(Fighting against New Coronary Pneumonia) Expert: Most of the people infected with Omicron have less symptoms of upper respiratory tract infection
China News Agency, Beijing, March 25th ( Reporter Ying Ni) Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital, said in Beijing on the 25th that most of the people infected with Omicron have upper respiratory tract infections and very little pneumonia.
On the same day, the Joint Prevention and Control Mechanism of the State Council of China held a press conference. At the press conference, Wang Guiqiang introduced the update of the new version of the diagnosis and treatment plan for the characteristics of the Omicron variant.
He pointed out that the previous version of the diagnosis and treatment plan emphasized that in a relatively confined space, prolonged exposure to high concentrations can lead to transmission, and this time it is clear that aerosol transmission can occur in a relatively confined space, that is, Airborne. This is an important feature of Omicron’s strong contagiousness and transmission through aerosol routes. In a relatively confined space, be sure to wear a mask for self-protection. At the same time, reduce aggregation, increase ventilation, and reduce the risk of aerosol transmission.
In response to the clinical manifestations, Wang Guiqiang said that there are many mild cases and asymptomatic infections in Omicron, and most of the patients have upper respiratory tract infections and few pneumonia. In fact, Omicron is mainly present in the upper respiratory tract, and the amount of virus in the lung is small, so the performance of pneumonia is not much, and the symptoms of the upper respiratory tract are more obvious. There are many similarities in clinical manifestations to influenza, such as coughing, sneezing, nasal congestion, etc., which need to be highly concerned.
When talking about how the new version of the new crown diagnosis and treatment plan can achieve “move forward”, Wang Guiqiang pointed out that in terms of diagnosis, the new version of the plan uses antigen detection as an important supplement to nucleic acid detection, especially at the level of management and control and at home. If the test is positive, it will be reviewed immediately, and the potential infected person will be identified earlier and quarantined in time to avoid further spread.
In terms of classified management, he said that the new version of the diagnosis and treatment plan emphasizes the centralized isolation and management of light cases, and it is not necessary to go to designated hospitals. This is to free up limited medical resources so that ordinary and severe patients can receive timely and effective treatment. For asymptomatic infections, the new version of the diagnosis and treatment plan will isolate them at the community level. (End)
