OK, I can't now find the article I read that said there actually are new variants currently in China, (I didn't know in advance that I would be posting about it, or I'd have taken a note. If it appears soon, I will add a link) but a lot of experts are saying that China has not been sharing with other countries the genetic analysis of CoVid samples, and have cut down on sampling, so Chinese official figures may be a bit economical with the details. Also, the larger the numbers of infections, the more variants are likely to appear, and vaccination uptake does seem to be low in China.
Dated 21st December. "While many other nations vaccinated their populations in 2021 and boosted in 2022, rates of vaccination in China are comparatively low: only about 50% of the population have received three shots. China has only recently been encouraging the vaccination of the elderly and vulnerable.
The true extent of Covid-19 in China is now unknown, given the fall in testing. Other countries have learned the painful way that pretending Covid-19 doesn’t exist doesn’t mean the disease disappears. Experts following the situation estimate that 60% of the Chinese population (accounting for 10% of the world’s population) will be infected in the next 90 days. Given these infection levels and the population’s low immunity, deaths could rise to close to 9,000 a day by the end of March.
But like the true number of Covid cases, China’s official death toll isn’t reliable right now. The Chinese government isn’t reporting Covid-19 deaths: as crematoriums fill up, officials are staying quiet.
