Chagas Disease Reaches Epidemic Levels in the US: What You Need to Know
The Centers for Disease Control and Prevention (CDC) reports that Chagas disease, a potentially life-threatening illness spread by “kissing bugs,” has reached epidemic levels in the US. With human cases documented in at least eight states, health officials are sounding the alarm, warning that the actual number of cases may be significantly higher due to inadequate surveillance.
According to the World Health Organization (WHO), Chagas disease is transmitted through contact with the excretion of the Trypanosoma cruzi parasite, which is found in the feces of infected “kissing bugs.” These bugs, also known as triatomines, typically hide during the day and become active at night, feeding on animal and human blood. They often bite exposed areas of skin, such as the face, and defecate or urinate close to the bite, allowing the parasite to enter the body when the person instinctively smears the bug’s feces or urine into the bite, other skin breaks, the eyes, or the mouth.

How Chagas Disease Spreads
Chagas disease can also be spread through blood transfusions, organ transplants, and from mother to child during pregnancy. Pets and wildlife are also highly susceptible to the disease, making it challenging to contain transmission once the parasite becomes established in an area.
Health officials emphasize that early treatment can cure the disease’s symptoms, but without proper diagnosis and treatment, cardiac and neurological problems can develop. The WHO estimates that over 7 million people worldwide are infected, resulting in around 10,000 deaths annually.

Prevention and Treatment
To prevent the spread of Chagas disease, health officials recommend sealing gaps where bugs might enter a structure and treating locations where the insects might hide. The US Food and Drug Administration also tests potential blood donors for the parasite that causes the disease.
While there is no known vaccine for Chagas, doctors rely on antiparasitic drugs to help ease symptoms. Most infections usually go undetected, but some victims may develop a fever and swelling, which can occur years after the initial infection.
