Chagas Disease in the U.S.: Kissing Bugs and the Kissing Bug Threat Spreading Across States

Chagas disease, known as the deadly “kissing bug” disease, is now a rising health concern in the United States. A recent Centers for Disease Control and Prevention report shows the insect is no longer just a Latin American problem. Human cases have already been confirmed in at least eight states, most often in Texas. Experts warn the parasite is spreading faster than once thought.

The kissing bug, also called triatomine, is now reported in 32 U.S. states. The parasite it carries, called Trypanosoma cruzi, causes Chagas disease. It can silently infect people for years. In some cases, it can lead to deadly heart or digestive failure. Public health leaders say labeling the U.S. as “non-endemic” only delays awareness and action.

Kissing Bugs and How They Spread Chagas Disease

The kissing bug gets its name from its habit of biting near the face. After biting, the insect often leaves droppings. If bug waste touches a wound, eye, or mouth, the parasite can enter the body. This is how infection begins. According to the CDC, about 8 million people worldwide and 280,000 in the U.S. may already be infected. Many do not even know it.

Acute symptoms can appear soon after infection. These may include fever, body aches, rash, and a swollen eyelid called Romaña’s sign. Some people show no signs for years. But in the chronic phase, the disease can damage the heart, esophagus, and colon. Doctors say this is when the risk of death grows higher.

Researchers note that Chagas disease does not spread by casual contact. It cannot be passed like a cold. It also does not spread directly from one person to another. Instead, bites, contaminated food, or blood transfusions are the main risks.

Rising Risk and How to Stay Safe

Health officials stress there is no vaccine for Chagas disease. Prevention is the only defense. Simple steps like sealing windows, using insect repellent, and wearing skin-covering clothes can help. Homeowners are urged to keep wood piles, trash, and rocks away from living areas. This reduces the chance of insects nesting nearby.

Travelers are also advised to stay in well-built housing. Experts warn against eating raw fruits and vegetables in risky regions, since parasites can enter food. Reports also show dogs are often infected, raising public awareness as pets are diagnosed more often.

According to Reuters, doctors and scientists say more research is needed. They note that data on insect spread is still limited. But encounters with humans are on the rise, making awareness urgent. The disease may not be common, but it is no longer rare in the U.S.

Chagas disease is a hidden but serious threat. The kissing bug is moving into more states. Public health experts urge vigilance, awareness, and prevention.
