- On January 31, the Ministry of Health announced that Omikron already accounts for over 59 percent. all infections in our country
- It turns out that Omikron can be even more contagious

The Omicron sub-variant is even more infectious
«We concluded that Omikron BA.2 is inherently more contagious than BA.1. It also has properties that reduce immunity to the disease, even in vaccinated people, ”reported in a collective publication by SSI, the University of Copenhagen, the Danish State Statistics Service and the Danish Technical University.
«If you have been in contact with Omikron BA.2 at home, there is 39% of chance of infection within seven days. With the BA.1 sub-option, the probability in the same circumstances is 29%. » – said Frederik Plesner, who conducted the study. These data indicate that BA.2 is more infectious than BA.1 by about 33%. – he noticed.

In addition, preliminary SSI analyzes showed that the risk of hospitalization did not change with both Omikron sub-variants.
The Danish study confirms the British Health Security Agency’s (UKHSA) preliminary analysis last week which found BA.2 appears to have a significantly higher spread than its predecessor, Reuters reports.
The first samples containing BA.2 were tested in the Philippines, but it is still unclear where the sub-variant first appeared. It has been detected so far, among others in the United States, Great Britain, Sweden and Norway. In Denmark, he is responsible for around 82 percent. all cases of SARS-CoV-2.
According to information from the World Health Organization (WHO), the Omikron variant is divided into three sub-options – BA.1, BA.2 and BA.3. (PAP)
