MICHIGAN — The treacherous “kissing bug” has made its way far north in the United States, threatening human and pet health.
The deadly “kissing bug” has been confirmed in dozens of U.S. states, including Michigan, the federal Centers for Disease Control and Prevention said. Chagas disease, as it’s officially known, earned the moniker because the triatomine bugs that transmit it typically bite people in the face.
The CDC said in September the kissing bug was making its way north from South and Central America. If Chagas disease is left untreated, the infection is lifelong and can be life-threatening, the agency said. Most infected people don’t experience symptoms, which can include fever, fatigue, aches, headache, rash and swelling at the site of transmission. But in severe cases, Chagas disease can lead to stroke or heart failure.
Currently, about 300,000 people in the United States and 8 million people worldwide are living with the disease, and researchers expect more U.S. infections could occur with climate change.
Kissing bug infections can also be transmitted from mother-to-baby, through contaminated blood products and organ transplants, and, more rarely, during laboratory accidents or through contaminated food or drink. In many countries where the disease is common, donated blood is screened for the disease.
Through found primarily in the southern half of the United States, the kissing bug bit a Delaware girl in 2018, the CDC confirmed last week. The girl was bitten in the face while watching television in her bedroom in the family’s home near a wooded area. The family had not recently traveled outside of their local area, which the CDC said was evidence the kissing bug is in the state.
The girl did not get sick from the kissing bug, according to news reports.

What To Do To Protect Yourself
The CDC says people can protect themselves against the kissing bug in several ways:
Seal cracks around the house;
Don’t install yard lights near the house, because they can attract bugs;
Allow pets to sleep indoors at night;
Clear brush or rock piles near the house;
Use screens on windows;
Keep the home and outdoor pet areas clean.
People who find an insect they think may be a kissing bug should place it unsquashed in a container and take it to their local health department or university for identification, and then thoroughly clean the area where it was found with a solution that includes one part bleach to nine parts water.
The kissing bug can also make pets sick. Researchers with Texas A&M University’s Agriculture and Life Sciences Department said the parasite can infect dogs with severe heart disease, though many don’t show any symptoms. The researchers said complications are typically related to the age of the dog, the activity level of the dog and the genetic strain of the parasite.
There is currently no vaccination to protect humans and dogs from Chagas disease.
