The World Health Organization was told last week that, and what data these cases have reached, there are fewer cases on the ground because global surveillance activities, including analysis and testing, have dropped dramatically.

Dr. Maria explained that there are many subspecies of the Omicron variant and they are classified as Omicron and all of them are listed as types of concern, explaining that the WHO specifically monitors the BA.4, BA.5 and BA.2.75 types.

All subspecies of the omicron variant are classified as variants of concern. Each substrain of the omicron variant and each iteration of SARS-CoV-2 is of concern to the World Health Organization because the virus is spreading more aggressively globally, Dr. Maria said.

About Omicron BA.4 and BA.5 substrains Dr. Maria said this is the most spreadable variant we’ve seen so far, and that BA.5 has a distinct growth advantage over other substrains discovered.

Same intensity and intensity

Lack of access to vaccines

Dr. Maria Van Gerkov explained that the virus is constantly evolving and there is uncertainty about how the virus will change over time, and there are some clues about it, but we don’t know for sure, and the risk it poses. Even more so as the SARS-CoV-2 virus continues to claim more lives.

As for public opinion, people really want to overcome this epidemic, but the risk is still there, says Dr. Maria, explaining that a large part of the reason for the continued risk is the lack of access to vaccines around the world. , as there are billions of people around the world who have not received the full course of vaccination.
