What is Chagas Disease?
Chagas disease is a tropical parasitic disease caused by the protozoan Trypanosoma cruzi, transmitted mainly by triatomine bugs. It can cause severe heart and digestive complications if untreated.
Severe
Approximately 6-7 million infected worldwide; mainly in Latin America
No
Causes of Chagas Disease
Caused by the parasite Trypanosoma cruzi, transmitted through bites of infected triatomine bugs (kissing bugs). Also transmitted via blood transfusion, organ transplant, from mother to baby, and contaminated food/drinks.
Symptoms of Chagas Disease
Acute phase: fever, swelling at infection site (Romaña's sign), rash, fatigue, body aches. Chronic phase (years later): heart problems (cardiomyopathy), enlarged esophagus or colon, heart failure
Treatment & Types of Chagas Disease in Karnataka
Benznidazole or nifurtimox in acute phase and early chronic phase. Chronic phase treatment manages symptoms (pacemakers, surgery for digestive issues).
Chagas disease progresses through two distinct phases: the acute phase, occurring shortly after infection with mild or no symptoms such as fever and localized swelling, and the chronic phase, which can emerge years to decades later and includes an indeterminate form (infected but asymptomatic) and a symptomatic form causing serious heart or digestive tract complications.

Frequently Asked Questions
How do people get infected with Chagas disease?
It's mainly transmitted through the bite of infected triatomine ('kissing') bugs, though it can also spread via blood transfusion, organ transplant, or from mother to baby.
Is Chagas disease curable?
Antiparasitic treatment is most effective when given during the acute phase or early chronic phase; once significant heart or digestive complications develop, treatment shifts to managing those specific problems.
Can someone have Chagas disease for years without knowing it?
Yes, many people remain in the indeterminate chronic phase for years or decades with no symptoms before heart or digestive complications, if any, eventually appear.
What heart problems can Chagas disease cause?
Chronic Chagas disease can lead to cardiomyopathy, abnormal heart rhythms, and heart failure, which is why cardiac monitoring is important for those diagnosed.
How can I reduce my risk while traveling in affected regions?
Improving housing conditions, using insecticide-treated bed nets, and avoiding sleeping in poor-quality dwellings in endemic rural areas can significantly reduce exposure risk.
