Why did the disease The Black Plague seem to disappear in the winter?
The disease was spread by fleas on rats. During winter both the rats and the fleas became dormant thus there were no fleas to bite people and infect them with the plague.
Heat is a great bacteria breeder.
All the filth on the streets, left rotting in the height of summer would have bred bacteria very rapidly, spring and summer are after all known as breeding seasons.
In winter, most warmblooded creatures hibernate (even we humans tend to like to stay curled up with a cuppa and duvet).
So, not only the rats but the fleas and the bacteria too would have bred less during winter (this also would have given people time to develop a bit more resistance to the disease).
The Black Death disappeared in winter because the whole plague came from infected fleas, and in the winter, fleas are dormant, so the fleas couldn't bite people to spread the disease. However, in the summer, fleas are not dormant, so they continue to spread the Black Death to people. This is ironic because most sicknesses are worse in the winter than in the summer.
Black plague disease is bacterial. Plague is a bacterial infection found mainly in rodents and their fleas. But via those fleas it can sometimes leap to humans. When it does, the outcome can be horrific, making plague outbreaks the most notorious disease episodes in history. Bacterial-bubonic plague (AKA "the black plague") is caused by Yersinia Pestis.
The Black Death was a specific outbreak of the bubonic plague in the midieval time period. The most important animals carrying the bubonic plague were rats and the fleas of the species Xenopsylla cheopis that they carry. These animals were killed by the plague quite as effectively as human beings were, and the disease disappeared when it had killed off nearly all of the rats and fleas. In any given area, the plague usually ended…
Answer The Black Death is believed to have been caused by a bacterium, Yersinia pestis, and the disease is called bubonic plague. Answer The Black Plague was caused by the bacterium, Yersinia pestis, which was formerly Pasteurella pestis. The disease vectors were rodents, especially rats, and fleas. The Black Death or Black Plague was a specific outbreak of bubonic plague in Europe during 1346 to 1351.
The plague (AKA The bubonic plague) The Black Death was a horrible pandemic that killed over 75 million people. It is thought to be caused by a bacterium that caused several forms of plague. Experts believe that the Black Death started in Asia. Plague pandemic during 1346 to 1353. It is called Black Death. ADDITION: The exact disease is known as "The Bubonic Plague".
The "Black Plague" in Europe was bubonic plague. Bubonic plague is present in North America, but has never caused a major disease outbreak. Campgrounds in the Sierra Nevada mountains of California are occasionally closed because of plague, which is carried by rats and fleas. The biggest disease outbreaks in North America were smallpox and influenza.
Generically, a plague is a highly infectious epidemic disease, especially one with a high rate of fatality that spreads widely and rapidly through a population of animals. Specifically, the plague refers to a virulent, infectious disease that is caused by the bacterium Yersinia pestis transmitted primarily by the bite of fleas from an infected rodent. In humans the disease is called the "black death" as it causes black discolouration of the skin. A plague can…
The Black Death was a specific outbreak of the bubonic plague. In Europe it was mostly during the period of 1347 to 1350, though it lasted in some areas for a few years after that. It also devastated large parts of Asia. The bubonic plague is caused by bacteria of the species Yersinia pestis. Though the term bubonic plague is used as a term to cover all forms of the disease, there are three forms…
