Fifty-one recoverers in South Korea tested positive: Fuyang was not the result of reinfection or the reactivation of the virus.

South Korea's Ministry of Health said Monday that 51 patients with xinguan pneumonia from Daegu and Gyeongsang North Road have tested positive again after recovering from isolation, Yonhap reported. The Centers for Disease Control and Prevention said it could be the result of the virus reactivating, rather than the patient being reinfected,
reported.
discharge is not equal to 100% cure from the current discharge standards and cure degree, a large number of people's lung inflammation is still in the process of absorption, can not be said to be completely achieved clinical healing, but in clinical judgment has reached the discharge standards, there may be intermittent detoxification phenomenon.
therefore, discharge does not mean 100% cure, just that the patient no longer needs to be treated in hospital, but still need to be isolated at home for a period of time.
might ask, why not wait until 100% sure you're cured and discharged from the hospital? In fact, even the common cold, the current medical technology can not be 100% to solve it, let alone for this we have not seen, do not know much about the new type of pneumonia.
also, long-term hospital stay is also unrealistic, irrational, stay in the hospital for a long time, on the one hand will increase the risk of infection in the hospital (the hospital virus, bacteria and other pathogens are more dangerous than the home);
Fuyang patients have a low probability of reinfection, therefore, retesting nucleic acid positive often means that discharged patients are still in a "intermittent detoxification, drug" process, refers to the body of the virus in the fight with the human body, after the defeat of the state of death, generally do not belong to reinfection.
Zhong Nanshan academician pointed out that the general infection of patients, their body will produce the corresponding protective antibodies, if the patient has a new coronary pneumonia cure, antibody testing to a strong positive, his re-infection is very low.
as for some of the viruses that remain in the feces and intestines, it remains to be seen whether it will ever be transmitted to others again.
"Fuyang" patients will also be infected with others is possible.
according to the growth and transmission characteristics of microorganisms, human infection with the virus will produce the corresponding protective antibodies, generally not contagious.
laboratory monitoring found that young people can produce antibodies within two weeks, and even if nucleic acids test positive, the risk of transmission is lower. although the risk is low
, for some older people and the frail, it takes longer to produce antibodies, may carry the virus for a longer period of time, or become a source of infection due to constant detoxification.
the "Fuyang" patients have taken corresponding measures of the national diagnosis and treatment program for Fuyang and discharge standards have clearly defined, requiring patients to be discharged from the hospital, concentrated medical observation for 14 days.
will carry out monitoring during this period, if the discharged patients found antibodies, nucleic acid test negative, before the health to the community.
if the nucleic acid test is positive, in the prevention and control should be in accordance with the source of infection to manage, to take strict medical observation to check whether the recurrence or infectious. On the afternoon of February 25,
, Song Tie, deputy director of the Guangdong Provincial Center for Disease Control and Prevention, pointed out that 14% of discharged patients in Guangdong now have "fuyang" phenomenon, which has not continued to infect others through centralized medical observation;
"Fuyang" there are interference factors, do not rule out the error may be at present, Fuyang phenomenon still exists in a variety of interference factors, nucleic acid detection is only recently developed, reagents themselves, detection methods, the impact on the human body, etc. may cause errors.
Zhong pointed out that it is recommended that discharged patients at home isolation detected positive nucleic acid, 24 hours later need to be tested, at this time may turn negative.
if both were positive, medical attention is required in time for further treatment.
