Only 9.6% of Hospital Staff Asked About Bird Flu Exposure in Drills

During unannounced visits conducted from January through June 2026 across urgent care centers, hospital outpatient clinics, and emergency departments, reception staff inquired about potential exposure to dead or sick livestock, birds, or other mammals in just 7 out of 73 drills, representing 9.6%. The unannounced mystery patient visits tested whether facilities across three jurisdictions could recognize a possible avian influenza A(H5) infection and prevent it from spreading in crowded waiting rooms during flu season. The findings come from a Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report published October 1, 2026.

How 73 Mystery Patient Drills Tested Facility Preparedness Across Four Regions

The 73 drills took place at 69 medical facilities from January through June 2026. Virgin Islands. Forty-two drills took place in emergency departments, 19 in hospital outpatient clinics, and 12 in urgent care centers.

The New York City Health Department ran the drills alongside the Regional Emerging Special Pathogen Treatment Center at NYC Health + Hospitals/Bellevue, which announced the voluntary program in April 2026. Portraying individuals aged 20 to 28 who developed a cough, fever, muscle aches, and pink eye after attempting to help an unwell duck in Central Park unprotected by gloves, performers from the NYU Standardized Patient Program executed the visits. Makeup, petroleum jelly, and eye drops mimicked conjunctivitis. When staff asked about sick contacts, the actor replied, Does a sick bird count?

Where Front Desk Screening Met Isolation and Protective Gear Gaps

Staff screened for general symptoms in 93.2% of drills and asked about travel history in 79.5% of visits. Actors received a mask in 82.2% of drills at a median of two minutes after arrival, though only 43.1% of timed drills met the one-minute target. Isolation was less reliable: actors moved to an isolation room in 71.2% of drills after a median duration of 11 minutes, and under half of those transfers achieved the 10-minute objective. Only 23 of the 52 placements involved negative-pressure airborne infection isolation rooms. Overall, 44 drills, or 60.3%, counted as successful because the patient was both masked and isolated.

Protective equipment showed the clearest gap among clinicians. Out of 68 clinician encounters, providers wore all required gear—gloves, mask, gown, and eye protection—in only 25% of visits, and wore none in 5.9%. Urgent care clinicians wore full protective equipment in just one of 12 drills. In 63.4% of the exercises, personnel recognized that the participant faced an avian influenza risk, and notification of the health department occurred or would have occurred in 49.3% of the evaluations.

Why Missing Exposure Questions Can Alter H5 Diagnosis Outcomes

H5 infection shares symptoms with ordinary respiratory illnesses and has no unique indicator. CDC guidance for clinicians evaluating possible H5N1 patients lists eye redness, fever, cough, sore throat, body aches, and shortness of breath. Without asking about contact with birds, dairy cattle, or other animals, a clinician may skip the specialized testing performed by public health laboratories and the CDC. The report authors noted that exposure-specific questions unique to avian influenza were asked considerably less often than general symptom or travel history inquiries. Clinicians performed better once inside the exam room, asking about sick or dead birds, livestock, or other mammals in 60.7% of the 61 drills where exposure questions were raised.

Security guards, receptionists, or registrars met the actor first in 69.9% of drills. Competency-based, role-tailored infection prevention and control education could help both frontline public-facing employees and clinical personnel, according to the publication’s creators. The evaluation came with explicit limits, as not every hospital in the region participated, few clinics and urgent care centers were tested, actors could not show an actual fever, and some staff may have recognized the drill. The CDC situation summary counted 71 confirmed and probable human H5 cases in the United States since February 2024 as of its March 6, 2026 update, affecting dairy and poultry workers. The CDC maintains that the current public health risk is low while noting that people with close or prolonged contact with infected animals face greater risk.
