Superbug kills man at an extremely fast speed

Once in a while you hear about bacteria or viruses that can kill a person inspite of the best efforts of doctors, and you wonder about how there can be diseases that can kill people like this; and then you remember about hearing of some diseases such as Ebola where the rate of death is more than 80% of those infected, where the disease actually ends because it has killed too many people before the disease could spread to more people. But how many times have you heard of a bug that could kill people in an incredibly short period of time ? Well, read on (link to article):

A flesh-eating superbug claimed the life of a British father just four hours after he was hospitalised with leg pains. The Daily Mail reports Richard Johnson, 54, died from a rare infection known as necrotising fasciitis in November last year.
The infection moved through Mr Johnson's body so quickly that doctors could actually see it spreading up from his leg to his abdomen as they operated, an inquest into his death was told. The rare infection occurs in the deeper layers of skin and is typically caused by many types of bacteria entering an open wound, especially after major surgery. While commonly known as a flesh-eating bug, the bacteria don't actually eat tissue, instead destroying skin and muscle by releasing toxins.

How horrific it must be to know that you have a condition that will not allow you to last through the day, and how horrible it must be for doctors and for family members to know that you are going down, and there is nothing that they can do.
