5. Polio
Here’s one the majority of us probably devote little thought to these days since it’s been all but eradicated. Polio, however, is still out there and struck 37 people worldwide during 2016. Polio is famous for the muscle paralysis it can cause and it can easily confine victims to wheelchairs or a life of using crutches to get around. In some cases, the disease affects the muscles responsible for breathing and that can end in death. Polio has always been a disease that is most dangerous for children.
