Preliminary data indicate an increased risk of re-infection of those who have recovered from COVID when exposed to a new strain of "omicron". This was stated by the World Health Organization (WHO).
At the same time, the organization emphasized that so far there is not enough data confirming the information that the new strain of coronavirus “omicron” is more dangerous than “delta”. “It is not yet clear whether omicron is more transmissible—for example, more easily transmitted from person to person—compared to other variants, including the delta variant,” the report said.
The WHO notes that the number of people with a positive test result for coronavirus in South Africa, where an outbreak of a new strain was recorded, has increased, but epidemiological studies are ongoing to understand whether this is due to "omicron" or whether other factors influenced it.

According to WHO experts, it also remains unclear whether the omicron strain leads to a more severe course of the disease compared to other mutations of the infection, including the "delta". “According to preliminary data, there is an increase in the number of hospitalizations in South Africa, but this may be due to an increase in the total number of infected people, and not infection with the Omicron strain,” the organization said.
