Implementation and contribution of temperature screening and handwashing practice at points of entry for COVID-19 pandemic response in a humanitarian crisis setting.

Introduction: over the last decade, insecurity in the Lake Chad Basin has triggered an unprecedented humanitarian crisis in the Niger´s Diffa Region with a significant population movement. In this humanitarian setting, we reviewed the implementation process and the contribution of temperature screening and handwashing practice at points of entry as part of non-pharmaceutical interventions against COVID-19.

Methods: in Diffa, border officers were trained on the fundamentals of infection prevention and control in relation to COVID-19 readiness and response and a 14-day district response team was constituted. To examine the significance of the implementation process of temperature screening and handwashing practices at points of entry, we conducted a secondary analysis of data submitted by the six health districts of the Diffa Region between March and July 2020.

Results: travellers screened for fever ranged from 10,499 (in March 2020) to 62,441 (in April 2020) with the health districts of Diffa (mean: standard error of the mean: 25,999: 9,220) and of Bosso (mean: standard error of the mean: 30.4: 19.1) accounting for the most and the least of activities during the entire period, respectively. Overall, 125/169,475 travellers presented fever and were effectively quarantined. Only the Ngourti Health District reported travellers who declined handwashing (54/169,475); this was during the first three months of the first wave of the COVID-19 pandemic.

Conclusion: we have documented a successful implementation of measures related to temperature screening with some unsubstantial denial of handwashing. Given the importance of border traffic due to insecurity in the Diffa Region, maintaining temperature screening and handwashing in this humanitarian setting is necessary but requires coordinated actions of all stakeholders involved in the region.
