COVID-19 Mortality Among American Indian and Alaska Native Persons - 14 States, January-June 2020.

American Indian/Alaska Native (AI/AN) persons experienced disproportionate mortality during the 2009 influenza A(H1N1) pandemic (1,2). Concerns of a similar trend during the coronavirus disease 2019 (COVID-19) pandemic led to the formation of a workgroup* to assess the prevalence of COVID-19 deaths in the AI/AN population. As of December 2, 2020, CDC has reported 2,689 COVID-19-associated deaths among non-Hispanic AI/AN persons in the United States.† A recent analysis found that the cumulative incidence of laboratory-confirmed COVID-19 cases among AI/AN persons was 3.5 times that among White persons (3). Among 14 participating states, the age-adjusted AI/AN COVID-19 mortality rate (55.8 deaths per 100,000; 95% confidence interval [CI] = 52.5-59.3) was 1.8 (95% CI = 1.7-2.0) times that among White persons (30.3 deaths per 100,000; 95% CI = 29.9-30.7). Although COVID-19 mortality rates increased with age among both AI/AN and White persons, the disparity was largest among those aged 20-49 years. Among persons aged 20-29 years, 30-39 years, and 40-49 years, the COVID-19 mortality rates among AI/AN were 10.5, 11.6, and 8.2 times, respectively, those among White persons. Evidence that AI/AN communities might be at increased risk for COVID-19 illness and death demonstrates the importance of documenting and understanding the reasons for these disparities while developing collaborative approaches with federal, state, municipal, and tribal agencies to minimize the impact of COVID-19 on AI/AN communities. Together, public health partners can plan for medical countermeasures and prevention activities for AI/AN communities.

Extrapulmonary Nontuberculous Mycobacterial Disease Surveillance - Oregon, 2014-2016.

Nontuberculous mycobacteria (NTM), ubiquitous in soil and water, usually infect immunocompromised persons. However, even healthy persons are susceptible to infection through percutaneous inoculation. Although 77% of NTM diseases manifest as primarily pulmonary illnesses (1), NTM also infect skin, bones, joints, the lymphatic system, and soft tissue. NTM infections can have incubation periods that exceed 5 years (2), often require prolonged treatment, and can lead to sepsis and death. Extrapulmonary NTM outbreaks have been reported in association with contaminated surgical gentian violet (3), nail salon pedicures (4), and tattoos received at tattoo parlors (5), although few surveillance data have been available for estimating the public health burden of NTM.* On January 1, 2014, the Oregon Health Authority designated extrapulmonary NTM disease a reportable condition. To characterize extrapulmonary NTM infection, estimate resources required for surveillance, and assess the usefulness of surveillance in outbreak detection and investigation, 2014-2016 extrapulmonary NTM surveillance data were reviewed, and interviews with stakeholders were conducted. During 2014-2016, 134 extrapulmonary NTM cases (11 per 1 million persons per year) were reported in Oregon. The age distribution was bimodal, with highest incidence among persons aged <10 years (20 per 1 million persons per year) and persons aged 60-69 years (18 per 1 million persons per year). The most frequently reported predisposing factors (occurring within 14-70 days of symptom onset) were soil exposure (41/98; 42%), immunocompromised condition (42/124; 34%), and surgery (32/120; 27%). Overall, 43 (33%) patients were hospitalized, 18 (15%) developed sepsis, and one (0.7%) died. Surveillance detected or helped to control two outbreaks at low cost. Jurisdictions interested in implementing extrapulmonary NTM surveillance can use the Council of State and Territorial Epidemiologists (CSTE) standardized case definition (6) for extrapulmonary NTM reporting or investigative guidelines maintained by the Oregon Health Authority (7).

Notes from the Field: Shigellosis Outbreak Among Men Who Have Sex with Men and Homeless Persons - Oregon, 2015-2016.

In July 2015, Shigella sonnei infections with a specific pulsed-field gel electrophoresis (PFGE) pattern linked to a multistate outbreak were recognized among men who have sex with men (MSM) in the Portland metropolitan area, and an outbreak investigation was initiated. During November 2015, isolates with PFGE patterns indistinguishable from the outbreak strain were identified in cases reported in four women, none of whom had epidemiologic links to other affected persons; however, three reported homelessness. In the ensuing months, additional S. sonnei infections were reported among homeless persons in the Portland area.

