Which method of transmission is responsible for spreading poliovirus?

The poliovirus is primarily spread through the oral and fecal route. This means that the virus can be transmitted when an individual ingests food or water contaminated with feces from an infected person. This method of transmission is particularly relevant in areas with inadequate sanitation, where the fecal contamination of water sources can lead to outbreaks.

Infected individuals excrete the virus in their stool, which can then contaminate hands, surfaces, and various food items. When other individuals unknowingly ingest the virus through these contaminated means, they become susceptible to infection.

This understanding of transmission is crucial for preventing the spread of poliovirus, emphasizing the importance of hygiene practices and clean water access in controlling the disease's transmission within communities.
