Physicians and the spread of disease

Legally Reviewed by Steven R. Davis and John A. Davis Jr. on August 24, 2026

When you seek care at a hospital or clinic, you expect the medical environment to protect your health. One source of patient harm that receives far less public attention than it deserves is physician presenteeism: the practice of healthcare workers reporting for their shifts while sick with communicable illnesses. For a healthy patient, exposure to a sick care provider may mean a brief inconvenience. For a patient who is immunocompromised, recovering from surgery, or managing a serious chronic illness, that same exposure can trigger life-threatening complications.

If you or a family member developed a serious illness after exposure to a sick healthcare worker in a clinical setting, and the provider or facility failed to follow applicable infection control standards, you may have grounds for a medical malpractice claim. At Davis & Davis, Steven R. Davis and John A. Davis Jr. represent Houston-area patients harmed by all forms of healthcare negligence, including negligence connected to preventable healthcare-associated infections.

How Common Is Healthcare Worker Presenteeism?

The data on how often healthcare workers report for duty while sick is sobering. A 2023 observational study published in a peer-reviewed infection control journal found that nearly 50 percent of healthcare workers with symptomatic COVID-19 continued to work. Research on influenza presenteeism in clinical settings has found rates ranging from 14 to 68 percent depending on the specialty and local staffing culture.

The drivers of presenteeism in healthcare are well-documented. Surveys have found that as many as 95 percent of healthcare workers who came to work sick cited concern that no one would cover their shift. Approximately 99 percent reported not wanting to let their colleagues down. The culture of medicine, which trains physicians to push through discomfort and prioritize patient access, reinforces this behavior even when it puts patients at direct risk.

Healthcare facilities bear significant responsibility for this culture. When an institution lacks a clear, enforced policy on work exclusion during illness, or when the informal expectation is that clinical staff will show up regardless of their health status, the predictable result is that sick providers continue to expose vulnerable patients to communicable illness. Individual choice and institutional culture operate together, and the law may hold both accountable when a patient suffers harm.

Who Faces the Greatest Risk From Sick Healthcare Workers?

Not all patients face equal risk from exposure to a sick provider. For the following groups, an exposure that produces a mild illness in a healthy adult can escalate to a medical emergency:

• Patients recovering from surgery or major invasive procedures, whose immune systems are already taxed
• Individuals receiving chemotherapy, immunosuppressive therapy, or radiation treatment
• Elderly residents of nursing facilities and long-term care settings
• Newborns and neonates in intensive care units
• Patients with HIV, AIDS, or other conditions that impair immune function
• Individuals managing chronic conditions including diabetes, chronic kidney disease, and heart failure

Outbreaks of norovirus, influenza, and other communicable illnesses in hospital wards have been traced to infected staff members who continued working. When a patient dies from an infection contracted in this way, families may have grounds for a wrongful death claim in addition to a malpractice claim. The scale of the underlying problem is significant: research has estimated that as many as one in ten patients in acute care hospital settings will develop at least one infection during their stay. MRSA caused nearly 20,000 deaths in 2017 from approximately 120,000 total infections, a fatality rate exceeding 15 percent.

What Standards Govern Healthcare Worker Illness Policies?

Specific, authoritative guidance exists on when healthcare workers should be excluded from patient contact. The Centers for Disease Control and Prevention’s infection control guidelines for healthcare personnel establish clear expectations. Under those guidelines, healthcare workers with acute gastrointestinal illness should be excluded from patient care until they have been symptom-free for at least 48 hours. Those with active respiratory illness symptoms are expected to follow masking and distancing protocols appropriate to their clinical environment and the pathogens in circulation.

Healthcare facilities are expected to develop, communicate, and consistently enforce written policies on staff illness and work exclusion. Accreditation standards and CDC guidance collectively create a baseline expectation that institutions will take affirmative steps to prevent infected staff from exposing vulnerable patients. A facility that lacks a written policy, fails to enforce a policy it has adopted, or tolerates a culture in which sick staff routinely continue working may face independent liability for the patient harm that results.

When Presenteeism Crosses Into Medical Negligence

Not every instance of a healthcare worker showing up with mild symptoms rises to the level of medical negligence. Malpractice occurs when a provider’s conduct departs from what a reasonably careful clinician in the same circumstances would have done, and that departure causes the patient measurable harm. Several factual patterns may support a presenteeism-related malpractice claim:

• A healthcare worker with a documented, active gastrointestinal illness provided direct care to a patient with known immune compromise, and that patient subsequently contracted the same illness and suffered serious complications
• A nurse or physician worked through an influenza-like illness during an active facility outbreak, contrary to the facility’s own written work exclusion policy
• A facility knew that a provider was ill but permitted them to continue working rather than enforcing infection control protocols
• A patient contracted a healthcare-associated infection epidemiologically linked to a specific staff member whose illness was documented and known to supervisors before the patient’s exposure

Establishing these connections requires a thorough review of medical records, staffing and scheduling logs, facility infection control records, incident reports connected to the relevant outbreak, and expert testimony from an infection control specialist or physician who can explain how the applicable standard of care was breached.

Facility-Level Failures That May Create Liability

The responsibility for presenteeism-related patient harm does not fall on individual providers alone. A healthcare facility may bear independent liability when:

• No written policy exists governing staff exclusion from patient care during illness
• A written policy exists but is not consistently enforced in practice
• Management was aware that the informal culture expected staff to work regardless of illness and failed to address that culture
• Supervisors or charge nurses were aware that a specific staff member was ill and did not remove them from patient contact
• The facility’s scheduling and staffing structure created structural pressure on employees to report despite illness

In complex presenteeism cases, institutional failures often matter as much as individual provider choices. Our attorneys understand how to investigate these patterns through facility records, staffing documents, and infection control audit materials. Understanding how Davis & Davis approaches complex malpractice cases may give you a sense of whether our background is suited to your situation.

These facility-level failures connect to broader patterns of institutional negligence we also see in resident burnout cases, where hospitals allow working conditions that foreseeably lead to patient harm, and in situations where providers have concealed errors after the fact.

Proving Your Claim: What the Evidence Must Show

Presenteeism cases present unique evidentiary challenges. The chain of transmission from a sick provider to a patient’s subsequent infection is not always immediately visible in the medical record. Proving your claim typically requires:

• Medical records documenting the course of your care and the onset and progression of your infection
• Provider illness documentation, including any records indicating that the relevant provider reported symptoms or was known to be ill around the time of your exposure
• Facility infection control records, including incident reports, staffing logs, and outbreak investigation materials
• Epidemiological analysis from a qualified expert connecting the provider’s illness to your infection
• Expert medical testimony on the applicable standard of care, its breach, and the causal relationship between the breach and your harm

Texas medical malpractice cases require a preliminary expert report filed within 120 days of a defendant filing an answer. This procedural requirement means early consultation with a qualified attorney is important. The sooner you begin the process, the better positioned your legal team will be to secure the records and retain the experts your case requires.

Texas Deadlines and Your Rights

Texas law imposes a two-year statute of limitations on medical malpractice claims, generally measured from the date of the negligent act or from the date the patient discovered or reasonably should have discovered the injury. Waiting too long to consult an attorney can forfeit your right to pursue a claim regardless of the strength of the underlying facts.

If you believe a healthcare-associated infection caused you or a family member serious harm, take steps now to protect your options. Preserve all medical records you have received. Document the timeline of your care and when symptoms began. Avoid signing documents from the facility or its insurer without legal review. Then contact Davis & Davis to speak with Steven R. Davis or John A. Davis Jr. about whether your situation may support a legal claim under Texas law.
