World Polio Day – 24 October

World Polio Day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine against poliomyelitis. Use of this inactivated polio virus vaccine and subsequent widespread use of the oral polio virus, developed by Albert Sabin, led to the establishment of the Global Polio Eradication Initiative (GPEI) in 1988. As of 2013, GPEI had reduced polio worldwide by 99%.

Polio is a crippling and potentially fatal infectious disease. There is no cure, but there are safe and effective vaccines. Polio can be prevented through immunization. Polio vaccine, given multiple times, almost always protects a child for life. The strategy to eradicate polio is therefore based on preventing infection by immunizing every child until transmission stops and the world is polio-free.

World Tuberculosis Day – 24 March

March 24 commemorates the day in 1882 when Dr Robert Koch astounded the scientific community by announcing to a small group of scientists at the University of Berlin’s Institute of Hygiene that he had discovered the cause of tuberculosis, the TB bacillus.

According to Koch’s colleague, Paul Ehrlich, “At this memorable session, Koch appeared before the public with an announcement which marked a turning-point in the story of a virulent human infectious disease. In clear, simple words Koch explained the aetiology of tuberculosis with convincing force, presenting many of his microscope slides and other pieces of evidence.”

At the time of Koch’s announcement in Berlin, TB was raging through Europe and the Americas, causing the death of one out of every seven people. Koch’s discovery opened the way toward diagnosing and curing tuberculosis.
