The former Girls Aloud singer said at one stage doctors had given her just 24 hours to live.Cole was struck down by the illness - which is spread by mosquitoes - during a holiday in Tanzania, just a year after she climbed Mount Kilimanjaro for Comic Relief to help with malaria efforts.She will now address Sport Relief viewers on Friday in a bid to encourage them to donate money to help efforts against the disease, paying for medical supplies and mosquito nets.She said: "When I climbed Kilimanjaro for Comic Relief five years ago it was honestly one of the hardest things I've ever done."The motivation lay in knowing it could help in eradicating malaria and ultimately saving lives by providing mosquito nets."I didn't for one minute think that only a year later I would get malaria myself and become so ill that at one point I was given 24 hours to live."It was the scariest thing you could ever imagine for me and for my friends and family."The pain I felt and went through, it's what so many people go through, all because they don't have a mosquito net which could save their life."I was lucky; I had the best care I could get. Some people are not so lucky. A £5 mosquito net could keep a child safe and really does help."
