Poliomyelitis (polio) is a highly infectious viral disease that largely affects children under 5 years of age. The virus is transmitted by person-to-person spread mainly through the faecal-oral route or, less frequently, by a common vehicle (e.g. contaminated water or food) and multiplies in the intestine, from where it can invade the nervous system and cause paralysis.
Poliomyelitis. Polio (poliomyelitis) mainly affects children under 5 years of age. One in 200 infections leads to irreversible paralysis. Among those paralysed, 5–10% die when their breathing muscles become immobilized. Cases due to wild poliovirus have decreased by over 99% since 1988, from an estimated 350 000 cases in more than 125 endemic ...
Polio does still exist, although polio cases have decreased by over 99% since 1988, from an estimated more than 350 000 cases to 22 reported cases in 2017. This reduction is the result of the global effort to eradicate the disease. Today, only 2 countries in the world have never stopped transmission of polio (Pakistan and Afghanistan).
Oral polio vaccine (OPV) contains an attenuated (weakened) vaccine-virus, activating an immune response in the body. When a child is immunized with OPV, the weakened vaccine-virus replicates in the intestine for a limited period, thereby developing immunity by building up antibodies. During this time, the vaccine-virus is also excreted.
Vitamin A is essential for the functioning of the immune system and the healthy growth and development of children, and is usually acquired through a healthy diet. Yet, vitamin A deficiency is the leading cause of preventable childhood blindness and increases the risk of death from common childhood infections, such as measles and those causing ...
