Chinese researchers have found the 2019 novel coronavirus (2019-nCoV) that is at the center of a growing epidemic in the feces and anus tissue samples of infected patients, which could suggest another way the virus is being transmitted.
A study by Wuhan University Renmin Hospital and the Chinese Academy of Sciences found that nucleic acid tests of those samples came back positive for 2019-nCoV, online news services run by the Chinese News Service reported yesterday.
The finding suggested the virus could possibly be spread through “feces-to-mouth” transmission, in addition to transmission through droplets or direct physical contact, the Chinese News Service report said, citing the study’s results presented at a news briefing in Shenzhen on Saturday.
Chang Ko (張科), head of the infection control division of Kaohsiung Municipal Siaogang Hospital, yesterday said that the Chinese finding was not surprising, given that US researchers had already found 2019-nCoV residue in feces.
A study published in the New England Journal of Medicine on Friday said a stool sample taken from the first person confirmed in the US to have the coronavirus tested positive for the virus, Chang said.
Shih Shin-ru (施信如), head of the Research Center for Emerging Viral Infections at Chang Gung University, said that the new findings suggest preventing the spread of the virus will be more challenging, because there is another way it can be transmitted.
Local experts are advising the public to flush toilets with the lids down and to wash their hands thoroughly after going to the bathroom.
Hwang Kao-pin (黃高彬), director of the division of pediatric infectious diseases at China Medical University in Taichung, said it was not uncommon to find viruses in stool.
However, the fecal transmission path could pose a threat, because if 2019-nCoV-infected stool is splashed by water out of a toilet, the virus it carries could live for two to three hours in the air and up to five days on the surface of an object, Hwang said.
To reduce the risk of infection, toilets should be disinfected with alcohol before they are used and flushed with their lids down, in addition to washing hands with soap after going to the toilet, Hwang added.
A debt dispute between a restaurant owner and a criminal ring might be behind a bizarre cockroach attack at the Taipei eatery on Monday night while it was hosting a police gathering, Taipei Police Commissioner Chen Jia-chang (陳嘉昌) said yesterday. Preliminary findings of a police investigation into the case at the G House Taipei suggest that the unusual incident might have been directed at the restaurant’s owner, who allegedly owes money to the Bamboo Union, Chen said. The suspects were Bamboo Union members and there was no evidence indicating that the cockroaches were targeted at the police officers at the restaurant, he
Taiwan’s armed forces should closely monitor China’s development of a new tanker aircraft, as it would significantly boost the Chinese air force’s capability to carry out long-range raids, a military expert said on Wednesday. Ou Si-fu (歐錫富), a research fellow at the Institute for National Defense and Security Research, said in an online article that China is developing a tanker variant of its Y-20 military transport aircraft, known as the Y-20U. The Y-20 has a maximum take-off weight of 220 tonnes and the tanker variant is expected to carry up to 60 tonnes of fuel, more than three times the maximum
QUARANTINE BLUNDER: The government should be responsible for a cluster infection at a hotel, as the cases have caused panic, DPP Legislator Chen Ming-wen said The Ministry of Transportation and Communications should make it mandatory for pilots and flight attendants, as well as their family members, to be vaccinated in view of a cluster of COVID-19 cases at the Novotel Taipei Taoyuan International Airport hotel, lawmakers said at a meeting of the legislature’s Transportation Committee yesterday. The cluster infection at the hotel had led to 28 confirmed COVID-19 cases as of Tuesday, including hotel workers, as well as China Airlines flight and cabin crew, and their family members. The Central Epidemic Command Center (CECC) yesterday tightened quarantine requirements for pilots and flight attendants, who must quarantine
TRAVELING WHILE CONTAGIOUS: The highest risk of infection is indoors, especially in settings where people take off their masks to eat and drink, an expert warned The Central Epidemic Command Center (CECC) yesterday posted a list of places visited by people who were recently diagnosed with COVID-19 while they were likely contagious, urging people who visited the sites at the same time to practice self-health management. Minister of Health and Welfare Chen Shih-chung (陳時中), who heads the center, said that confirmed case No. 1,129 — a woman in her 60s who works at Novotel Taipei Taoyuan International Airport, a designated quarantine facility, and tested positive on Friday — visited Chiayi between Friday last week and Monday. On the first day of her trip, she visited the Big Chiayi
