Watford defender Adrian Mariappa is one of the three Hornets staff to have tested positive for coronavirus but insists he has no idea how he caught it.
The 33-year-old was one of six positive results from the first round of Premier League testing this week as the top flight takes steps towards a resumption. Along with two other members of Watford staff, Burnley assistant manager Ian Woan also tested positive.
Mariappa said: "Ever since I got my positive result back on Tuesday, I've been scratching my head to try to work out how I might have got coronavirus.
"It was a big surprise because I haven't really left the house, apart from some exercise and the odd walk with the kids. I've mainly just been homeschooling and keeping fit. The club doctor called to tell me and, to be honest, I did ask whether it could be 100 per cent accurate or whether my results could have got muddled up. Maybe if I had been displaying any symptoms then it might have made sense. But in my head it wasn't adding up.
"I've not had any symptoms and I've felt as fit as ever, probably fitter because I've been working really hard. I've been following my training programme and I've not felt out of breath or ill, or anything.
"We've been fully monitored the whole time and the club have been able to track our distances and things.
"I've been really excelling in all of that. It's quite scary how you can feel absolutely fine and not really have left the house, and yet still get the virus."
The Jamaica international added: "If it wasn't for the fact I had gone back to training and had this test, then I'd never have found out that I had the virus and I would just be getting on with things as normal. That's obviously quite a strange thought."
