Poliomyelitis,commonly shortened to polio,is an infectious disease caused by the poliovirus. Approximately 75% of cases are asymptomatic;mild symptoms which can occur include sore throat and fever;in a proportion of cases more severe symptoms develop such as headache,neck stiffness,and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis,and possible death in extreme cases. Years after recovery,post-polio syndrome may occur,with a slow development of muscle weakness similar to that which the person had during the initial infection.

Polio eradication,the permanent global cessation of circulation of the poliovirus and hence elimination of the poliomyelitis (polio) it causes,is the aim of a multinational public health effort begun in 1988,led by the World Health Organization (WHO),the United Nations Children's Fund (UNICEF) and the Rotary Foundation. These organizations,along with the U.S. Centers for Disease Control and Prevention (CDC) and The Gates Foundation,have spearheaded the campaign through the Global Polio Eradication Initiative (GPEI). Successful eradication of infectious diseases has been achieved twice before,with smallpox in humans and rinderpest in ruminants.
The eradication of infectious diseases is the reduction of the prevalence of an infectious disease in the global host population to zero.

The 2013–2016 epidemic of Ebola virus disease,centered in Western Africa,was the most widespread outbreak of the disease in history. It caused major loss of life and socioeconomic disruption in the region,mainly in Guinea,Liberia and Sierra Leone. The first cases were recorded in Guinea in December 2013;later,the disease spread to neighbouring Liberia and Sierra Leone,with minor outbreaks occurring in Nigeria and Mali. Secondary infections of medical workers occurred in the United States and Spain. In addition,isolated cases were recorded in Senegal,the United Kingdom and Italy. The number of cases peaked in October 2014 and then began to decline gradually,following the commitment of substantial international resources.
A public health emergency of international concern is a formal declaration by the World Health Organization (WHO) of "an extraordinary event which is determined to constitute a public health risk to other States through the international spread of disease and to potentially require a coordinated international response",formulated when a situation arises that is "serious,sudden,unusual,or unexpected",which "carries implications for public health beyond the affected state's national border" and "may require immediate international action". Under the 2005 International Health Regulations (IHR),states have a legal duty to respond promptly to a PHEIC. The declaration is publicized by an IHR Emergency Committee (EC) of international experts,which was developed following the 2002–2004 SARS outbreak.
