Measles Outbreak Associated with a Migrant Shelter - Chicago, Illinois, February-May 2024.

Measles, a highly contagious respiratory virus with the potential to cause severe complications, hospitalization, and death, was declared eliminated from the United States in 2000; however, with ongoing global transmission, infections in the United States still occur. On March 7, 2024, the Chicago Department of Public Health (CDPH) confirmed a case of measles in a male aged 1 year residing in a temporary shelter for migrants in Chicago. Given the congregate nature of the setting, high transmissibility of measles, and low measles vaccination coverage among shelter residents, measles virus had the potential to spread rapidly among approximately 2,100 presumed exposed shelter residents.

Community Transmission of SARS-CoV-2 Associated with a Local Bar Opening Event - Illinois, February 2021.

During February 2021, an opening event was held indoors at a rural Illinois bar that accommodates approximately 100 persons. The Illinois Department of Public Health (IDPH) and local health department staff members investigated a COVID-19 outbreak associated with this opening event. Overall, 46 COVID-19 cases were linked to the event, including cases in 26 patrons and three staff members who attended the opening event and 17 secondary cases.

The Minimal Clinically Important Difference in Glaucoma Medication Adherence: Interviews of Glaucoma Experts.

Poor adherence to glaucoma medications is associated with progressive vision loss. While many interventions have sought to increase glaucoma medication adherence, the amount by which adherence must increase to have a clinically significant effect remains unknown. To generate a hypothesized minimal clinically important difference (MCID) for glaucoma medication adherence, we conducted interviews with glaucoma experts.

Amikacin exposure and susceptibility of macrolide-resistant .

is associated with antibiotic resistance and poor treatment outcomes. We described within-patient changes in resistance to clarithromycin and amikacin. Patients with amikacin exposure and a >50-month interval between isolates were identified.

Epidemiology of Nontuberculous Mycobacteriosis.

Annual prevalence estimates for pulmonary nontuberculous mycobacterial (PNTM) disease in the contiguous United States range from 1.4 to 13.9 per 100,000 persons, while one study found an annual prevalence of up to 44 per 100,000 persons in Hawaii.

Norovirus, astrovirus, and sapovirus among immunocompromised patients at a tertiary care research hospital.

We estimated the prevalence of astrovirus, sapovirus, and norovirus among patients enrolled in research protocols and receiving medical care at the Clinical Center of the National Institutes of Health, Bethesda, MD, a clinical research hospital with a large immunocompromised patient population. We identified patients whose fecal specimens were submitted to the Clinical Center for testing on the Biofire FilmArray Gastrointestinal Panel from September 15, 2015 through November 30, 2016. Among 442 patients with fecal specimens submitted for multiplex testing, 11% had norovirus identified, 2% had astrovirus, and 2% had sapovirus.
