Participate in the PacVec needs assessment!
Our center is conducting a needs assessment to understand perceived gaps in training and workforce needs relating to vector-borne disease and public health. Information gained from the needs assessment will be used to develop a PacVec short-course training curriculum to meet the needs of vector control and public health agencies and to expand the potential recruitment pool for the vector control workforce. Learn more about PacVec here. Please circulate this needs assessment among your networks within the Pacific Southwest. Participate in the needs assessment by Friday, September 18th, 2020!

Systematic review: Impact of socioeconomic factors on Aedes aegypti mosquito distribution in the mainland United States

Across most of its distribution, Aedes aegypti relies on human blood meals and peridomestic habitats for reproduction. Due to the close relationship between Ae. aegypti and humans, socioeconomic factors may affect the spread of Ae. aegypti. PacVec trainee Whitney Holeva-Eklund led a systematic review of the published literature on the associations between socioeconomic variables and the distribution of Ae. aegypti mosquitoes in the mainland US. The paper points to inconsistent relationships between the studied socioeconomic factors and the distribution and abundance of Ae. aegypti [full article].

Update on arbovirus activity in the Pacific Southwest
More mosquitoes from counties across the Pacific Southwest have tested positive for West Nile virus (WNV) and St. Louis encephalitis virus (SLEV). WNV disease reported:
Vector control and public health agencies continue to urge the public to take precautions such as applying repellents on exposed skin and getting rid of mosquito breeding sites.

Dengue continues in the US-affiliated Pacific Islands
Republic of Marshall Islands: There have been 3,561 cases (20 more cases since 19 August) of dengue-like illness (DLI), of which 1,704 have been laboratory-confirmed between May 2019 and 24 August 2020. Two deaths were reported since June 2019. The outbreak is reported to be ongoing.

Yap State, Federated States of Micronesia (FSM): A total of 39 DLI cases were seen during epi weeks 32-34 bringing the total number of DLI cases to 1,785 since 1 January 2019

Aedes Challenge 2020: Model forecasts invited
UPDATE: Because of the many challenges caused by COVID-19, we have decided to accept forecasts for the Aedes Challenge throughout the remainder of 2020. Interested modeling groups may register at anytime, and forecasts must be submitted before the first day of the month(s) being predicted. See the original announcement below, along with the link to the Aedes Challenge website.
The Centers for Disease Control and Prevention (CDC) Division of Vector-Borne Diseases and the CDC Epidemic Prediction Initiative, in collaboration with the Council of State and Territorial Epidemiologists and the Centers of Excellence in Vector-Borne Diseases, are pleased to announce an open Aedes forecasting challenge for 2020. The Aedes Forecasting Challenge focuses on predicting the seasonal presence of Ae. aegypti and Ae. albopictus in a subset of U.S. counties from multiple states across the country. The challenge is open to anyone and any methodological approach. Further details on how to submit forecasts can be found on CDC's Epidemic Prediction Initiative website. Please disseminate this announcement widely to any modelers who may be interested. Any questions can be directed to aedeschallenge@cdc.gov.
PacVec Resistance Testing
The Kearney Center has transitioned to remote work as a precaution due to the COVID-19 outbreak. This means any requested insecticide resistance testing or workshops will need to wait until normal activities resume. Dr. Anton Cornel and Katherine Brisco will still be available to offer resistance testing support and guidance at this time through email (bioassays@pacvec.us) or teleconferencing.
Videos on Larval Mosquito Resistance Testing
 
In collaboration with partners at the Mosquito and Vector Control Association of California, PacVec CoE has produced new training videos providing an overview of resistance testing for larval mosquitoes. The videos discuss the rationale for monitoring resistance in mosquitoes, an overview of dose responses and how the dose response changes as resistance to larvicides evolves in a mosquito population, the different types of larval mosquito control agents, the supplies needed for carrying out bioassays, bioassay set-up and making stock solutions of control agents, and interpreting the bioassay results. See the videos and related materials at https://pacvec.us/resources/
Need Bottle Bioassay Testing?
 
If you have mosquito (Aedes or Culex) samples to be tested for insecticide resistance, PacVec is providing testing and training services at no charge, and all results will be returned to you. Dr. Anton Cornel's laboratory is leading this activity and organizing various regional training workshops on bottle bioassay testing. If you are interested, please contact us right away at bioassays@pacvec.us to arrange for shipment and timing of the testing.

Vector Control and Public Health Agencies Need Summer Interns for 2020, or Just Help Advertising Positions for Students?
Please contact us anytime if your agency has seasonal positions that may be of interest to undergraduate students in the Pacific Southwest region. Such positions are important formative experiences for students, and they are excellent opportunities to raise awareness of career opportunities in vector-borne diseases. These can be simple job postings that we will advertise to our undergraduates or we can help you partner with faculty for project-based internships that involve academic credit with a faculty mentor and possible continued data analysis during the school year. If you are interested, please send us a note at training@pacvec.us. To maximize your audience and reach the best candidates for your positions, please send us these position announcements as early as possible, ideally in January or February, before students have settled their summer plans.
