POLIOMYELITIS: A VACCINE PREVENTABLE DISEASE

Polio, short for poliomyelitis, is a viral disease caused by the polio virus, primarily affecting children under the age of five. While many infected individuals may experience mild symptoms or remain asymptomatic, in severe cases, polio can lead to paralysis, muscle weakness, even death. The disease is transmitted primarily through the fecal-oral route, often spreading through contaminated food, water or hands.

The history of polio is marked by devastating epidemics that plagued communities around the world. However, the development of effective vaccines by Jonas Salk and Albert Sabin in the mid-20th century revolutionized the fight against poliomyelitis. These vaccines, administered either orally (OPV) or via injection (IPV), have played crucial roles in reducing polio incidence globally.

Despite significant progress in reducing polio cases, the disease remains a public health concern in certain regions. Challenges such as vaccine hesitancy, conflict zones and logistical difficulties have hindered eradication efforts. Vaccine hesitancy, fueled by misinformation and mistrust, has led to reluctance or refusal to vaccinate children against poliomyelitis infection in some communities. Conflict zones and political instability in certain regions have made it difficult to reach vulnerable populations with vaccination campaigns and surveillance activities. Additionally, logistical challenges, including reaching remote or marginalized populations and maintaining the cold chain for vaccine storage and transportation, have posed obstacles to effective polio control.

In response to these challenges, the Global Polio Eradication Initiative (GPEI) was launched in 1988, representing a historic collaboration aimed at eradicating poliomyelitis worldwide. Led by organizations such as the World Health Organization (WHO), United Nations International Children Education Fund(UNICEF), Rotary International and the Centers for Disease Control and Prevention (CDC), the GPEI has made significant strides in reducing polio cases and interrupting transmission. Through mass vaccination campaigns, routine immunization programs, surveillance activities and innovative strategies, the GPEI has brought the world closer to the goal of poliomyelitis eradication.

Despite some challenges, numerous successes and milestones have been achieved in the fight against polio. The near elimination of wild polio virus in many regions, the introduction of innovative vaccination strategies and the development of new tools and technologies for surveillance and response are among the successes of the eradication initiative. Global partnerships, political commitment and community engagement have been instrumental in driving progress and sustaining momentum in the fight against poliomyelitis.
