This article examines the experience of healthcare professionals working in primary healthcare provision during the first wave of the COVID-19 pandemic in North Kivu, the Democratic Republic of the Congo, and in Kambia District, Sierra Leone. Drawing on ethnographic observation, interviews and focus groups, we explore everyday narratives of 'crisis' in these two regions which had recently seen Ebola epidemics. In describing the impact of COVID-19 on their life, work, and relationships with patients, healthcare workers made sense of the pandemic in relation to broader experiences of structural economic and political crisis, as well as differing experiences of recent Ebola epidemics. There were contradictory experiences of rupture and continuity: whilst COVID-19 disrupted routine health provision and exacerbated tensions with patients, the pandemic was also described as continuity, interacting with broader structural problems and longer-term experiences of 'crisis'. In effect, healthcare workers experienced the COVID-19 pandemic at the crossroads between the exceptional and the everyday, where states of exception brought by emergency measures shed new light on long-standing tensions and structural crisis.

The COVID-19 pandemic challenged countries to protect their populations from this emerging disease. One aspect of that challenge was to rapidly modify national surveillance systems or create new systems that would effectively detect new cases of COVID-19. Fifty-five countries leveraged past investments in District Health Information Software version 2 (DHIS2) to quickly adapt their national public health surveillance systems for COVID-19 case reporting and response activities. We provide background on DHIS2 and describe case studies from Sierra Leone, Sri Lanka, and Uganda to illustrate how the DHIS2 platform, its community of practice, long-term capacity building, and local autonomy enabled countries to establish an effective COVID-19 response. With these case studies, we provide valuable insights and recommendations for strategies that can be used for national electronic disease surveillance platforms to detect new and emerging pathogens and respond to public health emergencies.

We explored the association of Ebola virus antibody seropositivity and concentration with potential risk factors for infection. Among 1,282 adults and children from a community affected by the 2014-2016 Ebola outbreak in Sierra Leone, 8% were seropositive for virus antibodies but never experienced disease symptoms. Antibody concentration increased with age.
