WBAL | SURRY COUNTY, NC. – The Centers for Disease Control is issuing a new warning about ticks after the reported deaths of five cows in North Carolina.
All of the cows’ deaths were linked to acute anemia caused by tick infestations in Surry County, WCNC reported.
WCNC reported that the ticks were tested, and officials identified them as Asian longhorned ticks, known to be aggressive biters.
“We now can find ticks in our lawns,” said Dr. Alan Tagey, from the Cleveland Clinic. “We can find them in the woods. We can find them where weeds are growing.”
Experts recommend routine checks for your livestock, pets and kids.
Ticks are tiny in stature, but doctors are preaching prevention because of the sizable problems they can cause, such as Rocky Mountain spotted fever or Lyme disease in some cases. Read more.
Emerging infectious disease carrier spreads; “can reproduce in large numbers”
Mayo Clinic Minute, July 9, 2019
A species of tick originating from Asia is spreading quickly across the Western Hemisphere, and it’s drawing concern from U.S. health officials — not only for the potential danger of spreading viruses and bacteria, but also because it was found on a well-manicured lawn rather than the typical tick environment of long grasses and bushes.
The Asian longhorned tick was initially found in the U.S. in 2017. And despite public health efforts. “… it did spread. It is now in 11 states,” says Dr. Bobbi Pritt, a Mayo Clinic parasitic diseases expert.
[As of June 24, 2019, longhorned ticks have been found in Arkansas, Connecticut, Kentucky, Maryland, North Carolina, New Jersey, New York, Pennsylvania, Tennessee, Virginia, and West Virginia. – CDC]
Similar in size to the average American wood tick, the Asian longhorned tick can reproduce in large numbers.

“So she can produce hundreds and hundreds of offspring that live on a single animal,” says Dr. Pritt. “And the blood loss from the feeding on that animal can be so great, the animal can die.”
It also will bite humans. And, in other countries, has transmitted viruses and bacteria that have made people seriously ill.
“So one virus in particular that we’d be quite worried about is one called ‘severe fever with thrombocytopenia syndrome virus,'” says Dr. Pritt.
[The CDC lists thrombocytopenia syndrome virus as an emerging infectious disease:
“Severe fever with thrombocytopenia syndrome (SFTS), a tickborne viral disease, has been identified in China, South Korea, and Japan since 2009. SFTSV is a tick-borne virus that can cause hemorrhagic fever.SFTS was confirmed in China in 2009 and then retrospectively reported in South Korea in 2012 and in western Japan in 2013. Most SFTSV infections occur through bites from Haemaphysalis longicornis ticks, although transmission can also occur through close contact with an infected patient.” Source.]
As of now, no harmful germs have been found in ticks collected in the U.S., but it might be only a matter of time.
And tick bite prevention is key. Use tick repellent outdoors, wear clothing that covers your arms and legs, tuck your pants into your socks, and remove any ticks from people or animals as soon as possible. Courtesy: Mayo Clinic News Network.
Asia’s Longhorned Tick Takes Its First Documented Bite In The U.S.
Fran Kritz, June 7, 2019
NPR – Tick bites man.
That’s not exactly news, but it is in the case of a particular tick that bit a particular man. The tick, native to Asia, is Haemaphysalis longicornis, also known as the longhorned tick. It was only recently discovered in North America.
And now, for the first time, there’s a record of a bite by the longhorned tick in the U.S.
The bite, which took place last year, is documented in a journal report published in late May in Clinical Infectious Diseases.
The tick’s victim, who lives in Westchester County, New York, has not become ill as a result of the bite. But health experts are keenly aware that in Asia, and in Australia and New Zealand, where the tick is found as well, it is known to spread pathogens that can be lethal to humans and animals.
One such pathogen is SFTS virus, a potentially fatal hemorrhagic fever. SFTS is not found in North America but is similar to the Heartland virus, which is present in North America and can be transmitted by ticks, according to Dr. Bobbi Pritt, director of the Clinical Parasitology Laboratory at the Mayo Clinic. So far there is no evidence that the longhorned tick carries this virus.
The longhorned tick was first formally detected in the U.S. on a sheep in New Jersey in 2017. No one knows exactly how the tick made it to North America, and tick experts say it’s possible that it arrived earlier than that.
As for the documentation of the first bite, Rick Ostfeld, senior scientist at the Cary Institute of Ecosystem Studies in New York State and a tick specialist, cautions that longhorned ticks have probably bitten humans in the U.S. before — but no one realized the bite came from a different species of tick.
And this species is definitely different from other ticks — in ways that are potentially worrisome to humans … Read more.
