What is the primary mode of transmission for poliovirus?

Explanation:
Poliovirus is spread primarily through the fecal-oral route. The virus is shed in feces and can contaminate water or food in areas with poor sanitation; when someone ingests that contaminated material, the virus begins replicating in the gut and can spread to other tissues. This fecal-oral transmission is the main way polio spreads in populations. Other routes don’t drive polio transmission. Bloodborne spread isn’t how the virus typically moves from person to person, and airborne droplets aren’t the primary route of transmission for polio. Direct skin contact isn’t a common mode of spread either.
