Continued spread of monkeypox in Nigeria might lead to additional sporadic cases imported to the United States. Lessons learned from this investigation might help clinical and public health authorities plan for future cases. As monkeypox cases continue to be identified in Nigeria, occasional imported cases might occur in the United States. Diagnosis, treatment, contact tracing and monitoring, infection control, decontamination of potentially contaminated surfaces, and investigation of the source were important aspects of this investigation. This report explains the challenges investigators faced responding to a single case of monkeypox and outlines lessons learned that health departments and clinicians can use to inform preparedness planning if more cases occur. This event serves as a reminder that infectious diseases are increasingly appearing in parts of the world where they are not normally found.

- SARS-CoV-2 Omicron Variant Infection in 10 Persons Within 90 Days of Previous SARS-CoV-2 Delta Variant Infection — Four States, October 2021–January 2022A new study identified 10 people with COVID-19 reinfections that occurred less than 90 days after the initial infection. While eligible vaccination status varied, the majority of reinfection cases happened among people who were not up to date with vaccinations. To best protect against reinfection and spread, all eligible people should stay up to date with their vaccinations, including a booster dose for those who are eligible, and retest if they are exposed to COVID-19 or have symptoms. To better understand COVID-19 reinfections while the Omicron variant was circulating, investigators identified people with COVID-19 reinfections that occurred within 90 days of initial infection. Ten reinfections were confirmed through whole genome sequencing at both time points. These reinfections occurred 23–87 days after the initial infection. While vaccination status varied, most of the eligible patients were not up to date on vaccinations and had high rates of close contact in school, health care, and congregate settings. Although the virus that causes COVID-19 might change as new variants emerge, vaccination remains the safest and most effective strategy to prevent severe outcomes of future COVID-19 infections.
- Enteropathogenic Escherichia coli Outbreak in a Child Care Center — Oregon, August 2021Although most strains of Escherichia coli (E. coli) are harmless, enteropathogenic E. coli (EPEC) can cause illness. This report describes the first EPEC outbreak detected in Oregon. With the advent of tests to detect multiple gastrointestinal pathogens, more EPEC outbreaks are likely to be detected. On August 16, 2021, the Oregon Public Health Division (OPHD) was notified of two pediatric cases of Shiga toxigenic E. coli (STEC) among members of the same household. One patient, aged 2 years, had attended an in-home child care center. OPHD visited the child care center on August 18 and attempted to collect clinical information on gastrointestinal symptoms and stool specimens from all staff and children with parental consent. Among 21 respondents (17 children and four staff) who provided clinical information, six of 17 children and one of four staff members reported diarrhea, vomiting, or other gastrointestinal symptoms. Stool specimens were collected from 18 people, and 12 were acceptable for testing. Nine specimens contained evidence of an enteric pathogen, including seven with EPEC, four with norovirus, and one each with rotavirus, sapovirus, astrovirus, and Campylobacter. Four were coinfected with more than one pathogen. None had evidence of STEC infection. After reviewing laboratory results, the local health officer recommended temporarily closing the center for 7 days, the child care center complied, and no more cases were reported.
