World Chagas Disease Day – April 14, 2025

World Chagas Disease Day celebrated annually on April 14, calls attention to the Chagas disease, a parasitic disease affecting more than six million people worldwide. As many as 300 babies are born with Chagas disease every year. Unfortunately, these babies remain undiagnosed owing to a lack of awareness. If the disease is not treated, people can die, or suffer a heart attack or stroke. Hence it is crucial to educate everyone about the disease so that appropriate measures are taken by the government, members of the community, and healthcare professionals to curb the spread.

History of World Chagas Disease Day

It was the year 1909 when a physician, Carlos Chagas, discovered the Chagas disease in a two-year-old girl called Berenice. From thereon began the journey toward discovering symptoms of the disease, its effects, and how it can be cured. These efforts greatly reduced the spread of the disease. But even though the risk of transmission has decreased, we have a long way to go before the disease is completely eradicated from the world.

To help researchers and doctors fight this disease, World Chagas Disease Day was established in May 2019 and celebrated for the first time in 2020. According to Dr. Marcos Espinal — Director of Communicable Diseases and Environmental Determinants of Health at the Pan American Health Organization (PAHO) — this day is important because it raises awareness about the Chagas disease and calls for actions required to prevent it. The holiday emphasizes the detection of the disease, its treatment, and devising solutions to stop transmission.

Chagas disease, also known as a ‘silent disease,’ is endemic in 21 countries. It is known to affect the poor because they lack proper healthcare and sanitation. The parasitic disease is caused by the microorganism ‘Trypanosoma Cruzi’ and can be transmitted to humans through insects. The infection is spread by blood transfusion, organ transplantation, contaminated food, and contact with feces/urine of infected triatomine bugs. The bugs that cause the disease usually become active at night and hide in the cracked walls of houses, animal pens, and warehouses.