Escherichia coli O157:H7 infections associated with consumption of locally grown strawberries contaminated by deer.

BACKGROUND: An outbreak of Escherichia coli O157:H7 was identified in Oregon through an increase in Shiga toxin-producing E. coli cases with an indistinguishable, novel pulsed-field gel electrophoresis (PFGE) subtyping pattern. METHODS: We defined confirmed cases as persons from whom E. coli O157:H7 with the outbreak PFGE pattern was cultured during July-August 2011, and presumptive cases as persons having a household relationship with a case testing positive for E. coli O157:H7 and coincident diarrheal illness. We conducted an investigation that included structured hypothesis-generating interviews, a matched case-control study, and environmental and traceback investigations. RESULTS: We identified 15 cases. Six cases were hospitalized, including 4 with hemolytic uremic syndrome (HUS). Two cases with HUS died. Illness was significantly associated with strawberry consumption from roadside stands or farmers' markets (matched odds ratio, 19.6; 95% confidence interval, 2.9-∞). A single farm was identified as the source of contaminated strawberries. Ten of 111 (9%) initial environmental samples from farm A were positive for E. coli O157:H7. All samples testing positive for E. coli O157:H7 contained deer feces, and 5 tested farm fields had ≥ 1 sample positive with the outbreak PFGE pattern. CONCLUSIONS: The investigation identified fresh strawberries as a novel vehicle for E. coli O157:H7 infection, implicated deer feces as the source of contamination, and highlights problems concerning produce contamination by wildlife and regulatory exemptions for locally grown produce. A comprehensive hypothesis-generating questionnaire enabled rapid identification of the implicated product. Good agricultural practices are key barriers to wildlife fecal contamination of produce.

Family history of colorectal cancer: clinicians' preventive recommendations and patient behavior.

Few population-based studies have addressed the role that family history of colorectal cancer (CRC) plays in clinician decision making or patient health choices. The objective of this study was to evaluate the effect of family history of CRC on clinician practice, patient CRC screening, and patient preventive behavior. We analyzed 2008 Oregon Behavioral Risk Factor Surveillance System data to examine associations between family history of CRC and 1) patient-reported clinician recommendations, 2) perceived risk of developing CRC, 3) adoption of preventive and screening behaviors, and 4) CRC risk factors among 1,795 respondents without CRC. A family history of CRC was positively associated with a higher likelihood of respondents reporting that their clinicians discussed colorectal cancer screening (OR, 4.2; 95% CI, 2.4-7.4) and of respondents having colorectal screening within the recommended time period (OR, 2.2; 95% CI, 1.3-3.9). A family history of CRC was also associated with respondents reporting lifestyle changes to prevent CRC (OR, 2.6; 95% CI, 1.7-4.0). A family history of CRC may prompt clinicians to recommend screening and preventive behavior changes and motivate patients to adopt such strategies.

Case report: Persistent shedding of a live vaccine-derived rubella virus in a young man with severe combined immunodeficiency and cutaneous granuloma.

A young man with X-linked severe combined immunodeficiency developed a persistent vaccine-derived rubella virus (VDRV) infection, with the emergence of cutaneous granulomas more than fifteen years after receipt of two doses of measles-mumps-rubella (MMR) vaccine. Following nasopharyngeal swab (NP) collection, VDRV was detected by real-time polymerase chain reaction (RT-qPCR) and sequencing, and live, replication-competent VDRV was isolated in cell culture. To assess duration and intensity of viral shedding, sequential respiratory samples, one cerebrospinal fluid sample, and two urine samples were collected over 15 months, and VDRV RNA was detected in all samples by RT-qPCR. Live VDRV was cultured from nine of the eleven respiratory specimens and from one urine specimen. To our knowledge, this was the first reported instance of VDRV cultured from respiratory specimens or from urine. To assess potential transmission to close contacts, NP specimens and sera were collected from all household contacts, all of whom were immunocompetent and previously vaccinated with MMR. VDRV RNA was not detected in any NP swabs from the contacts, nor did serologic investigations suggest VDRV transmission to any contacts. This report highlights the need to understand the prevalence and duration of VDRV shedding in granuloma patients and to estimate the risk of VDRV transmission to immune and non-immune contacts.

