New studies have shown that Covid-19 can be transmitted by fecal – oral route and the duration of transmission can be up to 20 days.
A series of new studies on the Covid-19 virus have shown that it is more likely to spread for longer than similar viruses, such as the virus that causes SARS, according to the South China Morning Post.
The researchers found that on average, people with SARS-CoV-2 (Covid-19) can spread the virus for a period of 20 days, causing the pathogen to spread even before the onset of symptoms.
The virus persists in the feces of some children. This suggests that it can be transmitted by fecal – oral route.
According to a study by a team from China-Japan Friendship Hospital, including China National Health Committee Cao Bin expert, the isolation period needs to be extended.
“The 20-day period will ensure the passage of the time a person can spread the virus,” Cao Cao Bin said in an interview with Caixin magazine on March 11.
Researchers estimate that 44% of infections can occur before an infected person develops symptoms. This study shows a greater similarity of Covid-19 and seasonal flu than SARS.
In another paper published by the journal Nature Medicine last week, researchers in Guangzhou studied 10 children between 2 months and 15 years old and found that 8 cases were consistently positive when sampling. in the rectum after a nasal secretion sample is negative.
“This suggests that the gastrointestinal tract may spread the virus and the fecal-oral route is quite possible,” the study said.
