INITIAL ALERTEmail
Approximate reconstructionAmerican University Student Affairs notice (text reconstructed from the AU notice and The Eagle reporting)680 chars
The DC Department of Health (DC Health) has informed American University that a residential undergraduate student has been diagnosed with tuberculosis (TB). DC Health is leading the public health response, including contact tracing, and will directly notify any individuals who may have been exposed and need testing. If you are not contacted by DC Health, you are not considered to have been exposed and no action is needed. TB is a bacterial infection that spreads through the air when a person with active TB coughs, speaks or sings. Most people who are exposed do not become infected, and those who are infected can be treated. The student is receiving care and is doing well.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

The notice assigns the lead role to DC Health and uses an exposure-gating line ('If you are not contacted by DC Health... no action is needed') to prevent worried-well overload of the health center.
TB transmission is described precisely as airborne via 'coughs, speaks or sings,' a contrast with the surface-and-vaccine framing used in measles and meningitis notices.
Stating that the student 'is doing well' both reassures the community and signals the case is being managed, reducing speculation about a residential outbreak.

Approximate reconstructionAmerican University follow-up notice (reconstructed from AU's TB update page)448 chars
Update on TB testing for close contacts: DC Health has identified the individuals who may have been exposed and is arranging testing for those close contacts. Testing for the campus community at large is not recommended, because only people identified as close contacts are considered at risk. If you have been contacted by DC Health, please follow their instructions for testing. Students may also contact the Student Health Center with questions.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

The follow-up narrows the action set even further, explicitly telling the general campus that broad testing is 'not recommended' — a deliberate effort to keep the response proportional to actual risk.
By mid-November the response had shifted from notification to logistics: arranging testing for the defined close-contact list rather than expanding the alert.
Directing remaining questions to the Student Health Center keeps the messaging consistent and reduces the rumor flow common in residential settings.
Context

Background

Tuberculosis remains a notifiable disease handled jointly by universities and local health authorities. In this November 2021 case, American University announced that a residential undergraduate had been diagnosed with TB and that the DC Department of Health was leading contact tracing. The student newspaper The Eagle reported that DC Health experts joined AU health officials and that the agency would directly notify anyone needing testing. The case echoed a separate July 2018 AU TB diagnosis involving an off-campus graduate student, but the 2021 case was distinct in involving a residential undergraduate and a campuswide notice. The episode is a model of proportionate public-health messaging: an alert that informs the whole community while narrowly defining who must actually take action.
Analysis

Key Findings

The notice repeatedly gated action to people directly contacted by DC Health, preventing the worried-well from overwhelming testing resources
TB transmission was described as airborne via coughing, speaking, or singing — distinct from the vaccine framing of measles/meningitis notices
DC Health, not the university, held the lead public-health role including contact tracing and notification
The case is distinct from a separate July 2018 AU TB case involving an off-campus graduate student
Outcome
DC Health determined who required testing based on exposure level and directly contacted close contacts. The university emphasized that most people exposed to TB do not develop active disease and that the risk to the broader community was low.
