The 36-year-old nearly died in 2016 after contracting a rare form of the disease in Rio de Janeiro covering the Olympics.
But Charlie is determined not to let concerns that her kidneys may fail in the future get her down.
She said: “About a year ago I got bad results for my kidneys and my liver. I was so frustrated and angry. And salt makes me swell up. But I didn’t survive just to sit here worrying.”
Charlie is backing the campaign Malaria Must Die, So Millions Can Live.
She added: “If we want to have a positive impact on this world, we need to include malaria into the conversation of education and gender equality.”
