The state of COVID-19 contact tracing following relaxation of the national lockdown: A qualitative study among surveillance response teams in Kampala, Uganda

Introduction: The surge in COVID-19 cases triggered a need for surveillance systems to implement new strategies that augment and accelerate manual contact tracing. In Uganda, COVID-19 cases increased exponentially following the relaxation of the national lockdown. However, little is known about how the surveillance system mitigated COVID-19 transmission during this period. We sought to understand how contact tracing was being conducted in Kampala district following relaxation of the national lockdown. Methods: We conducted a cross-sectional qualitative study, between November and December 2020, among surveillance response officials in the five Divisions of Kampala-Uganda. We purposively selected and interviewed 14 key informants from the Division health offices who included five Division surveillance focal persons, four data analysts and five laboratory personnel. Interviews were audio recorded and transcribed verbatim. We used a conventional approach for content analysis to identify emergent themes. Results: We found that adjustments were made in the contact tracing system to cope with the increasing number of COVID-19 cases. Online and mobile application technology systems including Go-data, WhatsApp, Open Data Kit and City Health Information System were adopted for collection, storage, analysis and reporting of contact tracing data. In one Division, community health workers were trained and engaged. Phone calls were adopted to supplement physical follow-up of contacts. We found managerial barriers such as delays in communication, limited skilled-workforce and insufficient laboratory supplies. Behavioral barriers including lack of cooperation from cases and contacts triggered by perceived stigma affected effective implementation and sustainability of the adjustments in contact tracing. Conclusion: Online systems and engagement of community health workers were adopted to optimize contact tracing coverage in Kampala. There is need to assess the effectiveness and outcomes of digital solutions to contact tracing in resource-limited settings. Besides, clear strategies should be designed to ensure the attainment of gains from community health workers when engaged in surveillance response activities

Ownership and use of long-lasting insecticidal nets three months after a mass distribution campaign in Uganda, 2021

Abstract Background Uganda conducted its third mass long-lasting insecticidal net (LLIN) distribution campaign in 2021. The target of the campaign was to ensure that 100% of households own at least one LLIN per two persons and to achieve 85% use of distributed LLINs. LLIN ownership, use and associated factors were assessed 3 months after the campaign. Methods A cross-sectional household survey was conducted in 14 districts from 13 to 30 April, 2021. Households were selected using multistage sampling. Each was asked about LLIN ownership, use, duration since received to the time of interview, and the presence of LLINs was visually verified. Outcomes were having at least one LLIN per two household members, and individual LLIN use. Modified Poisson regression was used to assess associations between exposures and outcomes. Results In total, 5529 households with 27,585 residents and 15,426 LLINs were included in the analysis. Overall, 95% of households owned ≥ 1 LLIN, 92% of the households owned ≥ 1 LLIN < 3 months old, 64% of households owned ≥ 1 LLIN per two persons in the household. Eighty-seven per cent could sleep under an LLIN if every LLIN in the household were used by two people, but only 69% slept under an LLIN the night before the survey. Factors associated with LLIN ownership included believing that LLINs are protective against malaria (aPR = 1.13; 95% CI  1.04–1.24). Reported use of mosquito repellents was negatively associated with ownership of LLINs (aPR = 0.96; 95% CI 0.95–0.98). The prevalence of LLIN use was 9% higher among persons who had LLINs 3–12 months old (aPR = 1.09; 95% CI  1.06–1.11) and 10% higher among those who had LLINs 13–24 months old (aPR = 1.10; 95% CI  1.06–1.14) than those who had LLINs < 3 months old. Of 3,859 LLINs identified in the households but not used for sleeping the previous night, 3250 (84%) were < 3 months old. Among these 3250, 41% were not used because owners were using old LLINs; 16% were not used because of lack of space for hanging them; 11% were not used because of fear of chemicals in the net; 5% were not used because of dislike of the smell of the nets; and, 27% were not used for other reasons. Conclusion The substantial difference between the population that had access to LLINs and the population that slept under LLINs indicates that the National Malaria Control Programme (NMCP) may need to focus on addressing the main drivers or barriers to LLIN use. NMCP and/or other stakeholders could consider designing and conducting targeted behaviour change communication during subsequent mass distribution of LLINs after the mass distribution campaign to counter misconceptions about new LLINs
