Polio Eradication
Save
Polio eradication is a global public health initiative aimed at eliminating all cases of poliomyelitis, a paralytic disease caused by the poliovirus. The initiative was launched in 1988 by the World Health Organization (WHO) and has since been supported by governments, NGOs, and other organizations around the world.
History of Polio Eradication
Polio was once a common childhood disease, causing paralysis and death in countless individuals. In the 1950s, a vaccine was developed that effectively prevented the disease, and vaccination programs were implemented in many countries.
In 1988, the WHO launched the Global Polio Eradication Initiative (GPEI) with the goal of eradicating polio worldwide by the year 2000. The GPEI has made significant progress towards this goal, with the number of cases of polio decreasing by over 99% since its launch.
Challenges of Polio Eradication
Despite the progress made, polio eradication remains a challenging goal. The poliovirus is highly contagious and can be spread through contact with infected individuals or contaminated objects. Additionally, some countries have low vaccination rates, which can make it difficult to achieve herd immunity.
Other challenges to polio eradication include:
