In 2018 researchers suggested an alternative model in which "the disease was spread from human fleas and body lice to other people". The second model claims to better fit the trends of the plague's death toll, as the rat-flea-human hypothesis would have produced a delayed but very high spike in deaths, contradicting historical death data.

The most infamous flea-to-human transmitted disease is the bubonic plague, which was caused by the bacterium Yersinia pestis. The plague, fevers, tularemia: The diseases fleas can carry and how to ...
These cats and dogs could then expose humans to the plague when the animal brings those infected fleas around people. [4] However, like most bacterial systemic diseases, the disease may also be transmitted through an opening in the skin or by inhaling infectious droplets of moisture from sneezes or coughs. In both cases septicemic plague need ...

Plague, a disease that affects humans and other mammals, is caused by the bacterium Yersinia pestis. The human flea can be a carrier of the plague bacterium, although it is an exceptionally very poor vector of transmission. [4] Plague is infamous for killing millions of people in Eurasia during the Middle Ages. Without prompt treatment, the ...
NEW YORK CITY (PIX11) – Fleas capable of carrying the bubonic plague - sinisterly nicknamed the Black Death - have been found hitching rides in the fur of New York City's ubiquitous rats.
Yersinia pestis (Y. pestis; formerly Pasteurella pestis) is a gram-negative, non-motile, coccobacillus bacterium without spores that is related to both Yersinia enterocolitica and Yersinia pseudotuberculosis, the pathogen from which Y. pestis evolved [1] [2] and responsible for the Far East scarlet-like fever.
Theories of the Black Death are a variety of explanations that have been advanced to explain the nature and transmission of the Black Death (1347–51). A number of epidemiologists from the 1980s to the 2000s challenged the traditional view that the Black Death was caused by plague based on the type and spread of the disease.
