Beware: Chagas Disease Is The "New AIDS Of The Americas"

A little-known life-threatening illness caused by blood sucking insects has been labeled the "New AIDS of the Americas" by leading health experts.
According to a report, the parasitic illness called Chagas Disease has similarities to the early spread of HIV.
The said disease was once largely contained to Latin America but is now spreading into the United States due to the increases in travel and migration. Chagas is usually transmitted from the bite of blood-sucking insects called Triatome bugs which release a parasite called Trypanosoma cruzi into the victim's bloodstream.
The Triatome bugs are black wingless beetles about 20 mm in length and is commonly known as the kissing bugs. The disease spreads easily either through blood transfusions or, less commonly, from mother to child. Like AIDS, the illness is difficult to detect and has a long remission period.
Symptoms of the Chagas disease may include constipation, abdomen pain, enlarged heart and enlarged intestine that can burst suddenly causing instant death, according to experts. An estimated 10 million people worldwide has been already infected with the disease with most sufferers in Central America, Colombia, Mexico and Bolivia, as well as approximately 30,000 people in the United States, according to the New York Times.
Chagas is considered one of the Neglected Parasitic Infections that have been targeted by the Centers for Disease Control and Prevention (CDC) for public health action.

Chagas Disease vs AIDS: 6 Differences and 5 Similarities
Jun 1, 2012 | 2:58 PM ET | Rachael Rettner, MyHealthNewsDaily Staff Writer
The condition known as Chagas disease has created a situation in the Americas that resembles the HIV/AIDS epidemic in its early years, one group of researchers argues.
"As with patients in the first two decades of the HIV/AIDS epidemic, most patients with Chagas disease do not have access to health care facilities," or essential medications, the researchers, who are working on a vaccine for Chagas disease, write in the May issue of the journal PLoS Neglected Tropical Diseases.
Both diseases are also stigmatizing, the researchers say. And for U.S. immigrants with Chagas disease living illegally in the United Status, immigration status can be an obstacle to receiving treatment, just as sexual orientation was a barrier to care for HIV/AIDS in the beginning of the epidemic, the researchers say.

But there are also big differences between the illnesses. Here's how the disease compare:
[HI]6 differences
[/HI]Chagas disease is caused by a parasite, specifically, a single-celled protozoan called Trypanosoma cruzi. HIV/AIDS is caused by a virus.
Chagas disease is typically transmitted to people from insects called triatomine bugs, or kissing bugs. These bugs carry the parasite, and transmit the disease when they bite. Because the parasite usually lives in another organism to being passed to a person, it is known as a vector-borne illness. HIV/AIDS is transmitted directly from person to person through sex, or sharing intravenous needles.
When Chagas disease develops into a chronic condition, it can affect the heart, intestine and esophagus. HIV/AIDS affects the body's immune system.
HIV/AIDS is almost always fatal without treatment. Most people with Chagas disease (about 70 percent), do not develop chronic symptoms, according to the National Institutes of Health.
Although it's uncommon, Chagas disease can be transmitted orally, when people consume food contaminated with fecal matter from triatomine bugs (this transmission has been documented in the Amazon). HIV/AIDS cannot be transmitted this way.
HIV/AIDS affects people all over the world, and the biggest burden is in Sub-Saharan Africa. Because triatomine bugs are currently found only in the Americas, disease transmission is limited to this region. The majority of people infected live in South America, Central America, or Mexico.
[HI]5 Similarities
[/HI]Both diseases have an acute phase, which occurs upon infection, and a chronic phase, which develops years later. Because both diseases may not have symptoms for many years, people can be infected and not know it.
Both Chagas disease and HIV/AIDS can be acquired from a blood transfusion.
Both diseases can be passed from mother to child during pregnancy.
Both disproportionably affect people living in poverty, according to the authors of the PLoS paper.
Pass it on: Chagas disease shares some characteristics with HIVS/AIDS, but the conditions also have important differences.
