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.

Health tips

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.

Health tips

1, enhance self-prevention awareness. If possible, try to use central heating; When using coal stoves and charcoal fires indoors for heating, the coal should be burned out and not covered; Don't install gas water heater in the bathroom, and pay attention to ventilation when using gas water heater.

2, regular equipment maintenance. Regularly maintain the pressure reducing valve and rubber tube of gas and gas water heater, and replace them in time if any problems such as damage, corrosion and air leakage are found.

3. Install a carbon monoxide alarm. Carbon monoxide is colorless and odorless, and early leakage is difficult to detect. It is suggested to install a carbon monoxide alarm and check and maintain it regularly to ensure the normal operation of the detector.

4. Beware of poisoning in the car. Don't idle in a closed car for a long time to warm up or turn on the air conditioner; When driving closed for a long time, it is necessary to properly open the window for ventilation.

5. Enhance emergency response capability. In case of carbon monoxide poisoning, you should immediately open the window for ventilation, turn off gas/gas cookers, pipeline gas and other facilities and equipment, move the patient to a place with good ventilation and fresh air, pay attention to keep warm, and call 120 for emergency rescue.

Norovirus infection

Norovirus is highly contagious, people of all ages are generally susceptible, and there may be a cluster epidemic in crowded places. The main symptoms are mild, such as vomiting and diarrhea, followed by nausea, abdominal pain, headache, fever, chills and muscle pain.
