Chagas disease spreading in 32 US states through 'kissing bug' parasite: Essential information about this deadly illness

In the United States, a previously uncommon parasitic illness known as Chagas disease is gaining attention. The disease, caused by the Trypanosoma cruzi parasite, is transmitted by blood-feeding insects called kissing bugs, also known as triatomine insects.

These insects, which often bite around the mouth and eyes, have expanded their habitat into more US states due to climate warming. This expansion has resulted in an increase in the number of Chagas disease cases, particularly in southern states like Texas and California.

Chagas disease has a two-phase structure: acute and chronic. During the acute phase, symptoms may include fever, headache, swollen lymph nodes, muscle pain, and distinctive eyelid swelling known as Romana's sign. However, many people may not exhibit any symptoms during this phase, making the disease difficult to detect.

In the chronic phase, the parasite can cause significant damage to the heart, digestive system, and nervous system. Heart disease, digestive disorders, nervous system damage, and sudden death are possible outcomes in this phase. Up to one-third of patients with Chagas disease develop life-threatening cardiac complications, while around 1 in 10 suffer severe digestive disorders.

The World Health Organization estimates that more than seven million people are infected with Chagas disease globally, with over 10,000 deaths annually. In the US, an estimated 300,000 people may be infected, with many unaware that they have the disease.

Infection occurs when bug feces carrying the parasite enter the body through a wound or when rubbed accidentally into the eyes or mouth. Preventative measures include sealing cracks in houses, installing screens in windows, using nets treated with insecticides, and attempting to minimize habitats for bugs surrounding homes.

While the disease usually cannot be cured in the chronic phase, medications like Benznidazole and Nifurtimox can effectively treat Chagas disease during the acute phase. Dr. Norman Beatty, an epidemiologist, has stated that the US is only beginning to understand locally acquired cases of Chagas disease and that it is a neglected tropical disease that can be deadly.

Chagas disease has been confirmed in eight US states and is suspected in another 32 states, primarily in the southwestern states and California. As the disease continues to spread, it is crucial for public health officials to increase awareness and implement preventative measures to protect the public.
