The pathogenicity of Omicjon is weakened, and most of them are asymptomatic or mild after infection. Are only coughing and fever asymptomatic? Will "yang" be "yang" again once? Around the hot issues of public concern, the relevant experts of the joint prevention and control mechanism of the State Council gave professional answers.

The pathogenicity of Omicjon is weakened, and most of them are asymptomatic or mild after infection. Are only coughing and fever asymptomatic? Will "yang" be "yang" again once? Around the hot issues of public concern, the relevant experts of the joint prevention and control mechanism of the State Council gave professional answers.

1, Q: the new crown virus positive infection is only cough, fever, no symptoms?

Answer: If the positive infection is only cough, fever and no lung infection, it can be classified as a mild case, but it is not asymptomatic. According to the current national case data, asymptomatic and light after infection with Omicjon account for more than 90%. According to the current definition, an asymptomatic infected person is a person who has tested positive for the etiology of the new coronavirus and has no relevant clinical manifestations, such as fever, dry cough, fatigue, sore throat, decreased smell (taste), diarrhea and other self-perceivable or clinically identifiable symptoms and signs, and who has no imaging features of new coronavirus on CT imaging.

Mild patients can be characterized by low-to-low fever, dry throat, sore throat, nasal congestion, runny nose and other symptoms of upper respiratory tract infection, as well as fatigue, smell (taste) disturbance and other symptoms, but no pneumonia.

2, ask: "Yang" once will again "Yang"? How long may secondary infection occur?

A: After being infected with a new coronavirus, the body's immunity will play a protective role. However, Omicjon may rapidly mutate into new subbranches, resulting in strong immune escape ability, and the convalescent can not completely avoid secondary infection.

However, foreign statistics show that if you have been infected with Omicjon, regardless of symptoms or not, the probability of secondary infection within 3 to 6 months is quite low, and most people will not be re-infected with Omicjon for a long time.

For individuals, the best thing to do during an epidemic is to put in place protective measures, including wearing masks, paying attention to hand hygiene, keeping a social distance, and actively vaccinating against the new coronavirus to reduce the risk of infection.

Q: Does repeated infection make the symptoms worse?

A: There is no conclusive opinion that superinfection will have a more serious clinical outcome. Judging from the current cases, even if individual patients have a tendency to worsen their symptoms during repeated infections, this proportion is very low. The pathogenicity of Omicjon virus is weakening, and the probability of severe illness is very low, whether it is the first infection or re-infection.
