Pharmacists or doctors can recommend the appropriate medicine based on the cause of the cough, its duration and other clinical signs such as fever or muscle ache, said community pharmacist Shawn Lee. If the cough is leading to sleeplessness or discomfort, cough medication can help to relieve the symptom. Physiotherapist Jaclyn Chow said that inflammation in the cells infected by the SARS-CoV-2 virus can persist even after one tests negative, leading to lingering symptoms like a cough, airway sensitivity and discomfort in the upper respiratory tract. Previously termed “long COVID”, the condition has recently been renamed post-acute sequelae of SARS-CoV-2 Infection (PASC).ĬNA asked some medical professionals how people can manage such post-COVID symptoms: COUGH AND WHEEZING He added that data suggests these symptoms may be reduced in those who were vaccinated. And 11.7 per cent reported symptoms six months after contracting the virus, said Dr Edgar Tay, a cardiologist at the Asian Heart & Vascular Centre, Mount Elizabeth Hospital. ![]() Local data from the National Centre for Infectious Diseases (NCID) last year showed that 16.9 per cent of a group of COVID-19 patients – who were unvaccinated – reported persistent symptoms at 30 days post-infection.

More false negatives than false positives "They’re not going to go off into a locker room and infect 15 of their teammates," added Mina, a former Harvard University epidemiologist who was not involved in the new study. Michael Mina, the chief science officer for the at-home testing company eMed, said people who are negative on a rapid test might still be mildly infectious, but "they’re not going to be super-spreaders." Sheldon Campbell, an associate professor of laboratory medicine at the Yale School of Medicine who wasn't involved in the research.ĭr. "Only the people shedding the most virus are going to be positive with a rapid test, but those are the people you especially want to identify because they’re the most infectious," said Dr. But Hwang and two other disease experts said rapid tests (also known as antigen tests) are good indicators of when a person might be contagious.
