INITIAL ALERTEmail

To the campus community, Today the University received confirmation that two students have tested positive for tuberculosis, or TB. These students have been isolated and are currently under medical supervision. HIPAA and FERPA regulations prevent us from disclosing further information about the students. Your health and safety are of the utmost importance. We have been in contact with infectious disease specialists at the DuPage County Health Department, who have initiated a contact investigation. We are making arrangements with the health department for free testing to be available on campus and are working to schedule information sessions to answer any questions you may have. We will provide more details as soon as they become available. Meanwhile, it's important that we educate ourselves, and learn what TB is and isn't. You can learn more about TB on the CDC website and in the attachment. We want you to understand that while this is a potentially serious disease, it also is preventable and treatable. In my almost nine years at Elmhurst, it's been my privilege to see how this community has responded to different challenges we've faced. Because this situation is unfamiliar to most of us, it's especially important that we be thoughtful and show care, grace and consideration during this time. Best, Troy

To our campus community, As you know, we have been working closely with the DuPage County Health Department, which has been guiding our response to the tuberculosis cases associated with our campus. With their assistance, we have already reached out to those who may have been in close contact with the affected individuals. The health department has emphasized that casual contact is generally not sufficient for transmission of TB bacteria—it is transmitted through prolonged, close contact with someone who has infectious tuberculosis. Free testing by the health department is being made available to those who were identified as potentially close contacts. If you have not received a letter but feel compelled to be tested, please visit this page. If you would like to learn more about TB and its symptoms, visit the Center for Disease Control and Prevention's website. Best, Troy

Message elements

How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

    Final assessment

    Unanimous: the message is signed by 'Troy' on behalf of 'the University,' identifying the issuer.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardpresent25/25

    Final assessment

    Unanimous: the message names tuberculosis (TB) as the specific health threat, confirmed in two students.

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationabsent0/25

    Final assessment

    Unanimous: no specific building or campus location is named, only 'the University' in general.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidanceabsent3/25

    Final assessment

    Strong majority (22 of 25): the message only describes future plans for testing and info sessions, giving recipients no protective action to take now; a small minority read the mention of free testing as actionable guidance, but the consensus is that nothing is instructed.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

    1. absent: Only mentions arranging testing/info sessions, no direct action instructed to reader.
    2. absent: No instructed protective action, only that testing will be arranged later.

    4. absent: No protective action instructed, only that testing will be arranged later.
    5. absent: No instruction to recipients beyond informational education.

    9. absent: no protective action instructed, only future testing/info sessions mentioned
    10. absent: No protective action instructed to recipients, only informational.
    11. present: Mentions free testing and info sessions, but mostly advisory; 'learn what TB is' is weak guidance, still counts as offered action.
    12. absent: No protective action instructed; only informational content about testing to come.
    13. absent: No instruction to recipients, only info about testing being arranged.
    14. absent: No instruction to recipients beyond learning about TB; testing is offered, not directed.

    Final assessment

    Unanimous: 'Today the University received confirmation' establishes clear recency.

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

  • Impactpresent25/25

    Final assessment

    Unanimous: the message calls TB 'a potentially serious disease,' conveying severity even while noting it is treatable.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.

About this analysis
Context

Background

Tuberculosis on a small residential campus poses distinct contact-tracing challenges because students share classrooms, dining, and housing densely. On Halloween night 2024, Elmhurst University President Troy VanAken alerted the community to a confirmed TB case with additional cases under evaluation; the Chicago Sun-Times reported that the school partnered with the DuPage County Health Department on contact tracing and free testing. FOX 32 Chicago later confirmed two students with TB. The university built a standing TB info page to centralize guidance. The case is a useful counterpart to the same-month Georgetown TB notice, showing how a small private university and a large research university handled the same disease with the same proportionate, county-led playbook.
Analysis

Key Findings

The notice came directly from the university president on Halloween night, signaling urgency at a small residential campus
Two students were confirmed with TB; the DuPage County Health Department traced the first case to October 17, 2024, and accounts differ on whether the Halloween-night email described one confirmed case with others under evaluation (ABC7) or two confirmed students (The Leader, Patch)
Free on-campus testing was offered to identified close contacts, converting the alert into immediate logistics
Messaging stressed the active-versus-latent distinction to counter the misconception that any exposure means infection
Outcome
Two students were ultimately confirmed with TB. Close contacts were provided free testing while the county health department conducted contact tracing; the university posted ongoing TB information and resources for the community.
