The disease-spreading asian-tiger mosquito is here — science of us

A number of years ago, at just about this time of year, my family was enjoying a pleasant alfresco dinner in our Brooklyn backyard when a squad of marauding mosquitoes crashed the party. Gas jewelry These were unusually shrewd and persistent critters, targeting our ankles and the backs of our necks, hovering just out of reach of our swats and slaps. Electricity year 6 They were ferocious biters, too. Electricity dance moms But when one landed on my forearm, I paused to admire this nefariously beautiful creation of evolution: She was engineered to be a sleek hypodermic needle with wings, and her sole purpose was to siphon off, like a gas bandit, a bit of blood, which she needs in order to lay her eggs.

Only a mosquito nerd would get jazzed by insect markings during a backyard blood draw. Shell gas credit card 5 But it wasn’t that long ago, in ecosystem time, that the Asian tiger first turned up in the United States. Grade 9 electricity test A couple of mosquito-control officers in Houston spotted the mosquitoes (the official name is Aedes albopictus) in a port area of Houston, where the insects had presumably hitched a ride inside some used tires imported from Asia. Quadcopter gas motor Experts now consider it the most invasive mosquito in the world.

This immigration story is important for three reasons. Electricity 101 video One, since that day in August 1985, the Asian tiger has spread to at least 37 states in the U.S., including New York, Pennsylvania, and virtually all of New Jersey, in part because its eggs can survive northern winters. 3 gases Two, even battle-­hardened insect-control officials noticed something special about this mosquito: It is a very aggressive biter. Electricity generation by source by country And three, it is the only resident mosquito in the New York area, as far as anyone knows, that can transmit many of the “exotic” tropical viruses knocking on our door, including Zika.

Whether Zika is here to stay is another matter. Electricity tower vector As of May 25, New York City Health Department officials had reported 109 cases, including 17 women who were pregnant at the time of diagnosis and whose fetuses are thus at risk for developmental abnormalities, including small brain size (microcephaly). Electricity sound effect mp3 free download All those cases, however, were “imported.” People with the disease contracted it outside the U.S. Electricity office and showed up here already infected. Static electricity human body What public-health officials don’t know — and can’t predict — is whether the Asian tiger mosquito will spread Zika in New York City, in what they call a “local-transmission event.” “We think it’s possible,” says Dr. Gasco abu dhabi salary Jay Varma, the deputy health commissioner for disease control, “but not likely.”

The reason Varma believes local transmission is unlikely is that the exotic viruses similar to Zika have never gained a foothold in New York City. Electricity production in north korea Despite a recent chikungunya epidemic overseas, he says, “we have never once had a locally transmitted case.” In a little-known episode in 2013, however, Suffolk County health officials reported that a case of dengue fever on Long Island was locally transmitted — meaning someone on Long Island had the disease and an “American-based” mosquito passed it on. Gas variables pogil answers extension questions The Asian tiger was almost certainly the culprit. V gas station “We know it can happen,” says McAllister. 101 gas station “We just don’t know how likely it is to happen.”

McAllister says a “perfect storm kind of situation” has to arise for transmission of a tropical virus to occur so far from the tropics. Electricity quotes by benjamin franklin A mosquito has to bite somebody with a high level of virus in his blood; the virus has to incubate in the mosquito’s gut for about seven days after its “blood meal”; the same mosquito has to bite another person, so that the virus can be passed along. Gas meter reading Lowering the odds even more: The Asian tiger isn’t a picky eater. Gas 69 It would be as happy biting a squirrel or your dog as you (the mosquito driving the epidemic in Brazil, by contrast, prefers to bite humans, lives indoors with them, and has the habit of taking small, frequent blood meals, which facilitates the spread of disease).

No one thinks a major, Brazil-like outbreak is likely here, but isolated cases may become part of the local ecosystem. Gaston y la agrupacion santa fe Epidemiology is often about low-probability events superimposed on very big numbers: the number of mosquitoes out at any given time of year, the number of travelers from endemic areas, the amount of virus in their blood. Gas in dogs stomach Traffic between New York and the region where Zika is being transmitted peaks between May and August, according to the Port Authority. Gas welder job description The density of New York’s population, the presence of Aedes albopictus, and the number of potentially infected travelers lead McAllister to believe that, sooner or later, local transmission of Zika is a distinct possibility.

Perhaps the larger point is not about Zika at all, but about the Asian tiger mosquito. R gas constant Public-health officials know that it is effective at spreading many diseases. Electricity recruitment 2015 A 2007 Zika outbreak in Gabon was driven by Asian tigers, as was a chikungunya epidemic in Northern Italy. Gas stoichiometry As Rochlin says, “It can transmit pretty much everything.” And there’s been a dramatic increase in these types of illnesses. Power in costa rica “We’re seeing more frequent problems,” says the CDC’s McAllister. Gas prices under a dollar “We used to see a big mosquito-borne outbreak every ten years. Gas after eating fruit Last year it was chikungunya. Gas density formula This year it’s Zika. Z gas ensenada telefono And there’s probably something else that’s coming along as well. Electricity distribution vs transmission We just don’t know what it is.”

If this sounds a little alarmist, let’s return to that questionable claim in the mayor’s press release. Quadcopter gas engine It is true, in the modern sense, that Aedes aegypti “has never been found” in New York City. 4 other gases in the atmosphere But that is a historically — one is tempted to say fatally — inaccurate assertion. Grade 6 electricity experiments The informal name for Aedes aegypti is the “yellow-fever mosquito,” and it sparked at least 19 significant epidemics in New York City in the 18 th and early-19 th centuries, sailing into town in water barrels aboard slave ships and commercial vessels. Electricity notes class 10 pdf Those mosquitoes couldn’t survive a northern winter, but they hung around long enough to cause thousands of deaths in New York, Philadelphia, Baltimore, Boston, and other cities up and down the East Coast. Gas mask bong review This year’s Asian tigers are poised to emerge. Gas variables pogil Larvae have been detected on Long Island, and the blood-seeking females typically appear at the end of May.
