Typically, Covid-19 patients with mild-to-moderate symptoms recover after 2 to 6 weeks. While most patients recover from Covid and return to normal health, there are some patients that present with symptoms that can last for weeks or even months afterwards. This persistent state of ill health is known as ‘Long Covid’ or Post-Covid Syndrome. But how many covid-19 survivors here suffer from the effects of the disease? Melisa Idris and Sharaad Kuttan speak to Professor Dr Moy Foong Ming, Centre of Epidemiology & Evidence-Based Practice, Faculty of Medicine, Universiti Malaya.
