🐞 What Is Chagas Disease?
- Caused by the parasite Trypanosoma cruzi, transmitted by triatomine bugs—commonly called “kissing bugs.”
- Infection occurs when the bug’s feces enter the body through eyes, mouth, or skin contact.
📍 Spread in the U.S.
- Once mostly found in South and Central America, Chagas is now appearing in U.S. states like California, Texas, Arizona, Louisiana, and Florida.
- A CDC study found human cases in eight states and recommends classifying it as endemic (regularly found in a region).
⚠️ Health Risks
- Acute phase: Fever, fatigue, rash, body aches, swollen lymph nodes.
- Chronic phase: Can lead to serious heart, digestive, and neurological problems; 20–30% of infected individuals may develop life-threatening complications.
- Romaña’s sign (eyelid swelling) is a common symptom.
🧪 Diagnosis & Treatment
- Two approved drugs: Benznidazole and Lampit (nifurtimox).
- Clinical trials for new treatments are underway.
- No vaccine currently available.
- Many healthcare providers are unaware of its local spread, complicating diagnosis and care.
🏠 Prevention Tips
- Clean rodent nesting areas like wood piles.
- Seal doors and windows; use screens.
- Apply residual pesticides near entry points if needed.
📣 Call to Action
- Experts urge public awareness, better testing, and education for healthcare professionals.
- Dr. Norman Beatty emphasizes the need for declaring Chagas endemic and investing in research and monitoring.
