What is the primary transmission route of poliovirus?

Explanation:
Poliovirus primarily spreads through the fecal-oral route. Infected people shed the virus in their feces, and it can contaminate water, food, hands, and surfaces. When someone ingests this contaminated material, the virus enters the gastrointestinal tract, where it can replicate and sometimes spread to the bloodstream and nervous system. This mode of transmission is especially common in areas with poor sanitation, where contaminated water and food facilitate spread. Other routes like airborne droplets, bloodborne, or direct skin contact are not the main pathways for poliovirus transmission.
