Symptoms of Chagas Disease
One challenge with Chagas disease is that symptoms are often mild or absent during the early stages.
Acute Phase Symptoms
The initial phase may include:
Fever
Fatigue
Headache
Body aches
Swollen lymph nodes
Rash
Swelling near the bite site
Many people mistake these symptoms for a routine viral illness.
Chronic Phase Symptoms
Years or even decades later, untreated infections may contribute to:
Heart rhythm abnormalities
Enlarged heart
Heart failure
Digestive disorders
Swallowing difficulties

Because symptoms can remain hidden for years, early testing matters.
When to Seek Emergency Care
Most bites are minor.
However, emergency medical attention is necessary if you experience:
Difficulty breathing
Facial swelling
Lip swelling
Tongue swelling
Severe dizziness
Rapid heartbeat
Signs of anaphylaxis
These symptoms may indicate a serious allergic reaction requiring immediate treatment.
Medical Evaluation and Testing
If your healthcare provider suspects possible exposure, several tests may be recommended.
These can include:
Blood antibody testing
PCR testing
Physical examination
Follow-up monitoring
If results are initially negative, repeat testing may be advised because antibodies take time to develop.
Treatment Options
When diagnosed early, Chagas disease is treatable.
The two primary medications are:
Benznidazole
Nifurtimox
These medications work best during the acute phase.
Treatment decisions depend on:
Age
Overall health
Stage of infection
Individual risk factors
Early diagnosis offers the greatest chance of successful treatment.

Stay calm.
Wash the area thoroughly.
