The organisation noted that fear has led to a very high level of vigilance and clinical suspicion worldwide, stating that "such a high level of alert further increases the likelihood that any imported case will be quickly detected and properly managed, limiting onward transmission."
On the downside, the WHO observes that the same fear is compromising outbreak control when it causes airlines to refuse to transport personal protective equipment and courier services to refuse to transport properly and securely packaged patient samples to a WHO-approved laboratory.
Facts about Ebola
- The Ebola virus is highly contagious, but is not airborne.
- Transmission requires close contact with the bodily fluids of an infected person, as can occur during health-care procedures, home care, or traditional burial practices.
- The incubation period ranges from two to 21 days, but patients become contagious only after the onset of symptoms. As symptoms worsen, the ability to transmit the virus increases. As a result, patients are usually most likely to infect others at a severe stage of the disease, when they are visibly, and physically, too ill to travel.
- There is no cure.
- Early detection and supportive care greatly improve prospects for survival.
