

According to the World Health Organization, the SARS-CoV-2 virus is still evolving. New variations, including recombinants, are likely to occur with such widespread transmission. “This was to be expected.”

WHO is tracking the two new sublineages (BA.4 and BA.5) in the Omicron variation. 

Additional mutations in these variations need to be investigated further to understand their impact on immunological escape potential. 

Unfortunately, only a few dozen of these variations’ sequences have been published from a few countries.

WHO collaborates with scientists to better understand their present prevalence and potential consequences. 

According to the WHO, the rapid and nearly synchronized increase in the global incidence of Covid-19 cases reported through January 2022 has been linked to Omicron’s immune escape capabilities.

A delayed increase in cases of occurrences in the Western Pacific Region and a resurgence in the number of new cases reported in the European Region drove a further rise at the beginning of March.

“This trend was likely due to a combination of factors, including the predominance of the Omicron Pango lineages BA.1, then BA.2, which have a transmission advantage over other Omicron lineages; relaxation of public health and social measures (PHSM); and waning of humoral immunity following vaccination and/or prior infection,” the report stated.

“The discovery of Delta-Omicron and Omicron descendent lineage recombinants necessitates continued cautious observation.”

According to the WHO update, the number of new Covid-19 cases and deaths worldwide decreased for the third week in a row during the week of April 4 through 10, with over 7 million cases and over 22,000 deaths reported, down by 24% and 18%, respectively, from the previous week.

The number of new weekly cases and deaths in all regions showed a downward trend. As of April 10, over 496 million confirmed cases and nearly 6 million deaths worldwide.
