2. Polio and Related Diseases
Polio once stalked the world and killed or maimed innumerable adults and children. Thanks to an effective vaccine, polio is only found in countries like Afghanistan, Nigeria, Pakistan, Papua New Guinea, and Somalia.
Hand, foot, and mouth disease (HFMD) and Enterovirus 68 (EV-D68) are related to polio. Both are found worldwide. HFMD causes mouth sores and skin rash. It is painful but not deadly.
EV-D68 acts like polio. Most people have a stomach “flu,” some need hospitalization, and some develop paralysis and die.
