The first Argentina death had travelled to Paris which has not previously been mentioned much as a source.
According to hospital sources, the virus was detected once the patient had died. He had been hospitalized for more than five days and had other health complications: he suffered from diabetes, hypertension, chronic bronchitis and kidney failure.
Seemed like a pretty ill man already so good the hospital did proper investigations but he has likely infected several health care workers before he died.
It's like Italy, Washington State, Milton Keynes repeating itself once more in that missed cases are in hospital potentially passing it on before being diagnosed. This virus is a bastard.
