Roundworm & hookworm can also be passed from pets to humans. Worms are picked up by humans walking on the ground where dogs have been. Roundworm eggs in dog feces can cause toxocariasis. Untreated toxocariasis can cause retinal damage and decreased vision. Dog feces can also contain hookworms that cause cuaneous larva migrans in humans.A bite or scratch from an animal can cause tetanus, rabies, or blood poisoning.
Rabies can be contracted from being bitten by a rabid dog, cat, bat or fox and is usually fatal. Beware of approaching any animal that appears to be "wild."
Cat scratch disease (CSD) a bacterial disease results from being bitten or scratched by a cat. Infection develops at the point of injury. Lymph nodes, especially those around the head, neck, and upper limbs, become swollen. About 40% of cats carry B. henselae at some time in their lives yet not show any signs of illness; you cannot tell which cats spread the disease. People with immunocompromised conditions are more likely than others to have complications of CSD. B. henselae has been found in fleas.
Brucellosis is an infectious disease of cattle, goats and pigs, caused by bacteria, and transmissable to man.
The bubonic plague, which killed many people in London many years ago, was spread by rats. The rats carried a parasite which caused an infectious disease characterised by swellings and fever. These rats inhabited sewers and unhealthy places. Today, the rats we keep as pets are clean and it's highly unlikely that they would pose a health threat.
Other conditions include parrot fever & avian flu from bird droppings, ring worm (a fungus) & mange (skin trouble).
Pregnant women should be careful when lifting heavy pets, or bags of dog food. They should also avoid unruly dogs who may jump up and knock them over. Pregnant women are off balance because of the extra weight they carry. A fall is serious for a pregnant woman.

Toxoplasmosis is an illness got from cat litter. The cat buries its excrement in a litter box, so the toxin sticks to the catís paws and are spread on ground wherever the catsí paws touch. It is also present wherever cat litter is dumped. Toxo during pregnancy can have a devasting effect because the infection is passed from mother to baby and can cause serious defects in the unborn baby including mental retardation, cerebal palsy, deafness, microcephaly (unusually small head) or hydrocephalus (unusually large head due to pressure on the brain). Toxoplasmosis may cause the woman may suffer a miscarriage or stillbirth. An infant born with the disease can suffer from jaundice, an enlarged liver. Symptoms may only appear in the teens - mental disabilities, seizures, hearing loss, eye infections and blindness.
