What causes conjunctivitis?

The three main types of conjunctivitis are infectious, allergic and chemical. The infectious form, commonly known as "pink eye," is caused by a contagious virus or bacteria. Your body's allergies to pollen, cosmetics, animals or fabrics often bring on allergic conjunctivitis. And, irritants like air pollution, noxious fumes and chlorine in swimming pools may produce the chemical form.

Small children, who may forget these precautions, should be kept away from school, camp and the swimming pool until the condition is cured.
