Catching diseases from caged birds is not a common occurrence, and simple precautions should suffice – i.e. keeping everything, including your hands, clean. However, at-risk groups with weak immune systems (infants, the elderly, the sick) should be far more cautious, and avoid handling birds altogether.
Can Humans Catch Diseases from Pet Finches?
Humans can catch diseases from any pet animal, if hygiene is poor. Classic disorders include bacterial infections such as salmonella, spread via infected bird droppings if you don’t wash your hands after cleaning cages. It’s not a common occurence, though, and a clean cage and clean hands all but eliminates the problem.
Some other possible nasties are worth mentioning, even though they are rarely an issue with pet finches.
Allergic alveolitis. This is a bronchial disease that occasionally affects humans, usually after several years’ contact with birds. This has earned it the name ‘pigeon fancier’s lung’, as a homage to those dedicated people who spend lots of time in pigeon lofts with their prized birds. It will only be a potential threat if you spend a lot of time in your aviary. The cause of the problem is dust from bird feathers and dried droppings.
If you develop asthma-like symptoms, speak to your doctor and mention your exposure to the birds. Continued exposure will only make it worse. In its chronic form, if the sufferer has failed to stop breathing in the irritant, the process can no longer be reversed, and lung capacity will be permanently diminished.
Asthma (in general). People prone to asthma may be affected by any bird, including pet finches. In severe cases the presence of a bird in the same room as the sufferer will bring on the wheezing and other symptoms, and the only solution is for that person to leave the room. Asthma sufferers with a less severe condition should be fine near finches, but may start to show symptoms if the bird is free-flying. This general asthmatic problem is not to be confused with the condition known as Allergic alveolitis, described above.
Catching a disease from a Canary or finch is uncommon... but it's not unheard of
Chlamydiosis or Ornithosis (more famously known as parrot fever (or psittacosis) due to its association with the main culprit species). This is a bronchial disease that usually lies dormant in a bird, without provoking symptoms; but it can still be passed on via droppings or saliva and other bodily fluids, or in body dust (dander) shaken from the feathers. In humans, ingesting or inhaling a dose of the Chlamydiophila psittaci bacteria responsible for the disease can, if you’re unlucky, lead to illness.
The word ‘unlucky’ is very appropriate, as many people work with birds all their lives without ever showing any symptoms of the disease. But it still pays to be cautious. Always wash your hands after handling pet birds or washing their cages.
Manifestations of parrot fever in humans range from flu-like symptoms and a sore throat, to high fevers and diarrhoea.
Giardia. This is one of several intestine-incubated nasties found in birds, and is similar to the more well-known salmonella. It’s transmitted via birds’ droppings, and can therefore contaminate cages, the finches’ water supplies, and the surrounding ground (if your birds are outside). Diarrhoea-like symptoms hail the onset of a rapid decline and death in birds; and humans who contract the disease will also suffer gastro-intestinal problems and sickness.

After reading about the breathing issues i am wondering if this is part of mine? my zebra finches have lived in my bedroom for 2 years and fly free, it is alot of daily cleaning and shit everywhere. i did not think i could get anything from them since they have never been in the wild, boy was i wrong. I at first when got them was bleaching everything until i learned that they could die from fumes so i bought animal environmentally friendly cleaners non toxic no smell to clean my room and their cage. Is there a type of vitamin or medicine i could add to their water dish to prevent illness? What does everyone else do to clean up after them? im daily and its exhausting but i dont like to have them caged its optional .Now im wondering if i have to put them in another room but they are so close to be i dont think they would do well alone they dont like when i leave the room for a whole day i have to go talk to them multiple times a day to cheer them up. Now im concerned for my health as well.
