Objective: To assess the impact of the COVID-19 pandemic on the state-level enteric disease workforce and routine enteric disease surveillance and outbreak investigation activities in the western United States.
Design And Setting: Key informant interviews conducted using bidirectional video from March to April 2022.
Participants: Enteric disease epidemiologists at state public health agencies in the western states served by the Colorado and Washington Integrated Food Safety Centers of Excellence.
Article Synopsis
- New Aedes-borne viruses have emerged in the US and Europe, necessitating better control strategies for Aedes albopictus, a significant mosquito nuisance and virus carrier, as current vector control methods are lacking.
- A study tested a novel metofluthrin emanator, revealing it significantly reduced mosquito landings by up to 89.5% outdoors and 74.6% indoors when placed nearby humans.
- The emanator showed effective protection for about 2.5 weeks outdoors before losing efficacy, indicating it could be a viable option for controlling Aedes albopictus bites in various settings.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic necessitated rapid local public health response, but studies examining the impact of social distancing policies on SARS-CoV-2 transmission have struggled to capture regional-level dynamics. We developed a susceptible-exposed-infected-recovered transmission model, parameterized to Colorado, USA‒specific data, to estimate the impact of coronavirus disease‒related policy measures on mobility and SARS-CoV-2 transmission in real time. During March‒June 2020, we estimated unknown parameter values and generated scenario-based projections of future clinical care needs.
