Avian influenza viruses occur naturally among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species.

These viruses are highly contagious among birds and can sicken and even kill certain domesticated bird species, including chickens, ducks, and turkeys.

Outbreaks of avian influenza in North American poultry and wild birds have occurred in recent years, but the risk to the general public in the United States is considered low.

Avian influenza mainly affects birds and only rarely infects humans.

People who handle sick or dead birds or hunters who process bird carcasses could be at higher risk of catching avian influenza.

Wild aquatic birds can be infected with avian influenza A viruses without showing signs of disease.

The current highly pathogenic avian influenza (HPAI) outbreak has been occurring in commercial and backyard poultry flocks across the United States since February of 2022.

HPAI was confirmed in dairy cattle in several states.

You can find more information on where HPAI has been detected in animals in the United States by visiting the U.S. Department of Agriculture (USDA) Highly Pathogenic Avian Influenza (HPAI) Detection website.

Avian influenza viruses are primarily found in aquatic birds and poultry, with waterfowl and shorebirds considered reservoirs for the virus.

These reservoirs can carry the virus with no health implications, making it difficult to detect and contain outbreaks.

Avian pox is a disease caused by various strains of the poxvirus that can affect many bird species, including eagles, songbirds, turkeys, and owls.

The disease is primarily transmitted by biting insects, but can also be spread through contaminated feed or water, or direct contact with infected birds.

To prevent the spread of avian pox, it's essential to regularly clean bird feeders with a 10% bleach solution.

Many bird species can be affected by avian pox, with different strains targeting different species.

The dry form of avian pox causes wart-like growths to develop on the unfeathered parts of the body, while the wet form causes labored breathing and difficulty eating.

In mild cases of the dry form, the growths may clear up on their own, but in severe cases, they can impede the bird's ability to see and lead to death.

The wet form of avian pox is often lethal, and can be caused by plaques developing on the mucous membrane of the mouth, throat, trachea, and lungs.

Avian pox has been reported in at least 60 species of birds, including turkeys, hawks, owls, and sparrows.

High densities of birds in small areas, such as apiaries, have greater transmission rates of avian pox.

West Nile Virus is a serious infectious disease that can be transmitted through mosquito bites. It primarily affects birds, with crows and jays being the most susceptible to mortality from the disease.

Birds that become infected with WNV often don't show any signs of illness, but if they do, symptoms can be severe and include uncoordinated walking, lethargy, tremors, inability to fly, blindness, and abnormal body posture.

Crows and jays will likely die if they contract WNV, but most other bird species are able to survive and fight off the disease if they become infected.

Humans and pets can also contract WNV from infected mosquitoes, and symptoms are often limited to headaches, mild fevers, and flu-like symptoms.

In rare cases, the disease can affect the central nervous system, causing encephalitis, meningitis, and death, but this only happens in less than 1% of infected people.

Most individuals infected with WNV, up to 80%, do not develop any symptoms, either mild or severe.

To avoid contracting WNV, it's essential to take precautions such as wearing long sleeves and pants, using mosquito repellents, especially during dawn and dusk when mosquitoes are most active.

Cryptococcosis is a serious condition that affects people with weakened immune systems. It's caused by a type of fungus called Cryptococcus neoformans, which is found in the droppings of wild birds like pigeons.

People who are immunocompromised are more likely to become ill with cryptococcosis, experiencing symptoms like headache, fever, cough, shortness of breath, and night sweats.

Dried bird droppings can be stirred up, creating a dust that can be inhaled by humans when they work, play, or walk in areas where birds have been.

Pets like dogs and cats can also become ill from dust containing cryptococcal fungi, but they can't spread it to other animals or humans.

The best way to avoid being infected with cryptococcal fungi is to avoid areas contaminated with bird droppings.

Psittacosis is a rare bacterial infection caused by Chlamydia psittaci that can be spread to humans from infected birds.

Most cases of psittacosis are associated with pet birds like parrots, parakeets, and cockatiels, as well as poultry like ducks and turkeys.

Birds can carry the bacteria without showing symptoms, but they only shed it in their secretions when they're sick.

Symptoms in birds may be subtle, but they can include lethargy, decreased appetite, and ruffled feathers.

Other signs of infection in birds include watery to thick whitish/greenish eye or nose drainage, eye redness, diarrhea, and green to yellow-green droppings.

If left untreated, severely affected birds may stop eating and produce sparse, dark green droppings before dying.

Symptoms of psittacosis in humans include fever, chills, headache, muscle aches, and a dry cough, with pneumonia often occurring.

Precautions should be taken when handling pet birds and cleaning their environment, such as washing hands diligently and wearing respiratory protection.

Here are some specific precautions to take:

House Finch Disease is a serious condition that affects many bird species, particularly House Finches. Infected birds show symptoms such as red, swollen, runny, or crusty eyes, conjunctivitis, and difficulty breathing.

The disease can be quite severe, causing birds to have crusted eyelids that obscure their vision. This makes it difficult for them to feed, and they may appear lethargic and fluffed up.

Some infected birds may recover, but many die from exposure, starvation, or predation. It's heartbreaking to see these beautiful creatures suffer.

Here are some common symptoms of House Finch Disease:

If you suspect that a bird in your area has House Finch Disease, it's essential to take action to prevent the spread of the disease. This can include providing a safe and clean environment for the birds, as well as taking steps to prevent the disease from spreading to other birds.
