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 ...
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 ...
Like other fleas, this species plays a role in spreading zoonotic diseases. [3] Rise in rodent outbreaks of zoonotic diseases can spread to humans, like the plague, rickettsioses, and bartonelloses. [3] They can also transmit pathogens that cause tularemia, Q fever, trypanosomiasis, and myxomatosis. [3]
In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), [1] [2] while more lethal varieties can cause SARS, MERS and COVID-19. [3] [4] As of 2021, 45 species ...
SARS-CoV-2, the causative agent of COVID-19, was first introduced to humans through zoonosis (transmission of a pathogen to a human from an animal), and a zoonotic spillover event is the origin of SARS-CoV-2 that is considered most plausible by the scientific community.
Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
Diseases caused by helminths are sometimes termed infestations, but are sometimes called infections. Arthropods such as ticks, mites, fleas, and lice, can also cause human disease, which conceptually are similar to infections, but invasion of a human or animal body by these macroparasites is usually termed infestation.
Fleas, spiders, termites, flies, centipedes, ants, bedbugs, cockroaches — these icky intruders won't give up. But keeping them away doesn't require expensive chemical pesticides.
