With death toll continuously rising, David Beckham has decided to join the fight against Ebola. Like all volunteers, the 39-year-old celebrity believes that the deadly disease ravaging Sierra Leone can be prevented if everyone exerts some effort.

The Unicef Goodwill Ambassador voiced out his belief in a video: "Six years ago, I travelled to Sierra Leone with Unicef. I was inspired and honoured to have met so many amazing people and to see the beautiful country."

"While there I was lucky enough to get a glimpse into the lives of children in remote villages and the challenges they faced in a country then devastated by civil war," he explained.

He encouraged everyone to start moving: "Today, the courageous people of Sierra Leone are facing an invisible enemy - a ferocious Ebola disease that's spreading fast across West Africa. The good news is that this disease can be avoided if you take the correct measures ... together we can collectively halt this disease in its tracks. Let's start now."

The father of four also described Ebola's effects as "heart-wrenching." As a father, he says it is unimaginable for a child to suffer and feel helpless.

"Unicef is on the ground, working around the clock to protect children and families from this deadly virus. Please give Unicef the help it needs to tackle this crisis. We're in a race against time," he ended.
