Chagas Disease - An overview

What percentage of kissing bugs carry Chagas?

Scientists have found that about 50% of kissing bugs are infected with the Chagas parasite. Kissing bugs are a 'vector' because they can carry a parasite that can make people and animal sick. The parasite is Trypanosoma cruzi, and it causes Chagas disease.

Can you have Chagas and not know it?

Many people may remain asymptomatic for life and never develop Chagas-related symptoms. However, an estimated 20–30% of infected people will develop severe and sometimes life-threatening medical problems over the course of their lives. A dilated esophagus or colon, leading to difficulties with eating or passing stool.

Is Chagas disease a concern in the US?

More than 5 million people worldwide have Chagas disease. In the United States, there are estimated to be at least 300,000 cases of chronic Chagas disease among people originally from countries of Latin America where Chagas disease is endemic.

How rare is Chagas disease?

Chagas disease is endemic in 21 countries in the Americas, and affects approximately 6 million people. In the Americas, Chagas disease show an annual incidence of 30,000 new cases average, 12,000 deaths per year, and 8,600 newborns become infected during gestation.

Do all kissing bugs carry Chagas?

Kissing bugs can carry the parasite Trypanosoma cruzi, which can cause Chagas disease. It's important to know that not all kissing bugs are infected with the parasite, and the likelihood of contracting Chagas disease is low.

Should I be worried about kissing bugs?

The Bottom Line. Kissing bugs can transmit a parasite that leads to a potentially serious illness called Chagas disease. Most cases of Chagas disease occur in Latin America. Although infection directly from exposure to the kissing bug is rare in the US, it is still important to take steps to prevent kissing bug bites.

What state has the most kissing bugs?

Most of the world's kissing bugs are in Central and South America and Mexico. They've also been found in the United States in the lower 28 states, with higher concentrations in Texas, Arizona and New Mexico. Kissing bugs have been spotted a far north as Delaware, Ohio and Pennsylvania.

Can you survive Chagas disease?

Trypanosoma cruzi infection is curable if treatment is initiated soon after infection. In chronic patients, antiparasitic treatment can potentially prevent or curb disease progression and prevent transmission, for instance, mother-to-child infection.

Can you get rid of Chagas disease?

Once Chagas disease reaches the chronic phase, medications won't cure the disease. But, the drugs may be offered to people younger than age 50 because they may help slow the progression of the disease and its most serious complications.

How do you rule out Chagas disease?

The diagnosis of Chagas disease can be made by observation of the parasite in a blood smear by microscopic examination. A thick and thin blood smear are made and stained for visualization of parasites.

Can ivermectin cure Chagas disease?

Ivermectin and Chagas disease

To our knowledge, a connection between ivermectin and T. cruzi has never been described in the literature (in neither animal reservoirs nor humans). 1 17 To the best of our knowledge, there is currently no evidence that would justify CD treatment with ivermectin.

How soon can you test for Chagas?

Because parasitemia peaks during the acute phase of Chagas disease, testing techniques that detect Trypanosoma cruzi within a blood sample (eg, blood smear or polymerase chain reaction [PCR]) can be applied. By contrast, typically few or no parasites are detectable after 8-12 weeks of infection.

Do kissing bugs live in beds?

Kissing bugs can hide in cracks and holes in beds, floors, walls, and furniture. They are most likely to be found: Near places where a pet, such as a dog or cat, spends time. In areas where mice or other rodents live.
