Purpureocillium lilacinum Keratitis Outbreak Associated with an Ophthalmology Clinic - New York City, 2024 [Case Report]

Chang, Michelle E; Mantell, Elise; Greendyke, William G; Schwem, Brian; Mudge, Zachary; López, Luisa F; Smith, Dallas J; Litvintseva, Anastasia P; Rowh, Adam; Moulton-Meissner, Heather; Gable, Paige; McPherson, Tristan D
In December 2024, a clinical laboratory notified the New York City Health Department of three patients with fungal keratitis caused by an unidentified mold following laser eye surgery at an ophthalmology clinic. All three patients experienced vision loss, and one patient required corneal transplantation. Corneal cultures from two of the patients grew Purpureocillium lilacinum, an environmental mold that can cause a range of infections in humans; eye infections have been reported. The clinic paused surgeries. The health department assessed the clinic's infection prevention and control (IPC) practices and identified multiple deficiencies, including incomplete instrument sterilization logs, absence of disinfectants approved for use on work surfaces, use of expired topical ocular medications, and opportunities for exposure to nonsterile water from cool-mist humidifiers in the procedure room. CDC environmental infection control guidelines recommend avoidance of cool-mist humidifiers in health care facilities. All environmental cultures were negative for P. lilacinum, but fungal amplicon sequencing detected P. lilacinum DNA in the tubing of a surgical device. No further cases were identified after implementation of recommended IPC measures and resumption of surgeries during January 2025. Adherence to published IPC guidance during all procedures in ambulatory settings can reduce the risk for health care-associated infections.

Leocadio, Ciarra; Garcia, Elizabeth; Lash, Maura; Berardi, Jonathan; Chan, Justin; Chasan, Rachel; Esquivel, Blanca; Foote, Mary; Glesby, Marshall J; Guerra, Amiyah; Harris, Alexander B; Knutsen, Dorothy; Mannheimer, Sharon; Mazo, Dana; McLean, Jacob; McPherson, Tristan; Meyerowitz, Eric; Mgbako, Ofole; Patel, Gopi; Pagán Pirallo, Patricia M; Radix, Asa E; Riska, Paul; Sayegh, Mark; Seifu, Leah; Shaw, Raphael; Zingman, Barry; Zomorodi, Rustin; Zucker, Jason; Wong, Marcia
BACKGROUND:There is emerging literature describing clinical characteristics and outcomes in patients with mpox treated with tecovirimat. METHODS:We analyzed retrospective deidentified data from healthcare systems in New York City with the highest number of tecovirimat prescriptions. Individuals with probable or confirmed mpox initiating tecovirimat from May-December 2022 were included. A chart abstraction instrument was used to extract demographic and clinical data from medical records. We examined factors associated with delay in treatment and hospitalization. RESULTS:A total of 708 individuals prescribed tecovirimat for mpox were included in the analysis; median age was 36 years (IQR 31-43); 566 (80%) were cisgender men who have sex with men; and 399 (56%) were living with HIV. Side effects (100, 14%) and severe adverse events (7, 1%) were rare. The most common long-term sequela was scarring (69, 10%). One hundred and one (14%) were hospitalized. Median time from symptom onset to treatment initiation was 8 days (IQR 6-11). Non-Hispanic Black patients had higher risk of initiating tecovirimat ≥8 days after symptom onset (relative risk [RR]=1.3, 95%CI: 1.2-1.7) and being hospitalized (adjusted relative risk [aRR]=2.2, 95%CI: 1.4-3.5) compared with Hispanic patients, after adjusting for HIV and insurance status. CONCLUSIONS:We described common reasons for tecovirimat initiation and hospitalization. There were racial inequities in hospitalization and treatment delays. More research and focused efforts to mitigate these inequities are needed. These findings may better inform decisions for treatment initiation and hospitalization for mpox.

Progression from Candida (Candidozyma) auris colonization to bloodstream infection, New York State (NYS) and Chicago

Southwick, Karen; Ostrowsky, Belinda; Quinn, Monica; McPherson, Tristan; Perez, Stephen; Greenko, Jane; Bucher, Coralie; Haley, Valerie; Fernandez, Rafael; Walblay, Kelly; Kogut, Sarah; Lutterloh, Emily
In 2 cohorts of patients colonized with Candida auris in New York State and Chicago, those who progressed to C auris bloodstream infection had comorbidities, including respiratory failure and mechanical ventilation, cocolonization with multidrug-resistant organisms, and extensive health care facility admissions, devices, and procedures. Fewer had traditional risk factors for candidemia (e.g. hematological malignancy, immunosuppression). Secondary prevention efforts are essential, including avoiding unnecessary device use and ensuring meticulous device maintenance and equipment cleaning and disinfection.

