Is the Ebola virus as dangerous as before?

Untreated Ebola disease has a high mortality rate: on average, half of the infected people die.In previous outbreaks, the mortality rate ranged from 25% to 90%.

However, the WHO stated that it is now more adequately prepared than it was in 2013.

The Global Alliance for Vaccines and Immunization (Gavi) stated in January that there are now two vaccines against the Ebola virus, and 1 vaccines are urgently stocked worldwide to quickly respond to future outbreaks.

BBC Africa editor Mary Harper said that the WHO and the countries themselves have learned lessons from previous outbreaks: “They are very good at tracking and isolating close contacts, so they are better prepared now than before. "

But she pointed out that epidemics often occur in remote areas with poor infrastructure: "These are challenging environments." Harper said, "Even if Africa is not particularly affected by the new crown pandemic, it is now at the same time. Facing the new wave of Ebola virus."
