Navigating Infectious Disease Exposures for Pregnant Workers a Guide for HR Teams

Why pregnant workers face heightened risk during infectious disease outbreaks

Pregnancy brings meaningful physiological changes that can affect how the body responds to infections. Immune function shifts during pregnancy to protect the developing fetus, and these shifts can leave pregnant workers more vulnerable to certain pathogens or more likely to experience severe complications if infected. Respiratory viruses, influenza, and some bacterial infections carry documented risks for pregnant individuals that differ from the general workforce. HR teams that understand this biological reality are better positioned to build policies that actually protect people rather than simply checking a compliance box.

The exposure risks are rarely hypothetical. Healthcare workers, educators, food service employees, and anyone working in close contact with large numbers of people face regular infectious disease exposure as part of the job. When a pregnant worker holds one of these roles, the question is not whether exposure might happen but what the organization will do when it does. A clear, pre-established framework for responding to infectious disease exposures involving pregnant workers reduces decision-making under pressure and signals to employees that their safety is taken seriously.

Legal obligations HR must understand

Several overlapping legal frameworks govern how employers must respond when a pregnant worker is exposed to an infectious disease at work. The Pregnancy Discrimination Act prohibits treating pregnant workers less favorably than similarly situated non-pregnant workers, but it also requires that pregnant workers be accommodated to the same extent that the employer accommodates other workers with temporary conditions affecting their ability to work. If an employer routinely offers light-duty assignments or temporary reassignments to workers recovering from injuries, it must offer comparable options to pregnant workers who cannot safely perform certain tasks due to infection risk.

The Pregnant Workers Fairness Act, which took effect in 2023, strengthened these obligations considerably. Under the PWFA, employers with 15 or more employees must provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions, unless doing so would impose an undue hardship. Infectious disease exposure risk during pregnancy qualifies as a limitation that may require accommodation. Refusing to engage in the interactive process when a pregnant worker raises concerns about infection risk exposes the employer to significant legal liability. Understanding how employment law protects workers during medical situations is foundational for every HR professional managing a workforce that includes pregnant employees.

OSHA's General Duty Clause requires employers to provide a workplace free from recognized hazards likely to cause death or serious physical harm. When an infectious disease outbreak occurs in a workplace, and when pregnant workers have documented increased risk, that standard applies. OSHA has issued guidance on specific pathogens, including Zika and COVID-19, explicitly acknowledging elevated risk for pregnant workers. HR teams should monitor OSHA and CDC guidance updates and incorporate them into their infectious disease response protocols.

Building a practical infectious disease accommodation protocol

Effective protocols start before any exposure occurs. HR should work with occupational health professionals and legal counsel to develop a written policy that addresses infectious disease exposure events and the specific considerations that apply to pregnant workers. This policy should define what constitutes a significant exposure, outline the notification process, explain the range of available accommodations, and clarify how decisions will be made and documented.

When a pregnant worker reports an exposure or raises concerns about infection risk, the interactive process should begin promptly. This means HR or a supervisor sits down with the worker, gathers information about the specific exposure and the worker's concerns, reviews available accommodations, and documents the conversation. The worker's healthcare provider may need to be involved, particularly when the nature of the risk or the appropriate accommodation requires medical input. Giving pregnant workers a clear point of contact for these conversations — ideally someone trained in both the legal framework and the practical accommodation options — removes friction from a process that can otherwise feel intimidating. Temporary reassignment and leave options are among the tools HR can use when standard accommodations are insufficient.

Accommodations for pregnant workers facing infectious disease exposure risk may include remote work arrangements, temporary reassignment to a role with lower exposure risk, modified scheduling to reduce contact with potentially infectious individuals, enhanced personal protective equipment, or temporary leave. The appropriate accommodation depends on the specific job, the nature of the infection risk, the worker's gestational stage, and any guidance from her healthcare provider. Not every accommodation will be feasible for every role, but the employer's obligation is to identify and offer accommodations that are reasonable given the circumstances, not to provide whatever the worker requests regardless of operational impact.

Managing confidentiality and communication

Infectious disease situations in the workplace create pressure to communicate — from workers wanting to know whether a colleague tested positive, from managers trying to make staffing decisions, and from the organization trying to demonstrate that it is taking safety seriously. HR's role is to manage this communication in a way that protects individual privacy while providing the information employees need to protect themselves.

Medical information about specific employees, including pregnancy status and any accommodations granted, must be kept strictly confidential. If a worker tests positive for an infectious disease, the employer may need to notify coworkers who were potentially exposed, but this notification should not identify the infected individual by name. Similarly, accommodations granted to a pregnant worker should not be disclosed to colleagues in ways that reveal the worker's pregnancy or medical situation. Violations of medical confidentiality expose the employer to liability and undermine employee trust in ways that are difficult to repair. HRMS platforms with strong confidentiality controls help ensure that sensitive accommodation records are accessible only to those with a legitimate need to know.

Training managers on their role in the response

The written policy only matters if the people who interact with pregnant workers on a daily basis know how to apply it. Manager training should cover the legal framework at a level sufficient to prevent common mistakes, the practical steps to take when a pregnant worker raises a concern, what to say and what not to say, and when to escalate to HR. Managers who attempt to handle infectious disease accommodation requests on their own, without HR involvement, often make well-intentioned decisions that create legal exposure. The goal of training is not to make managers into HR specialists but to ensure that they recognize accommodation-related conversations when they arise and bring HR in before commitments are made.

Training should also address the informal dynamics that can create liability. Comments that suggest a pregnant worker is being dramatic, that her concerns are not serious, or that the organization cannot afford to accommodate her are exactly the kind of statements that surface in litigation. Managers should understand that the appropriate response to a pregnant worker raising an infection concern is to take it seriously, document the conversation, and loop in HR — not to reassure her that everything is fine and move on.

Preparing for the next outbreak

The organizations that handled the COVID-19 pandemic best for their pregnant workers were generally those that had already thought through their infectious disease accommodation frameworks before the emergency arrived. Proactive HR planning consistently outperforms reactive crisis management across every dimension of workforce management. The time pressure and operational disruption of an active outbreak is the worst possible moment to be building policy from scratch. AI-assisted HR management tools can help organizations systematically track accommodation requests, flag potential compliance gaps, and maintain documentation that would be essential in any regulatory investigation or litigation. Building these systems during a calm period makes them available when they are genuinely needed.

Infectious disease exposures for pregnant workers sit at the intersection of employment law, public health, operational management, and employee relations. HR teams that take a proactive, policy-driven approach protect their pregnant employees, reduce legal risk, and build a reputation as an employer that takes its obligations seriously. That reputation matters for recruitment, retention, and organizational culture in ways that extend well beyond any single accommodation decision.
