Cat scratch fever is spreading through the NFL and the NFL is doing everything it can to help those affected.

It’s an illness that was caused by a fungus.

The NFL has issued a public health alert saying that there is a 50 percent chance that the illness will continue to spread, and a 30 percent chance it will spread outside of the U.S. While the NFL has offered some financial support, many of its players are taking it upon themselves to make sure their players have a clean house, according to NFL Media Insider Ian Rapoport.

“It’s very important for us to do everything we can to try to keep them safe and to be proactive in cleaning up the situation,” Rapoports reported.

“We’re doing everything we possibly can to keep those people in a clean environment, but if that’s not enough, we have some great charities that have been working on this.”NFL spokesman Greg Aiello confirmed that the NFL Players Association will work with the NFLPA to help players get the best medical care possible, but said the NFL will continue the same approach of “not forcing people to go to the emergency room.”

“The players are responsible for their own health, their own welfare,” Aiella said.

“So we are going to be working with the players to make the best out of that situation and hopefully we can continue to be supportive of them as they continue to heal.”

In the wake of the new-found illness, many players have come forward to share their stories of the disease, including running back Adrian Peterson and linebacker Luke Kuechly.

Peterson told ESPN that he was diagnosed with cat scratch fever on the first day of training camp.

He was sent home after two days, and returned to the practice field after two weeks.

Kuechlin, a former running back, said that he and his teammates had to clean out their houses, clothes, even their car.

“The cat scratch virus that we got from that fungus, the cat scratch is going to make us very ill,” Kuechanly said.

“We don’t know how long it’s going to last, but I would say we’re not going to have a normal offseason.”

It’s not clear if Kuechily will be able to play in the postseason, but Kuechinly said that the cat problem is making him question his future with the Minnesota Vikings.

“This is going into the season, so that’s why I’m thinking about it,” Kuichly said, according the Associated Press.

“I’m not really thinking about this anymore.”

The NFL will be hosting an “emergency meeting” this weekend to discuss the spread of the virus and how to protect players.

The meeting is expected to take place on Sunday at 3 p.m.

ET, with the league saying that it will have more information on how to deal with the new illness on Monday.
