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.

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.

Who should be screened for Chagas disease?

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.

How do u know if u have Chagas disease?

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

How long does it take for Chagas disease to develop?

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.

Chagas Disease - An overview

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.

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 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.

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 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.

How do you test for Chagas disease in humans?

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

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.

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.

How rare is Chagas disease?

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

Why is Chagas a silent disease?

Chagas disease is prevalent among poor populations of continental Latin America but is increasingly being detected in other countries and continents. It is often termed as a “silent and silenced disease” as the infected majority have no symptoms or extremely mild symptom.

Which country has the most Chagas disease?

Chagas disease is the most prevalent communicable tropical disease in Latin America. The most important vectors are the Triatoma infestans in Argentina, Bolivia, Brazil, Chile, Paraguay, Uruguay and Peru; the R. prolixus in Colombia, Venezuela and Central America; the T.

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.

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.

What does kissing bug poop look like?

Feces may be spread on walls and can be both white and dark, and usually look like stripes. Eggs can be found in wall crevices and are mostly white or pinkish. Consider using an Integrated Pest Management (IPM) approach including sealing cracks and gaps to prevent kissing bugs from entering your home.

What kills a kissing bug?

The most effective professional products for conenose bug control include wettable powder or microencapsulated formulations of pyrethroid insecticides such as cypermethrin, lambda-cyhalothrin, deltamethrin, or cyfluthrin.

What keeps kissing bugs away?

Tips for How to Get Rid of Kissing Bugs

Turn off any unused exterior lights to avoid attracting insects. Move any wood or debris piles away from the house. Use an insecticide spray with pyrethroid to control an infestation.

What organ does Chagas disease target?

Clinical course

Chronic infections are asymptomatic in two thirds of the human population. Chronic Chagas disease affects mostly the heart and the digestive tract.

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.
