Incidence of Infections Caused by Salmonella Reduced in 2021

THURSDAY, Oct. 6, 2022 (HealthDay News) -- During 2021, there was a decrease in the incidence of infections caused by Salmonella and an increase in incidence of infections caused by Cyclospora, Yersinia, and Vibrio, according to research published in the Oct. 7 issue of the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report.

Jennifer P. Collins, M.D., from the CDC in Atlanta, and colleagues examined progress toward prevention of enteric infections in the United States, summarizing preliminary 2021 data and describing changes in annual incidence compared with to for 2016 to 2018.

The researchers found that during 2021, there was a decrease in the incidence of infections caused by Salmonella, an increase in the incidence of infections caused by Cyclospora, Yersinia, and Vibrio, and no change in the incidence of infections caused by other pathogens. Behavioral modifications and public health interventions implemented to control the COVID-19 pandemic might have reduced enteric infection transmission, as in 2020. Their detection or reporting may have been altered by other factors, including increased use of telemedicine and continued increase in the use of culture-independent diagnostic tests.

"Identifying novel strategies and implementing known strategies to address the root causes of illness are needed to sustainably decrease infections and achieve U.S. Department of Health and Human Services Healthy People 2030 goals," the authors write.
