The World Health Organization is worried about the rapid spread of the new coronavirus outside China, most of all about the presence of infections that have no history of travel in China or have no access to diagnosed patients. "Not only is the number of infections increasing, but there are also a variety of ways of transmission "... The strange symptoms of the new coronavirus pose a serious challenge to prevent transmission of the virus.
Female asymptomatic transmission of family
A 20-year-old woman from wuhan, hubei province, who visited relatives in anyang, henan province,675 kilometers from wuhan, on january 10th, passed the new coronavirus on to five relatives without symptoms, according to essay, published in the journal of the american medical association.
Doctors isolated it for coronavirus testing, initially negative, but later positive. Moreover, as of february 11th, the woman still had no symptoms, a tomography scan of the breast was normal, no fever, no cough, and no respiratory symptoms such as stomach and sore throat. This seems to provide new evidence that the virus can infect others without symptoms. Li xingwang, a member of china`s national medical expert group and chief expert at the center for diagnosis, treatment and research of infectious diseases at beijing earth altar hospital, said some patients with new coronavirus had no pneumonia and remained infectious.
Positive reaction after cure days
Sichuan Health Commission confirmed 21, Chengdu Wangjiang Jinyuan District after a new coronavirus infection cured, home isolation on the 10th, that is,19th reexamination of the positive reaction.
Zhao Jianping, head of the Wuhan Medical Treatment Group and director of the Department of Respiratory and Critical Care Medicine at Tongji Hospital of Huazhong University of Science and Technology, said the judgment of patients leaving hospital should be careful. He pointed out that some patients were discharged from hospital, two nucleic acid tests were negative, but a few days later began to have a fever, nucleic acid tests are positive, so the discharge cases should be isolated at home for 14 days.
Wuhan authorities 22 issued a notice, requiring the new coronavirus cured after discharge from hospital and then fixed-point isolation for 14 days, may be due to the above considerations? According to chinese media, in changde, hunan, shandong junan have been discharged several days after re-examination of the positive situation.
Early coronavirus
A woman in her 60s in northern TW has been diagnosed with a new coronary pneumonia, the TW central epidemic command center has announced. No history of going abroad within 2 years, disease 29 days before diagnosis. Although the woman met with her daughter, who returned to TW from Hangzhou, China, on January 6, she was less likely to study because of her exposure time and onset time.
TW experts analyzed that the virus in this case was a fairly early new coronavirus, unlike the new coronavirus infected in Japan and South Korea. The doctor confesses that the source of the infection in this case is a mystery.
The woman`s granddaughter was diagnosed on the 21st, and the two had been in contact for five minutes when they visited the hospital on February 12. But doctors have analyzed that the likelihood of infection in five minutes is present, because the woman`s symptoms are so severe that her granddaughter may have to be close enough to talk to each other, closer than the distance between a paramedic and a patient.
30 days or more before being diagnosed
One was diagnosed 34 days after returning home and the other 94 days after suspected contact with the source of the infection.