Public reporting guidelines for outbreak data: Enabling accountability for effective outbreak response by developing standards for transparency and uniformity

Grégoire, V; Zhu, A W; Brown, C M; Brownstein, J S; Cardo, D; Cumming, F; Danila, R; Donnelly, C A; Duchin, J S; Fill, M A; Fullerton, K; Funk, S; George, D; Hopkins, S; Kraemer, M U G; Layton, M; Lessler, J; Lynfield, R; McCaw, J M; McPherson, T D; Moore, Z; Morgan, O; Riley, S; Rosenfeld, R; Samoff, E; Schaffner, W; Shaffner, J; Sturm, R; Terashita, D; Walke, H; Washington, R E; Rivers, C M
OBJECTIVES/OBJECTIVE:There are few standards for what information about an infectious disease outbreak should be reported to the public and when. To address this problem, we undertook a consensus process to develop recommendations for what epidemiological information public health authorities should report to the public during an outbreak. STUDY DESIGN/METHODS:We conducted a Delphi study following the steps outlined in the ACcurate COnsensus Reporting Document (ACCORD) for health-related activities or research. METHODS:We assembled a steering committee of nine experts representing federal and state public health, academia, and international partners to develop a candidate list of reporting items. We then invited 45 experts, 35 of whom agreed to participate in a Delphi panel. Of those, 25 participated in voting in the first round, 25 in the second round, and 25 in the third round, demonstrating consistent engagement in the consensus-building process. The final stage of the Delphi process consisted of a hybrid consensus meeting to finalize the voting items. RESULTS:The Delphi process yielded nine core reporting items representing a minimum standard for public outbreak reporting: numbers of new confirmed cases, new hospital admissions, new deaths, cumulative confirmed cases, cumulative hospital admissions, and cumulative deaths, each reported weekly and at Administrative Level 1 (typically state or province), and stratified by sex, age group, and race/ethnicity. CONCLUSIONS:This minimum reporting standard creates a strong framework for uniform sharing of outbreak information and promotes consistency of data between jurisdictions, enabling effective response by promoting access to information about an unfolding epidemic.

Lash, Maura K; Latham, Ned H; Chan, Pui Ying; Foote, Mary M K; Garcia, Elizabeth A; Silverstein, Matthew F; Wong, Marcia; Alexander, Mark; Alroy, Karen A; Bajaj, Lovedeep; Chen, Kuan; Howard, James Steele; Jones, Lucretia E; Lee, Ellen H; Watkins, Julian L; McPherson, Tristan D
We assessed tecovirimat treatment equity for 3,740 mpox patients in New York, New York, USA, during the 2022 mpox emergency; 32.4% received tecovirimat. Treatment rates by race/ethnicity were 38.8% (White), 31.3% (Black/African American), 31.0% (Hispanic/Latino), and 30.1% (Asian/Pacific Islander/other). Future public health emergency responses must prioritize institutional and structural racism mitigation.

Implementation and early outcomes of a telehealth visit model to deliver tecovirimat for mpox infection in New York City

Chan, Justin; DiTullio, David J; Pagan Pirallo, Patricia; Foote, Mary; Knutsen, Dorothy; Kottkamp, Angelica Cifuentes; McPherson, Tristan D; Mukherjee, Vikramjit; Pitts, Robert; Wallach, Andrew; Wong, Marcia; Mazo, Dana; Mgbako, Ofole
The 2022 mpox outbreak in New York City posed challenges to rapidly scaling up treatment capacity. We describe a telehealth treatment model launched during this outbreak that facilitated healthcare provider treatment capacity, and was able to adhere to a Centers for Disease Control and Prevention (CDC)-sponsored expanded access investigational new drug (EA-IND) protocol for tecovirimat. Sixty-nine patients were evaluated and prescribed tecovirimat for mpox through telehealth visits at NYC Health + Hospitals/Bellevue and NYU Langone Health from June to August 2022. Thirty-two (46.4%) were previously diagnosed with HIV. Forty-four (63.8%) reported full recovery, with the remainder lost to follow-up. Most patients (n = 60, 87.0%) attended at least one follow-up visit (either in person or through telehealth) after starting treatment. We observed favorable treatment outcomes, with no serious adverse events, hospitalizations, or deaths related to mpox. While equitable access to telehealth remains a limitation that needs to be addressed, this telehealth model enabled a rapid scale-up of tecovirimat prescription during the mpox outbreak, and should be considered as an important tool used to respond to future infectious disease outbreaks.
