A garda from Balbriggan in Dublin he is "lucky" to have recovered from the coronavirus and return home after being critically ill in Beaumont hospital.
Sgt Paul Cullen, a 48-year-old father-of-three, told RTÉ's News At One he thought he had a chest infection when he went to his GP in early April suffering from shortness of breath and high temperatures.
He started antibiotics but the illness escalated, he said, adding it "got worse and worse". He contacted his GP again and ended up being sent by ambulance to hospital.
Sgt Cullen said: "At that stage I couldn't have a conversation." Sgt Cullen was tested for Covid-19 and the infection was confirmed after about 24 hours.
