As a set, those diseases are called zoonoses (ZOH-uh-NOE-sees).
Most of the sicknesses we select up from dogs and cats rise up from bacteria, single-celled and wormlike parasites, and one virus (rabies). People with compromised immune systems (which includes people with AIDS or those taking pills to thrust back rejection after receiving an organ transplant) and kids are at the highest threat of becoming unwell with such ailments

The dog or cat that unknowingly transmits those germs normally suggests no symptoms of infection. But as soon as inside a human, these bacteria can motive pores and skin infections, flu-like symptoms which include fever and chills, and more severe diseases together with meningitis.
The rabies virus is the most risky saliva-borne germ a cat or canine can bestow on a person. Thankfully, rabies in people is very uncommon within the U.S. (handiest 47 cases had been stated among 1990 and 2005), and maximum of those instances are attributed to bites from wild animals together with bats and raccoons.

Also, the eggs of intestinal worms—such as roundworms, hookworms, and tapeworms—are typically shed in animal feces, and people who by accident ingest them can get emerge as sick. Only the tapeworm can change into an person parasite in the human gut, however the other worms in immature shape can migrate to the pores and skin, eyes, and different organs.
As if that weren’t enough, cat feces can deliver a microscopic parasite (Toxoplasma gondii) that causes enlarged lymph nodes. Infected people normally don’t show symptoms, except they’ve a weak immune machine. Most important, ladies inflamed with toxoplasma during being pregnant can transmit the parasite to their developing fetus.
