New framework helps gauge impact of mosquito control programs

(PLOS) Effective methods of controlling mosquito populations are needed to help lower the worldwide burden of mosquito-borne diseases including Zika, chikungunya, and dengue. Now, researchers reporting in PLOS Neglected Tropical Diseases have described a new statistical framework that can be used to assess mosquito control programs over broad time and space scales.

Barbosa, Licarion Pinto, Mário César Ugulino de Araújo, Márcio José Coelho PontesABSTRACTAedes aegypti mosquitoes are vectors of diseases such as dengue, chikungunya, zika and yellow fever. With the increase in the incidence of these diseases the population has resorted to the use of repellents searching to protect themselves from mosquito attack. The Brazilian market offers a wide variety of products with different active principles in varying levels of concentration, tim...

Conclusions/significanceOur study shows that exposure to bites ofAe.albopictus orAe.aegypti evokes in mice species-specific IgG responses to al34k2 or ae34k2, respectively. Deeper understanding of duration of antibody response and validation in natural conditions of human exposure toAedes mosquitoes are certainly needed. However, our findings point to the al34k2 salivary protein as a promising potential candidate for the development of immunoassays to evaluate human exposure toAe.albopictus. This would be a step forward in the establishment of a serological toolbox for the simultaneous assessment of human exposure toAedes ...

Conclusions and significanceAlthough IRM should be a fixture of all vector control programs, it is currently often absent from the strategic plans to control mosquito-borne diseases, especially arboviruses. Experiences from other public health disease vectors and agricultural pests underscore the need for urgent action in implementing IRM for invasiveAedes mosquitoes. Based on a plan developed for malaria vectors, here we propose some key activities to establish a global plan for IRM inAedes spp.

by Andrew J. Monaghan, Rebecca J. Eisen, Lars Eisen, Janet McAllister, Harry M. Savage, John-Paul Mutebi, Michael A. JohanssonAedes (Stegomyia) aegypti (L.) andAe.(Stegomyia) albopictus (Skuse) mosquitoes can transmit dengue, chikungunya, yellow fever, and Zika viruses. Limited surveillance has led to uncertainty regarding the geographic ranges of these vectors globally, and particularly in regions at the present-day margins of habitat suitability such as the contiguous United States. Empirical habitat suitability models based on environmental conditions can augment surveillance gaps to describe the estimated potential spe...

This 60-page manual provides technical guidelines for the strategic use of indoor residual spraying for Aedes aegypti mosquito control (IRS-Aedes) in urban areas, and compiles and standardizes the criteria, instruments, technical parameters, and equipment, as well as the application technique, for strategic integration of IRS-Aedes in Aedes aegypti control programs. Given the absence of a specific treatment and vaccines against dengue, chikungunya, and Zika, and the limitations of current vector control strategies, the World ...

CONCLUSIONS: Children are especially vulnerable to this group of diseases due to characteristics that facilitate the development of the most severe forms. More detailed knowledge of this group of diseases allows the pediatrician to diagnose them earlier, implement the correct treatment, monitor warning signs for the most severe forms, and establish effective preventive measures.

Brey, Louis Lambrechts The case-fatality rate of yellow fever virus (YFV) is one of the highest among arthropod-borne viruses (arboviruses). Although historically, the Asia-Pacific region has remained free of YFV, the risk of introduction has never been higher due to the increasing influx of people from endemic regions and the recent outbreaks in Africa and South America. Singapore is a global hub for trade and tourism and therefore at high risk for Y...
