A new strain of the virus has emerged in the United Kingdom in recent weeks, leading to the reintroduction of lockdowns in various parts of the country.
"We have staff to go shopping and to the supermarkets for them," Wolves manager Nuno Esperito Santo told Sky Sports.
"We have to avoid any kind of risk because we have a small squad and we have problems with some players out.
"We cannot afford to lose any player, we tell them on a daily basis 'don't relax and try to be more careful'.
"Our kitchen staff puts together a big box of the basic things that we need.
"During the high moment of the pandemic, everybody had it. When the situation improved we said to players 'you are free to go and do your own shopping'.
"But now as the levels are increasing so high, and we have this new mutation that everyone is so worried about, we start putting this together again. It's about protecting ourselves.
"We are privileged as professionals in football, so many people take care of us. It's impossible for [the rest of] society, everybody has to take care of themselves."
Wolves, who are 11th on the Premier League table, host Tottenham Hotspur later on Sunday before a trip to Manchester United on Tuesday.
