After this round of epidemic, people frequently see keywords such as positive initial screening, asymptomatic infections in , and confirmed cases. So, what is the difference between asymptomatic infections and confirmed cases? What are the differences in clinical manifestations? What treatment measures are taken for different types of infections? Today, Zhou Wei, head of Ningxia COVID-19 Diagnosis and Treatment Expert Group and director of the Autonomous Region People's Hospital, gave an authoritative answer.
Recently, with rounds of nucleic acid testing , confirmed patients and asymptomatic infections have appeared one after another. Experts said that the difference between asymptomatic infections and confirmed cases is that there are no respiratory symptoms and lung imaging changes in clinical practice. Although there are no relevant clinical symptoms, the nucleic acid test for asymptomatic infections is positive, and the infectivity is basically the same as that of confirmed cases, and it can still be transmitted to healthy people around you through respiratory droplets.
Ningxia COVID-19 Diagnosis and Treatment Expert Group Director of the Autonomous Region People's Hospital Zhou Wei:
The most important thing is that we refer to the nucleic acid CT value. The nucleic acid CT value represents the viral load of a patient, and it also indirectly reflects the infectiousness. Therefore, the infectivity of asymptomatic infected persons and confirmed cases is basically the same, so their harm is the same.
Ningxia's current epidemic transmission strain was clearly classified as two variant strains of the new coronavirus Omickron BA.5.2 and BA.2.76. The strain has strong transmission, strong occultness, relatively low virility, decreased pathogenicity, and relatively mild symptoms, so asymptomatic infections account for a high proportion. On the other hand, new coronavirus vaccine has a great protective effect on preventing severe illness and preventing death. With the large-scale vaccination of new coronavirus vaccine , the proportion of severe and critical illness after infection has decreased significantly, mainly mild or asymptomatic.
In view of the different clinical manifestations, asymptomatic infected people and confirmed cases must be classified and treated. Asymptomatic infected people and mild confirmed cases are mainly treated in temporary hospitals; ordinary, severe, and critical confirmed cases are admitted to designated hospitals. At present, Ningxia coordinates medical resources to ensure that all people infected with the new coronavirus have "collected all receivables". Experts said that asymptomatic infections generally do not need to receive special treatment during isolation and medical observation, but some cases may experience relevant clinical manifestations in the future and become confirmed cases.
