RED ALERT! EBOLA Outbreak Sweeping Across Africa

The World Health Organization says "drastic action is needed" to stop the deadly Ebola virus outbreak in West Africa. It has sent teams of experts to help locals deal with the epidemic and WHO plans to meet next week to discuss how to contain it.

Relief workers on the ground said the epidemic has hit unprecedented proportions.

"The epidemic is out of control," said Dr. Bart Janssens, director of operations for Doctors Without Borders.

There have been at least 600 cases and 390 deaths in Guinea, Sierra Leone and Liberia, according to a WHO statement released Thursday. That's since the epidemic began in March, according to the latest World Health Organization figures.

Complicating matters, these countries have major medical infrastructure challenges and there is a real sense of mistrust from 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.
