Global health officials declare the need for immediate, drastic action to combat Ebola

The worst Ebola epidemic in history has infected more than 3,069 individuals, claimed 1500 lives, and caused immeasurable panic and fear. With the virus spreading unabated throughout Liberia, Guinea, and Sierra Leone, top global health figures have assumed active roles in beseeching world leaders and medical organizations to provide urgent assistance in combating the epidemic.

Ebola virus infectious diseasesIn a recent conference, Doctors without Borders International President Joanne Liu declared that the “world is losing the battle to contain (the virus),” and she faulted world leaders for their failure to assist the West African governments struggling to manage the outbreaks. Similarly, Centers for Disease Control and Prevention Director Tom Frieden has advocated for the urgent increase in large-scale containment efforts, as the “window of opportunity” to contain the virus is quickly closing.

According to these leaders, several issues have contributed to the expanse of the Ebola epidemic. According to Dr. Liu, fragmented health systems and scant resources have rendered West African health centers ill-equipped to handle the rising number of cases. In several areas of Liberia and Sierra Leone, residents have rioted over the poor living conditions in isolation units, high numbers of medical workers infected with the virus, and presence of infected bodies in town streets.

Dr. Margaret Chan, Director-General of the World Health Organization, has also called for urgent action, and outlined a six-month, $490 million plan that would require thousands of medical providers working on the ground in West Africa to halt the Ebola outbreak. The United States government has also contributed $24.9 million to Mapp Biopharmaceutical Company to fund the production and testing of ZMapp, the experimental treatment that successfully aided the recovery of two Ebola infected Americans.

WHO declares Global Health Emergency concerning recent polio outbreaks in Syria, Pakistan, and Cameroon

According to a recent New York Times article, recent polio outbreaks in Syria, Pakistan, and Cameroon have compelled the World Health Organization to declare a Global Health Emergency, effectively issuing travel restrictions for the three countries and summoning their leaders to augment efforts to control the disease. Though only 68 cases of polio had been reported by April, this number marks a significant escalation for a disease thought to be nearly eradicated after 25-year international vaccination campaigns. Furthermore, only 1 of 200 polio cases exhibit symptoms, implying that the number of polio carriers has increased even more drastically. Scientists have yet to discover a cure for polio, and the disease can inflict paralysis and death among hosts, particularly among children.

A key consequence of the Global Health Emergency declaration, the travel restrictions reflect an increased severity in the tone of regulatory functions of the World Health Organization. By the time of the declaration, polio had already spread from the three countries to Afghanistan, Iraq, and Equatorial Guinea, and the WHO fears the disease may spread to other nations such as South Sudan or Ukraine, whose current civil conflicts would hinder vaccination campaigns. While the WHO lacks the authority to implement those restrictions, other countries likely will ban travel to the affected countries and reject entries from Syrian, Pakistani, or Cameroonian citizens.

While polio has largely disappeared throughout the world, the disease still threatens resurgence in some nations where civil conflict or political disorganization obstructs the implementation of effective vaccination campaigns. Organizing these campaigns poses logistical challenges such as the recruitment, training, and payment of hundreds of vaccinators, as well as complex delivery strategies such as door-to-door home visits in rural or dangerous areas. Vaccination teams in Nigeria and Syria have also been the target of attacks from Islamic terrorist groups.   More>>>
