China Is Now Requiring COVID-19 Tests Taken by Anal Swab
The government’s rationale for the latest testing regimen is that there is data suggesting that patients recovering from the virus will sometimes test negative with a traditional nasal or throat swab but continue to test positive days later in samples taken from the lower digestive tract. “As for how the test is conducted, the Chinese Center for Disease Control and Prevention published instructions last March,” the Washington Post reports. “It said that a stool sample should be taken from patients, and if that is not possible, to do an anal swab by inserting a cotton-tipped stick three to five centimeters (one to two inches) into the rectum.”
The Chinese government has recently reimposed more stringent coronavirus restrictions as it battles to contain outbreaks ahead of the Lunar New Year next month, a holiday period when huge swaths of the country travel home. So far the anal swab has reportedly only been used in particularly high-risk situations. “Officials took anal swabs from residents of neighborhoods with confirmed Covid-19 cases in Beijing last week, according to the state broadcaster CCTV, while those in designated quarantine facilities have also had the tests,” Agence France-Presse reports.
