Clean up the couch footprints that cats have stepped on Will there be toxoplasma gondii in the dust?

How is Toxoplasma gondii transmitted?

The first is to eat undercooked meat, especially pigs and sheep. Almost all mammals and birds, such as rodents, pigs, sheep, cattle, rabbits, chickens, ducks, geese, etc., can be infected with Toxoplasma gondii with a high infection rate. The source of human infection mainly comes from the meat of these animals, such as the temperature of the shabu-shabu is not enough and the time is too short, and the toxoplasma gondii is not killed, there is a risk of infection.

Contamination of raw meat or cutting boards can also be contagious. Contaminated sheep and milk can also be transmitted. The above-mentioned low rate of toxoplasma gondii infection in the Chinese population may be related to the habit of Chinese cooked meat.

Dogs can also be infected with Toxoplasma gondii, but their feces and excrement are not contagious and cannot be transmitted if they do not eat dog meat. Some people say that "dogs have a close relationship with people and are one of the important sources of human infection", and there are also children born who have "mental retardation, congenital heart disease, or an extra finger", and blame the family dog for this, all of which are unfounded.

Infected cat feces are an important source of infection. Cats and felines are the definitive hosts of Toxoplasma gondii, and infected cats excrete cysts in feces that generally last from 1 week to 20 days, and are rarely longer; This period is the contagious period. Worldwide surveys of about 1% of cat feces contain toxoplasmosis cysts.

The cysts in cat feces must develop in the outside world for 2 to 5 days before they are infectious, so it is very important to dispose of cat feces at the right time. Cysts can survive in water or moist soil for months or longer, so cat feces can contaminate food, water, and even dust that can be contagious. In areas where meat is fully delisen, felines are an important source of infection for humans.

However, many other animals that act as intermediate hosts can equally transmit. For example, there are many pastures with very few cats, and many cattle and sheep are infected; And there are still a few islands in the world that do not have cats, and the infection rate of the island's residents is still very high. Therefore, there is an important book "Human Parasitology" in China that says:

Due to the high infection rate of domestic animals, which are intermediate hosts, the contamination of cat feces is less important than eating undercooked meat in terms of the source of human infection.

It depends on whether your cat is infected with Toxoplasma gondii or not.

There is toxoplasma gondii in the feces of cats. I have a dog at home, and I didn't touch it when I was pregnant, so I took a cushion for himself when he went to the sofa, and used it every time he sat on the sofa. It will be more practical to ask the doctor to check the four eugenics once.
