Asymptomatic and confirmed cases are both infected populations, but they differ somewhat in terms of clinical symptoms and management. An asymptomatic patient is considered in a sense to be in the latent phase of a confirmed case, or a population with a mildly confirmed case. Especially for novel coronavirus and its variant strains, early detection of asymptomatic infected persons is important for their own life and health, as well as for maintaining the public health safety of the society. 1. Asymptomatic infected persons 1. Clinical symptoms: Usually people who do not have or find themselves with symptoms such as fever, cough, sore throat, malaise, etc., and no imaging changes are found by CT examination. However, if a positive result is found when screening for novel coronavirus nucleic acid, the person can be called an asymptomatic infected person. 2. Treatment: Asymptomatic infected persons generally do not need to receive special treatment because there is no specific medicine for novel coronavirus, and treatment is needed according to the symptoms that appear. If you are asymptomatic now, you may not receive treatment for the time being. However, isolation and medical observation are still required, and routine blood work, CT imaging and antibody testing will be completed as required. Some of the population may subsequently develop relevant clinical manifestations, at which time it can be called a confirmed case. Confirmed cases 1. Clinical symptoms: It refers to positive virological test, along with clinical symptoms such as fever, cough or dry cough, sore throat, and abnormal blood or imaging test results. Confirmed cases can be classified into four types according to the severity: light, normal, heavy, and critical; 2. Treatment: Confirmed cases need to be isolated and treated in designated hospitals or prescribed places, with general treatment and medication as the main treatment. Along with bed rest, nutritional support and testing of vital signs, drugs such as PF-07321332/ritonavir tablets (Paxlovid), Ambavir monoclonal/romisil monoclonal injection, and Lianhua Qingfei capsule will be applied as appropriate for the confirmed population with novel coronavirus infection. It should be noted that asymptomatic infected persons still need to be isolated, observed, and have their signs tested according to the requirements of confirmed cases. Travel and normal life of such people will be restricted to a certain extent. If they are defined as asymptomatic infected, they need to promptly inform their community and contact the designated hospital with the help of staff to actively cooperate with further treatment measures.
