According to the World Health Organization, the number of Ebola cases has reached 2,240 with 1,229 deaths. The disease has spread to Nigeria, Liberia and Sierre Leone. There are currently reports of various incidents of social unrest due to the disease, including a report that 17 patients have fled a clinic in the Liberian capital of Monrovia after gunmen broke in, claiming that the disease was a Western hoax. Definitive diagnosis of the disease remains complicated because of the conditions in the countries involved because of the conditions on the ground.
There have been no confirmed cases of Ebola outside of West Africa.
Meanwhile, WHO released the following statement,"The scale, duration, and lethality of the Ebola outbreak have generated a high level of public fear and anxiety, which extends well beyond west Africa. Such reactions are understandable, given the high fatality rate and the absence of a vaccine or cure.
Recent intense media coverage of experimental medicines and vaccines is creating some unrealistic expectations, especially in an emotional climate of intense fear. The public needs to understand that these medical products are under investigation. They have not yet been tested in humans and are not approved by regulatory authorities, beyond use for compassionate care.
Evidence of their effectiveness is suggestive, but not based on solid scientific data from clinical trials. Safety is also unknown, raising the possibility of adverse side effects when administered to humans. For most, administration is difficult and demanding. Safe administration of some requires facilities for intensive care, which are rare in west Africa.
WHO has advised that the use of experimental medicines and vaccines under the exceptional circumstances of this outbreak is ethically acceptable. However, existing supplies of all experimental medicines are either extremely limited or exhausted.
While many efforts are under way to accelerate production, supplies will not be augmented for several months to come. Even then, supplies will be too small to have a significant impact on the outbreak.
WHO welcomes the decision by the Canadian government to donate several hundred doses of an experimental vaccine to support the outbreak response. A fully tested and licensed vaccine is not expected before 2015.
Another source of public misunderstanding, especially in affected areas, comes from rumours on social media claiming that certain products or practices can prevent or cure Ebola virus disease.
Decades of scientific research have failed to find a curative or preventive agent of proven safety and effectiveness in humans, though a number of promising products are currently under development.
All rumours of any other effective products or practices are false. Their use can be dangerous. In Nigeria, for example, at least two people have died after drinking salt water, rumoured to be protective.
The most effective personal behaviours are avoiding well-known high-risk situations, knowing the symptoms of infection, and reporting early for testing and care. Evidence suggests that early supportive care improves the prospects of survival.
The Ebola virus is highly contagious but only under very specific conditions involving close contact with the bodily fluids of an infected person or corpse. Most infections have been linked to traditional funeral practices or the unprotected care, in homes or health facilities, of an infected person showing symptoms.
Apart from these specific opportunities for exposure to the virus, the general public is not at high risk of infection."
