English: This historic photograph showed the former Centers for Disease Control (CDC) Director, David J. Sencer, M.D., M.P.H., during his Directorship, in his office as he was pointing to a piece of artwork depicting what appear to be Triatomine sp., or "kissing bugs", which are known to transmit "Chagas disease". Dr. Sencer held the CDC Director’s position from 1966 until 1977. Also called "American trypanosomiasis" (tri-PAN-o-so-MY-a-sis), Chagas disease is an infection caused by the parasite Trypanosoma cruzi. Worldwide, it is estimated that 16 to 18 million people are infected with Chagas disease; of those infected, 50,000 will die each year.
