Inside Texas’s Grand Laboratory of Dangerous Mosquitos

Introduction:
(Vox) Austin, Texas — Under a microscope, a mosquito can look stunning. Their blue-green iridescent scales, purple bands, and attractive spotted wings shimmer — dazzling enough to forget, for a moment, the insect lives to take a sip of your blood.
Mosquitoes range in size, from smaller than your pinky fingernail to a commanding presence in your palm, but it takes a skilled eye and a steady hand to sort the most dangerous species.
At the Arbovirus-Entomology Laboratory of the Texas Department of State Health Services, getting a close-up look is a key step in an active statewide effort to keep vector-borne diseases at bay — and alert the rest of the country when a major outbreak is looming.
The US has proved successful in driving away some of the most common mosquito-borne diseases, like malaria and yellow fever, during the 20th century. With less worries about insect-borne illnesses, there are few local and state health agencies in the US investing in active efforts to find and eliminate dangerous insects. Now, these old diseases are starting to creep back in, and new ones are lurking in stagnant puddles, garbage dumps, and culverts. The Centers for Disease Control and Prevention report that the rates of infections spread by animals has more than doubled over the past 20 years. Yet, the picture of these illnesses across the US is spotty at best, and they are likely far more prevalent than we may realize.
However, Texas has been looking out for mosquitoes since 1954, and it’s still a priority. “Texas and Florida are the most vulnerable. … A lot of times, we’re the ones that see the first human cases of emerging diseases because of our climate, the vectors that we have, and the population levels,” said Bethany Bolling, who manages the zoonotic virology group at the Texas state health office. “We have active programs throughout Texas that are weekly collecting mosquitoes. We’re monitoring the population levels. We monitor the species, where they are. And then we’re also looking for pathogens.” The state of Texas spends $755,000 per year on its arbovirus surveillance program and employs seven molecular biologists on the team.
In addition to a fairly detailed discussion of mosquitos, the article briefly mentions the West Nile virus, dengue outbreaks, Chikungunya, and malaria. Trump administration budget cuts are also discussed.
