Field Photos: Guatemalan Anti-Chinche Campaign through Community-Based Integrated Vector Control (IVM)


The 15 photographs below illustrate activities aimed at integrated vector control in relation to the prevention and control of Chagas disease in poverty-prone rural areas of Guatemala. This initiative was launched by the Ministry of Public Health and Social Assistance (MSPAS) as part of the collaboration agreement between PAHO and the Japan International Cooperation Agency (JICA), within the Framework of the Initiative of Central American Countries against Chagas Disease (IPCA). Photos sent by Lic. Jun Nakagawa, PAHO-JICA Regional Advisor on Chagas, PAHO-Honduras, and taken by Lic. Ken Hashimoto, UNV (United Nations Volunteer) attached to PAHO Guatemala office.

The vectors responsible for transmitting the parasite Trypanosoma cruzi in Guatemala are the so-called 'chinches' Triatoma dimidiata and Rhodnius prolixus. These insects infest the adobe walls and thatched roofs of the dwellings occupied by poor people in rural areas.

Detection requires systematic searching

Integrated vector control means more than detection and spraying, however. It involves complementary IEC (information-education-communication) activities from human-resource development, teaching the populace how to work with the authorities to identify chinches and prevent infection, to teaching health workers, entomologists and epidemiologists the newest and most efficient techniques for dealing with the problem. Blood-testing is also carried out in infested areas. More photos on the Guatemalan project
