What kills Chagas disease?
What kills Chagas disease?
To kill the parasite, Chagas disease can be treated with benznidazole and also 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 transmits Chagas disease?
Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors that are found only in the Americas (mainly, in rural areas of Latin America where poverty is widespread). Chagas disease (T. cruzi infection) is also referred to as American trypanosomiasis.
How did Carlos Chagas discover Chagas disease?
In 1908, during an anti-malaria campaign in support of the construction of a railway track in the North of the state of Minas Gerais, the Brazilian hygienist and bacteriologist Carlos Chagas (1879-1934) (Figure 1) was made aware by a railroad engineer of large blood-sucking insects which lived en masse in local …
What states have Chagas disease?
Three states (Arizona, Texas, and Massachusetts) have made changes to their Chagas disease surveillance system since inception. In Arizona, a new case definition was applied in 2016 to classify blood donor cases with respect to confirmatory testing results from the reference diagnostic laboratory at CDC.
How do you test for Chagas disease?
During the acute phase of infection, parasites may be seen circulating in the blood. 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.
What organs does Chagas disease affect?
The heart is the most commonly affected organ in persons with chronic Chagas disease. Autopsy may reveal marked bilateral ventricular enlargement, often involving the right side more than the left, in the heart of patients who die of chagasic heart failure (see image below).
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.
How is Chagas diagnosed?
Is Chagas in the United States?
Most people with Chagas disease in the United States were infected in the parts of Latin America where Chagas disease is found. Although there are triatomine bugs in the United States, only a few cases of Chagas disease from contact with the bugs have been documented in this country.
Can a person with Chagas disease die from 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. Complications of chronic Chagas disease may include
What kind of treatment is there for Chagas disease?
Treatment. Treatment for Chagas disease is recommended for people diagnosed early in the course of infection (acute phase), congenital infection, and for those with suppressed immune systems. Many patients with chronic infection may also benefit from treatment. Patients should consult with their primary health care provider.
How does Chagas disease spread from person to person?
The cause of Chagas disease is the parasite Trypanosoma cruzi, which is spread from an insect known as the triatomine bug, or “kissing bug.” These insects can become infected by this parasite when they swallow blood from an animal that is infected with the parasite.
How long does the acute phase of Chagas disease last?
The acute phase of Chagas disease, which lasts for weeks or months, is often symptom-free. When signs and symptoms do occur, they are usually mild and may include: Signs and symptoms that develop during the acute phase usually go away on their own. If left untreated, the infection persists and, in some cases, advances to the chronic phase.
