Transmissible diseases from dogs to humans

We have investigated in terms of contagion, whereby it is Transmissible diseases from dog to human respectively. from human to dog acts.If two-legged and four-legged friends live together, they often come quite close to each other. The fact that microorganisms and transmissible diseases are exchanged here (in addition to proofs of love) does not seem surprising.

These can, however, sometimes be pathogens. With what can dog. infect humans now? And more importantly, how can it be prevented?

For your information: Infectious diseases that can be transmitted between humans and animals are called zoonoses. On the one hand, you can be infected with them directly. Thus, in contact with infected persons, their pathogenic microorganisms can migrate.

On the other hand, infection can also occur indirectly, through so-called vectors. These are disease vectors that infect a host – a dog or a human, for example – and spread from it to others. Typical vectors are ticks or mosquitoes. The host, usually our four-legged friend, is in this case not directly responsible for an infection, but nevertheless provides for the transmission.

Germs and risk groups

There are many zoonotic pathogens. They range from viruses. from bacteria to fungi to parasites. Some of them can cause serious diseases. For many, however, the consequences are more unpleasant than worrisome.

Nevertheless, there are people who are particularly susceptible to infection. The risk group includes children, pregnant women and the elderly, as well as anyone with a weak immune system. Increased precautions should be taken with them. One thing should be said, however: In general, humans. dogs do not pose a serious health risk to each other. Infections are possible, but not the rule. More often infected by two-. Four-legged friends infect their own kind.

Few health hazards emanate from humans in particular. "The biggest one for the dog is certainly overfeeding," says veterinarian Eva Mlacnik with a twinkle in her eye.

Cold, flu and influenza

Colds and flu infections are always in high season. The experts interviewed agree here, however: there is no risk of infection for the dog!

However, the real flu also exists in dogs. The influenza viruses H3N8 and H3N2, as the dog flu pathogens are technically called, cannot be transmitted to humans, but caution is still advised!

According to cell researcher Judith Secklehner of Imperial College London, humans can transfer viruses from infected dogs to healthy ones. The viruses survive up to one day in the clothing.

Anyone who has had contact with a sick dog should wash their hands carefully and change their clothes.

What crawls and flies

Especially with dog-human-zoonoses one thinks probably very fast of parasites. In fact, certain species of fleas, mites, worms and ticks can be transmitted to humans with greater or lesser probability respectively. "A parasite infestation of the dog by humans does not actually occur with normal Central European hygiene standards," says Herbert Auer of MedUni Vienna. For quadrupeds there is here therefore all-clear; master. Mistresses can at least take precautions!

Worms

"Among parasitic zoonoses, canine roundworm probably plays the biggest role," says Herbert Auer of MedUni Vienna. It is transmitted (to humans. Other animals) about the dog excrement. After a few weeks in the air, larvae form in it, which can enter the mouth and body through unwashed wild strawberries, dirty hands and the like.

If canine roundworm develops, the most common symptoms are pain in the pit of the stomach and jaundice. Similarly it behaves with the fox or dog tapeworm, which can occur both with the dog. In these worm diseases, however, the feces is immediately infectious and does not require a maturation period.

However, according to Auer, transmission to humans is much rarer. Infections can be prevented by regular hand washing. Periodic worming for our four-legged friends.

It is also important to consistently clean up the dog's poop – even when walking in the woods or meadows! Veterinarian Eva Mlacnik adds: "When barfing, worming should be done monthly at best!"

Mites and fleas

Cheyletiella and Sarcoptes mites, also known as fur mites and burrowing mites, are among the most prominent defectors. They live – like the dog flea – on the skin or in the fur of dogs and can be transmitted to them through contact with their owners.

In humans, they cause soft skin flakes and punctures, which appear in the form of small red dots. Most of the time, the symptoms occur on the parts of the body where dog and owner touch each other while cuddling. But veterinarian Eva Mlacnik reares: "In principle, transmissions to humans are not the rule. However, it is quite easy to take precautions: By regularly administering parasite prophylactics!"

Curious: caries is also contagious!

Unbelievable but true: caries pathogens can be transmitted. Especially when discarded toothbrushes are reactivated for the quadruped. Matthias Eberspacher-Schweda of the Vetmed Vienna advises therefore: "An own. Above all, use unused toothbrush for Bello! Saves money. Pain above all.

Ticks

Ticks – among them especially the common wood tick – infest humans and dogs alike. If a tick has attached itself, it poses no risk of transmission. If this has not yet happened, it could be transferred from one to the other. "However, it is not the rule, because most of the time we get ticks in nature," states Mlacnik.

Ticks are hardly dangerous for dogs anyway: the TBE virus shows no symptoms in them. Veterinarian Eva Mlacnik has an important tip for removing ticks from dogs: "Never twist them out with your hands, but always use tick tongs! This is the only way to protect yourself from a Borrelia infection!
