The CDC is warning that the virus is likely to spread even more quickly this summer than it did last year in the United States, as Americans become increasingly desperate for answers about how it started.
The CDC also warns that the spread of Ebola is likely only to worsen in coming weeks as Americans return to work and school.
President Donald Trump announced in March that the U.S. would send nearly 2,000 military personnel to Liberia and Sierra Leone to fight the virus.
The U.K. has pledged to send 3,000 soldiers.
The United States has sent 3,300 troops to Liberia.
Ebola cases have been steadily increasing in West Africa over the past few weeks.
The first case was reported at the beginning of July, and since then more than 10,000 people have been infected.
Since then, more than 1,300 cases have occurred, with the U,K., U.N. and European Union saying they have detected the virus in at least 1,100 people.
In Sierra Leone, the number of confirmed cases has risen to nearly 5,000, the highest since December, according to the United Nations Office of the High Commissioner for Refugees.
Despite the spike in the virus, the World Health Organization says the disease is stable in Liberia, with a mortality rate of around 1,000 deaths per 100,000 residents.
The number of deaths is expected to fall in coming months, but experts say it’s likely to remain elevated.
Trump has promised to bring a halt to U.A.E. aid, but he has also suggested that the money could be diverted to other countries.
Some Liberians are now using social media to call for an end to U-Haul.
