There are no new deaths reported.

One new suspected case was reported, which was an imported case from abroad (in Shanghai).

Liu Lei, director of the National Center for Clinical Research of Infectious Diseases and secretary of the Party Committee of Shenzhen Third People's Hospital, reminded five points to pay attention to when doing nucleic acid testing in an exclusive interview with Jingbao:

Do not chew gum, betel nut or drink alcohol;

For those with sensitive pharynx, it is best not to eat two hours before the test;

Keep one meter away and don’t chat;

Do not place personal items on the testing table;

It is best not to make any sound during the test, and do not shout "ah".

If the person being sampled is a positive patient, he or she may exhale a large amount of virus when shouting "ah", and aerosols may be formed in the sampling area, causing direct pollution to the sampling point environment. When the next person is tested, the virus-carrying aerosols may inevitably be inhaled into the respiratory tract. During the sampling process, it is recommended that you do not shout or take deep breaths, but just take off your mask and open your mouth wide.

Real nucleic acid testing

It’s not as easy as you think!

Wash your hands! Wash your hands! Wash your hands!

China CDC issued an important reminder on March 22. Wu Zunyou, chief epidemiologist of the Chinese Center for Disease Control and Prevention, introduced at a press conference of the State Council's Joint Prevention and Control Mechanism that in the past two years of COVID-19 prevention and control, it was found that the new coronavirus may cause infection through the route of "transmission from objects to humans", but its role in the spread of the epidemic is very limited.

Washing hands can simply and effectively cut off these transmission routes. Keeping hands clean and hygienic can effectively reduce the risk of infection with the new coronavirus.

In daily work and life, people's hands come into contact with objects contaminated by bacteria or viruses. If they fail to wash their hands correctly and in time, the bacteria or viruses on their hands can enter the human body through touching the mouth, eyes, nose, etc.

Respiratory infectious diseases are mainly transmitted through close-range droplets, and can also be spread through hand contact with contaminated surfaces. Therefore, in the prevention of COVID-19, we emphasize hand hygiene as an important personal protective measure.
