infection should be conducted using 2 distinct assays.

Who is most at risk for Chagas?

Risk factors

The following factors may increase your risk of getting Chagas disease: Living in poor rural areas of Central America, South America and Mexico. Living in a residence that contains triatomine bugs. Receiving a blood transfusion or organ transplant from a person who carries the infection.

Should I be worried about Chagas disease?

Decades after being infected, about 30 percent of those who have Chagas develop serious health effects, including cardiomyopathy (disease of the heart muscle), heart failure, heart rhythm problems, and strokes. Less common are disorders that affect the digestive system.

How do you test for Chagas disease in humans?

Commonly used techniques include enzyme-linked immunosorbent assay (ELISA) and immunofluorescent antibody test (IFA).

Why would a blood bank want to know if you had ever been treated for Chagas disease before you could donate blood?

Why are blood banks screening for Trypanosoma cruzi infection, the parasite that causes Chagas disease? The transmission of Trypanosoma cruzi through blood transfusion is a recognized risk.

When should I get tested for Chagas disease?

Indications for Testing

Laboratory testing for Chagas disease is indicated in individuals who are at risk when clinical findings point to acute- or chronic-phase infection.

Is Chagas disease always fatal?

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.

Is Chagas disease a concern in the US?

People who have Chagas disease can be found anywhere in the world. However, transmission of the disease by kissing bugs (vectorborne transmission), only occurs in the Americas. Most people with Chagas disease became infected in rural areas of Mexico, Central America, and South America.

How much is a Chagas test?

Results: The cost of Chagas' disease test in the blood bank of Seccional Bolívar was COP$ 37,804 (USD$ 12), and the blood bag and immunohematology test costs were COP$ 25,941 (USD$ 8.2) and COP$ 6,800 (USD$ 2.2), respectively.

Can you get rid of Chagas disease?

To kill the parasite, Chagas disease can be treated with benznidazole or nifurtimox. Both medicines are nearly 100% effective in curing the disease if given soon after infection at the onset of the acute phase, including the cases of congenital transmission.

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.

How common is Chagas disease in USA?

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.

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.

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.

Where is Chagas most prevalent?

Chagas disease is common in parts of Mexico, Central America, and South America where an estimated 8 million people are infected.

What is the symptom onset of Chagas disease?

Symptoms of Chagas disease in the acute phase (the first few weeks or months) are: Mild, flu-like symptoms, such as fever, fatigue, body aches, and headaches. Rash. Loss of appetite.

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.

What is the mortality rate of Chagas?

Chagas disease causes approximately 10,000 deaths per year globally. Up to 30% of infected people develop symptoms. Chagas disease can cause: Stroke.

What states is the kissing bug found in?

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.

Does Chagas need to be treated?

Treatment for Chagas disease is recommended for people diagnosed early in the course of infection (acute phase), babies with congenital infection, and for those with suppressed immune systems. Many patients with chronic infection may also benefit from treatment.

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.

How do you know if you've been bitten by a kissing bug?

Kissing bugs can cause patches of bites, often around the mouth. The bites are usually painless, but they may swell and look like hives. Itching from the bites may last a week.

Can kissing bugs infest your house?

Triatomine bugs (also called “kissing bugs”, cone-nosed bugs, and blood suckers) can live indoors, in cracks and holes of substandard housing, or in a variety of outdoor settings including the following: Beneath porches. Between rocky structures. Under cement.

What is the incubation for Chagas disease?

After the incubation period of 1 to 2 weeks, infected patients enter the acute phase of Chagas disease. Transfusion- and transplant-associated cases may have a longer incubation period, sometimes up to 120 days.
