Cases of a new subvariant of “Omicron” – “Jenny” were recorded in Ukraine


During January, 9 cases of a new subvariant of the Omicron coronavirus strain – JN.1 (“Jenny”) were registered in Ukraine.

As reported by the Chief State Sanitary Doctor of Ukraine Ihor Kuzin, they were found in five regions.

“Three cases – in Sumy Oblast, two each – in Volyn and Cherkasy Oblasts, and one each – in Rivne and Zaporizhia Oblasts.

The SARS-CoV-2 virus is constantly mutating and evading the immune response, that is, it attacks weakened immunity more quickly, so even previously vaccinated people can get sick. However, the immunity acquired after vaccination reduces the risks of complications during the disease.” – he noted.

Among the patients, only one person had two vaccinations against COVID-19.

In most cases, the disease had a moderate or mild course and only one person was hospitalized. The age of the patients is from 27 to 73 years.

It was possible to single out cases of the JN.1 subvariant in Ukraine thanks to sequencing – a special laboratory study that allows for the genetic decoding of the virus and the detection of mutations in its genome.

“Jenny” was first discovered in the USA in September 2023. The WHO has classified it as a subvariant of Omicron, which is “of concern” due to “its rapid spread”.

According to the US Centers for Disease Control and Prevention (CDC), as of January 5, JN.1 accounted for approximately 62% of all SARS-CoV-2 cases.

The WHO noted that the risk of “Jenny” to the population is low. In addition, existing vaccines still protect against the new subvariant.

Earlier, the Ministry of Health reported that 12 million Ukrainians had not completed the course of vaccination against COVID-19.
