In simple words: Polio is a contagious disease caused by a virus. Most people don't have symptoms, but some get flu-like symptoms.In rare cases, it can cause paralysis.

Acute poliomyelitis is a highly contagious viral disease that affects the nervous system, caused by the poliovirus.The virus is typically transmitted through the fecal-oral route. Most infections are asymptomatic, but some individuals may experience mild symptoms like sore throat and fever.In rare cases, the virus can invade the central nervous system, leading to paralysis, which can be permanent.

Example 1: A 4-year-old child presents with fever, headache, stiff neck, and muscle weakness.After laboratory testing and physical examination, the diagnosis of acute poliomyelitis is confirmed., An unvaccinated adult who recently traveled to a region where polio is endemic develops fever, sore throat, and muscle pain, subsequently progressing to paralysis.Stool sample analysis confirms poliovirus infection., A patient experiences mild flu-like symptoms which resolve within a few days.Later, during routine screening, they are found to have antibodies to poliovirus, indicating a prior asymptomatic infection.

Documentation should include symptoms, travel history, vaccination status, physical examination findings (including neurological assessment), and laboratory results confirming the presence of poliovirus or antibodies to the virus.
