The blue rock pigeon (scientific name: Columba livia) has recently come under scrutiny due to its presumed role in carrying aspergillosis, a fungal infection that can affect both birds and humans.

About Aspergillosis

Aspergillosis is an infection caused by Aspergillus, a genus of molds that includes hundreds of species. The most common form of this infection is caused by Aspergillus fumigatus, which produces airborne spores. These spores can be harmful when inhaled in large quantities, especially in environments with poor ventilation or in people with weakened immune systems.

Transmission of Aspergillosis:
  • Airborne Spores: The disease is transmitted through the inhalation of spores that are released into the air by the mold. Common sources include:

    • Bird droppings: Especially pigeons, whose excrement can become a source of mold growth.

    • Soil, decaying vegetation, and compost: Aspergillus thrives in these organic matter environments.

    • Air-conditioning systems and old building materials: These can be breeding grounds for Aspergillus due to poor ventilation and moisture.

  • Environmentally Ubiquitous: Aspergillus is a common mold found in damp and poorly ventilated areas. It can also be found in grain, spices, and even dust.

Symptoms of Aspergillosis:
  • Respiratory Illness: Symptoms commonly include:

    • Cough and shortness of breath

    • Nasal congestion, headache, fatigue

    • In severe cases, people may cough up blood.

    Symptoms vary based on the type of aspergillosis (e.g., allergic bronchopulmonary aspergillosis or invasive aspergillosis), but respiratory symptoms are generally common across all forms.

Treatment:
  • Antifungal Medications: Treatment often involves antifungal drugs such as voriconazole or itraconazole, which help to inhibit the growth of the Aspergillus fungus.
