The new "crackle" swarms in the US kill cattle by draining their blood and chasing people



Worried about an earthquake in the Cascadia subduction zone? Worried about nuclear war? Worried about climate change?

Phhffft!

These potential disasters are nothing. If you really want nightmares, read on to find out what happens to North Carolina cows – and what that could mean to humans.

Asian longhorn ticks, sometimes referred to as "worm-eagles," as they can reproduce without mating, have killed and killed five cows in North Carolina this year-by getting rid of blood. Each cow was overwhelmed by hundreds of ticks.

"The official cause of death," writes the technology news site Ars Technica, "was acute anemia, which is typically associated with major bleeding."

These ticks are extremely aggressive. The New Jersey Health Investigators reported in 201

7 that they quickly climbed up their legs while they were examining a tick attack on a sheepskin. Common killing grounds for ticks are Russia and Asia, where they are known to transmit various serious diseases to humans. It is not known how or when they arrived in the USA. So far, the animals found in North America have transmitted no disease.

"The first case identified in the US came from West Virginia as a Whitetail Deer in August 2010," the Department of Agriculture and Consumer Services in North Carolina wrote in a warning to pet owners on 8 July. "Since then, 67 districts in the US have confirmed local Asian longhorn tick populations. Virginia has confirmed most counties with 24.

The state agency added, "The tick can be parthenogenetically reproduced (without a male), and a single fed female tick can produce a localized population.

Centers for Disease Control and Prevention indicates that "Asian longhorn ticks have been found on pets, farm animals, wildlife and humans".

In May, the first known case of an Asian longhorn tick biting a human in the USA occurred. This happened in the state of New York. "Subsequent field studies have confirmed that this tick was present in several geographical locations near the patient's home, even on well-kept lawns," wrote Clinical Infectious Diseases.

In the US, Asian longhorn ticks were found in Arkansas, Connecticut. Kentucky, Maryland, New Jersey, New York, North Carolina, Pennsylvania, Virginia, Tennessee and West Virginia.

The CDC recommends that people take precautionary measures against ticks. "And to investigate clothes and perform a" full body check "after being outdoors.
