Parasitic insects known as “kissing bugs,” identifiable by their small dark bodies and orange and red stripes, were once seen primarily in rural South America.
However, recent research has shown that these insects are now present in 29 states across the United States, raising significant concern among researchers.
These bugs are known to transmit Chagas disease, often referred to as “kissing bug disease,” through contact with their feces.
This transmission can occur when feces is accidentally rubbed into open wounds, the eyes, or the mouth, which is how the disease gets its name, according to the Centers for Disease Control and Prevention (CDC).
Initially presenting with mild symptoms, Chagas disease can lead to severe complications such as heart disease and stroke if left undiagnosed.
Texas A&M University researchers estimate there may be over 1 million cases of Chagas disease in the United States.
Since 2013, there have been approximately 10,000 reports of kissing bugs in the country, including in neighboring New Jersey and Pennsylvania.
The study revealed that slightly more than half of the captured bugs were carriers of the Chagas parasite, which can infect humans.
While there have been no documented cases of Chagas disease in New York, the CDC has noted the potential for kissing bugs to spread into the state, though they have not yet been detected.
Ecologist Jose Ramirez-Garofalo, president of Protectors of Pine Oak Woods, expressed concerns that it may only be a matter of time before they arrive.
He emphasized the insects’ proficiency at flying, which aids their ability to travel long distances.
Ramirez-Garofalo also cautioned Staten Islanders against killing insects they suspect may be kissing bugs, as many species that are indigenous to the area resemble them closely.
Historically, these bugs have existed across Latin America for hundreds of years, and reports of Chagas disease have been present in southern U.S. states for decades.
The alarming nature of this spread has led researchers to advocate for Chagas disease to be labeled as endemic within the United States.
Such classification would ensure increased awareness and funding for both research and treatment initiatives, according to a CDC-supported study by researchers at the University of Florida and Texas A&M.
The researchers identified consistent cases of Chagas disease in eight states: Texas, California, Arizona, Louisiana, Tennessee, Missouri, Mississippi, and Arkansas.
The CDC has noted infected kissing bugs in 32 states, primarily within the southern region of the country.
Chagas disease, often referred to as the “silent killer,” can remain dormant for years, leading to severe cardiac complications, including heart failure, stroke, and even sudden death, as reported by the CDC.
Acute symptoms, which may include swollen limbs or eyes, often occur shortly after infection but can be mild or even absent entirely.
Common early symptoms include fever, fatigue, body aches, headaches, rash, diarrhea, or eyelid swelling, according to the CDC.
In the field of epidemiology, an infection is considered endemic when it remains consistently present within a specific region or population.
Dr. Norman Beatty, an epidemiologist and expert on Chagas, stated that while this disease has long affected Latin Americans, it is also a growing concern within the United States.
Recognizing the endemic nature of Chagas disease will be crucial for initiating effective local, state, and national strategies to combat this neglected illness, which has not been limited to tropical regions.
Given that early symptoms can easily be missed, timely treatment is critical and can significantly impact health outcomes, the CDC warns.
Infection with the T. cruzi parasite, responsible for Chagas disease, can occur through various means such as contaminated food, drink, blood transfusions, or organ transplants, though these routes are rare.
The study conducted by the University of Florida and Texas A&M posits that failing to classify the U.S. as non-Chagas disease-endemic may lead to continual low awareness and underreporting of cases.
Proper classification could enhance surveillance, research, and public health responses to this growing health issue.
For travelers in regions with high populations of kissing bugs, the CDC recommends several protective measures including staying in well-constructed accommodations, utilizing screened-in or air-conditioned rooms, and sleeping under insecticide-treated bed nets.
They also advise wearing clothing that covers the skin and using insect repellent on exposed areas.
Additionally, travelers are cautioned to avoid consuming salads, raw vegetables, unpeeled fruits, and unpasteurized fruit juices in these areas.
