COVID-19 disproportionately affects the poor and vulnerable. Community health workers are poised to play a pivotal role in fighting the pandemic, especially in countries with less resilient health systems. Drawing from practitioner expertise across four WHO regions, this article outlines the targeted actions needed at different stages of the pandemic to achieve the following goals: (1) PROTECT healthcare workers, (2) INTERRUPT the virus, (3) MAINTAIN existing healthcare services while surging their capacity, and (4) SHIELD the most vulnerable from socioeconomic shocks. While decisive action must be taken now to blunt the impact of the pandemic in countries likely to be hit the hardest, many of the investments in the supply chain, compensation, dedicated supervision, continuous training and performance management necessary for rapid community response in a pandemic are the same as those required to achieve universal healthcare and prevent the next epidemic.

Community health workers (CHWs) are poised to play a pivotal role in fighting the pandemic, especially in low-income countries with vulnerable health systems.
The COVID-19 response must build on existing platforms, infrastructure and relationships wherever possible; the focus should be on supporting the Ministries of Health and regional authorities as they lead coordinated responses.
Immediate investment in community health systems will help achieve the following goals: PROTECT healthcare workers, INTERRUPT the virus, MAINTAIN existing healthcare services while surging their capacity, and SHIELD the most vulnerable from socioeconomic shocks.
Achieving these goals will require targeted actions at different stages of the pandemic. These actions are delineated in the article.
Many of the investments in the supply chain, compensation, dedicated supervision, continuous training and performance management necessary for rapid community response in a pandemic are the same as those required to achieve universal health care and prevent the next epidemic.
Over 823 626 cases of COVID-19 have been reported worldwide as of 1 April 2020, including cases in over 75 low-income and middle-income countries (LMICs).1 COVID-19 disproportionately affects the poor and vulnerable2: sharp increases in COVID-19 case loads will overwhelm health systems in countries already facing shortages of health workers and supplies. With millions of lives at stake, decisive action must be taken now to blunt the impact of the pandemic in countries likely to be hit the hardest.3
Investment is needed at all levels of the health system, and community health workers (CHWs) are poised to play a pivotal role in fighting the pandemic, especially in low-income countries with vulnerable health systems. CHWs that are equipped, trained and supported as part of a well-functioning health system can help keep the pandemic in check.
The Community Health Impact Coalition (CHIC)4 is a network of health practitioners working in over 30 countries that exists to accelerate the uptake of high-impact community health systems design. Its members have developed and supported high-quality community health programmes with governments and communities across the globe, through multiple outbreaks and epidemics.
Given that in a pandemic speed is of the essence, this paper was generated in less than 72 hours using an adapted nominal group technique (NGT). NGT is an organisational planning technique5 that involves four phases: (1) nominal/silent phase: participants individually write their responses to a defined question without discussion; (2) item generation phase: participants take turns sharing their responses, and each response is recorded as a succinct idea without being discussed; (3) discussion/clarification phase: participants ask clarifying questions and delineate the pros/cons of each idea; and (4) voting phase: participants assign ranks to the items. This approach was chosen as it is comprehensive, quick and of low cost.6 It was adapted in the following ways: given that participants were distributed across multiple continents and 12 time zones, phases 1 and 2 took place entirely asynchronously—responses were collected on a shared drive. The discussion phase took place over a 24-hour period, first asynchronously (participants asked and answered questions in a shared word processing document) and subsequently in a video meeting. The final voting phase took place during an additional video meeting. Selection of participants was opportunistic: any health practitioner from the CHIC network was invited to participate.
This paper is intended to advocate for rapid action in response to the evolving COVID-19 pandemic, providing an initial modifiable roadmap to funders, non-governmental organisations and Ministries of Health alike.
The COVID-19 response must build on existing platforms, infrastructure and relationships wherever possible. Maximum leverage and minimum duplication will allow greater short-term success and long-term sustainability.
Our primary focus is supporting the Ministries of Health and regional authorities as they lead coordinated responses. This means integrating all front-line health workers, including CHWs, in the design and implementation of the response.
Immediate investment in community health systems will help achieve the following goals:
PROTECT healthcare workers.
INTERRUPT the virus.
MAINTAIN existing healthcare services while surging their capacity.
SHIELD the most vulnerable from socioeconomic shocks.
PROTECT healthcare workers
Professionalised, proactive CHWs are particularly well placed to build on the foundations of trust they have already established, and to communicate and implement new and rapidly evolving community-level response measures. But to do this, they must be protected.
In Lombardy, Italy, the infection rate is 12 times higher for health workers than for the general population.7 In India, CHWs—the vast majority of whom are women—are conducting contact tracing with neither masks nor hand sanitiser.8 When health workers contract COVID-19, it not only depletes morale, it also depletes our ability to fight the virus.
The need to protect front-line health workers is particularly relevant in places with the worst health workforce shortages: Africa has 3% of the world’s health workforce but nearly a quarter of the world’s burden of disease.9 These shortages are even more pronounced in rural areas, which makes protecting CHWs not only a moral obligation but a strategic one as well.
Global shortages of personal protective equipment (PPE) risk exacerbating existing inequalities, with high-income countries stockpiling supplies and hoarding global manufacturing capacity at the expense of others. CHWs must be included in COVID-19 PPE quantification estimates.
Coordinate with partners and invest to rapidly produce, deploy and restock PPE. The WHO’s COVID-19 Solidarity Response Fund is working to ensure front-line health workers can keep safe and keep serving. Responsive logistics systems already used for sample transport and last mile medicines distribution can track and deliver PPE to the community level, if supplies are adequate and communication systems exist to quickly identify gaps.
Ensure CHWs are included in PPE projections. Not all estimates take CHWs into account; corrective investment will likely be required. Data on CHW numbers, services and distribution exist to inform these plans.
Work with governments to pay CHWs for supplemental hours. This is particularly relevant for part-time or currently unpaid CHWs and those without guaranteed paid sick leave. Where it is deemed feasible, equitable and preferable by CHWs, mobile payments can be used. Given the risk posed by COVID-19 to CHWs and the disruption of their workflows, money currently earmarked for performance-based incentives should be reallocated to cover routine salaries or stipends for all active health workers (box 1).

