PCR positive COVID-19 patients were recruited by consecutive sampling until required sample size of 333 was fulfilled. They were contacted over the phone six weeks after the discharge. Interviewer administered questionnaire was used to evaluate the presence of symptoms of myalgia and arthralgia. Those with positive symptoms were invited for a consultation to conduct further investigations. RESULTS: Of the 333 patients, 96 (28.8%) had persistent arthralgia, myalgia or both, six weeks after recovery from COVID-19. Among them, 56.3% had only arthralgia, 10% had only myalgia and 33% had both myalgia and arthralgia. Two patients (4.8%; 95% CI: 0.6-16.2%) were confirmed of having RA.
