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.

Strengthening laboratory biosafety in Liberia during the COVID-19 pandemic: Experience from the Global Laboratory Leadership Programme

Background The Global Laboratory Leadership Programme (GLLP) has biosafety and biosecurity as one of its core competencies and advocates for a One Health approach involving all relevant sectors across the human-animal-environment interface to empower national laboratory systems and strengthen health security. Decentralization of SARS-CoV-2 testing in Liberia coupled with an increase in the number of COVID-19 infections among laboratory professionals raised biosafety concerns. In response, a set of trainings on laboratory biosafety was launched for lab personnel across the country under the framework of the GLLP. The goal was to deliver a comprehensive package for laboratory biosafety in the context of SARS-CoV-2 through active learning. Methods Three one-day workshops were conducted between September and October 2020, training personnel from human, animal and environmental laboratories through a One Health approach. Concepts critical to laboratory biosafety were delivered in an interactive engagement format to ensure effective learning and retention of concepts. Pre- and post-training assessments were performed, and a paired t-test was used to assess knowledge gain. Results Of the 67 participants, 64 were from the human health sector, one from veterinary sector and two from environmental health sector. The average pre-test score was 41%. The main gaps identified were failure to acknowledge surgical antisepsis as a form of hand hygiene and recognition of PPE as the best risk control measure. The average post-test score was 75.5%. The mean difference of pre-test and post-test scores was statistically significant (p-value <0.001). Participants indicated satisfaction with the workshop content, mode of delivery and trainers' proficiency. Conclusions The workshops were impactful as evidenced by significant improvement (34.5%) in the post-test scores and positive participant feedback. Repeated refresher trainings are vital to addressing the gaps, ensuring compliance, and promoting biosafety culture. GLLP's approach to cultivating multisectoral national laboratory leaders ready to take responsibility and ownership for capacity building provides a sustainable solution for attaining strong national laboratory systems better prepared for health emergencies and pandemics like COVID-19.
