Fleas that could potentially carry plague found on New
York City rats

New
York City’s notoriously massive rat population appears to present a bigger
health risk than was thought before. According to a new study, the rodents’
fleas could transmit Bubonic plague.
GRAPHITTI NEWS based on media facts reports:
Scientists
from Columbia and Cornell Universities collected 133 Manhattan rats for their
research. The animals were euthanized while the insects living on them were
killed with a vapor. Some 6,500 parasites were found in the fur, including the
tropical rat mite, the spine rat louse, the spiny rat mite, and oriental rat
flea, which was discovered in almost a third of the rats. The Oriental rat flea
can carry Bubonic plague.
“However,
no evidence of [plague] infection was detected in fleas,” says the study,
published in the Journal of Medical Entomology on Monday reassures.
The
fact that some of the Big Apple’s parasites are able to transmit Bubonic plague
is still quite worrisome, as traces of the deadly disease are found on New York
subway’s trashcans and handrails, it has recently been revealed.
The
scientists who discovered Bubonic plague-carrying fleas, said earlier they had
discovered Manhattan rats were hosts to at least 18 new viruses. The finding
was then described as “a public health nightmare.”
Bubonic
plague killed an estimated 25 million people in Europe in the Middle Ages. And
the disease has not been completely eradicated. Last year’s outbreak in
Madagascar killed at least 47 people.
According
to the WHO, more than 13,000 cases of plague were reported between 2004 and
2013 – including 896 lethal cases. Africa had the highest number of those (97.6
percent).
