Deeney has become frustrated with people who have defied the instructions from British PM Boris Johnson, which have asked people not to leave their homes unless they are buying essentials, exercising or fulfilling a role as a key worker.
"We've all got to stay at home and follow the government guidelines," Deeney told Watford's official website.
"How many more warnings do we need? They said they will pay 80 per cent of wages and people are still going to work.
"Some are seeing it as a bit of a jolly-up and it is a shame because it could affect so many. You have got to hope people see the curve in Italy and Spain and get (the severity) of it.
"The worst thing that happened was when it came out that it doesn't affect the young so they are like, 'I don't care'."
