WHO officials say the risk to public health is currently low and existing vaccines continue to provide protection.
However, authorities warn that Covid cases and other infections may increase this winter.
Respiratory viruses such as influenza, respiratory syncytial virus (RSV), and childhood pneumonia are also on the rise in the Northern Hemisphere.

omicronIt has been the dominant variant worldwide for some time.
WHO is currently monitoring a number of “variants of concern” linked to Omicron, including JN.1, but none of these are yet considered concerning.
It is predicted that it may cause an increase in coronavirus cases
JN.1,USAIt is now the fastest-spreading variant in the country and accounts for 15 to 29 percent of infections, according to the Center for Disease Control and Prevention (CDC).
EnglandThe Health Security Agency also said that JN.1 currently accounts for around 7 per cent of positive Covid cases analyzed in the laboratory and that it will continue to monitor all data on this and other variants.
The rapid spread of JN.1 is probably due to the fact that it has an additional mutation in the spike protein to that of the BA.2.86 variant from which it derives.
In WHO's risk assessment, it was stated that "This variant, especially in countries entering the winter season, as well as the increase in other viral and bacterial infectionscoronavirus"It is predicted that it may cause an increase in cases."
According to the WHO, there is still limited evidence on how well JN.1 can overcome the immunity conferred by vaccines.
There is no evidence that this variant makes people sicker than previous ones.
But WHO officials say more studies are needed to determine the health impact of this variant, as the number of countries reporting data on people admitted to hospital with Covid has decreased significantly.
