For asymptomatic infected people in COVID-19, they have been to epidemic areas and high-risk places in the past two weeks, and have had contact with infected people in the past two weeks, resulting in clustered cases. However, the patient had no obvious symptoms, and no viral pneumonia was found in lung CT, but the nucleic acid test was positive, so he was infected with novel coronavirus.
Warm reminder that asymptomatic infected people mainly refer to those who have no relevant clinical symptoms (such as fever, cough, sore throat and other symptoms and signs that can be perceived by themselves or recognized by clinic), COVID-19 etiology (usually referring to nucleic acid detection) in respiratory tract and other samples or positive serum specific immunoglobulin M(IgM) antibody detection.
Do asymptomatic infected people in COVID-19 need treatment? An asymptomatic infected person in COVID-19 refers to a patient who has no clinical symptoms, no symptoms of fever and respiratory infection, but is positive for novel coronavirus nucleic acid, and still contains novel coronavirus in his body, which can be transmitted to healthy people through respiratory droplets and close contact.
According to the management method and treatment plan of novel coronavirus, asymptomatic infected people in COVID-19 need centralized isolation, unified management and unified treatment. For the treatment of asymptomatic infected people in novel coronavirus, refer to the treatment of mild novel coronavirus.
Can asymptomatic infected people in COVID-19 be infected? It is contagious.
Although asymptomatic infected people in COVID-19 have no related symptoms, they are positive for nucleic acid detection and also carry COVID-19 virus, which can be transmitted to healthy people through respiratory droplets and close contact. Therefore, we can know that asymptomatic infected people in COVID-19 are contagious.
According to the requirements of epidemic management, close contacts and sub-close contacts should also be investigated for asymptomatic infected people, and high-risk groups should be screened and corresponding on-site control measures should be taken. Close contacts and sub-close contacts of asymptomatic infected persons take the same control and screening measures as confirmed cases.
4 The differences between asymptomatic infected people and confirmed patients in COVID-19 mainly include the following points:
For asymptomatic infected people in COVID-19, if the nucleic acid test is positive and symptoms have appeared, or after a period of observation, symptoms such as cough, fever and fatigue appear, it is diagnosed as a confirmed case. The infected person has no clinical symptoms, but the lung CT examination has lesions, which can also be diagnosed as a confirmed case.
Generally speaking, when asymptomatic infected people in COVID-19 need centralized isolation medical observation, they should have routine blood examination, CT image examination and antibody detection. If there are related symptoms or signs in the follow-up and meet the diagnostic criteria of confirmed cases, they should be corrected as confirmed cases within 24 hours.
Confirmed cases mainly refer to the clear diagnostic criteria according to the diagnosis and treatment plan, that is, the virological examination is positive, and there are clinical symptoms or abnormal blood routine and imaging examination. Clinical severity includes four types: mild, ordinary, severe and critical.
