COVID-19 enters 4th year with successes, but new threats CIDRAP

As the pandemic enters its fourth year, the world is in a better place with managing the disease but still faces threats from inequities for accessing tools to battle COVID-19, intense transmission in several countries, and the emergence of another highly transmissible Omicron subvariant, the head of the World Health Organization (WHO) said today.

In a related development, the WHO today shared details about its virus evolution advisory group's assessment of viruses circulating in China and said the experts are also assessing the Omicron XBB.1.5 subvariant, which is quickly becoming dominant in the United States.

The coronavirus Omicron strain XBB.1.5, which has become the dominant strain in the U.S. in just a matter of weeks, could drive a new wave of cases, a World Health Organization official told reporters Wednesday.

“We are concerned about its growth advantage, in particular in some countries in Europe and the Northeast part of the United States, where XBB.1.5 has rapidly replaced other circulating sub-variants,” said Maria Van Kerkhove, the WHO’s Covid-19 technical lead.
