Klug, director of the European Regional Office of WHO, 11, said in the Danish capital of Copenhagen that the variant COVID-19's drug is spreading across the European region from west to East, and the multinational medical and health system is facing challenges. Kluge said at an online news conference held on the same day that among the 53 countries in the WHO European region, 50 countries have reported cases of Omicron virus infection, and 26 countries have new confirmed cases every week, exceeding 1% of their total population. Due to the unprecedented transmission speed and scale, the number of new crown inpatients is increasing, and the medical and health systems and services in many countries are under great pressure. Some studies predict that more than 50% of the population in Europe will be infected with the Omicron strain in the next 6 to 8 weeks. Kluge warned that the Omicron strain would pose a more serious threat to countries with low vaccination levels. He called on all countries to take practical actions according to their respective circumstances. In countries that have not been impacted by the Omicron strain, emergency epidemic prevention measures should be taken immediately, including wearing masks, strengthening testing, isolating those with symptoms, strengthening vaccination, etc; In countries that have been affected by the Omicron strain, the top priority is to protect vulnerable and vulnerable groups and minimize interference with the medical and health system and basic medical services. Kluger said that it is effective to strengthen the vaccination of new crown vaccine, expand the scope of mask use, maintain ventilation in crowded or closed places, and use new diagnosis and treatment methods, whether for delta virus or Omicron virus. The primary goal is to achieve "vaccine sharing and solidarity" across age, sector, border and political boundaries. (outlook new era)
