A healthy guide to sucking cats and dogs
The soft cuteness of pets has installed more and more cloud shoveling officials, and has become an important family member and spiritual sustenance for people. While in close contact with humans, many microorganisms on pets will also communicate with humans, bringing health problems to shovelers. The mass media may have told you some pieces of information, and today we will talk to you about these things in detail and comprehensively.
"The Killer Who Never Breaks His Word"
rabies
Last month, a 15-year-old girl in Xiaoshan, Hangzhou, who died of brain death from rabies, stung the hearts of many people. Due to the lack of attention and timely injection of rabies vaccine, until 4 months after the injury, the children began to have symptoms such as limb numbness, headache, vomiting and photophobia, although they were quickly diagnosed and actively treated, but under the threat of nearly 100% mortality, the little girl still went to coma and brain death.
The king of cute pets, Wang Xingren and cats, are the most common carriers of this king of the virus, and most domestic pets have been immunized, but stray cats and dogs are not necessarily. Sick dogs are the main source of rabies transmission, infecting humans by biting humans and touching broken skin; cats and cats can also be infected with this virus, which in turn infects humans with "rabies", but in much less number than the authentic "rabies". And because felines have small barbs on their tongues (which are convenient for combing hair and licking off the flesh on their bones), even if there is no bleeding, the skin of the cat may already have a tiny wound after being licked by the cat; the skin of the child is delicate and especially vulnerable to injury.
The incubation period of rabies can range from 10 days to a year, and the virus can spread in the nervous system, developing into a deadly inflammation of the brain and spinal cord. Rabies vaccines are effective in blocking the spread of the virus to prevent infection. After being injured by a cat or dog, regardless of the depth of the wound, and regardless of whether the cat or dog has been immunized, it is necessary to inject rabies vaccine in time. It is worth noting that if the wound is located on the face, neck and other places close to the brain, the incubation period will be relatively short, even if the vaccine is given, there is still a possibility of infection.
"Gentle Tiger Touch"
cat scratch disease
What is cat scratch disease? If you are caught by a cat, will you get a cat scratch disease?!
Cat-scratch disease is a disease caused by infection with a pathogen called "Hansebartonella", which is manifested by symptoms such as fever and swollen lymph nodes. Hansebartona is usually found in the saliva of cats and also in cat's paws under the activity of cats. It can become infected after being bitten, scratched or licked by cats, and is more susceptible to infection if there is an open wound on the skin.
Unlike the sheer horror of rabies, cat's claw disease is mostly mild, and most conditions can be directly resolved by our immune system; severe diseases can be cured after timely diagnosis and targeted treatment. However, immunocompromised people may experience systemic spread or even death.
Based on this, bipedals should pay attention to the cleanliness of contact areas before and after playing with pets, especially when there are wounds on the skin. It is worth noting that cat scratching disease will not only be transmitted by cats to humans, dogs, rabbits, monkeys, pigs, cattle may be infected with Batonella, and people who are in close contact with these animals and injured may have this disease.
Real-life version of Clematis Invasion
Toxoplasmosis
Toxoplasmosis is a zoonotic disease caused by Toxoplasma gondii. It can develop in fish, birds, insects and other animals and a variety of mammals, including humans, but only in cats can sexual reproduction and then ovulate, and the eggs can be easily excreted from the body to maintain long-term vitality, ready to enter the next cycle of infection.
In the Korean movie "Clematis Invasion", clematis parasitizes the human body, causing human beings to be delirious, throwing themselves into the water to commit suicide, and the insect body can enter the water to multiply in large quantities. In real life, Toxoplasma gondii has a similar "mind control" ability: mice infected with Toxoplasma gondii are more eager to explore, and eliminate the fear of cats, are more likely to be eaten by cats, and promote toxoplasmosis spread and multiply.
After toxoplasma gondii infects humans, it can invade many parts of the body such as eyes, brain, heart, liver, lymph nodes and even eyes; after pregnant women are infected, pathogens can also infect the fetus through the placenta, affecting fetal development. Some studies suggest that toxoplasmosis is associated with schizophrenia and other psychiatric disorders.
