‘People Were Really Quite Stunned’: Dr. Caroline Ryan, Incoming CDC Country Director for Ethiopia, Shares Lessons from the Fight Against HIV, COVID-19 in Eswatini

When Dr. Caroline Ryan became the CDC Country Director for Eswatini in 2015, the small kingdom in Southern Africa (then known as Swaziland) had the highest rate of HIV in the world – 27% of the adult population. But there was reason to be optimistic.

The following year, a study showed that the number of new infections in the country had been nearly halved and the number of people who were on antiretrovirals that were virally suppressed had doubled.

COVID-19 In-Depth Report: Summary of Evidence Related to the Risk of Other Infections in the Context of COVID-19

Severe COVID-19 is associated with critical illness and immune dysregulation, both of which have been previously associated with increased risk of nosocomial infection. The care of COVID-19 patients has required dramatic changes to usual hospital practices and heightened concern for infection control practices. This is a brief summary of published evidence related to the effect of the COVID-19 pandemic on non-COVID infections.

Double Dose of Debate: Opinions Vary on Timing of COVID Vaccine Shots as Potential 4th Wave Looms (includes Ruanne Barnabas)

by Lisa Stiffler  / March 19, 2021

With COVID-19 vaccines still in limited supply and case counts threatening to resurge, there is a debate over the benefits of giving more people their first shot and waiting a longer time to administer the second dose, or whether to stay the course and prioritize getting both doses of the Pfizer and Moderna vaccine into arms as quickly as possible.

New COVID-19 In-Depth Report: Summary of SARS-CoV-2 Novel Variants

At just over one year into the COVID-19 pandemic, evolution of SARS-CoV-2 has generated viral variants that differ in their genetic sequence from the strain first detected in December 2019. Evidence is emerging about how these variants differ in their transmission characteristics, associated clinical symptoms, and vaccine efficacy. This document is a brief summary of published evidence about characteristics of SARS-CoV-2 variants that may impact the public health response, including transmission and response to vaccination.

Summary of Evidence Related to Indoor Ventilation to Reduce SARS-CoV-2 Transmission

This updated in-depth summary (previously released on December 21, 2020) is issued in response to new information that we received about updated definitions of aerosol particles that show that larger respiratory particles (<100 μm) can remain airborne for extended periods, and that in enclosed areas with poor ventilation, these aerosols containing infectious SARS-CoV-2 can spread beyond 6 feet and build up in a room. We apologize for not including this information in the earlier version of this summary.

How Widespread is Mask-Wearing in Washington? UW Study Aims to Find Out, Starting in King County (includes Judith Wasserheit and Brandon Guthrie)