INTERRUPT the virus
Despite the suggestions of some world leaders, the virus cannot be ‘left to run its course’. This approach would be a death sentence for millions of vulnerable people.10 We must, instead, rapidly scale up testing, bringing it as close as possible to people’s homes. As doctors in Italy have recently noted, an epidemic requires a change from hospital-centred towards community-centred care.11 Supporting CHWs to lead widespread testing, contact tracing, isolation and quarantine will be key to slowing the spread of COVID-19.
Two diagnostic tests currently exist. The current, WHO-approved testing method is polymerase chain reaction (PCR), which detects the genetic code of the novel coronavirus through a nasal swab, oral swab or sputum. It requires advanced laboratory capability that often does not exist in countries with limited preparedness and response resources. An emerging alternative option is the rapid diagnostic test (RDT), which returns results in 15 minutes and can be conducted in the field.12
While RDTs are simpler than PCR, the tests do not deliver or conduct themselves. Healthcare teams must be rapidly expanded, equipped and trained to deliver preventive, diagnostic and management services for COVID-19 (table 2).
Extensive coordination is needed to mobilise private and public sector channels to distribute COVID-19 tests and supplies to highest need areas. Since supply is unlikely to meet demand, these efforts need to be informed by data-driven models that account for capacity, morbidity and mortality risk, and risk of COVID-19 spread in vulnerable areas over time (figure 2).
Standardise and endorse a protocol for CHWs responding to COVID-19.
Engage with governments on the approach for training existing community health teams to prevent, detect and respond. This includes expanding community event-based surveillance modules to incorporate COVID-19 and using mHealth and e-learning tools to accelerate uptake and provide accreditation.13 It is imperative that CHWs demonstrate mastery of infection control skills to keep themselves safe and control the epidemic. Existing digital technologies can support training reinforcement, practice, point-of-care test procedures and clinical guidance, and remote supervision.14
Quantify demand and procure RDTs and other COVID-19 supplies (reagents, swabs). Rapidly deploy these in countries on the brink of their own epidemic. Support governments to fast-track product registration and importation approvals, as well as coordinate distribution.
Continue to invest in ongoing training for community health teams. COVID-19 case definitions, protocols and social distancing policies are expected to change frequently. Consequently, CHW training on COVID-19 needs to be continuous. Consider adaptable, cost-effective ways of sharing information and updates with CHWs (text messages, mobile applications, phone trees, 24-hour support phone number) (box 2).

