World Chagas Disease Day is observed every year on April 14 to raise awareness about Chagas disease, a neglected tropical disease primarily prevalent in Latin America. The day was first celebrated in 2020 and commemorates Carlos Ribeiro Justiniano Chagas, who first diagnosed the disease in a human on April 14, 1909.
Globally, around 8 million people are infected with the parasite causing the disease, highlighting the need for early detection, treatment, and prevention of transmission.
Background
- Approved at 72nd World Health Assembly (WHA) on May 24, 2019
- Officially established on May 28, 2019 (WHA plenary)
- Proposed by: International Federation of Associations of People Affected by Chagas Disease
- Supported by health institutions, universities, research centres, and organisations
Observance
World Chagas Disease Day is one of the 11 global public health campaigns recognised by the World Health Organization.
Other major WHO campaigns include:
- World Tuberculosis Day
- World Health Day
- World Malaria Day
- World Immunization Week
- World No Tobacco Day
- World Blood Donor Day
- World Hepatitis Day
- World Patient Safety Day
- World Antimicrobial Awareness Week
- World AIDS Day
What is Chagas Disease?
- A neglected tropical disease affecting mainly poor populations with limited healthcare access
- Also known as “silent or silenced disease” due to asymptomatic progression
- Caused By: protozoan parasite Trypanosoma cruzi (T. cruzi)
Modes of Transmission
- Vector-borne: Through triatomine bugs (“kissing bugs”)
- Congenital: From mother to child during pregnancy or birth
- Food-borne (oral transmission)
- Blood transfusion and organ transplantation
- Laboratory accidents
Vector Details
- Transmitted via faeces/urine of infected triatomine bugs
- Bugs live in:
- Wall and roof cracks
- Chicken coops, pens, warehouses
- Active at night, feed on human/animal blood
Disease Impact
- Slow progression, often asymptomatic initially
- 100 million people at risk
- Causes 10,000+ deaths annually
- Endemic in 21 Latin American countries
- Increasing cases in:
- USA, Canada
- Europe
- Africa
- Eastern Mediterranean
- Western Pacific
- Without treatment leads to:
- Severe cardiac disorders
- Digestive and neurological complications
- Can be fatal
Treatment and Prevention
Treatment
- Curable if treated early (acute phase)
- Drugs used: Benznidazole and Nifurtimox
- In chronic stage: Helps reduce complications and transmission
Prevention
- No vaccine available
- Effective measures:
- Vector control (reducing contact with insects)
- Improved housing conditions
- Blood screening
- Preventing transmission via pregnancy, transfusion, transplantation
