Ebola returns to Liberia

Six new cases of ebola were discovered in Liberia in June, more than a month after it had been declared ebola-free. More than 100 people were under observation after a 17-year-old boy in Margibi County died of ebola and his neighbor tested positive for the disease. A second infected individual died on July 15. Officials had not ruled out an infected animal as the source of the disease in this case.

On July 20, the four survivors were released from the hospital and declared ebola-free.

Ebola still has a presence in Sierra Leone and Guinea, where a total of 86 new cases were diagnosed in July. More than 11,000 people have died from ebola since the current outbreak in West Africa began in March 2014.
