Chagas disease - Symptoms and causes

 Chagas disease symptoms.

Chagas disease, also known as American trypanosomiasis, is a parasitic infection caused by the protozoan parasite Trypanosoma cruzi. This disease is transmitted by blood-sucking insects, commonly known as kissing bugs, found in the Americas.

Symptoms:

Many people with Chagas disease do not develop symptoms, but if symptoms do appear, they can include:

Fever

Fatigue

Body aches

Headaches

Swollen lymph nodes

Enlarged liver or spleen

Skin rash or swelling

Difficulty breathing

Chest pain

Abdominal pain

Diarrhea or constipation

Loss of appetite

Nausea or vomiting

In some cases, the symptoms may appear years or even decades after the initial infection, and they can be severe and life-threatening.

Causes:

Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to humans through the feces of blood-sucking kissing bugs. The bugs feed on the blood of humans and animals, and when they defecate, they deposit the parasite in the skin.

The parasite can also be transmitted through blood transfusions, organ transplantation, and from mother to child during pregnancy.

Once inside the body, the parasite multiplies and can cause damage to the heart, digestive system, and nervous system over time, leading to severe and potentially fatal complications.
