Neocoron refers to novel coronavirus pneumonia. There is no authoritative information on the turnaround time for novel coronavirus pneumonia, which may be weeks, months, or longer if the condition is critical. New coronavirus pneumonia is an acute infectious pneumonia. At present, there is no authoritative information on how many days it will take for the new type of coronavirus pneumonia to turn negative. It mainly depends on the severity of the disease, physical fitness and other factors, and in general, most of the patients will be able to turn negative in a few weeks or a few months or so after timely treatment. However, for patients in critical condition, there is a possibility of not being able to turn negative, which is relatively dangerous and has a poor prognosis. Secondly, severe patients may also have complications such as pulmonary fibrosis and acute respiratory distress syndrome, which require a longer time for recovery. To summarize, when the new coronavirus pneumonia is detected, it is necessary to go to the hospital in time and cooperate with the doctor to carry out standardized treatment. Normally, you need to actively receive the new coronavirus vaccine and take all protective measures. Tip: In this article, “new coronavirus pneumonia” and “new coronavirus pneumonia” have been renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
