La febbre emorragica, che continua a propagarsi a livello geografico, ha provocato finora la morte di 4'447 persone su un totale di 8'914 casi registrati dall'inizio dell'epidemia, lo scorso mese di marzo. Un tasso di mortalità che sfiora il 50%, ma che potrebbe raggiungere anche il 70% e per il quale non si è ancora trovato un rimedio.
L'Organizzazione mondiale della sanità prevede che il numero dei malati di ebola è destinato a superare quota 9'000 entro la settimana. Martedì, l'agenzia dell'Onu per la salute ha inoltre dichiarato che il ritmo dei contagi nei paesi più colpiti - Sierra Leone, Guinea e Liberia - è leggermente rallentato, ma che ha raggiunto "altri settori" che, fin a un mese fa, erano stati risparmiati.
