Bats have"peacefully co-existed" with viruses for a long time and should not be blamed for the Covid-19 pandemic, said infectious diseases expert Wang Linfa.
He said the coronavirus responsible for Covid-19 is one of several viruses that likely originated in bats and were transmitted to humans via intermediate animal hosts. Prof Wang said the coronavirus - officially known as Sars-CoV-2 - is 80 per cent genetically similar to Sars and 96 per cent similar to a known bat coronavirus.
Another major question that researchers are exploring is why Covid-19 causes mild or no symptoms in younger patients. He said a Covid-19 patient he attended to had seen a general practitioner after experiencing mild shortness of breath.Prof Tambyah added that despite not experiencing breathlessness, coughing, sore throat or any other symptoms, the patient continued to test positive and was hospitalised for eight days until she tested negative twice in a row and was discharged.
