Upper Respiratory Infections (Colds) And Acute Bronchitis

Colds are viral, not bacterial infections of the upper respiratory tract. Colds are highly contagious. They are spread through touching contaminated surfaces, coughing and sneezing. Some people are more prone to colds than others. A child in preschool may "catch" as many as four to eight colds per year. Generally, there is an increased frequency of colds during fall and winter months because of closer, indoor contact with other people.
