A new invasive tick species capable of transferring a number of serious diseases spreads in the US, which is a threat to human and animal health, according to a pair of reports published on Thursday.
Y A colorful Asian ticket is the first multiple tick to reach the US in about 80 years. It is native to eastern China, Japan, Far East Russia and the Korean Peninsula and has now set up in Australia and New Zealand.
In August last year, we found 12 year olds of Ice animals in western New Jersey. Since then, there was a tick in Arkansas, Connecticut, Maryland, New York, North Carolina, Pennsylvania, Virginia and West Virginia. The species has been found on pets, livestock, wildlife and people. So far, however, there is no evidence that the tick has slipped pathogens to people, domestic animals or wildlife in the United States, according to a report by the Centers for Disease Control and Prevention.
But public health officials are worried about the potential Haemaphysalis longicornis to spread disease. In other parts of the world, there is a pile of livestock; Its bites can make people and animals seriously ill. In some parts of Australia and New Zealand, the ticks suck so much blood by dairy cows that cause milk to decrease by 25 percent, researchers have found.
In Asia, the tick contains a virus that causes human hemorrhagic fever and kills up to 30 percent of victims. Although that virus is not in the United States, it is closely associated with Heartland's virus, another life-threatening disease that hit the US in the United States . Health officials are particularly concerned about the ability to adjust to be a vector for that virus and other diseases that are ticked by a tick in the United States.
The tick "is possible to spread a large number of diseases," said Lyle Petersen, director of the Vector-Borne Disease Division CDC. "We do not really know if diseases will be spread by the tick in the United States and, if so, to what extent. But it is very important that we quickly identify this."
The female tick can also put hundreds of fertile eggs without maturing, "leading to multiple injuries to visitors," said the CDC report.
An illness of mosquitoes, tickers and feathers bites more than triple in the United States from 2004 to 2016, according to the CDC. The increase in the diseases carried by a vector has many basic causes: the expansion of travel and commerce, urbanization, population growth and increasing temperatures.
Heat and climate change temperatures make the environment more welcoming to tactics or mosquitoes that spread pathogens and increase season-time ticks, says Petersen.
Next week, officials from a number of federal agencies – including the CDC, the Department of Agriculture, the Environmental Protection Agency, the National Park and Defense Department Service – meet to develop a national cohesive strategy on for fighting the diseases that are transported by a vector.
"The problems are getting worse and worse," said Petersen, stating that all countries except Alaska were in breach of an increase in these diseases. "We're missing this battle."
Officials said they were trying to raise awareness among public health officers, healthcare workers and vets about the potential threat of this species. As well as the CDC report, the Petersen and CDC colleagues announced a companion paper in the Journal of Tropical Journal of Medicine and Hygiene which highlights the "significant gaps" in the capacity of public health systems to respond to & # 39 These r diseases.
There are many diseases that are spread by induced ticks. Also, there are no proven measures that can be graded to control many diseases that are transmitted by a vector transmitted by the stroke or deer legs that may at least spread seven human pathogen in the United States, including the bacteria that cause Lyme disease.
Officials do not know when or how long they arrived at the late ticket in the United States. Between August 2017 and September 2018, there were 53 reports of the tick in the United States. The state with the highest percentage of counties that have been in New Jersey (33 per cent), West Virginia (20 per cent) and Virginia (12 per cent), including Fairfax County, suburb D.C. Using retrospective analysis, scientists believe the assault occurred earlier.
Tadhgh Rainey, an entomologist at Hunterdon Health Division in New Jersey, came to find the ticks on August 1, 2017, when a woman who shed her Iceland sheep flocks arrived in the department with her & # 39 ; n think he's bees on his hands.
On the closer inspection, they turned out to be larval terms. And she was covered in them.
"She had them all over her clothes. We're talking over 1,000 tacks on her body," said Rainey after an interview. "They were a species that we never had to see from" "and so on." Rainey helped to change her clothes to the woman, and health officials put her pants in a freezer to kill the ticks.
As Rainey attempted to identify the species, the girl returned about two weeks later, this time with her favorite thicks for sheep. Rainey said he realized that there was nothing he had ever seen before and was going to visit a farm to see the animal over himself.
"I was huddled in ticks," he said. "They had been embedded over the sheep, thousands of them on their ears, too much to count."
Andrea Egizi, research scientist at the Monmouthshire Removal Disease Laboratory, at Rutgers University, said the tick using DNA analysis, and later confirmed by USDA scientists.
Rainey said the US probably liked a big animal. That part of the state has an active trade of horses and sheep abroad. The affected sheep had never traveled outside the country. "Or a person who went on a nature hike in New Zealand might have expired," he said.
Health department officials were able to kill all the tuckers on the sheep and eliminate the property of the woman. The deaf, named Hannah, died recently of old age, says Rainey. The woman's trousers health department has "she still does not want her pants."