MAINTAIN existing health services while surging their capacity
During times of crisis, essential health services often decline, which can ultimately kill more people than the pandemic itself.15 One of the greatest dangers of a pandemic is interrupting care for other conditions by overwhelming already under-resourced health systems. For example, during the Ebola epidemic, access to healthcare services fell by half, dramatically increasing deaths from malaria, HIV/AIDS and tuberculosis.16 The vulnerable bore the brunt of the pandemic: childhood immunisations were significantly reduced and, in some areas, the number of pregnant women delivering in health facilities decreased by more than 80%.16
In many countries, health workforce availability remains less than 10% of what is needed to deliver essential primary healthcare services.17 We must continue to provide and expand free, high-quality healthcare for all through investment in stronger health systems—supporting community health teams will be key to ensuring this continuity of care (box 3).18
Roles of community health workers to MAINTAIN and surge existing services25
Sustain routine primary healthcare services, for example, vaccinations and integrated community case management of young children with malaria, pneumonia or diarrhoea.26
Codesign workflow modifications necessary to continue primary healthcare delivery while being responsive to changing pandemic conditions and patient and health worker safety.
Introduce safe means of requesting and accessing care in the event of community-level COVID-19 spread.
Postpone non-essential services to alleviate capacity constraints on existing health workforce.20
Monitor patients for clinical deterioration and support rapid referral of individuals who require hospitalisation, reinforcing links between the health system and communities.
Harness digital technology to receive requests for care, proactively check in with families, follow up with patients, assess symptoms and establish care plans.
Support preparation of health systems and communities for the eventual introduction of still-in-development COVID-19 vaccines and treatments, including outreach to high-risk groups.29
Implement or support disinfection of high-risk surfaces in communities using appropriate infection prevention and control supplies and procedures.
Investments in the national supply chain will be required for new capabilities and surge capacity. Supply chains in many low-income countries are structured for predictable long-term demand, not rapidly changing product requirements. Many countries lack end-to-end visibility into their supply chains, especially at the rural health facility and community levels. Managing routine needs, while layering on additional demand for PPE, test kits and COVID-19 treatment and equipment, will strain even the stronger supply chains in LMICs.19
Moreover, until RDTs are available, testing logistics will require routine, scheduled sample transport networks, such as those already in place in many countries to support community-based HIV programmes. These networks must be equipped for surge capacity to top up inventory of essential supplies or shift inventory between locations, as well as meet the increased need for vehicles, motorbikes, and personnel to transport test samples.
Encourage governments to designate CHWs as essential workers to avoid interruption of essential and life-saving care.
Invest in the national supply chain to quantify demand and coordinate distribution of essential commodities and surge supplies (eg, oxygen, fuel ventilators and outdoor fever tents).
Optimise staffing ratios at all levels of community health system to promote continuity of care. Frequent supportive supervision may be needed, given how rapidly the pandemic and its attendant protocols, procedures and problems will evolve. CHWs facing considerable vulnerability and stress will need more support from supervisors during this period (box 4).

SHIELD the most vulnerable from socioeconomic shocks
COVID-19 will disproportionately affect the poor and vulnerable, worsening prevailing inequalities.20 Strong social support is critical for effective outbreak control.21 Many low-income countries, however, will simply not have the resources to cushion the pandemic’s economic blow. CHWs can help by supporting their communities in several ways (box 5).
Roles of community health workers to SHIELD the vulnerable25
Support self-isolation and monitor patients in the community while ensuring delivery of food, social and medical support.
Combat misinformation, fear and mistrust by acting as a bridge to the formal health system and national authorities. Inspire positive behaviour change and collective action.
Identify and educate at-risk populations (elderly, immunocompromised, those with underlying conditions) to reduce their exposure to COVID-19.
Quarantine is a distinct challenge for many of the communities we serve, where individuals often do not have the resources to effectively self-quarantine. This includes private space for social distancing, the flexibility to stop work and potentially forgo income, and soap, water and hand sanitisers. Vulnerable communities need to be supported by trained, supervised, equipped and protected front-line providers, including CHWs, as part of an effective COVID-19 response.
Support immediate cash injections at the household level and the creation of neighbourhood plans to protect the most vulnerable. Eliminate point-of-care user fees for COVID-19 testing, treatment and care where these exist.
Work with governments and funding partners to ensure that CHW budgets incorporate holistic support, including food supplementation, access to clean water, and mental health and psychosocial support.
Issue a call to multilaterals, regional development banks and national governments to establish economic recovery initiatives to reinvigorate the local economy and support financial recovery for impacted households and businesses.
Invest in surveillance of emerging disease hotspots, which are more concentrated in lower-latitude developing countries. Current emerging infectious disease surveillance and investigation are poorly allocated, with the majority of the globe’s resources focused on places from where the next important emerging pathogen is least likely to originate.22 WHO should consider CHWs as part of the communicable disease surveillance response team (box 6).
SHIELD: tracking impact

An effective response to COVID-19 requires strong coordination across multiple sectors, guided by strong leadership at all levels of the health system. Community-based efforts should be integrated with existing health system infrastructure and aligned with plans and protocols endorsed by the Ministries of Health and regional authorities.
Isolated investments in CHWs for COVID-19 will not work. While strategic investments at all levels of the health system are needed, there are steps we can take now to protect CHWs and communities on the front lines of this pandemic. These steps include mobilising the following:
Appropriate PPE for CHWs and front-line providers.
Rapid test kits for use outside the clinic.
Medicines and equipment for treatment at community and facility levels.
Digital tools for information sharing, communication, training, surveillance and decision support.
COVID-19 reminds us of the urgent need for strong health systems that can provide essential services while protecting against emerging pandemic threats. The investments in the supply chain, compensation, dedicated supervision, continuous training and performance management23 necessary for rapid community response in a pandemic are the same as those required to achieve universal health coverage and prevent the next epidemic. Strengthening high-quality healthcare delivery systems will save lives, not just during COVID-19, but always.
