The World Health Organization has called for an urgent meeting of 11 countries in Ghana in early July to discuss the best way of tackling the ebola crisis in West Africa, where the deadly disease was described this week as “out of control,” according to a Newsy video.

WHO is urging drastic collective action, as well as the need to develop a comprehensive inter-country operational response plan.

CNN reports that relief workers on the ground said the epidemic has hit unprecedented proportions.

There have been at least 390 deaths and 600 cases in Guinea, Sierra Leone and Liberia since the epidemic began in March, according to WHO’s latest figures released Thursday.

These countries have major medical infrastructure challenges and there is mistrust among communities there of the help that has been sent. In Sierra Leone and Guinea, WHO has said that community members have thrown stones at health care workers trying to investigate the outbreak, CNN reports.

Ebola outbreaks usually are confined to remote areas, making the disease easier to contain. But this outbreak is different; patients have been identified in 60 locations in Guinea, Sierra Leone and Liberia.

People are traveling without realizing they’re carrying the deadly virus, CNN reports. It can take two-to-21 days after exposure for someone to feel sick.

At first, symptoms mimic the flu: headache, fever, fatigue. What comes next is like something out of a horror movie: significant diarrhea and vomiting, while the virus shuts down the blood’s ability to clot. Patients often suffer internal and external hemorrhaging. Many die in an average of 10 days.

Doctors Without Borders, also known as Médecins Sans Frontières, has worked to fight the epidemic since March, sending more than 300 staff members and 40 tons of equipment and supplies to the region to help fight the epidemic.

It’s not enough.

“Despite the human resources and equipment deployed by MSF in the three affected countries, we are no longer able to send teams to the new outbreak sites,” Médecins Sans Frontières reported.

Ebola doesn’t spread as easily as one may think. Patients aren’t contagious until they are already showing symptoms.

There is no cure or vaccine to treat ebola, but it doesn’t have to be a death sentence if it’s treated early, Médecins Sans Frontières said. Ebola typically kills 90 percent of patients, according to CNN. In the current outbreak, the death rate has dropped to about 60 percent.
