Incorporating COVID-19 into Acute Febrile Illness Surveillance Systems, Belize, Kenya, Ethiopia, Peru, and Liberia, 2020-2021.

Existing acute febrile illness (AFI) surveillance systems can be leveraged to identify and characterize emerging pathogens, such as SARS-CoV-2, which causes COVID-19. The US Centers for Disease Control and Prevention collaborated with ministries of health and implementing partners in Belize, Ethiopia, Kenya, Liberia, and Peru to adapt AFI surveillance systems to generate COVID-19 response information. Staff at sentinel sites collected epidemiologic data from persons meeting AFI criteria and specimens for SARS-CoV-2 testing. A total of 5,501 patients with AFI were enrolled during March 2020-October 2021; >69% underwent SARS-CoV-2 testing. Percentage positivity for SARS-CoV-2 ranged from 4% (87/2,151, Kenya) to 19% (22/115, Ethiopia). We show SARS-CoV-2 testing was successfully integrated into AFI surveillance in 5 low- to middle-income countries to detect COVID-19 within AFI care-seeking populations. AFI surveillance systems can be used to build capacity to detect and respond to both emerging and endemic infectious disease threats.

Use of rapid behavioral assessments to determine the prevalence of HIV risk behaviors in high-risk populations.

Rapid HIV Behavioral Assessment (RHBA) is a method for collecting much-needed information about sexual, drug-use, and HIV testing behaviors from people at high risk for HIV infection in areas with low-to-moderate HIV prevalence. During 2004, RHBAs were conducted in seven small to moderate-sized cities in the United States during Gay Pride events. Anonymous 10-minute interviews were administered to eligible attendees using handheld computers. Depending on the city, between 47% and 97% of individuals approached agreed to hear more about the survey. Enrollment rates exceeded 90% in every location. RHBAs conducted during 2004 were well received by the gay and public health communities. They were simple to organize and administer, flexible, and cost-efficient, suggesting that this approach holds promise for expansion to additional high-risk groups and geographic locations. RHBAs can provide state and local health departments with demographic and behavioral data that can be used to design, target, and evaluate local HIV prevention programs.