Influence of family history of diabetes on health care provider practice and patient behavior among nondiabetic Oregonians.

INTRODUCTION: People with a family history of diabetes are at increased risk of developing diabetes; however, the effect of family history of diabetes on health care provider practice and patient behavior has not been well defined. METHODS: We analyzed data from the 2005 Oregon Behavioral Risk Factor Surveillance System, a state-based, random-digit-dialed telephone survey, to evaluate, among people with diabetes, associations between family history of diabetes and 1) patients' reports of health care provider practices, 2) patients' perceived risk of developing diabetes, and 3) patients' behaviors associated with an increased risk of developing diabetes. RESULTS: Compared with respondents at average risk, respondents with a positive family history (strong or moderate familial risk for diabetes) were more likely to report that their health care provider collects family history information about diabetes, discusses the risk of developing diabetes or other chronic conditions, and makes recommendations to change their diet or exercise behaviors to reduce the chance of developing diabetes. Respondents with a strong family history of diabetes were 5 times more likely to be very or somewhat worried about developing diabetes than were people at average risk (odds ratio [OR], 5.0; 95% confidence interval [CI], 4.0-6.2). Compared with respondents at average risk, respondents with a strong family history were more likely to report making changes in diet and exercise (OR, 1.7; 95% CI, 1.4-2.1). CONCLUSION: Integrating family history of diabetes into clinical practice offers opportunities to improve the effectiveness of diabetes detection and to promote interventions aimed at preventing or delaying the development of diabetes in people at high risk.

An investigation of Salmonella Fluntern illnesses linked to leopard geckos-United States, 2018.

Reptile contact can result in zoonotic non-typhoidal salmonellosis. In April 2018, Oregon Public Health Division contacted CDC about a cluster of four Salmonella serovar Fluntern (SF) illnesses in four states (OR, CA, IA, NY); patients reported contact with geckos, a popular reptile pet. PulseNet, the national molecular subtyping network of food-borne disease surveillance, subsequently identified additional SF clinical isolates. Twelve cases in 11 states were identified; median age was 5 years (range: <1-58 years). Three patients were hospitalized; no deaths were reported. Of those with exposure information (n = 10), all reported reptile exposure; 9 (90%) specified contact with leopard geckos. No common source of geckos was identified from reported purchase locations. Los Angeles County (LAC) health officials isolated SF from one patient's leopard gecko. Five reptile/gecko isolates were identified from the USDA National Veterinary Services Laboratories (NVSL) from 2015 to 2018. Five countries responded to an Epidemic Intelligence Information System post by PulseNet; reptile isolate sequence data were received from Czech Republic. A clinical case from England was identified through the National Center for Biotechnology Information pathogen detection pipeline; the patient did not report contact with leopard geckos. Whole genome sequencing analysis revealed substantial genetic diversity between clinical and animal isolates; however, gecko and clinical isolates from LAC were highly related (1 allele difference). This investigation linking SF illnesses to leopard geckos highlights an important public health risk from pets. A better understanding of how geckos are distributed by the pet industry in the United States could improve traceability to points of origin and mitigate Salmonella transmission at gecko breeders. Earlier NVSL reports of SF isolates from geckos suggest the risk of human SF infection from geckos is not new. This investigation demonstrates a need to educate gecko breeders, retailers and gecko owners about the continued Salmonella infection risk from pet geckos.

Association of Group B Meningococcal Vaccine Receipt With Reduced Gonorrhea Incidence Among University Students.

This case-control study examines reported cases of gonorrhea among recipients of meningococcal group B vaccine at 2 universities in Oregon.

Evaluation of Mass Vaccination Clinics in Response to a Serogroup B Meningococcal Disease Outbreak at a Large, Public University-Oregon, 2015.

