In 2023, Wenzhou CDC issued 1 health risk warning. The latest news of epidemic situation in Wenzhou, Zhejiang on February 9, 2020.

Winter is the high incidence period of COVID-19 infection, and the overall risk level is high. XBB and BQ. 1 are new variant branches of Omicron, which have become dominant strains in some European and American countries, mainly showing enhanced transmission and immune escape ability. However, foreign data show that there is no significant difference between the pathogenicity and the previous strains. In countries where XBB and BQ. 1 are prevalent, the severity rate and mortality rate have not increased.

The trend of disease control in China shows that it is extremely unlikely that XBB series variants including XBB. 1.5 will cause a large-scale epidemic in China in the short term. However, with the arrival of the Spring Festival, the cross-regional mobility of personnel will increase significantly, so we should pay attention to the risk of epidemic spread.

Non-occupational carbon monoxide poisoning

Winter is the high season of carbon monoxide poisoning. In the cold winter, some citizens will use coal stoves for cooking and heating. If there is poor ventilation and insufficient oxygen supply, a large amount of carbon monoxide can be produced indoors. Sleeping in the car after turning on the air conditioner in winter may lead to carbon monoxide poisoning.
