The quarantine is over for 51 people in Texas who were exposed to an Ebola patient. Meanwhile the two healthcare workers who got the virus while treating Thomas Eric Duncan, are still struggling to recover in specialized treatment centers. But the epidemic is still raging in West Africa. So far it’s claimed the lives of more than 4,500 people. And the race is on to find a vaccine or treatment for the deadly virus.