PURPOSE: Between January and May 2015, seven people at a large, public university developed invasive serogroup B meningococcal disease. One case was fatal. Attack rates were highest among freshmen and members of sororities, and fraternities (Greek organizations). Mass vaccination clinics using newly licensed serogroup B vaccine were held in March, May, and October 2015. No cases occurred after the second mass vaccination clinic. METHODS: We surveyed vaccine recipients at each clinic from March to October 2015 to determine preferred methods for notification about vaccination clinics, assess motivations for attending, and evaluate the clinic attendee population. RESULTS: Vaccination rates were low; 15% of undergraduates received one vaccine dose. An additional 11% received two doses of the three-dose MenB-FHbp series, and 4% completed a serogroup B meningococcal vaccine series at a mass vaccination clinic. University freshmen were 2.3 times as likely (confidence interval: 2.2-2.9) and Greek members 1.3 times as likely (confidence interval: 1.2-1.4) to attend a mass vaccination clinic as nonfreshmen or non-Greek members, respectively. Attendees reported e-mail as their preferred communication method (90%). Concerns about developing meningococcal disease (66%) and parental request (56%) were the most commonly cited motivations for attending a vaccination clinic. CONCLUSIONS: The serogroup B meningococcal outbreak at this large, public university disproportionately affected freshmen and students affiliated with Greek organizations. Despite low overall vaccination rates, the vaccination campaign did reach the populations at risk. In future outbreaks at large universities, we recommend focusing vaccination efforts on specific at-risk populations to maximize vaccination of those most at risk for this deadly disease.

Heavy precipitation as a risk factor for shigellosis among homeless persons during an outbreak - Oregon, 2015-2016.

OBJECTIVES: Shigella species are the third most common cause of bacterial gastroenteritis in the United States. During a Shigella sonnei outbreak in Oregon from July 2015 through June 2016, Shigella cases spread among homeless persons with onset of the wettest rainy season on record. METHODS: We conducted time series analyses using Poisson regression to determine if a temporal association between precipitation and shigellosis incidence existed. Models were stratified by housing status. RESULTS: Among 105 infections identified, 45 (43%) occurred in homeless persons. With increasing precipitation, cases increased among homeless persons (relative risk [RR] = 1.36 per inch of precipitation during the exposure period; 95% confidence interval [CI] = 1.17-1.59), but not among housed persons (RR = 1.04; 95% CI 0.86-1.25). CONCLUSIONS: Heavy precipitation likely contributed to shigellosis transmission among homeless persons during this outbreak. When heavy precipitation is forecast, organizations working with homeless persons could consider taking proactive measures to mitigate spread of enteric infections.

Changes in Influenza Vaccination Rates After Withdrawal of Live Vaccine.

BACKGROUND: Before the start of the 2016-2017 influenza season, the Advisory Committee on Immunization Practices withdrew its recommendation promoting the use of live attenuated influenza vaccines (LAIVs). There was concern that this might lessen the likelihood that those with a previous LAIV would return for an injectable influenza vaccine (IIV) and that child influenza immunization rates would decrease overall. METHODS: Using Oregon's statewide immunization registry, the ALERT Immunization Information System, child influenza immunization rates were compared across the 2012-2013 through 2016-2017 seasons. Additionally, matched cohorts of children were selected based on receipt of either an LAIV or an IIV during the 2015-2016 season. Differences between the IIV and LAIV cohorts in returning for the IIV in the 2016-2017 season were assessed. RESULTS: Overall, influenza immunization rates for children aged 2 to 17 years were unchanged between the 2015-2016 and 2016-2017 seasons. Children aged 3 to 10 with a previous IIV were 1.03 (95% confidence interval, 1.02 to 1.04) times more likely to return for an IIV in 2016-2017 than those with a previous LAIV, whereas children aged 11 to 17 years with a previous IIV were 1.08 (95% confidence interval, 1.05 to -1.09) times more likely to return. CONCLUSIONS: Withdrawal of the LAIV recommendation was not associated with an overall change in child influenza immunization rates across seasons. Children with a previous (2015-2016) IIV were slightly more likely to return during the 2016-2017 season for influenza immunization than those with a previous LAIV.

