Infectious diseases of people and animals can now be prevented by vaccines and other methods.
First, dogs spread diseases.
The main host of rabies virus is wild animals, but human rabies virus is mainly carried and spread by dogs and cats. It should be noted that seemingly healthy dogs also carry viruses to spread rabies. The incubation period of rabies is as short as 5 days and as long as 19 years or longer, usually 1-3 months. If it is highly toxic or aggressive, the wound is close to the head, or the old and weak, the incubation period of the virus is relatively short. The typical symptoms after the onset are "anxiety, irritability and insomnia, sensitivity to stimuli such as sound, light and wind, and a feeling of tightness in the throat", which is also called "water phobia" by the people.
Dogs with rabies have behavior changes at the beginning of the disease, with drooping tails, listlessness, less food and indifference to their owners. After about 2 days, it entered an excited state, its cry changed and it wandered around. When he walked, he walked straight with his head down and his tail between his legs. He often bites other animals suddenly, swallows foreign bodies, disowns acquaintances, sticks out his tongue and drools a lot. Later, it developed into hind limb paralysis and died of respiratory center paralysis. It takes about 3-7 days from onset to death.
Second, diseases transmitted by cats.
Toxoplasma gondii: Toxoplasma gondii is easy to parasitize cats. After being infected, people may have symptoms such as fever, general weakness, conjunctivitis, muscle soreness, joint pain, and swollen lymph nodes. When a woman gets sick during pregnancy, it will do harm to the fetus, resulting in abnormal development of the baby, hydrocephalus, microcephaly, microcephaly, disturbance of consciousness or movement, etc.
2, cat scratch disease: cats can also cause "cat scratch disease", which means that after people are scratched or bitten by cats or dogs, painless papules appear near the scratch (bite) within 1 ~ 2 weeks, lymph nodes are swollen, and local purulent.
3. Beware of pneumonia when raising pigeons.
Pigeons carry many fungi, such as Cryptococcus neoformans. When people are in close contact with pigeons, Cryptococcus neoformans enters the human body through the respiratory tract, causing lung inflammation, so patients have symptoms such as fever, cough, spitting, chest pain and asthma.
Doctors call it "pigeon-eating pneumonia", and the symptoms are coughing and shortness of breath due to contact with pigeons. If cryptococcus causes meningitis, the consequences will be more serious.
Fourth, the precautions for keeping pets to prevent diseases
In order to prevent people's pets from getting sick, we must first control the "quality" when buying pets. From the appearance, the pet should be mentally normal, clean around the anus, free from fleas, mites and other surface parasites, clean skin, free from pustules, eczema, alopecia and other phenomena. To help stray animals, it is necessary to help them do a good job of repelling insects in vivo and in vitro.
Pets should have regular health checks and vaccinations, which can prevent many infectious diseases. Bathe cats, dogs and other pets regularly, disinfect and clean utensils and bedding, and try not to let pets enter the bedroom, let alone sleep with them. Once bitten by a cat, dog or mouse, you should go to the health and epidemic prevention station for rabies vaccine within 24 hours. In addition, it is necessary to nip in the bud and insist on vaccinating pets regularly according to regulations.
