 A man has no abnormal symptoms since he was diagnosed with infection and discharged from hospital in Guangdong Province

Novel coronavirus pneumonia in Shaoguan province was treated by medical staff in the morning of February 28th, according to the forenoon of Guangdong. It has been recovered from the second peoples Hospital of North Guangdong, and has been discharged from hospital in February 28th. Up to now, novel coronavirus pneumonia has been diagnosed in 10 cases in Shaoguan. 9 cases have been cured and discharged, and 1 cases have been treated in hospital.

Discharged patient I, male, 26 years old, registered in Xinfeng, has lived in Shunde District of Foshan for a long time. He visited his relatives in Hong Kong from January 23 to 27 and returned to Fengcheng street of Xinfeng County on January 28. On February 9, he was hospitalized for coughing and pharyngeal pain and was isolated for treatment. On that day, the nucleic acid test was negative, and then the two nucleic acid tests were positive. He was diagnosed as a confirmed case. The patients were isolated and treated in Yuebei Second Peoples Hospital, a designated medical institution in Shaoguan City. According to the epidemiological survey, the case has a history of contact with the confirmed cases in Hong Kong.

The novel coronavirus pneumonia novel coronavirus pneumonia clinical treatment experts and medical staff of the two cases of joint efforts, careful treatment, careful care, the Shaoguan CDC for two times interval of 24 hours of virus nucleic acid detection, the results are negative, has been consistent with the national health and Health Committee issued by the office of the new coronavirus infection pneumonia diagnosis and treatment plan. Discharge criteria for confirmed cases in. The patients were discharged at the same time on the 28th, and the hospital ordered them to continue isolation observation for 2 weeks.

What is asymptomatic infection?

The novel coronavirus novel coronavirus infection was diagnosed in February 5th by the national health and Health Committee (Fifth Edition), which is published by the national health and Health Committee in February 5th.

Asymptomatic infections can also be a source of infection. The novel coronavirus infection in Peking Union Medical College Hospital is interpreted as the asymptomatic infection mentioned here does not mean that some people will never become symptoms after being infected with the new coronavirus and become a concealed poison in walking. It means that the infected person may also transmit the virus before incubation.

Li Xingwang, a member of the national medical expert group and chief expert of the infectious diseases diagnosis and research center of Beijing Ditan Hospital, said that asymptomatic infections were indeed found, mostly in family cluster cases. After close contact with patients, these asymptomatic infections themselves did not have obvious clinical manifestations such as fever, fatigue, pneumonia, etc.

In a paper published in the lancet, six infected children in a family in Shenzhen were statistically analyzed, and a child infected with the virus but without obvious symptoms was found. If the asymptomatic cases are common and these people can spread the virus, it will be more difficult to control the spread of the virus. The key to controlling SARS in that year was that there were very few asymptomatic cases, the researchers said.

Novel coronavirus is a newly discovered virus, which is generally susceptible to the virus in the crowd, explains Qiu Haibo, vice president of Zhongda Hospital Affiliated to Southeast University and critical medical expert. But it doesnt mean that everyone gets sick. There are several situations:

First, some people have enough self resistance to get rid of the virus.

Second, the virus can reproduce in some peoples upper respiratory tract, but these people have no symptoms, so-called asymptomatic infection.

Third, the light patients. They show signs of fatigue, low fever or dry cough.

Fourth, only a few patients will develop severe or critical illness.

For asymptomatic infections, no special treatment is needed, but isolation is needed. Jiang rongmeng, chief physician of the second Department of infection, Beijing Ditan Hospital Affiliated to Capital Medical University, said.

How likely are asymptomatic infections to spread the virus?

A novel coronavirus pneumonia was diagnosed in Anyang in January 27th after a woman was returned to Anyang from Wuhan in January 27th. The novel coronavirus asymptomatic infection was first reported in Hangzhou in January 29th. The patient went to Hangzhou from Wuhan to attend the meeting. When he arrived in Hangzhou, he did not have any disease, cough or fever. He looked like a healthy person. A few days later, several colleagues he had contact with began to develop symptoms. These patients who had contact with asymptomatic infected persons and were diagnosed had no history of living or traveling in Wuhan. Li explained that in terms of pathogenesis, asymptomatic infection, since it has a virus, may cause transmission. But from the actual situation, since the patient is asymptomatic infection, the disease is relatively light, and the severity of the disease is related to the amount of virus in his body. In other words, asymptomatic infected people carry less virus, so the transmission power will be weaker than that of patients.

Jiang rongmeng, on the other hand, explained the weak transmission of the virus in asymptomatic patients. Those who are positive for viral nucleic acid but have no clinical symptoms may be infectious, but they should be relatively weak. As a respiratory disease, pathogens can be excreted only when symptoms appear. For example, by coughing and sneezing, patients can discharge these pathogens into the surrounding environment. If he has no symptoms, it is generally considered that his infectivity is very weak even if it has.
