, an increase in the number of Salmonella Thompson cases was noticed by the Salmonella surveillance in the Netherlands. A casecontrol study was performed, followed by a food investigation. In total 1,149 cases were laboratoryconfirmed between August and December 2012 of which four elderly (76-91 years) were reported to have died due to the infection. The cause of the outbreak was smoked salmon processed at a single site. The smoked salmon had been continuously contaminated in the processing lines through reusable dishes, which turned out to be porous and had become loaded with bacteria. This is the largest outbreak of salmonellosis ever recorded in the Netherlands. The temporary closure of the processing site and recall of the smoked salmon stopped the outbreak. An estimated four to six million Dutch residents were possibly exposed to the contaminated smoked salmon and an estimated 23,000 persons would have had acute gastroenteritis with S. Thompson during this outbreak. This outbreak showed that close collaboration between diagnostic laboratories, regional public health services, the national institute for public health and the food safety authorities is essential in outbreak investigations.

COVID-19 has disproportionately affected vulnerable populations across the U.S. Street-based sex workers are one vulnerable population whose health and impact of COVID-19 have been understudied to date. The goal of this study was to evaluate findings from a community needs assessment with street-based sex workers on impact of COVID-19 on health behaviors and social circumstances. A brief survey was developed at a community-based harm reduction and recovery services organization. Surveys were administered by peer specialists to street-based sex workers during street outreach in April and May 2020. A total of 46 surveys were analyzed. Many individuals reported continuing to do sex work and use substances during the COVID pandemic. Slightly more than a quarter of individuals ( n = 13; 28.3%) indicated using personal protective equipment while doing sex work and described challenges to using precautions when working with clients. Individuals had used marijuana ( n = 32, 71.1%), cocaine ( n = 17, 39.5%), prescription stimulants ( n = 9, 21.4%), methamphetamines ( n = 5, 11.9%), prescription opioids ( n = 12, 27.3%), street opioids ( n = 12, 27.3%), sedatives ( n = 11, 25.0%), hallucinogens ( n = 3, 6.8%), inhalants ( n = 3, 7.0%), or some other substance ( n = 4, 8.7%) in the past 30 days. About half (48.8%) reported that COVID-19 had a major impact on their lives. This study is among the first to characterize the impact of COVID-19 on street-based sex workers. From a public health standpoint, this group also represents a high-priority population given their vulnerability and close contact with others, which increases the potential for community spread.

COVID-19 is a public health crisis that has fundamentally altered health care provision. The purpose of this study was to examine the impact of COVID-19 on pre-exposure prophylaxis (PrEP) care. We reviewed all patient records for those who presented for PrEP care at a PrEP program in Providence, Rhode Island from September 1st, 2019 to May 29th, 2020. The number of PrEP encounters decreased but was not significantly different over time (ps > .05). Patients were still able to access PrEP clinical services during the COVID-19 pandemic. Implementing flexible and timely PrEP delivery approaches in this setting likely minimized the disruption of PrEP care during COVID-19. Keywords Pre-exposure prophylaxis (PrEP) • HIV prevention • Clinical care • COVID-19Resumen COVID-19 es una crisis de salud pública que ha alterado fundamentalmente la prestación de servicios de salud. El propósito de este estudio fue examinar el impacto de COVID-19 en los servicios de la profilaxis preexposición (PrEP). Revisamos todos los registros de pacientes que se presentaron para recibir atención de PrEP en un programa de PrEP en Providence, Rhode Island desde el 1 de septiembre de 2019 hasta el 29 de mayo de 2020. El número de encuentros de PrEP disminuyó pero no fue significativamente diferente con el paso del tiempo (ps > .05). Los pacientes aún pudieron acceder a los servicios clínicos de PrEP durante la pandemia de COVID-19. La implementación de enfoques de entrega de PrEP que eran flexibles y oportunos en este entorno probablemente minimizó la interrupción de la atención médica de la PrEP durante COVID-19.
