Save the Children, a charity that is lending aid to the Ebola stricken countries in West Africa, has renewed the call for global support in the wake of the outbreak’s growing momentum. According to the charity an estimated five new infections are being reported every hour in Sierra Leone, one of the hardest hit areas.

The influx of new cases is completely overwhelming the resources available to treat and contain the illness. Save the Children reports that the entire country of Sierra Leone has 327 hospital beds available, yet last week alone there were 765 new cases reported.

The increasingly overwhelmed resources means that containment efforts are even more challenging. Every time an area is secured, another outbreak springs up in a different area, adding to the strain on facilities and personnel that are already beyond taxed.

To date, 7,178 worldwide cases of Ebola infection have been confirmed, as have the resulting 3,338 deaths. Save the Children reports that both of these numbers are likely much higher, as accurate records are not being kept of the children who are “dying anonymously at home or in the streets.”

The rate of infections has been steadily increasing and has been reported to be doubling every three weeks. With the current rate of five an hour, experts estimate that the rate could go up to 10 an hour by Halloween.

The U.K. has promised to construct new facilities that would add 700 more beds in Sierra Leone, but the construction on these could take weeks to months to complete.

Save the Children is calling for a global aid to significantly step up their response to this health crisis in hopes of preventing countless deaths from a disease that is ravaging the area “like wildfire.”
