8 Horrible Infectious Diseases Humanity Has Triumphed Over

Tetanus

Tetanus, also known as lockjaw, is an infectious disease that affects your muscles, causing spasms. The symptoms occur in the jaw and then progress to the rest of your body. In general, they last a few minutes and can be extremely severe. Some people even suffered bone fractures because of the spasms. In some cases, tetanus can be fatal. 

The infectious bacteria called Clostridium tetani enters your body through an open wound and then release a toxic substance that usually causes paralysis and spasms. According to researchers, tetanus can’t be eradicated, but you can prevent it through vaccination. 

Statistics show that in 1990 more than 315,000 people died from this disease, but due to vaccination, the mortality rate dropped significantly in 2017 and only 30,000 deaths were reported.
