World Chagas Disease Day
WHO observance
WHO observance
This authority record treats the observance as a fixed annual date. The same month and day can be reused unless a stronger source changes the rule. Public-holiday or government status is never inferred from the observance name alone.
Overview
World Chagas Disease Day is observed on 14 April to increase awareness of Chagas disease and improve visibility for people and communities affected by it.
The World Health Assembly established the day in 2019, and the global community observed it for the first time on 14 April 2020.
Why it matters
Chagas disease is a neglected tropical disease, and awareness matters because infection may remain unnoticed for long periods while access to diagnosis and care can be uneven.
The observance is therefore useful for public-health education, reducing stigma, strengthening access to appropriate services and keeping affected communities visible in health planning.
History
The proposal for a World Chagas Disease Day was initiated by the International Federation of Associations of People Affected by Chagas Disease and supported by health, research and civil-society organizations.
The Seventy-second World Health Assembly adopted decision WHA72(20) in May 2019, establishing World Chagas Disease Day on 14 April.
The first global observance took place on 14 April 2020. The date recalls 14 April 1909, when Brazilian girl Berenice Soares de Moura was diagnosed by Carlos Chagas in the first documented human case associated with his description of the disease.

Invite a qualified public-health or clinical professional to explain locally relevant testing and care pathways where Chagas disease is a concern.
Include the perspectives of people affected by Chagas disease and avoid language that stigmatizes countries, communities or modes of transmission.
Support evidence-based awareness, screening or treatment-access programmes run by competent health authorities and organizations.
Anyone concerned about personal exposure, symptoms, pregnancy, blood donation or treatment should seek advice from an appropriate health professional or local health service.
