The Ebola response showed the importance of investments that build health system resilience, notably investments in the health workforce.11Kruk ME Myers M Tornorlah Varpilah S Dahn BT What is a resilient health system?

At the onset of the COVID-19 pandemic in sub-Saharan Africa, governments took swift action to institute lockdown measures, activate incident management response systems, and mobilise front-line health workers to be trained. However, some months into the pandemic preliminary evidence suggests that human resources for health in sub-Saharan Africa have been inadequately prepared. Community health workers (CHWs) have insufficient personal protective equipment (PPE) to ensure they can continue providing essential care14Ballard M Westgate C COVID19: it ain't over until there's PPE all over.Think Global Health.

In Rivercess County, Liberia, where there has only been one suspected COVID-19 case that was confirmed negative as of June 30, 2020, some caregivers refuse to attend mobile clinics or facilities for vaccinations and there has been a reduction in care seeking among some adults (Saykpah R, unpublished). People fear health workers are spreading COVID-19 and CHWs, while trusted neighbours, have insufficient PPE to convince people otherwise. The stakes are high for people's health if there is any reduction in care-seeking behaviour for preventable diseases.19Walker D Chi Y-L Glassman A Chalkidou K More harm than good?

CHWs matter because they are trusted members of the community who are often the most accessible point of care, particularly for vulnerable populations—eg, in Sierra Leone, CHWs outnumber doctors 95 to one.21World BankPhysicians per 1,000 and community health workers per 1,000.https://data.worldbank.org/indicator/SH.MED.PHYS.ZSDate: 2020Date accessed: June 25, 2020Google Scholar Indeed, the Africa Centres for Disease Control and Prevention is planning to recruit 1 million community health volunteers to support contact tracing across sub-Saharan Africa,22Africa CDC African Union rolls out partnership to accelerate COVID-19 testing.https://africacdc.org/news-item/african-union-rolls-out-partnership-to-accelerate-covid-19-testing/Date: June 4, 2020Date accessed: June 25, 2020Google Scholar relying on existing CHW cadres. Ongoing efforts to leverage CHWs for the COVID-19 response must not be one-offs in the face of an emergency.
