World Health Day and National Public Health Week: Why Infection Prevention, EVS, and SPD Are Central to Safer Health Systems

Each year, World Health Day and National Public Health Week serve as reminders that health is not confined to hospitals, clinics, or even national borders. It is a shared responsibility that depends on coordinated systems, trusted professionals, and evidence-based action.

This year, World Health Day falls on April 7, 2026, and National Public Health Week runs from April 6 to 12.

For infection preventionists (IPs), environmental services (EVS) professionals, and sterile processing (SP) technicians, these observances are not merely symbolic. They are a moment to recognize the often-unseen work that keeps patients safe and health systems functioning.

Infection prevention and control (IPC) does not exist in isolation. It is a team-based discipline. While IPs guide strategy and surveillance, EVS and SP teams operationalize safety at the point of care. Together, they form the foundation of effective infection prevention.

“World Health Day and National Public Health Week remind us that public health is not an abstract concept, but built, protected, and sustained by the people who safeguard our environments, our instruments, and our patients every single day,” said Vangie Dennis, MSN, RN, CNOR, CMLSO, FAORN, FAAN, perioperative consultant for Perioperative Consulting, LLC, and a member of the Infection Control Today^®’s (ICT^®’s) Editorial Advisory Board (EAB). “Infection prevention, EVS, and SP are not support functions; they are the backbone of safe, resilient, and high‑reliability health systems. When these disciplines are strong, aligned, and empowered, patient harm decreases, outbreaks are prevented, and the entire continuum of care becomes safer.”

Bridging Health Care and Public Health

The COVID-19 pandemic reinforced what these teams have always known: Health care environments are deeply connected to the communities they serve. Pathogens move between settings and artificial borders, and prevention must move with them.

World Health Day emphasizes global health resilience, while National Public Health Week focuses on community action. IPs translate guidance into practice, but they rely on EVS teams to maintain clean, safe environments and on SP professionals to ensure that every instrument used in patient care is safe and functional.

Surveillance data may identify risks, but it is EVS and SP departments that close the loop. A disinfected surface or a properly reprocessed instrument represents the final, critical step in preventing transmission.

“On World Health Day and National Public Health Week, we are reminded that safer health systems are not defined by policy alone, but by disciplined practice at every point of care.” Shazia Irum, MSc, MBA, RN, CIC, CPHQ, FAPIC, is the CBIC Ambassador from Riyadh, Saudi Arabia, and another member of ICT’s EAB. “Infection prevention, EVS, and SP form the critical infrastructure of patient safety, where precision, consistency, and accountability directly translate into lives protected. Excellence in these domains is not optional; it is a professional obligation. When we uphold the highest standards, even in unseen moments, we reinforce a culture of safety and trust. Strong systems are built by those who choose vigilance over complacency and leadership over routine.”

The Expanding Scope of Infection Prevention

The role of IPC has expanded significantly in recent years. It now includes antimicrobial stewardship, outbreak preparedness, and addressing misinformation. However, these efforts depend heavily on frontline execution.

EVS professionals are responsible for one of the most fundamental aspects of infection prevention: cleaning and disinfection. Their work directly impacts pathogen transmission, yet it is often undervalued or misunderstood.

Similarly, SP technicians play a critical role in perioperative and procedural safety. Every surgical instrument, every device used in patient care, must be cleaned, inspected, and sterilized correctly. When this process is done well, it is invisible. When it fails, the consequences can be severe and, sometimes, deadly.

Public health observances such as these 2 provide an opportunity to highlight that these roles are not ancillary but essential.

Health Equity and the Frontline Workforce

Health equity is a central theme of both observances, and it applies not only to patients but also to the workforce.

EVS and SP professionals often face staffing shortages, limited resources, and insufficient recognition. Yet they are expected to meet increasing standards and adapt to evolving risks.

IPs must advocate for these teams, ensuring they have the training, staffing, and support needed to perform their roles effectively. Safe patient care cannot be achieved without safe, well-supported staff.

“As we mark World Health Day and National Public Health Week, leaders must recognize that infection prevention, EVS, and SP are not operational afterthoughts—they are strategic levers for national resilience,” said Hebah Ibrahim Al-Zamel, MSN, CIC, CPHQ, LTC-CIP, the infection control coordinator for the Quality Department for the King Abdullah University Hospital in Irbid, Jordan, and a member of ICT’s EAB.

