A blood-sucking kissing bug that can lead to a fatal infection is inching its way closer to the Hudson Valley.

The CDC confirmed a Triatoma sanguisuga, which is called a "kissing bug" because it likes to suck blood near a human's mouth, was found in Delaware.

The bug bit a Delaware girl in her face as she watched TV in her home, the CDC reported. Luckily the girl didn't get sick.

However, officials are warning the "kissing bug" transmits the fatal Chagas disease.

The deadly pest comes from South and Central America but has now been confirmed in a growing number of states in the United States and is on the doorsteps of New York.

The CDC confirms the bug has been spotted in all of the United States, besides the northern parts of the country.

Close to New York, the bug has been confirmed to be in Pennsylvania and has "potentially" been found in New Jersey, the CDC reports.

Complications of chronic Chagas disease may include heart rhythm abnormalities that can cause sudden death; a dilated heart that doesn’t pump blood well; and a dilated esophagus or colon, leading to difficulties with eating or passing stool, according to the CDC.

Other symptoms include fever, fatigue, body aches, headache, rash, loss of appetite, diarrhea, vomiting, mild enlargement of the liver or spleen, swollen glands, or swelling at the site of the bite.
