Transmission
how this disease is transmitted
- Polio is very contagious
- The virus is originally caused and transmitted through water, mostly in the summer when people spend a lot of their time swimming, often in “water holes” that were contaminated by sewage water
- Where raw sewage is able to enter the water without being treated first, the polio virus will spread easily.
- All a person has to do is swallow some of this contaminated water and the virus infects the intestinal tract.
- It also spread through human contact, usually among children who don’t wash their hand.
