Duration: A"cold" will generally last ten to fourteen days. It can occur at any time of the year. It can have similar symptoms as "hay fever", runny nose, nasal congestion, sore throat, watery eyes. Depending on the type of virus there may be fever with a "cold". There is no fever with "hay fever". "hay fever" generally implies seasonal allergies, so spring, summer or fall.

Itchy eyes or fever: Hay fever is caused by exposure to allergens. Colds are caused by germs. Both can give you a runny and or stuffy nose with sneezing, but allergies often cause itchy eyes as well. If there is a fever than an infection is typically the cause but not all infections cause fever. Heyfever often lasts for weeks, colds should resolve in several days.

What is the difference between hay fever and a cold?

Hay fever vs cold: From a practical perspective, the symptoms of both of these disorders are the same--runny nose and sneezing, perhaps also with itching, running eyes. The difference is that a cold will only last 3-4 days usually, while allergy symptoms tend to be chronic (eg., last all spring). So if your cold symtpoms don't quit after a week, you probably have allergies.

you also won't get a fever with hay fever...the term comes from many years ago when people had symptoms from ragweed during the hay "cutting" season and felt very warm....

How could i tell if I have hay fever or a cold?

Time: Early on the symptoms may seem similar, but a cold will resolve after 7-10 days while allergies are more prolonged. With hay fever (allergic rhinitis) there is more itching and sneezing and the nasal mucus is predominately clear and watery. Frequently there are eye itching, redness with allergies and no fever. Allergies respond to antihistamines more so than colds.
