The BA.2 subspecies omichron has not been found to cause any more severe illness than the original strain.
Like other strains of COVID in the Omikron family Covid-19 vaccine approved for use at present decreased effectiveness against this subspecies of omikron. And virus protection levels have declined over time, however, the British Health Service said that virus protection levels and prevent severe illness and death from various strains of COVID-19 can be restored by receiving immunization or booster
global overview
The rise of Omicron BA.2 cases was seen in both the soaring number of infections in China. as in many European countries like Germany and England
Researchers have referred to the virus as Since BA.2 contains the missing genes from the BA.1 precursor virus, PCR detection is more difficult than ever. moreover Omikron subspecies BA.2 and newcomer BA.3, which have already begun to find some infections today. It can only be detected through genomic sequencing.
have been infected and can be re-infected
One worrying factor about Invisible Omikron BA.2 is the re-infection among those who have been infected with the original BA.1 omikron, particularly among countries facing repeated outbreaks. But according to data from England and Denmark, Omicron coronavirus can be re-infected to people who have been infected with other coronavirus strains, such as the delta mutant coronavirus. While a small number of people who have been infected with the original omicron have re-infected the BA.2 subspecies of coronavirus.

Scientists view that the epidemic of Covid BA.2 around the world around This could come from the simultaneous easing of coronavirus control measures in many parts of the world, said Andrew Pecosz, a virologist at the Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland. that covid omicron BA.2 may spread as people stop wearing masks now
Another US expert, Eric Topol, director of the Scripps Research Translational Institute in California. It’s too early to say that the United States will face a significant wave of outbreaks of the sub-species of Covidron BA.2
Mark Woolhouse, an epidemiologist at the University of Edinburgh, said the new outbreak was a major public health problem. And it’s still an ongoing situation.
Whatever the reason for the BA.2 subspecies of the coronavirus pandemic, the cause. But scientists are of the opinion that This is a reminder that viruses will still be dangerous. especially among those who have not been vaccinated against COVID-19. People who have not received the full dose of the coronavirus vaccine including with vulnerable populations
