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.

Conclusions/SignificanceOur model generates country level exportation and importation risk profiles over the course of the epidemic and provides quantitative estimates for the likelihood of introduced Zika virus resulting in local transmission, between all origin-destination travel pairs in the Americas. Our findings indicate that local vector control, rather than travel restrictions, will be more effective at reducing the risks of Zika virus transmission and establishment. Moreover, the inverse relationship between Zika virus transmission and GDP suggests that Zika cases are more likely to occur in regions where people ca...

by Peter J. Hotez Within the last five years, the State of Texas has experienced either transmission or outbreaks of Ebola, chikungunya, West Nile, and Zika virus infections. Autochthonous transmission of neglected parasitic and bacterial diseases has also become increasingly reported. The rise of such emerging and neglected tropical diseases (NTDs) has not occurred by accident but instead reflects rapidly evolving changes and shifts in a “new” Texas beset by modern and globalizing forces that include rapid expansions in population together with urbanization and human migrations, altered transportation pa tter...

This report highlights potential drawbacks of using IgG serology for diagnosis of flavivirus infections in endemic regions. The low viremia detected during the early phase of this case resulted in low mosquito infectivity rates, suggesting the possibility of ZIKV transmission prior to clinical onset. The report also emphasizes the challenges of public health interventions for Zika fever and the importance of sustaining a low vector population to reduce the risk of arbovirus transmission in vulnerable regions.

Purpose of review Zika virus (ZIKV), a mosquito-borne flavivirus, has gained recognition over the past few years as an important new cause of congenital infection. As a result, it is critical that pediatricians understand its epidemiology, clinical presentation, clinical sequelae, and management. Recent findings The recent ZIKV epidemiology, clinical presentation of acute infection in children and complications, perinatal infection, and congenital infection will be summarized in this ZIKV review. This will be followed by a brief summary on ZIKV diagnosis, management, treatment, and prevention. Summary The field of ...

Purpose of review Zika virus has recently emerged from an obscure mosquito-borne pathogen to an international public health concern. It is the first viral agent newly demonstrated to cause birth defects in several decades, and it is the only arbovirus now known to be transmitted sexually. The purpose of this review is to provide an overview of current understanding of sexual transmission of Zika virus and its possible clinical and public health consequences. Recent findings Sexual transmission of Zika virus has been reported from at least 13 countries without simultaneous mosquito-borne transmission; it is undoubtedly...

University of Cambridge. 11/29/2017 This one-hour, 13-minute lecture from the Centre for the Study of Existential Risk discusses how mosquito-borne zoonoses, such as West Nile virus and Zika virus, exemplify the importance of implementing a One Health approach to interdisciplinary threats. One Health is the concept that human, animal, and environmental health are linked. The speaker details how this concept can serve as a framework to analyze the interrelationships between food security, the environment, and emerging diseases. (Video or Multimedia)
