Tuck holds a history of a long time in every disturbing cutting

When you think that of tickets, you could have an image of a scary marsh Little parasites, which you walk across the weekend or walk within the park at noon.

Your fears are well established. There are diseases brought on by Tuck The most prevailing vector diseases – People who move through living organisms – within the United States. Each tick eats on many animals in his life, absorbs viruses and bacteria along the best way, and moves it forward with the following bite. Some of those viruses and bacteria are harmful to humans, which causes diseases that could be weak and sometimes deadly with none treatment. VineyardFor, for, for,. Babisosis And Catchy shell.

But every little bit of this rotation involves, unwanted insects are also a The result of the history of social, environmental and pandemic diseases.

In many cases, human measures have long been the rationale why these diseases are brought on by taking such a big scale today. And that’s the reason tickets make interest Environmental historians like me.

Turning the hazards of tuck by changing the forests

During the 18th and nineteenth century, settlers Cleaned more than half Crossing the northeastern United States, cutting forests, forests for wood and can make the best way for fields, cities and mining works. With the cleansing of the land on a big scale, all types of wildlife decreased rapidly. Hunters like bears and wolves were expelled like deer.

When farming moved towards the west, the northeastern trees began to acknowledge the environmental and economic value of the northeastern trees, and so they Looted millions of acres of land in the forest.

Woods is a trend. Plants like deer returned, but once the highest hunters who maintain their population didn’t achieve this.

As a result, Deer's population By carrying, the germs that cause lime disease, increased rapidly. And got here with the deer The deer stick ().. When a tuck is eaten on an infected deer, it will probably take bacteria. The tick will not be damaged, but it will probably bring bacteria to its next victim. In humans, lime disease could cause fever and fatigue, and If not treated It can affect the nervous system.

East America became a worldwide hot spot for a lime disease that began across the Seventies. Lime disease In 2023 affected more than 89,000 Americans, and possibly much more.

California people went to the Tuck area

For centuries, the changing patterns of human settlements and the politics of land use have shaped the role of ailments brought on by tick and tick of their environment.

Recently. , Humans have made it easier to advertise and spread pieces in the course of us.

In California, the northern inner coast and the Santa Cruz Mountain boundaries which might be present in the north and south of San Francisco were never clear, and hunters just like the mountain lion and coyots are still present. But there’s a contest for accommodation Pushed human settlement In the depth The area of ​​the city north, south and eastChanging the Tuck Environment there.

Although Western black feet tick () is crowded in large reservations of the jungle, the lime producing bacterium is definitely more common Small, green patch patch of green. In these isolated patches, rats and other tick hosts could be shielded from large hunters, developing development, which requires more residence to maneuver freely. But loneliness and low diversity also mean that infections spread more easily within the tuck host population.

People construct isolated houses within the hills slightly than large, connected developments. Since the world of ​​Silicon Valley, south of San Francisco, spreads outward, the type of this checker board of settlement has scattered natural landscape, Creating a difficult risk of health public.

Less host, more firmly packed, often proportional, and thus more dangerous tickets are more affected.

In these limits, six county, throughout and San Francisco, is calculated 44 % of diseases arising from Tuck recorded in California.

Texas cattle fields lesson

Domestic livestock has also pursued the chance of disease -picked out through tickets.

In 1892, at a gathering of livestock farming on the stock razor convention in the town of Austin, Texas, Dr. Ba Rogers introduced a brand new theory that was behind the recent devastating plague of Texas cattle fever. The disease arrived with cattle imported from the West Indies and Mexico within the 1600s, and it was taking Heavy tools on the herd of cattle. But how the disease spread to recent victims.

Daniel's Texas Medical Journal editors found the concept of ​​illness spread Laughed to laughing and assumingPublishing a sarcastic as a “preliminary copy” of the upcoming report on this topic.

It is believed that Tuck's “fluid secretion, it’s poison that causes a fever … [and the tick] Known to chew tobacco, as all other texions do, the secretion might be the tobacco juice.

Fortunately for the fields, not to say the cows, the US Department of Agriculture supported Rogers. Its cattle fever tuck program, began in 1906, controlled the outbreak of cattle fever Where and when the cattle should cross the dense areas, restrict it.

Up to 1938, The government had established a Singh zone It prolonged 580 miles along the US Mexico border within the southern Texas brush country, 580 miles, in favor of cattletime.

This revolutionary use of natural space as a health tool helped Eliminated practically Until 1943, livestock fever from 14 southern states.

Tickets are their environment products

When it involves tuck -born diseases world wide, location is essential.

Take the Mediterranean and Asia Hunter Tuck. As a minor, or aposer, these ticks eat small forest animals reminiscent of mice, rabbits and rotating, but as an adult they like livestock cattle.

For centuries, this tick was occasionally trouble for the Middle East nomadic shepherds. But within the 1850s, the Ottoman Empire passed the principles Forcing the nomadic tribes to become a settler instead of. Non -claimant lands, Especially on the forest edges of StepieSettlements were offered, which created ideal conditions for the pieces of hunter.

As a result, what’s the farmer in today's day Turkey saw an increase in tuck diseasesIncluding a virus that causes creamin Congo hemorrhage fever, A potentially fatal condition.

This summer might be very high to demand sympathy for any tick you meet. Eventually they’re bleeding.

Nevertheless, it’s value remembering that the misconduct of the tick will not be his own mistake. Tickets are the products of their environment, and humans have played many roles in turning them into harmful parasites that we seek today.
