A man from Yonkers, NY, was recognized as the first human being in the United States to be bitten by the Haemaphysalis longicornis According to the researchers, ticks, also known as horned Asian ticks, have revealed that 90 ticks have been found near the man's home.
Experts have recently expressed concern about the spread of the invasive tick species, which was first identified in the United States in 2017 and can transmit many human infections.
The 66-year-old man removed the tick from his leg in June 2018.
"Prior to [this], no human being in the United States had been bitten by this species of ticks, but it is difficult to be sure that human bites have not taken place before, because patients do not find or keep ticks who bit them, and when they do. , the option of identifying an expert by an entomologist may not be available ", Gary P. Wormser, MARYLAND, Head of Infectious Diseases Division of New York Medical College, and his colleagues wrote Clinical Infectious Diseases.
The researchers reported the first bite in the United States of a long-horned Asian tick, an invasive tick species that can carry many human pathogens..

"A recent badysis of human ticks around the world considers that H. longicornis parasite "frequent" humans. … If future introductions of this species of ticks were to take place and some of the introduced ticks were infected with [severe fever with thrombocytopenia virus]this could actually pose a public health problem. "
According to the case report, the man was asymptomatic and did not develop clinical illness, but his primary care physician had prescribed doxycycline because it was believed that the tick was Ixodes scapular, which spreads Lyme disease. He wore the tick at the Lyme Disease Diagnostic Center in Westchester County, New York. He was sent for testing and was identified as H. longicornis.
Tick sampling was conducted near the patient's house on July 2 and 9, in a nearby park on July 9 and 18 and on a nearby trail on July 10. A total of 90 ticks were collected, four near the house, 25 in the park and 61 on the trail, creating the first known collection of H. longicornis in the state of New York, according to the report.
Female H. longicornis Ticks can reproduce without mating, sometimes resulting in mbadive infestations with thousands of ticks.
"H. longicornis is a potentially devastating ectoparasite of domestic animals and a vector of both human and veterinary pathogens ", Bobbi S. Pritt, MD, MSc, Director of the Clinical Parasitology Laboratory at the Mayo Clinic, wrote in a related commentary.
"Despite intensive efforts of control and elimination, H. longicornis extended beyond its initial detection site and has now been detected in 10 states: Arkansas, Connecticut, Kentucky, Maryland, New Jersey, New York, North Carolina, Pennsylvania, Virginia, and West Virginia. While [Wormser and colleagues’] The report on a human bite is not surprising given the known behavior of this tick elsewhere, it clearly proves that this invasive tick continues to bite its host in its most recent place.
