Texas Has Called in the Air Force to Fight Post-Flood Mosquitoes

The U.S. Air Force has deployed an aircraft unit to Texas tackle swarms of mosquitos that have proliferated in coastal regions after Hurricane Harvey caused severe flooding. Reuters reports that U.S. Air Force C-130 cargo planes had sprayed insecticides over an area amounting to about 1.85 million acres across three eastern Texas counties. Insecticide spraying trucks have also been dispatched nightly in afflicted areas of Harris County — which encompasses Houston — since Sept. 4. According to Reuters, the Air Force program will be extended further across Texas to lower the risk of waterborne diseases such as the West Nile and Zika viruses, which can be transmitted through mosquito bites. C-130s were similarly used to control mosquito populations the wake of hurricanes Katrina, Rita and Gustav. Although few of the post-flood mosquitos are the disease-carrying variety, swarms of them can still inhibit relief efforts, local health officials say. Residents in affected areas have reportedly been advised to throw away standing water, use repellent, and cover exposed skin.

(Washington University School of Medicine) The same countries hard hit by Zika virus -- which can cause brain damage in babies infected before birth -- are also home to dengue virus. Washington University School of Medicine in St. Louis researchers report that they have found an antibody that protects against both viruses. These findings, in mice, could be a step towards an antibody-based preventative drug to protect fetuses from brain damage, while also protecting their mothers from both Zika and dengue disease.

Patient Presentation A 5-month-old male came to clinic for his health supervision visit and followup from his neonatal intensive care stay. He was born prematurely at 28 weeks gestation and his stay was complicated by a right sided Grade III intraventricular hemorrhage, a left-sided Grade IV intraventricular hemorrhage, neonatal seizures, respiratory distress and bronchopulmonary dysplasia, retinopathy of prematurity, acute kidney injury that had resolved, possible necrotizing enterocolitis incidents x 2, and herpes simplex encephalitis. He was on home oxygen, a nasogastric feeding tube because of aspiration risk and mult...

Currently, the laboratory diagnosis of Zika virus (ZIKV) infection is primarily through the detection of ZIKV RNA or antibodies against ZIKV proteins. The detection of viral RNA is highly sensitive and specific, but periods of viremia and viruria are brief, limiting the utility of ZIKV RNA assays. Instead, most ZIKV infections are diagnosed serologically, using an IgM antibody capture enzyme-linked immunosorbent assay (MAC-ELISA) for screening, followed by a confirmatory plaque reduction neutralization test (PRNT). Typical turnaround times vary, due to assay incubation periods and a lack of clinical laboratories performing...

This study describes an assay where the neutralization endpoint is measured by real-time PCR, providing results within 72 h. It demonstrated 100% sensitivity (24/24 ZKV and 15/15 DENV) and 100% specificity (11/11 specimens) when testing well-characterized sera. In addition, the assay was able to determine the correct DENV serotype in 91.7% of cases. The high sensitivity and specificity of the real-time PCR neutralization assay makes it suitable to use as a confirmatory test for sera that are reactive in commercial IgM/IgG enzyme immunoassays. Results are objective and the PCR-based measurement of the neutralization endpoin...

Centers for Disease Control and Prevention. 09/20/2017 This updated resource (2017) provides two maps of the estimated range of Aedes albopictus and Aedes aegypti mosquitoes in the United States in 2017. Aedes aegypti mosquitoes are more likely to spread Zika, dengue, chikungunya, and other viruses than other types of mosquitoes such as Aedes albopictus mosquitoes. The Web page also provides information about these mosquitoes, outbreaks spread by mosquitoes, and how to be protected from Zika and other viruses spread by mosquitoes. (Text)
