Venezuela reports first case of polio since 1989

The video explains how a virus enters the body through the mouth via contaminated feces or droplets from a cough or sneeze. It multiplies in the small intestine and spreads to the central nervous system, destroying motor neuron cells. Most infected individuals do not get sick, but some develop nonparalytic polio with flu-like symptoms. Paralytic polio, though rare, can cause muscle pain, paralysis, and even death. Young children, especially those who are malnourished and unvaccinated, are particularly vulnerable. While there is no cure for polio, it is preventable through immunization.
