Yellow fever



Key facts

This disease affects mainly children under five years of age. One out of 200 cases of the disease lead to terminal paralysis. Between 5% and 10% of those affected suffer from paralysis because their respiratory muscles stop functioning. It is estimated that polio cases have fallen by 99% since 1988, from about 350,000 cases registered in that year to 33 * cases reported in 2018. This decrease is the result of efforts being made globally to eradicate the disease. If there is one child with polio virus infection, children in all countries are at risk of contracting the disease. Failure to eradicate polio from these outbreak strongholds may result in the infection of about 200,000 new cases worldwide in ten years.In most countries, global polio eradication efforts have made room for increased resilience to other communicable diseases by building effective systems in surveillance and immunization.Polio and its symptoms. Polio is a highly contagious viral disease that invades the nervous system and can cause complete paralysis within hours of time. The virus is transmitted by spreading from person to person mainly through faces, and to a lesser extent through a common medium (such as contaminated water or food) and it multiplies in the intestine. The primary symptoms of the disease are fever, fatigue, headache, vomiting, stiff neck and pain in the extremities. One in 200 cases of the disease leads to terminal paralysis (usually affecting the legs). Between 5% and 10% of those with paralysis die because their respiratory muscles no longer function. The most vulnerable groups are at risk. This disease mainly affects children under the age of five. Disease prevention There is no cure for polio, but it can only be prevented. A polio vaccine, given in multiple batches, can protect a child from the evil of life for life. The global burden of cases Since 1988, the number of polio cases has decreased by more than 99%, as it is estimated that this number has decreased from about 350,000 cases that were registered in more than 125 countries endemic to the disease at the time to 33 cases reported in 2018.Of the three wild poliovirus strains (type 1, type 2 and type 3), type 2 wild poliovirus was eradicated in 1999, and the number of cases of wild poliovirus 3 has decreased to its lowest levels in history.
