Ebola has spread across four West African countries, including, Guinea, Liberia and Sierra Leone. The virus has no cure and the only thing that aid workers can do is provide hydration and hope for the best.
The only airport in Sierra Leone with direct flights to London is screening patients for ebola before they enter the airport. Passengers are also required to wash their hands in chlorinated water.
Some of the symptoms of ebola are not unlike other flu viruses. Two days to three weeks after infection patients will have fever, sore throat, muscle pain and headaches. However, as the severity increases patients may feel nauseous, and experience vomiting, diarrhea, decreased function of the liver and kidneys and even internal bleeding.
Even though the ebola virus can be deadly, it’s spreading is not the most severe. Ebola only spreads through close contact. So far, only two foreign aid workers have been infected with the virus. Even once individuals are infected they generally aren’t contagious until they are sick.
According to the World Health Organization, the current ebola outbreak has a survival rate of 40%.
Despite a severe outbreak in West Africa, it’s unlikely to reproduce itself in the developed world. The crisis is so bad overseas because the virus took hold in countries with poor health infrastructure.
