Introduction: Hay fever
Hay fever: Hay fever is a common nasal allergy to airborne substances such as pollens or molds, and the term has also been used for other allergies such as to animal dander. It is very common with an estimated 35 million Americans with pollen allergies alone. Hay fever is also known as "allergic rhinitis".
Symptoms are often similar to a cold
with runny nose, tearing, sneezing, and so on.
Another possibility that must be ruled out is asthma.
There are also numerous subtypes of hay fever,
and it is desirable to determine exactly what is causing the allergy.
One key factor is whether symptoms are seasonal, especially for pollen allergies,
or year-round as for some other types of allergies.
