What is Chagas disease
Chagas disease is a parasitic infection often caused by contact with the faeces of infected blood-sucking insects (called kissing bugs) which infest people’s homes. The illness can also be passed on by eating food contaminated by the insects, through blood transfusions or organ transplants, or to children at birth.
After an often mild acute phase of a few weeks, with non-specific symptoms such as fever, body aches, rashes, diarrhoea, and vomiting, most people will go for a long time without showing any signs of the disease, people may be unaware they have the illness.
An estimated 30% to 40% of infected people will eventually develop serious complications, including heart disease and enlargement of the colon and oesophagus, which can incapacitate and quite frequently result in death.
People affected by Chagas disease6 million are infected with Chagas disease 21 countries in Latin American are endemic 75 million people are at risk of infection
WHO NTD roadmap targets for Chagas disease
The World Health Organization’s roadmap on NTDs set out a comprehensive plan for the control, elimination and eradication of various neglected tropical diseases by 2020, including Chagas disease.
Chagas disease target: Control by 2020
- By 2015, interrupted transmission by blood transfusion in the Americas, European and Western Pacific regions
- By 2020, interrupted transmission by intra-domiciliary vectors in Latin America
