Overview

Hay Fever
Hay fever, also called pollen allergy or seasonal allergic rhinitis, occurs when the immune system reacts to airborne allergens such as pollen. It commonly causes sneezing, a runny or blocked nose, itching of the eyes, nose or throat, watery eyes, coughing, and postnasal drainage. Symptoms may occur during seasons when trees, grasses, or weeds release pollen into the air.
Avian Influenza
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.

Diagnosis

Hay Fever
Hay fever is usually diagnosed from the pattern of symptoms, their seasonal timing, and a physical examination. The healthcare provider may examine the nose, eyes, throat, and other areas affected by allergies. When the specific allergen is unclear or symptoms are difficult to control, allergy testing may be performed using skin tests or blood tests to identify relevant triggers.
Avian Influenza
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

Hay Fever
Hay fever symptoms can be reduced by limiting exposure to pollen and other known allergens. During periods of high pollen, keeping windows closed, reducing outdoor exposure, and changing clothes after spending time outside may help. Showering can remove pollen from the skin and hair. Saline nasal rinsing may also help clear allergens, but sterile, distilled, or properly treated water should be used.
Avian Influenza
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.

Risk Factors

Hay Fever
The likelihood of hay fever is higher in people who have allergies or a family history of allergic conditions. Repeated exposure to pollen and other environmental allergens can trigger symptoms. Seasonal pollen levels, geographic location, and outdoor exposure influence when symptoms occur. People with other allergic diseases may also be more likely to experience allergic rhinitis.
Avian Influenza
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.
