From the point of view of the WHO, the corona variant XBB.1.5 is probably the most contagious so far – a risk analysis is currently underway. So far, the spread has mainly been observed in the USA and Europe. But the organization is also concerned about the corona wave in China.
The World Health Organization (WHO) is concerned about the new coronavirus variant XBB.1.5. The variant discovered in October is more easily transferrable than any of the previously known variants, said WHO corona specialist Maria van Kerkhove. According to the available genetic analyzes of the virus, it is spreading primarily in the USA and Europe and has already been detected in 29 countries. It is a subset of the omicron variant that has been circulating since late 2021. A risk analysis is in progress and will be published shortly, said van Kerkhove.
The US health agency CDC estimated earlier this year that XBB.1.5 accounted for around 40.5 percent of all new infections in the US in the week before the turn of the year. “In recent weeks, reports of hospitalizations and pressure on health systems have increased, particularly in regions in the northern hemisphere, where respiratory diseases such as influenza are also rampant,” said WHO chief Tedros Adhanom Ghebreyesus.
With a view to the corona wave in China, the WHO continues to press for more information from the Chinese authorities. Tedros expressed understanding for countries that have introduced testing regulations for travelers from China. “We continue to urge China to provide faster, regular and reliable data on hospital admissions and deaths, and more comprehensive real-time sequencing of viruses,” Tedros said. “Because the virus circulation in China is so high and comprehensive data is not provided, it is understandable that some countries are taking measures to protect their own citizens.” The requirement for tests are not travel restrictions, said WHO emergency response coordinator Mike Ryan.
He also criticized the narrow Chinese definition for the statistics of corona deaths. Only infected people who die of respiratory problems are counted. According to the WHO, however, the complications that can lead to death from Covid-19 are much more extensive. The Chinese definition is far too narrow, Ryan said. The WHO therefore assumes that the true number of Covid 19 deaths is significantly higher.
