'

Acute anterior poliomyelitis (AAP), commonly referred to as polio, is an infectious viral disease that affects the nervous system. It is caused by the poliovirus, which is a member of the enterovirus family. The main symptom of the disease is muscle weakness, which can be temporary or permanent.

Poliovirus is transmitted mainly through oral-fecal contact, as it is shed through the feces of infected people for a few weeks. It can also be spread through contaminated water and food, as well as close contact with someone who is infected. It is highly contagious, and while most people who get infected with the virus do not get ill, some may develop the disease, particularly children under the age of 5.

AAP is characterized by sudden onset of muscle pain in the affected area, along with weakness and paralysis of the affected muscles. The paralysis is usually focal and may be mild or severe. Mild paralysis may result in difficulty walking, while severe paralysis may lead to respiratory failure and even death. Treatment of the condition involves supportive care and the administration of antiviral medications.

AAP can be prevented through vaccination. The World Health Organization recommends that all children receive the polio vaccine in order to prevent the spread of the virus. Vaccines for the virus are effective at preventing the disease, but not at curing it. The best way to prevent the spread of polio is by practicing good hygiene and sanitation, as well as avoiding close contact with individuals who are infected.
