Increasing Numbers of Pigeons and Seagulls in Urban Areas
Seagulls are no longer limited to coastal regions; they have expanded into inland cities, towns, and landfills.
These birds have adapted their diets, now preferring to scavenge food waste instead of hunting fish or mice.
Similarly, pigeons have shifted from eating seeds and fruit to rummaging through our garbage.
Close Contact with Humans
Pigeons and gulls have adapted to living near humans, making it easy for them to find food. This close proximity raises the risk of disease transmission.
What Diseases Can Birds Transmit?
Here are some of the most common diseases that pigeons and seagulls can transmit to humans:
- Histoplasmosis: A fungal infection caused by Histoplasma capsulatum. Bird droppings, especially in large quantities, can carry the fungus. When the droppings dry and crumble, the spores become airborne. Inhaling these spores can lead to respiratory infections in humans.
- Cryptococcus: A fungus commonly found in bird droppings. Inhaling fungal spores can result in cryptococcosis, a respiratory infection that can be severe for individuals with weakened immune systems.
- Psittacosis: A bacterial infection caused by Chlamydia psittaci. It can be transmitted through exposure to infected bird droppings, respiratory secretions, or feathers. Symptoms in humans are similar to pneumonia or flu-like illnesses.
- Salmonellosis: Pigeons and seagulls can carry the bacteria in their digestive systems. Humans can become infected through contact with contaminated bird droppings or surfaces. Symptoms include diarrhea, fever, and abdominal cramps.
- E. coli and Campylobacteriosis: These bacterial infections can also be transmitted to humans through contact with bird droppings, particularly if proper hygiene is not followed.
Other Health Risks Linked to Bird Infestations
Some people may be allergic to proteins found in pigeon feathers, droppings, or dead skin. Exposure to these allergens can trigger allergic reactions, such as respiratory issues, skin rashes, or eye irritation.
Additionally, accumulated pigeon droppings can create slippery surfaces, raising the risk of slip-and-fall accidents, particularly in areas with high bird activity.
