Asymptomatic infected persons are those who have been infected with the relevant pathogens but have no relevant clinical symptoms and signs, and do not require special treatment but need to be isolated for observation.
Taking the current epidemic of C.pneumoniae as an example, asymptomatic infected persons are those who are positive for C.pneumoniae nucleic acid test results, but the patients do not have clinical symptoms such as fever, malaise, dry cough, etc., and there is no relevant change in the imaging characteristics of CT of the lungs.
Asymptomatic infected persons should be placed in centralized isolation for observation for 14 days, and can be released from centralized isolation if two consecutive samples with a time interval of at least 24 hours have negative nucleic acid test results. If the result is positive and there is still no clinical manifestation, the centralized isolation observation should be continued until two consecutive nucleic acid test results are negative before the centralized isolation can be lifted.
Asymptomatic infected persons should also undergo routine blood tests, lung CT tests and antibody tests during the period of centralized isolation observation. If symptoms or other signs that meet the diagnostic criteria occur, the case will be confirmed and must be transferred to a designated institution for standardized treatment.
Asymptomatic infected persons should be released from centralized isolation observation for 14 days of home isolation observation, and should return to the designated medical institution for follow-up in the second and fourth weeks.
Asymptomatic infected persons do not need special treatment because they are asymptomatic, dynamic monitoring of relevant indicators can be, but still have a certain degree of contagiousness, so must be isolated in accordance with the provisions of the observation.
