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.

(Am J Obstet Gynecol. 2017;216(1):34.e1–34.e5) The Zika virus epidemic raised many questions in relation to birth defects in infants born to mothers infected with Zika. This included whether the risk of adverse outcomes could be reduced after infection. During both the 2009 H1N1 pandemic and the 2014 to 2015 Ebola epidemic, there were missed opportunities to involve pregnant women in research to better understand poor neonatal outcomes or the effects of antiviral medications on pregnant women and neonates.
Florida health officials report state's 2nd case this year of the Zika virus transmitted by a local mosquito
Conclusions: The World Health Organization declared the end of the “Public Health Emergency of International Concern” in December 2016, but ZIKV and associated consequences remain a significant enduring public health challenge.
(Sanford-Burnham Prebys Medical Discovery Institute) California researchers have discovered that a medication used to prevent and treat malaria may also be effective for Zika virus. The drug, called chloroquine, has a long history of safe use during pregnancy, and is relatively inexpensive. The research was published today in Scientific Reports.
AbstractThe article Phylogenetic Insight into Zika and Emerging Viruses for a Perspective on Potential Hosts, written by Diana S. Weber, Karen A. Alroy, and Samuel M. Scheiner, was originally published Online First without open access.
Abstract We examine Zika virus (ZIKV) from an ecological perspective and with a focus on the Americas. We assess (1) the role of wildlife in ZIKV disease ecology, (2) how mosquito behavior and biology influence disease dynamics, and (3) how nontarget species and ecosystems may be impacted by vector control programs. Our review suggests that free-ranging, non-human primates may be involved in ZIKV transmission in the Old World; however, other wildlife species likely play a limited role in maintaining or transmitting ZIKV. In the Americas, a zoonotic cycle has not yet been definitively established. Understanding behaviors ...
We report the case of a patient, aged 58 years, from Rio de Janeiro, Brazil, who in 2013 developed an acute bilateral third cranial nerve palsy sparing the pupil. After extensive investigation, it was diagnosed as caused by chikungunya infection. The patient was treated with pulse therapy and after 5 months of the onset of the condition, the patient showed improvement. PMID: 29135313 [PubMed - as supplied by publisher]
(Cincinnati Children's Hospital Medical Center) Birth defects in babies born infected with Zika virus remain a major health concern. Now, scientists suggest the possibility that some women in high-risk Zika regions may already be protected and not know it. New research in PLOS Pathogens on Nov. 16, performed in mice, shows women who develop symptom-free Zika infections may be able to acquire immunity that would protect them from future infections and their offspring in a future pregnancy.
(PLOS) Protective antibodies from prior asymptomatic Zika infection defend against reinfection during pregnancy in mice, according to new research published in PLOS Pathogens.
(German Center for Infection Research) Scientists have elucidated the Zika burden in a Brazilian metropolis. Their data indicate: the outbreak may be coming to an end and further outbreaks in the region seem unlikely. The study has also provided new evidence supporting the link between Zika infection during pregnancy and malformations in newborns. A third finding is important with regard to intervention measures: Zika virus infection predominantly affects poor regions.
