Data Source For Areas Affected
The maps designate countries considered to be affected by a disease. Areas within countries may or may not be affected by a specific disease. Consult with a Travel Healthcare Provider or www.cdc.gov/travel about your specific itinerary prior to travel. Reporting activity data are provided by Sitata and derived from numerous sources, including official surveillance data and news reports. Reporting activity does not reflect current risk of infection with a disease. Not all areas report cases of disease; therefore, the absence of activity on the map does not indicate that a disease is not present. The relationship between the intensity of reporting activity and actual disease transmission is unknown and does not indicate a difference in risk. Maps do not reflect differential distribution of diseases within a country.