She continues, “When policy elevates these disciplines, we strengthen our capacity to prevent outbreaks, safeguard health care workers, and ensure that every patient receives care in a safe environment. Investing in these functions is an investment in the stability and credibility of the entire health system.”

Communication and Collaboration

Effective infection prevention depends on communication across disciplines. IPs, EVS teams, and SPD technicians must work in alignment, not in silos.

Education is a shared responsibility. EVS staff must understand the “why” behind cleaning protocols. SPD technicians must be included in discussions about device selection and workflow changes. Infection preventionists must listen as well as lead.

Trust is built when all voices are valued. When EVS or SPD teams identify challenges, those insights should inform policy and process improvements.

“We often talk about public health as if it happens in a vacuum or outside the hospital—in communities, in policy rooms, in public campaigns. But safer health systems are built from the inside out,” Peter Graves, BSN, RN, CNOR, the CEO and independent consultant for Clinical Solution, LLC, and a member of ICT’s EAB. “They start at the bedside, with the perioperative nurse who preps the skin before the incision, the SPD technician who ensures every instrument is sterile before it enters a body, and the EVS professional who meticulously cleans a room between cases so the next patient never inherits the last one's risk. These aren't supporting roles sitting at the edges of care; they are at the front line of infection prevention. They are public health in scrubs, in action, every single shift. And sadly, they are all too often among the most chronically underfunded, underrecognized, and underrepresented voices in the conversations that shape patient safety policy.”

Graves emphasizes, “World Health Day and National Public Health Week give us a moment to correct that. Safer health systems don't happen by accident—they happen because these professionals show up every day and do the work that most people never see.”

Prevention Happens in the Details

Public health campaigns often focus on large-scale initiatives, but infection prevention is built on small, consistent actions.

• A properly disinfected high-touch surface.
• A correctly assembled instrument tray.
• A validated sterilization cycle.

These actions may seem routine, but they are the frontline defense against infection.

EVS professionals ensure that pathogens do not persist in the environment. SP technicians ensure that instruments do not pose a risk to the patient. IPs ensure that these processes are evidence-based and consistently applied.

“Surface disinfection is one of the most controllable variables in infection prevention, and EVS determines how consistently it’s done and verified,” Donald Sipp, MBA, RESE, CHESP, CHTI-2, CMIP, PMP, senior director of Rock Schockey Associates, Inc, owner of Impact Training Company, and a member of ICT’s EAB.

Each role is essential. None can function effectively without the others.

Leadership Without a Title

Leadership in IPC is not limited to formal roles. It is demonstrated every day by individuals who take ownership of patient safety.

• Environmental services professionals who go beyond checklist cleaning.
• SP technicians who question unclear instructions for use (IPUs).
• IPs who advocate for resources and system improvements.

This is leadership in action.

These professionals may not always be visible in executive meetings, but their impact is felt in every safe patient encounter.

“Infection prevention, EVS, and SPD are the quiet backbone of patient safety,” Maureen Spencer, MEd, BSN, RN, CIC, FAPIC, the CEO of Surgical Infection Consultants, and a member of ICT’s EAB. “They’re the teams working behind the scenes, long before a patient ever enters a room or an instrument touches the field. Patients may never meet them, but every clean environment, every properly sterilized tray, and every infection that never happens is a direct result of their work.”

Looking Forward

As health care continues to evolve, the need for integrated infection prevention teams will only grow. Emerging threats such as antimicrobial resistance, environmental contamination, and complex medical devices require coordinated responses.

World Health Day and National Public Health Week provide an opportunity to reflect on these challenges while recognizing the progress that has been made.

However, progress is not sustainable without investment in people. Infection prevention programs must include and elevate EVS and SP as core components, not afterthoughts.

A Moment to Reaffirm the Mission

For IPs, EVS professionals, and SP technicians, these observances serve as a reminder of our shared purpose.

Every clean surface, every sterile instrument, and every prevented infection represents a success that may never be seen but is always felt.

Together, these teams protect patients, support colleagues, and strengthen health systems.

“I am a firm believer that EVS, SPD staff, and IPs are the backbone of any health care system,” Shahbaz Salehi, MD, MPH, MSHIA, director of infection prevention and control and employee health for Foothill Regional Medical Center in Tustin, California, and another member of ICT’s EAB. “Without them, we wouldn’t have clean facilities, sterile instruments, or the champions driving reductions in health care-associated infections.”
