Approximately 4.8 million children in the United States under the age of 18 have asthma, the most common chronic illness among children.[74] The incidence of the disease is on the rise, increasing nearly 40 percent among U.S. children between 1981 and 1988.[75] Other countries are also observing rising rates of asthma. Blacks, Hispanics, and people living in urban areas appear to be at greatest risk for the disease.[76] Asthma is a complex disease associated with many factors including genetics, allergies (cockroaches and dust mites), mildew, molds, and the environment. Asthma is a condition of the airways characterized by chronic inflammation and episodic limitation of the flow of air into and out of the lungs. Symptoms of the disease include coughing, tightness in the chest, shortness of breath, and wheezing. Exacerbations of asthma have been linked with exposure to ambient air pollutants, indoor air pollutants, as well as allergens.

Based on increased hospital admissions, increased hospital emergency room visits, and increased medication use, ambient air pollution is associated with aggravation of asthma. In a recent study of children at an asthma summer camp, ozone air pollution was significantly correlated with an increase in the use of asthma medication and the worsening of other asthma symptoms.[77] The children were 40 percent more likely to suffer asthma attacks on high pollution summer days. In another study, researchers reported a 37 percent increase in hospital emergency visits for childhood asthma after periods of maximum ozone pollution levels.[78] A study in Mexico City showed an association between increased levels of particulate matter and ozone and a worsening of respiratory symptoms among mildly asthmatic children.[79] Hospital admissions among children with asthma in Toronto were higher after days with elevated ozone levels.[80]Keep indoor air as clean as possible. Do not smoke cigarettes indoors. Keep your house free from dust and mildew. To control dust in the home, remove wall-to-wall carpets when possible and replace them with small area rugs that can be thoroughly cleaned. Periodically remove and launder heavy curtains. Be sure that fumes from gas stoves and heaters are properly vented, and reduce indoor sources of pollutants such as insecticides, wood fires, cleaners, solvents, and deodorizing sprays. When painting or using chemical cleaning agents, assure full ventilation.