Invasive cervical cancer among American Indian women in the Northern Plains, 1994-1998: incidence, mortality, and missed opportunities.

OBJECTIVES: Cervical cancer mortality rates among the American Indian and Alaska Native (AI/AN) population in North and South Dakota were five times the national average (15.6 per 100,000 vs. 3.1 per 100,000, age adjusted) when last evaluated (from 1989 through 1993). Our goals were to update the AI/AN population cervical cancer mortality rates and to present incidence rates for AI/AN women in the region. METHODS: We reviewed charts for women diagnosed with invasive cervical cancer at Indian Health Service (IHS) facilities in North and South Dakota from 1994 through 1998 and collected information about cervical cancer screening and treatment history. Incidence and mortality rates were standardized to the 1970 U.S. population. RESULTS: Twenty-one cases of invasive cervical cancer and eight deaths were identified. Annualized incidence and mortality rates were 11.5 per 100,000 and 4.5 per 100,000. These compare with national all-race/ethnicity rates of 8.5 per 100,000 and 2.7 per 100,000 for incidence and mortality. Fifteen (71%) of 21 cases were diagnosed due to symptoms. CONCLUSIONS: While cervical cancer mortality rates have declined, incidence and mortality rates among AI/AN women remain higher than in the general U.S. population. Increased use of pap tests and careful follow-up of abnormal results should be aggressively promoted among AI/AN women in North and South Dakota.

Collaboration between Oregon's chronic disease programs and Medicaid to decrease smoking among Medicaid-insured Oregonians with asthma.

BACKGROUND: Environmental tobacco smoke is a leading environmental asthma trigger and has been linked to the development of asthma in children and adults. Smoking cessation and reduced exposure to secondhand tobacco smoke are key components of asthma management. We describe a partnership involving two state agencies and 14 health plans; the goal of the partnership was to decrease smoking and exposure to environmental tobacco smoke among Medicaid-insured Oregonians with asthma. CONTEXT: Oregon's asthma rate is higher than that of the national population, and approximately one third of Oregonians with asthma smoke. The Health Promotion and Chronic Disease Prevention Program (HPCDP) in the Oregon Department of Human Services has collaborated with the Office of Medical Assistance Programs (OMAP) to promote preventive care at the population level. METHODS: Two HPCDP programs--the Oregon Asthma Program and the Oregon Tobacco Prevention and Education Program--worked with OMAP to launch the statewide Asthma-Tobacco Integration Project in 2003. A primary focus of the project is the development of partnerships among health plans, health care providers, and large health care organizations to integrate asthma management and smoking control through systems innovations and provider education. OMAP and its participating health plans also decided to focus cessation efforts on its members with chronic diseases. In addition, HPCDP has collaborated with OMAP to distribute educational tools and information about tobacco's impact on asthma morbidity to Oregon's health care providers who serve low-income Oregonians. CONSEQUENCES: The partnership between OMAP and HPCDP program staff members has allowed them to discuss problems, leverage resources, and obtain support for many public health initiatives. In addition, OMAP-HPCDP collaboration on educational workshops and outreach to health care providers has helped convince quality improvement specialists and administrators about the importance of addressing smoking among patients with asthma. The Asthma-Tobacco Integration Project has also led to formative research aimed at increasing community involvement in promoting tobacco-free environments. INTERPRETATION: Collaboration between HPCDP and OMAP has been an important factor in Oregon's successful smoking cessation efforts in general and in recent efforts to address tobacco use among Oregonians with asthma.

Perceived likelihood of developing diabetes among high-risk Oregonians.

