World Health Organization Director General Tan Desai said on the 13th that some countries are considering lifting restrictions on home quarantine during the epidemic. Existing experience shows that six specific standards should be considered before lifting restrictions.
Tan Desai said at the regular press conference that day, WHO is about to release the revised new crown prevention and control strategy recommendations. The recommendation includes 6 criteria that countries should consider before lifting outbreak restrictions:
- the spread of the outbreak has been controlled.
- the health system has the ability to detect, detect, isolate and treat each case and track each contact.
- health facilities The risk of outbreaks in special environments such as homes and nursing homes has been minimized.
- preventive measures have been taken in workplaces, schools and other places where people must go.
- the risk of imported cases is controllable.
- the community has adapted through adequate education, participation and authorization The epidemic “new normal”.
Tan Desai said that the experience of several countries has given us a clearer understanding of the new coronavirus, including how this virus behaves, how to stop it, and how to treat it. For example, the new coronavirus is more likely to spread in crowded environments such as nursing homes. The number of confirmed cases in some countries doubles every 3 to 4 days, and its lethality is 10 times that of the 2009 pandemic.
Tan Desai emphasized that the spread of the new coronavirus is obviously accelerated, but the deceleration process is much slower. “In other words, the (number of cases) decline is much slower than the rise. This means that restrictions must be removed slowly and in a controlled manner, and cannot be achieved overnight.” He believes that only correct public health measures, including Only with a strong ability to track contacts can restrictions be lifted.
At the same time, many low- and middle-income countries in Asia, Africa, and Latin America have large populations of poor people, and it may not be practical for them to emulate home isolation and other restrictions in some high-income countries. Tan Desai suggested that each country should implement a comprehensive set of measures to slow the spread of the epidemic and save lives, so as to achieve a stable state with low or no spread. At the same time, the vulnerable groups should be helped to obtain routine basic health services, so that medical resources can achieve a certain balance between responding to the new coronavirus epidemic and other diseases. He stated that “ultimately completely blocking the spread of the virus will depend on the development and provision of a safe and effective vaccine.”
