Coronavirus tests: which one should you take?
New coronavirus tests are being developed every day. The Trump administration just ordered 150 million rapid antigen tests from Abbott Laboratories, but how do they stack up against other tests like the Polymerase chain reaction (PCR) test? Top infectious disease doctors from Harvard and Johns Hopkins break down the differences between the two tests to determine which diagnostic tool might be better at curbing transmission rates.
COVID-19 may persist in the gut even after the virus has been cleared from the airways — suggesting that fecal matter could be a better way to detect the virus than traditional nose swabs, according to a new study.
The study, which was published in the medical journal GUT, said the virus may continue to infect the digestive tract even if a patient isn’t suffering from any gastrointestinal symptoms.
PROTECTING AGAINST CORONAVIRUS: IS A FACE MASK OR FACE SHIELD BETTER?
Researchers at the Chinese University of Hong Kong said stool samples could be used to detect the virus.
They looked at the stool samples of 15 COVID-19 patients and found active gut viral infections in seven — even without any gastrointestinal symptoms.
Three of them continued to suffer from active gut viral infections for as long as six days after their respiratory samples tested negative for the virus, researchers said.
Researchers said the findings suggest that stool samples may be a better way to detect the virus.
CAN SINGING ‘HAPPY BIRTHDAY’ SPREAD CORONAVIRUS?
Paul Chan, chairman of the university’s Department of Microbiology, noted that children are particularly good candidates for stool samples since their viral load was “many times higher” than that of adults.
“Stool specimens are more convenient, safe and non-invasive to collect in the pediatric population and can give accurate results,” Chan said in a statement.
