What does it mean if the faeces of patients with New Coronavirus are positive for nucleic acids? Beijing News 02-02 08:42 Reading count: 630,000+
Beijing News News (Reporter Xiao Long Ping) According to the Shenzhen health committee official micro-blog messages, 2020. February 1, Shenzhen Third People's Hospital said the hospital liver disease research Institute found that in some novel coronavirus A positive 2019-nCoV nucleic acid (new coronavirus) was detected in the stool of patients with viral-infected pneumonia, which is likely to indicate the presence of live virus in the stool.
What does this discovery mean, and does it mean that a new type of transmission of the new coronavirus has occurred? How should we respond? The Beijing News reporter interviewed Zhang Qiwei, a young member of the Virology Committee of the Chinese Society of Microbiology, a professor of the Department of Microbiology at the University of Hong Kong Medical School, and a professor of the Biosafety Laboratory of Southern Medical University.
Beijing News: 2019-nCoV nucleic acid (new coronavirus) positive was detected in the stool of patients with pneumonitis infected by the new coronavirus, what does this mean?
Zhang Qiwei: Although no live virus has been detected, only the nucleic acid test is positive, but the probability of live virus is very high. Therefore, it is also possible that the new coronavirus is transmitted through the fecal route, or re-transmitted through the formation of aerosols in the feces containing the virus.
Beijing News: Do other infectious diseases spread through feces?
Zhang Qiwei: Very many. Respiratory adenoviruses like my research can be transmitted through feces.
Beijing News: How does the virus spread to people through feces?
Zhang Qiwei: When the virus enters the intestine, it may still multiply in the intestine and then excreted through stool. After expulsion, there are at least two ways to spread to people. The first is that the feces touched a certain part of the pants, and then the hands touched this part of the pants, and then touched the nose or mouth, the person would be infected with the virus.
In the second method, when an infected patient flushes the toilet after going to the toilet, the flushing water generally has a large impact force, and the feces containing the virus may volatilize into the air. If the toilet is closed and the ventilation is not good, and someone is right next to the toilet, they may be infected by breathing.
Beijing News: How much of this transmission method accounts for all transmission methods of the virus?
Zhang Qiwei: No more than half. Many viruses are transmitted through the respiratory tract. Most of the viruses transmitted through feces are enteroviruses, the viruses that cause enteritis. Most respiratory viruses are transmitted through droplets and contact, and the proportion of fecal transmission will not be large.
But it cannot be taken lightly, because if the patient's symptoms are more serious, the amount of virus in his stool will be very large, and once the virus is released into the air during the toilet flush, it will infect more people. Toilets, especially public toilets, can be a very dangerous source of transmission.
Beijing News: How should we respond?
Zhang Qiwei: In the past, I just told everyone to wear masks, wash hands frequently, and disinfect tables, beds, and chairs. Now, disinfection of toilets and toilets may be on the agenda.
Toilets and toilets used by patients with new coronary pneumonia or suspected patients need to be thoroughly disinfected with disinfectants, and the toilets must be ventilated. If patients are not disinfected after use, public toilets can become a source of transmission. Therefore, the relevant government departments need to do a good job of guidance, disinfect public toilets, and cut off the transmission of feces.
Beijing News: What disinfectant should be used to flush the toilet (toilet), can 84 disinfectant be used?
Zhang Qiwei: Yes. Any disinfectant on the market will do.
