How do you get tested for 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.

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 have Chagas disease and not know it?

It is estimated that as many as 8 million people in Mexico, Central America, and South America have Chagas disease, most of whom do not know they are infected. If untreated, infection is lifelong and can be life threatening.

When should you get tested for Chagas?

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.

Who should be screened for Chagas?

Women of childbearing age with risk factors and infants born to seropositive mothers deserve special consideration due to the risk of vertical transmission. Diagnostic testing for chronic T. cruzi infection should be conducted using 2 distinct assays.

KILLER DISEASES | How Chagas Disease Affects the Body

What is the initial symptom of Chagas disease?

Symptoms may include swelling at the infection site, fever, fatigue, body aches, rash and nausea.

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 Chagas go away on its own?

If untreated, infection is lifelong. Acute Chagas disease occurs immediately after infection, and can last up to a few weeks or months. During the acute phase, parasites may be found in the circulating blood. This phase of infection is usually mild or asymptomatic.

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.

Who is most at risk for Chagas?

Anyone exposed to the feces or urine of an infected kissing bug (triatomine) can develop Chagas disease. The infection is most common in rural or impoverished continental South America, Mexico and Central America.

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.

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.

Can blood test detect Chagas?

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.

How fatal is Chagas disease?

About 70-80% of people will remain asymptomatic for life and never develop Chagas-related symptoms. However, an estimated 20–30% of infected people will develop health problems years to decades later that are often fatal.

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.

Does Chagas affect the brain?

The involvement of the central nervous system (CNS) during human acute and chronic Chagas disease (CD) has been largely reported. Meningoencephalitis is a frequent finding during the acute infection, while during chronic phase the CNS involvement is often accompanied by behavioral and cognitive impairments.

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 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.

What states have 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.

Is Chagas disease an STD?

Conclusions: Evidence that Chagas disease can be transmitted sexually, coupled with the migration of individuals with Chagas disease to previously non-endemic countries and increased travel to endemic countries, has implications for public health.

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.

Where do kissing bugs usually bite?

The bugs might hit anywhere on the body, including the face, head, arms, and feet. Kissing bugs are so named because they like to bite around the mouth or eyes. You'll often see 2-15 bite marks in one area and maybe redness and swelling.

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.

Do kissing bugs live in beds?

Inside human dwellings, Kissing Bugs become crack and crevice dwellers like Bedbugs and cockroaches. Kissing Bugs emerge from hiding places at night and attack people in bed, much like Bedbugs will. When looking for a Kissing Bug infestation, generally follow the advice given for Bedbugs.
