what got rid of the plague?

Question

i know i'm asking too many questions about the plague but i can't really find an answer to this question. if any one can help me, i'd love that.

Answer 1

There has been several plague outbreaks in the history of man.
---------
In 1898, Paul Louis Simmond proved that Y. pestis was spread by fleas, but his work was initially met with ridicule. It was not until a British commission confirmed this in 1908 that it became accepted. Attempts were made to disinfect the sewers of major cities using carbolic acid, but this only succeeded in driving out the rats that lived there, thus leading to more cases of plague infections.

After you read this website that I am sending you, it will be apparent that the control of rats , discovery of antibiotics , better isolation of plague victims, and sanitation controlled the plague.

Nobody will say it has been rid off, only that outbreaks have been controlled.

Answer 2

Better hygene was one factor.... Cities across Europe began to implement ways to bring clear water into cities and devise ways for waste and sewage to be taken *far* away from the same cities.. No more throwing junk out 2nd story windows etc. into the street below.

On a plus side, the Black plague appears to have left some current day Europeans immune to HIV/AIDS..... 10% of Europeans, 5% of Hispanics, 2% of Africans to be accurate..... All because of a mutation created during the Black plague.

Answer 3

One answer is that viruses "burn" themselves out as they reproduce. The Marvo virus is a good example. Think of it as a colony that spreads so rapidly that some of its gene structure is lost in millions of translations. Eventually the virus can no longer cause the original damage to the host cells that overwhelm the system and the host is no longer a good incubator for that strain. This doesn't mean it can't be "reactivated" as a virus reinvents itself to become more virulent, at a time when conditions allow, often as an off shoot of another type of infection.

Answer 4

Good question. Recent evidence seem to indicate that some of the infected peolple carried a mutated gene that actually kept the plague from killing them. They got sick but recovered. The people that didn't died.
