Ebola may start flaring up again in West Africa as a country previously rid of the virus is facing new cases.
A Liberian official announced a second confirmed case of Ebola Wednesday, but declined to specify who or how it was contracted, according to a report from Reuters.
It is unknown whether the case is linked to a confirmed case of a 17-year-old boy who died Sunday of the virus.
In May, Liberia was deemed Ebola free from public health organizations after no new cases surfaced in more than 40 days.
Liberia, along with Sierra Leone and Guinea, is one of the countries hit hardest by the virus that has killed more than 11,000 people.
All of those countries have started to see new cases recently, said Liberian Deputy Health Minister Tolbert Nyenswah in a statement Monday.
To make matters worse is the region's rainy season has started. Public health experts have said the rainy season could make it more difficult to access patients struck by the virus as the rain can make rural roads often inaccessible.
