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.
Mononucleosis
Infectious mononucleosis, often called mono, is a contagious viral infection. It commonly causes extreme tiredness, fever, sore throat, swollen lymph nodes, and sometimes an enlarged spleen or liver. Most cases are caused by Epstein-Barr virus. Symptoms often develop gradually and most people recover, although fatigue can continue for several weeks or occasionally longer.

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.
Mononucleosis
Diagnosis is based on the symptoms and physical examination, including examination of the throat and lymph nodes and checking for enlargement of the liver or spleen. A healthcare provider may order blood tests to look for changes associated with mononucleosis or antibodies to Epstein-Barr virus. A rapid mono test may be used in appropriate circumstances, although additional testing may be needed when the result is unclear.

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.
Mononucleosis
There is no vaccine that prevents infectious mononucleosis. The risk of spreading the infection can be reduced by avoiding kissing and by not sharing food, drinks, utensils, or lip balm with someone who has mono. Good hand hygiene is also useful. Because the virus may remain in saliva after symptoms improve, people should follow appropriate precautions during recovery and according to medical advice.

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.
Mononucleosis
Mononucleosis is particularly common among teenagers and young adults, although infection can occur at any age. Risk increases with close contact with an infected person because the virus is commonly spread through saliva. Sharing drinks, food, utensils, or personal items that contact saliva can also transmit the infection. Previous lack of exposure to Epstein-Barr virus may make a person susceptible to symptomatic infection.
