Bed bugs may be a potential new cause of tropical disease in the United States

Latest infectious disease news

Monday, November 17, 2014 (HealthDay News)-Until recently, insect-borne Chagas disease was found primarily in Latin and South America, but has spread to the United States in the last few years.

A potentially fatal disease is usually transmitted through the bite of a “triatoma rubrofa” that eats the human face at night. And now, new research suggests that common bed bugs may also be carriers.

“We have shown that bed bugs can acquire and infect parasites. The next step is to determine if they are important players or important players in the epidemiology of Chagas disease. “The study’s senior author, Michael Levy, assistant professor, Department of Biostatistics and Epidemiology, University of Pennsylvania’s School of Perelman Medicine, said in a university news release.

According to background information from researchers, Chagas disease affects 6 to 8 million people worldwide and kills about 50,000 people annually, making it one of the most common and dangerous diseases in Latin America. is.Diseases caused by microscopic parasites Cruise TrypanosomaResearchers have explained that although it can progress for years without symptoms, it can attack the heart and cause heart failure.

“We’re finding new evidence of a locally acquired human infection in Texas,” said Melissa Nolan Garcia, a researcher at Baylor College of Medicine in Houston. HealthDay Early this month. Her team reported the findings at the annual meeting of the American Society of Tropical Medicine and Hygiene in New Orleans.

It has long been known that “triatoma rubrofa” can infect people through feces with Chagas disease, but bed bugs were thought to be disease-free.

However, in a series of experiments, Levy’s team discovered a parasite that causes Chagas disease. it can It goes back and forth between the mouse and the bed bug.

“There are several reasons to worry. Triatoma rubrofas come into contact with people more often than triatoma rubrofas and give them ample opportunity to infect parasites, often in homes where parasites are endemic. Understand what you can mitigate, “Levy added.

The parasites responsible for Chagas disease appear especially in the gut of bed bugs, added Renzo Salazar, a biologist at the University of Perana Cajetano Eledia in Lima, Peru, who co-authored the study.

“I’ve never seen insects have so many parasites. I expected a scenario with very few infections, but many parasites were found. They replicate very well in the bedbug’s intestines.” Salazar said in a news release.

According to the US Centers for Disease Control and Prevention, the number of people infected with the parasites that cause Chagas disease is increasing in the United States, and now stands at about 300,000.

“The triatoma rubrofa here aren’t brought home as often as the more dangerous species in Latin America,” Levy said. But “I’m more worried about the role of bed bugs,” he said. “They are already here-our home, our bed, and a lot. What we have found is how I think about infection, and where Chagas disease can come next. I threw a wrench at. “

The findings will be displayed online on November 17th. American Journal of Tropical Medicine and Hygiene..
