Infants, the elderly and those who have underlying medical conditions such as diabetes, and lung or heart disease are particularly vulnerable to exposure.If you are experiencing any of the following symptoms, contact your health care provider: difficulty in breathing, chest pain or discomfort, and sudden onset of a cough or irritation of airways.
