The World Health Organization said symptoms of the new coronavirus variant “PJ.2.1” may resemble those of the common cold and flu. However, it stressed that symptoms alone are not enough to identify the virus and that diagnosis requires specific tests. The organization warned of a growing risk of the variant spreading globally and said it is monitoring its evolution closely, while scientists do not currently expect it to cause a new wave of infections. The variant has numerous mutations and a strong ability to bind to “ACE2” receptors, but it still lacks the ability to evade the immune response.
