What is Chagas Disease?
Chagas disease,also known as American trypanosomiasis,is a parasitic infection caused by the protozoan parasite Trypanosoma cruzi. It’s primarily found in Latin America, but as recent reports indicate, it’s increasingly present in the United States, including a confirmed case in California. The disease is spread to humans through contact with triatomine bugs, often called “kissing bugs,” which are infected with the parasite.
How is Chagas Disease Spread?
The primary mode of transmission is through the feces of infected triatomine bugs. These bugs typically feed on blood at night, often biting people on the face (hence the nickname “kissing bug”). The parasite enters the body when the person unknowingly rubs the infected feces into the bite wound,eyes,or mucous membranes. Other, less common, transmission routes include:
- Blood Transfusion: Receiving blood from an infected donor.
- Organ Transplantation: Receiving an organ from an infected donor.
- Congenital Transmission: A pregnant woman with Chagas disease can transmit the parasite to her baby.
- Contaminated Food or Drink: Rarely, through ingestion of food or drink contaminated with infected triatomine bugs or their feces.
Symptoms and Stages of Chagas Disease
Chagas disease typically progresses through two main phases: the acute phase and the chronic phase.
Acute Phase
The acute phase occurs shortly after infection. Many people experience mild or no symptoms,making diagnosis challenging. When symptoms do occur, they can include:
- Fever
- Headache
- Body aches
- Swelling at the site of the bite
- Enlarged lymph nodes
Chronic Phase
If left untreated, the acute
