Colds and allergies have many of the same symptoms, but there are differences between the conditions. Colds are the result of a virus, while allergies represent the body s physical reactions to airborne particles called allergens that you inhale. Cold symptoms are often the same.
Allergies can last a week, a month, or continue all year long.
Sneezing and runny nose occur the first day of a cold and last five to seven days. Some of the most common allergens such as house dust, dander on the fur of cats and dogs, or mold spores circulate in the air throughout the year. Vacuum thoroughly and often. Use a high filtration vacuum bag. Remove thick carpets and heavy, lined draperies.
