A new coronavirus variant, NB.1.8.1, is spreading globally, with cases detected in Asia, India, the USA, and Russia. While this has led to a rise in COVID-19 cases in some regions, doctors emphasize that the new strain is not fundamentally different from previous ones and there is no need to panic.

The NB.1.8.1 variant was first identified in international travelers and has been found in countries experiencing increased hospitalizations. The World Health Organization (WHO) notes that it spreads faster than other circulating strains but has not found evidence of more severe illness.

In Russia, four cases of the new variant have been confirmed. Rospotrebnadzor acknowledges the situation warrants “concern,” but the Ministry of Health maintains that existing COVID-19 prevention measures are sufficient, citing a stable situation in the country.

Experts clarify that the current outbreak is caused by a group of related subvariants rather than a single new strain. They predict a potential rise in COVID-19 cases in some countries, followed by a decline, but do not anticipate a wave comparable to the earlier stages of the pandemic.

The effectiveness of current vaccines against the new variant is under scrutiny. Alexander Gintsburg, director of the Gamaleya Research Center, admits that existing vaccines may offer limited protection against current strains, as new strains are not isolated in Russia and vaccines are not developed that would work against current variants of COVID.

Doctors emphasize that vaccination remains relevant, especially for those over 60, though access to vaccines is currently limited. One immunologist recommends the Konvasel vaccine, which targets a coronavirus antigen found in all strains.

Health officials reiterate the importance of preventive measures such as frequent hand washing, avoiding close contact with symptomatic individuals, and ensuring proper ventilation and humidity.
