Omickron is weakening its pathogenicity, and most of them show asymptomatic or mild after infection. Is it asymptomatic to just cough and fever? Will "yang" be "yang" again after one time? Focusing on hot issues of public concern, relevant experts from the State Council’s Joint Prevention and Control Mechanism gave professional answers.
1. Question: Is it considered asymptomatic if a positive infection of the new coronavirus infection?
Answer: If a positively infected person only has a cough or fever and does not have lung infection , it can be classified as a mild case, but it is not asymptomatic. Judging from the current national case data, asymptomatic and mild cases account for about 90% of the cases after infection with Omickron.
According to the current definition, asymptomatic infected person refers to those who have positive etiology tests for the new coronavirus and have no relevant clinical manifestations, such as fever, dry cough, fatigue, sore throat, decreased sense of smell (taste), diarrhea, etc., which can be self-perceived or clinically identifiable, and CT imaging does not have the imaging characteristics of the new coronavirus pneumonia.
Military patients may show symptoms of upper respiratory tract infection such as moderate-low fever, dry throat, sore throat, nasal congestion, runny nose, as well as symptoms such as fatigue and olfactory (taste) disorders, but there is no pneumonia .
2. Question: Will "yang" be "yang" again after one time? How long does it take to cause secondary infection with ?
Answer: After infection with the new coronavirus once, the immunity formed by the human body will play a certain protective role. But Omickron may quickly mutate into new sub-branches and develop strong immune escape ability. Recovered people cannot completely avoid secondary infection.
However, foreign statistics show that after being infected with Omickron, regardless of whether they have symptoms or not, the probability of secondary infection within 3 to 6 months is quite low. Most people will not repeatedly infected with Omickron for a considerable period of time.
For individuals, the best way to do this during the epidemic is to implement protective measures, including wearing masks, paying attention to hand hygiene, maintaining social distance, etc., and actively vaccinating new coronavirus vaccine to reduce the risk of infection.
3. Question: Will repeated infection make the symptoms more serious?
As of the moment, there is no conclusion that repeated infections will lead to more serious clinical results. Judging from the current cases, even if some patients tend to worsen their symptoms during repeated infections, this proportion is very low. The pathogenicity of the Omickron virus is weakening, and the probability of severe illness is very low whether it is the first infection or the re-infection.
