The World Health Organization said Thursday that the outbreak that has ravaged West Africa could infect 20,000 people before it is over. With over 1,500 deaths recorded so far, the virus is certain to claim more lives. At least 3,000 people are believed to have been infected in the current outbreak, but WHO officials believe that the tally could be much higher.
