Doctors in protective gear work on March 31, 2014 inside the medical humanitarian group Medecins Sans Frontieres (Doctors without Borders) isolation ward in the southern Guinean town of Gueckedou. Aid organisation Doctors Without Borders said on March 31 an Ebola outbreak suspected of killing dozens in Guinea was an "unprecedented epidemic" as Liberia confirmed its first cases of the deadly contagion. Guinea's health ministry this year has reported 122 "suspicious cases" of viral haemorrhagic fever, including 78 deaths, with 22 of the samples taken from patients testing positive for the highly contagious tropical pathogen.
