The devastated family of a Perth grandfather who died suddenly from coronavirus is warning people to "take this virus seriously".
Ray Daniels, 73, had showed no significant signs of being unwell until he collapsed at home on Wednesday and died less than 48 hours later from coronavirus.
"He was a very fit, healthy and active man, with no known underlying health issues," the family said in a statement on Friday.
"Clearly this virus does not discriminate and we never believed for one second that it would take him from us.
"Everybody needs to take this virus seriously and follow the health advice that is being given."
The family also thanked the paramedics and hospital staff at Joondalup Health Campus who "tried everything to save his life".
Mr Daniels, who is the father of a serving WA police officer, recently travelled on a cruise ship.
Health Minister Roger Cook said Mr Daniels' death was a "salient message and lesson for us all".
"This disease is insidious. In some people, they present to be almost asymptomatic before they decline rapidly," he told reporters.
Mr Daniels became the second person to die in WA from COVID-19 following the death of 78-year-old James Kwan.
