Avian Influenza
Urgent
Avian influenza is an infection caused by influenza A viruses that primarily affect birds but can occasionally infect humans and other animals. Human infections are uncommon but can sometimes cause severe respiratory illness. Most human infections occur after close or prolonged contact with infected birds, animals, or contaminated environments.

When to Seek Medical Attention
Avian influenza requires prompt medical assessment when infection is suspected because some strains can cause severe respiratory disease. Seek urgent evaluation for fever or respiratory symptoms following relevant exposure to infected birds or animals. Emergency care is needed for severe breathing difficulty, chest pain, confusion, bluish skin or lips, rapidly worsening pneumonia, or other signs of severe respiratory illness.

Overview
Avian influenza is an infection caused by influenza A viruses that primarily affect birds but can occasionally infect humans and other animals. Human infections are uncommon but can sometimes cause severe respiratory illness. Most human infections occur after close or prolonged contact with infected birds, animals, or contaminated environments.
Symptoms 3
Chest Pain
Dry Cough
Fever
Causes 1
Avian influenza is caused by influenza A viruses that naturally circulate among birds. Certain strains can occasionally cross the species barrier and infect humans, usually following exposure to infected poultry, wild birds, other infected animals, or contaminated environments. Human-to-human transmission is uncommon for most avian influenza viruses.
Infection
Risk Factors
Risk is mainly associated with close or prolonged contact with infected birds or animals, contaminated environments, or surfaces containing infectious material. People working with poultry or other potentially infected animals may have greater exposure. Risk can vary according to the circulating virus and local animal infections.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis of avian influenza requires laboratory testing because symptoms can resemble other respiratory infections. Testing may involve molecular methods such as polymerase chain reaction on respiratory specimens. A detailed history of contact with birds, animals, contaminated environments, and relevant travel or outbreak exposure is important when evaluating possible infection.
Prevention
Key Prevention Tips
Reducing contact with sick or dead birds and animals, avoiding contaminated environments, using appropriate protective equipment when exposure cannot be avoided, and practicing good hand hygiene can reduce risk
People working with poultry or infected animals should follow public-health and occupational infection-control guidance
Prevention Guidance
