Question

sources of polio virus
​

Answer 1

Answer:

Polio (full name: poliomyelitis) is an infectious disease caused by the poliovirus. It is transmitted through contact with an infected person primarily through the fecal-oral route. The virus enters the body through the mouth or respiratory system and multiplies in the throat and intestines. It can travel through the blood and may enter the central nervous system (spinal cord and brain), causing muscle weakness, paralysis, and in some cases, even death. The virus exits the body through the feces (stool).
