The death is being investigated by experts under the national committee on communicable diseases, Dr Suwannachai said. The man had not had any other underlying diseases, Dr Thiravat posted on his Facebook page on Sunday. Meanwhile, doctors have detected no virus after testing a male bus driver who suffered severe flu symptoms for about a week, Dr Suwannachai said. Sunday was the first day that new state measures against Covid-19 disease, now listed as a dangerous communicable disease, took effect. This explains why tests on fluids taken from noses and throats often turn out negative, Dr Thiravat said.
