We understand that many of our patients travel to different parts of the country and the world. The Center for Disease Control maintains an updated list of current outbreaks and endemic diseases. Click here to determine if your travel destination requires a vaccination not routinely administered in the United States. If you do need a specific vaccine, such as the Yellow Fever vaccine, contact the Maricopa County Health Department. This link will provide information on vaccine cost and availability, as well as department location and hours of operation.