INTRODUCTION: Prevention of diabetes in people at highest risk for developing the disease is an important public health opportunity, considering the disease's increasing prevalence, its devastating impact on health and its high economic cost, the availability of efficacious and cost-effective treatments to reduce complications, and recent evidence that it can be delayed or prevented with lifestyle interventions. METHODS: The Oregon Diabetes Prevention and Control Program collected and analyzed responses from a statewide telephone survey conducted in 2003 to determine whether Oregon adults at highest risk for diabetes 1) believed that they were at risk for developing diabetes in the future, 2) had talked with a health care professional about diabetes, and 3) had been tested for the disease. Pearson chi-square tests and logistic regression analyses were conducted to identify independent associations of select characteristics with the study factors of interest. RESULTS: Even among respondents at highest risk for developing diabetes, at most one third reported being concerned about developing diabetes, one fifth reported having discussed their risk with a health professional in the previous year, and less than half reported having been tested for diabetes by a health provider in the previous year. After adjusting for multiple factors, we found that having a family history of diabetes was consistently associated with perceived risk of developing diabetes, discussion about diabetes with a health professional, and diabetes testing. CONCLUSION: Many Oregon adults at high risk for developing diabetes are unconcerned about their risk for developing the disease, and few have discussed their risk of diabetes with a health professional. Findings from this study suggest the need for increased recognition of future diabetes risk by high-risk individuals and health professionals to help translate diabetes prevention into practice.

Nasal carriage of methicillin-resistant Staphylococcus aureus in an American Indian population.

BACKGROUND AND OBJECTIVE: Although reports of methicillin-resistant Staphylococcus aureus (MRSA) infections without healthcare exposure are increasing, population-based data regarding nasal colonization are lacking. We assessed the prevalence of and risk factors for community-associated MRSA nasal carriage in patients of a rural outpatient clinic. DESIGN: A cross-sectional population survey was conducted through random sample and stratification by community of residence. Recent healthcare exposure (ie, hospitalization, dialysis, or healthcare occupation) and other risk factors for MRSA carriage were assessed. Cultures of the nares were performed. Community-associated MRSA was defined as MRSA carriage without healthcare exposure. SETTING: A predominantly American Indian community in Washington. PATIENTS: Those receiving healthcare from an Indian Health Service clinic. RESULTS: Of 1,311 individuals identified for study, 475 (36%) participated. Unsatisfactory culture specimens resulted in exclusion of 6 participants. In all, 128 (27.3%) of 469 participants had S. aureus. Nine (1.9%) of 469 had MRSA carriage; of these, 5 had community-associated MRSA (5 of 469; overall community-associated MRSA carriage rate, 1.1%). MRSA carriage was associated with antimicrobial use in the previous year (risk ratio [RR], 7.2; P = .04) and residence in a household of more than 7 individuals (RR, 4.5; P = .03). Pulsed-field gel electrophoresis indicated that 5 (55%) of 9 MRSA carriage isolates were closely related, including 3 (60%) of 5 that were community associated. CONCLUSIONS: Prevalence of community-associated MRSA colonization was approximately 1% in this rural, American Indian population. Community-associated MRSA colonization was associated with recent antimicrobial use and larger household.

An outbreak of community-onset methicillin-resistant Staphylococcus aureus skin infections in southwestern Alaska.

OBJECTIVE: We investigated a large outbreak of community-onset methicillin-resistant Staphylococcus aureus (MRSA) infections in southwestern Alaska to determine the extent of these infections and whether MRSA isolates were likely community acquired. DESIGN: Retrospective cohort study. SETTING: Rural southwestern Alaska. PATIENTS: All patients with a history of culture-confirmed S. aureus infection from March 1, 1999, through August 10, 2000. RESULTS: More than 80% of culture-confirmed S. aureus infections were methicillin resistant, and 84% of MRSA infections involved skin or soft tissue; invasive disease was rare. Most (77%) of the patients with MRSA skin infections had community-acquired MRSA (no hospitalization, surgery, dialysis, indwelling line or catheter, or admission to a long-term-care facility in the 12 months before infection). Patients with MRSA skin infections were more likely to have received a prescription for an antimicrobial agent in the 180 days before infection than were patients with methicillin-susceptible S. aureus skin infections. CONCLUSIONS: Our findings indicate that the epidemiology of MRSA in rural southwestern Alaska has changed and suggest that the emergence of community-onset MRSA in this region was not related to spread of a hospital organism. Treatment guidelines were developed recommending that beta-lactam antimicrobial agents not be used as a first-line therapy for suspected S. aureus infections.
