‘No proof of significant mutation, increased transmissibility of coronavirus’

In Pakistan, health experts claim that so far no concrete evidence is available if the pathogen responsible for causing Covid-19 has significantly mutated and increased its transmissibility. Dr Faisal Mahmood, an associate professor of infectious diseases at the Aga Khan University, said people should continue taking precautionary measures instead of listening to unproven and unscientific theories. He said viruses definitely mutate, but so far no evidence is available whether it has become more lethal, undetectable or even more infectious than before.
