According to the official weibo news of the Shenzhen Municipal Health And Health Commission, on February 1, 2020, Shenzhen Third People’s Hospital revealed that the institute’s liver disease research found that some of the new coronary virus infection of pneumonia confirmed patients in the feces tested positive for 2019-nCoV nucleic acid (new coronavirus), It is likely to indicate the presence of live viruses in the feces.
What does this discovery mean a third form of transmission for the new coronavirus? How do we respond? The Beijing News reporter interviewed Zhang Qiwei, a member of the Chinese Society of Microbiology’s Special Committee on Virology, Professor of Microbiology at the Faculty of Medicine of the University of Hong Kong, and Professor of Biosecurity Laboratory, Southern Medical University.
Beijing News: What does it mean to test positive for 2019-nCoV nucleic acid (new coronavirus) in the feces of pneumonia patients infected with the new coronary virus?
Zhang Qiwei: Although no live virus has been detected, but nucleic acid test positive, but the probability of live virus is very high. As a result, the new coronavirus may also be transmitted through feces, or by the use of aerosols containing the virus.
Beijing News: Are other infectious diseases spread through feces?
Zhang Qiwei: Very much. Respiratory adenoviruses like the one I studied can be transmitted through feces.
Beijing News: How does the virus spread to people through feces?
Zhang Qiwei: The virus into the intestines, in the intestines may also multiply, and then through the bowel stool out. When discharged, there are at least two ways to spread to people. First, the feces touched a part of the pants, and then the hand touched this part of the pants, and then touched the nose or mouth, the person will be poisoned.
The second way, infected patients go to the toilet flush toilet, flush toilet water generally has a greater impact, containing the virus of feces may be volatile into the air. If the toilet is closed, the ventilation effect is not good, someone is right next to the toilet, it is possible to be infected by breathing.
Beijing News: What proportion of this mode of transmission in all the ways of transmission of the virus?
Zhang Qiwei: Not more than half. Many viruses are transmitted through the respiratory tract. Most of the passage stoic transmission is enterovirus, the virus that causes enteritis. Most of the respiratory virus is still transmitted through droplets, contact transmission, feces transmission accounted for a large proportion.
But it should not be taken lightly, because if the patient’s symptoms are more serious, the number of viruses in his feces will be very large, the toilet process of the virus once released into the air will infect more people. Toilets, especially public toilets, can be a very dangerous source of transmission.
Beijing News: So how do we deal with it?
Zhang Qiwei: Before just told everyone to wear a mask, to wash their hands frequently, to the table, bed, chairs and so on disinfection. Now, the disinfection of toilets and toilets may be on the agenda.
Toilets used by new coronary pneumonia patients or suspected patients need to be thoroughly disinfected with disinfectant, and toilets must be ventilated. If the patient does not do well after use disinfection, the public toilet will become a source of transmission. Therefore, it is necessary for the relevant government departments to do a good job of guidance, public toilets to do a good job of disinfection, cut off the distribution of feces.
Beijing News: What disinfectant should be used to flush the toilet (toilet), 84 disinfectant can be?
Zhang Qiwei: Yes. Those disinfectants on the market are fine.
