　　On the morning of April 30th, Yang Baofeng, academician of the Chinese Academy of Engineering and vice president of the Chinese Medical Association, joined Li Lanjuan, a member of the Chinese Academy of Engineering and a member of the high-level expert group of the National Health Commission, to conduct in-depth exchanges on the next step of epidemic prevention and control in our province.

　　For the question of whether the patients concerned by the public are still infectious after being cured, Academician Li Lanjuan introduced that after receiving anti-viral treatment during the hospitalization of patients with new coronavirus, the new coronavirus will become “negative”. Normally "negative" means that the patient's sputum, nasopharyngeal swab and other respiratory specimens have negative nucleic acid tests, and the interval between the two tests should not be less than 24 hours. Regarding the course of antiviral treatment, she suggested that patients should receive at least one week of antiviral treatment after "negating", stop antiviral treatment prematurely, and the virus may be left in the body. Once the drug is stopped, it will "rejuvenate" , So the antiviral treatment should be extended a bit as well.

　　Academician Li Lanjuan said that our country now strictly stipulates that patients with new crowns who are discharged from the hospital will be negative if the nucleic acid test result is negative within a month of discharge. Generally speaking, this patient will no longer be contagious.

　　If conditions permit, serum new coronavirus IgG and IgM can be tested. "Generally speaking, if IgM is positive, it is in the current infection, then you need to continue treatment; if IgM is negative and IgG is positive, it means that it has recovered and is immune."

　　She believes that strictly following the relevant regulations should be no problem. Please rest assured that the new crown pneumonia patients will not be treated differently.
