Noro, Polio and Hepatitis A are some of the most common viruses transmitted by food and water. Polio is highly contagious and although most people won’t get any or light symptoms when infected, 5%-10% of infected people get very severe symptoms. The spinal cord and brainstem become inflamed, causing paralysis, brain damage and sometimes even death – yikes!
Hepatitis A affects the liver, but generally has less severe symptoms than its siblings Hepatitis B and C. Hepatitis A often goes by with mild flu like symptoms, but some people are affected by jaundice. This has the eerie effect of turning your skin and the whites of your eyes slightly yellow for a while.
There are many more food- and waterborne viruses and bacteria, all of which come with a mixture of diarrhea, vomiting and other unpleasant symptoms when you get infected.
