A come back is being made in our hospitals, Its the reintroduction of Super-bugs. These super-bugs are drug resistant bugs that have become more powerful than any of the medicines known to fight them.
With all the hands sanitizers and sanitizing soaps, sprays and all the thousands of other products currently available. Scientists have discovered that we are being too clean for our own good. Then the super-bugs can attack us and even when we're recovering in a hospital.
Some doctors have advised not to constantly use hand sanitizers but a regular soap in every day hand washing. That will help you in the long run because we need some good bacterial to help our anti-bodies be strong in our bodies.
