Entitled, “The Hajj and Disease Surveillance”, this image was created by CDC Health Scientist, John P. Abellera, MPH, in the Office of Surveillance, Epidemiology & Laboratory Services. This photo was taken in Mina, Saudi Arabia, on the first day of the Islamic pilgrimage to Mecca. The Hajj attracts more than 3 million Muslims, from over 140 countries, and poses serious disease outbreak concerns. The CDC Office of Global Health was invited by the Kingdom of Saudi Arabia, to provide epidemiologic and technical assistance to KSA’s Ministry of Health in the use of mobile technology, and data analysis to enhance disease surveillance. This photo earned John a tie for the Second Place award in the 2012 CDC Connects Annual Public Health in Action Photo Contest, in the category of “International Programs”.