For the health of shovelers and fur children, remember to feed them cooked food as much as possible and avoid contact between domestic cats and feral cats. Pregnant owners, even if they choose to continue living with them, should pause shoveling to avoid contact with possible eggs.
"The garbage truck is singing the vampire song"
Tick-borne disease
Ticks are small bugs the size of small fingernails that live in grass and bushes and specialize in sucking animal blood for a living. Since ticks can carry a wide variety of pathogens: Bunia virus, forest encephalitis virus, spirochetes, Rickettsia, Cox, Tula Francis, Babes ... It is simply a garbage truck, and when it bites, it will spread the corresponding diseases, causing fever, rash, platelet decline, lymphadenopathy and other symptoms. These diseases are not easily diagnosed and can even be life-threatening after delay in treatment. Qin Huiwen Wang in the TV series "The Legend of Mi Yue", after playing with Mi Yue in the wild, had a high fever, and then died soon after, there is a saying that it was because of the bite of a tick.
Daily with hair children to walk in the green, park play, they are easy to be stared at and stung by ticks, dense hair cover, insect body is not easy to be detected; in recent years, "adoption instead of purchase" trend, more and more caring people are willing to give wandering hair children a home, these little poor people are also likely to carry these ectoparasites. In close contact with humans, these parasites and carrier pathogens are brought to humans.
So when you have a hairy child at home, or take them out to play, you have to pull out their hair, spray insect repellent spray, or check the skin for bugs biting.
"Not one less"
Other diseases
01 Canine bite cocophilic fibrous infection
The rather awkward name of the bacterium, which is common in the mouths of cats and dogs, can be transmitted to humans through bites, scratches, licks, and even simple contact, which can lead to serious consequences such as human septic shock, endocarditis, meningitis, and even multi-organ failure. The normal human immune system can initiate interception, so the patients are mostly elderly people or children with relatively weak immunity. But even healthy people try not to let cats and dogs lick the more fragile mucous membranes such as noses and mouths.
02 Leptospirosis
Leptospirae is a slender, spiral-shaped microorganism that is often transmitted by contaminated water sources (i.e., "infested water"). Most animals, including dogs, are infected by contact or drinking infected water while playing outside, and pathogens enter the body through broken skin and mucous membranes, settle in the kidneys, and are constantly excreted outward through urine, infecting people and other animals. Human infection can cause damage to the function of various organs, especially diffuse bleeding of the liver, kidneys, brain and lungs, which is life-threatening.
Hook body disease is more common in warm and humid places such as Southeast Asia, but once the consequences of infection are serious, they cannot be ignored. So when you take your baby out, remember not to let them "help themselves" drink water everywhere.
03 Echinococcosis
Echinococcosis is a disease caused by echinococcosis infection, mainly due to dogs eating the raw internal organs of diseased livestock. After a sick dog is transmitted to humans, the human liver can appear large and small "blisters" - in fact, it is a luxury villa for parasites.
Echinococcosis is an endemic infectious disease, mainly found in Pastoral areas such as Tibet and Xinjiang. In the 1990s, Tibetan mastiffs were once popular throughout the country, but then for various reasons, they depreciated sharply, resulting in many Tibetan mastiffs in Tibet being released and wandering, and at that time, it was reported that many stray Tibetan mastiffs suffered from echinococcosis, and caused a considerable spread.
04 Fungal infections
Skin fungal infections often occur in both cats and dogs, which is the legendary "tinea annulum" and "tinea doris". After close contact with them, the owners may become infected and cause dermatosis.
05 Ascariasis
Sick animals can excrete eggs through feces, and if the shoveler's food is accidentally contaminated, it may become infected. The famous biliary roundworm disease is due to this product.
To introduce these to you, not to make everyone and the hair children have a gap, but I hope that everyone can better understand their cat life difficulties and dog life difficulties. Learn more about each other's vulnerability in order to get along better with them, I believe that after you learn the knowledge of this post, you will definitely receive the best love from the hairballs (^з^)-☆.
