Yellow Fever Response in Isiolo Exposed a Deep Trust Problem

In January 2022, yellow fever cases were identified in Isiolo County for the first time, and Kenya moved quickly into a national vaccination response. By July, 181,000 people had been vaccinated, covering about 72% of the eligible population. On paper, the campaign looked like a public health success. On the ground, it revealed how outbreak control can be complicated by distrust, administrative distance, and long memories of punitive state action.

The article examines how those tensions played out through Community Health Volunteers, or CHVs, who sat at the center of the response while remaining socially and institutionally exposed. Rather than treating vaccination as a simple technical intervention, the authors frame the campaign as a social encounter shaped by Kenya’s northeast history of uneven governance. In this setting, disease control did not arrive as neutral care. It arrived as authority.

Vaccination Campaigns Can Carry the Weight of State Power

The response in Isiolo unfolded in a region where government action has often oscillated between neglect and heavy-handed intervention. That history mattered because residents did not necessarily experience the campaign as a discrete emergency measure aimed at preventing yellow fever transmission. For some communities, the vaccination effort appeared alongside older patterns of surveillance, control, and extraction. The state’s visible presence during a health crisis can therefore trigger suspicion rather than reassurance, especially where public services have long been thin or unevenly distributed.

CHVs were the face of this campaign. They were expected to persuade households, explain the value of vaccination, and mediate between local residents and national authorities. Yet they also embodied the very structures that many community members distrusted. Their role was unstable from the start: they were community representatives, but they were also seen as extensions of the state. In outbreak settings, that dual identity can be indispensable. It can also make volunteers the first target of anger when suspicion hardens.

Fanon’s Lens Clarifies the Emotional Burden on Volunteers

To interpret this conflict, the article uses a Fanonian lens and draws on Fanon’s idea of the psychoexistential complex. In practical terms, the concept helps explain what happens when people are caught between social worlds that do not fully accept them. CHVs were positioned between their neighbors and the institutions directing the response, and that in-between status produced strain. They had to promote a campaign they did not control while absorbing the frustrations of people who associated health interventions with external power.

That burden was intensified by precarity and invisibility. CHVs often work without secure recognition, durable support, or visible institutional status, even when they are expected to carry out essential outreach. Their labor becomes most visible during emergencies, when officials need rapid coverage and community access. Outside those moments, their presence can recede from policy attention. The result is a role that is socially demanding but structurally fragile.

The emotional consequence is not abstract. When a volunteer must defend a campaign in a place where state encounters have often been adversarial, every conversation can become a test of legitimacy. A refusal from one household is never just a refusal of a vaccine. It can also be a rejection of the messenger, the institution behind the messenger, and the broader political order the messenger is perceived to represent.

Coloniality Helped Shape the Campaign’s Social Friction

The article’s central argument is that coloniality persisted within the yellow fever response. Here, coloniality refers to durable patterns of domination that continue to shape who is heard, who is trusted, and who carries the burden of intervention. The campaign may have been medically justified, but its implementation was still filtered through local histories of unequal power. Top-down coordination from nationally controlled actors amplified that tension. Rather than building confidence through shared ownership, the process could deepen the sense that decisions were being imposed from above.

This matters because outbreak response depends on more than vaccine supply, logistics, and coverage targets. It also depends on whether communities see the intervention as protective and whether frontline workers feel supported enough to sustain engagement. In Isiolo, the social cost of implementation was borne disproportionately by CHVs, who had to translate a centrally driven campaign into local terms while contending with skepticism about the authorities behind it.

The article does not treat resistance as irrational. It treats it as historically informed. In settings marked by uneven development and prior coercive contact, public health action can be interpreted through the same lens as other state encounters. That interpretation changes how campaigns unfold at the bedside, at the household gate, and in the informal spaces where health advice is debated.

CHVs Were Asked to Bridge a Gap They Did Not Create

The fieldwork, conducted over 12 months from 2022 to 2023, combined ethnography with in-depth interviews and focus group discussions. This design allowed the authors to center CHV experiences across the ten-day campaign rather than relying only on coverage metrics or administrative outcomes. The resulting picture is less about whether vaccination occurred and more about what it cost socially to make it happen.

One of the strongest implications is that CHVs should not be treated as expendable intermediaries. They need protection, capacity, and public recognition if they are to function effectively during future outbreaks. Their visibility should not depend solely on moments of crisis. When volunteers are left to absorb distrust without institutional backing, the health system effectively shifts the emotional and political burden of implementation onto the least protected actors in the chain.

Their position was especially difficult because they were expected to represent a campaign whose authority was contested from the outset. In that sense, the response in Isiolo was not only a vaccination exercise. It was also a test of how much legitimacy a health system can borrow from community workers without giving them the material and symbolic support they need.

A Public Health Campaign Cannot Succeed on Logistics Alone

Yellow fever control in Kenya’s northeast shows how quickly an outbreak response can become a referendum on governance. The vaccination numbers were substantial, but they do not capture the full social terrain of the campaign. The article places CHVs at the center of that terrain and shows how their labor was shaped by long-standing histories of neglect, coercion, and institutional invisibility.

For future outbreak planning, the lesson is concrete. Community health work cannot be treated as a disposable add-on to centralized emergency response. It requires stable support, protection from backlash, and genuine incorporation into decision-making structures. Without those conditions, the next campaign may again achieve coverage while leaving frontline volunteers exposed to the same tensions that shaped the yellow fever response in Isiolo.
