RESUMEN
Among 9048 people infected with SARS-CoV-2 between January and May 2021 in Maryland, in regression-adjusted analysis, SARS-CoV-2 viruses carrying the spike protein mutation E484K were disproportionately prevalent among persons infected after full vaccination against COVID-19 compared with infected persons who were not fully vaccinated (aOR, 1.96; 95% CI: 1.36-2.83).

Data on monkeypox in children and adolescents aged <18 years are limited (1,2). During May 17September 24, 2022, a total of 25,038 monkeypox cases were reported in the United States, primarily among adult gay, bisexual, and other men who have sex with men (3). During this period, CDC and U.S. jurisdictional health departments identified Monkeypox virus (MPXV) infections in 83 persons aged <18 years, accounting for 0.3% of reported cases. Among 28 children aged 012 years with monkeypox, 64% were boys, and most had direct skin-to-skin contact with an adult with monkeypox who was caring for the child in a household setting. Among 55 adolescents aged 1317 years, most were male (89%), and male-to-male sexual contact was the most common presumed exposure route (66%). Most children and adolescents with monkeypox were non-Hispanic Black or African American (Black) (47%) or Hispanic or Latino (Hispanic) (35%). Most (89%) were not hospitalized, none received intensive care unit (ICU)level care, and none died. Monkeypox in children and adolescents remains rare in the United States. Ensuring equitable access to monkeypox vaccination, testing, and treatment is a critical public health priority. Vaccination for adolescents with risk factors and provision of prevention information for persons with monkeypox caring for children might prevent additional infections.

Nearly all cases of melioidosis in the continental United States are related to international travel to areas to which Burkholderia pseudomallei, the bacterium that causes melioidosis, is endemic. We report the diagnosis and clinical course of melioidosis in a patient from the United States who had no international travel history and the public health investigation to determine the source of exposure. We tested environmental samples collected from the patient's home for B. pseudomallei by PCR and culture. Whole-genome sequencing was conducted on PCR-positive environmental samples, and results were compared with sequences from the patient's clinical specimen. Three PCR-positive environmental samples, all collected from a freshwater home aquarium that had contained imported tropical fish, were a genetic match to the clinical isolate from the patient. This finding suggests a novel route of exposure and a potential for importation of B. pseudomallei, a select agent, into the United States from disease-endemic areas.

In late January 2021, a clinical laboratory notified the Maryland Department of Health (MDH) that the SARS-CoV-2 variant of concern B.1.351 had been identified in a specimen collected from a Maryland resident with COVID-19 (1). The SARS-CoV-2 B.1.351 lineage was first identified in South Africa (2) and might be neutralized less effectively by antibodies produced after vaccination or natural infection with other strains (3-6). To limit SARS-CoV-2 chains of transmission associated with this index patient, MDH used contact tracing to identify the source of infection and any linked infections among other persons. The investigation identified two linked clusters of SARS-CoV-2 infection that included 17 patients. Three additional specimens from these clusters were sequenced; all three had the B.1.351 variant and all sequences were closely related to the sequence from the index patient's specimen. Among the 17 patients identified, none reported recent international travel or contact with international travelers. Two patients, including the index patient, had received the first of a 2-dose COVID-19 vaccination series in the 2 weeks before their likely exposure; one additional patient had a confirmed SARS-CoV-2 infection 5 months before exposure. Two patients were hospitalized with COVID-19, and one died. These first identified linked clusters of B.1.351 infections in the United States with no apparent link to international travel highlight the importance of expanding the scope and volume of genetic surveillance programs to identify variants, completing contact investigations for SARS-CoV-2 infections, and using universal prevention strategies, including vaccination, masking, and physical distancing, to control the spread of variants of concern.

COVID-19 vaccine breakthrough infection surveillance helps monitor trends in disease incidence and severe outcomes in fully vaccinated persons, including the impact of the highly transmissible B.1.617.2 (Delta) variant of SARS-CoV-2, the virus that causes COVID-19. Reported COVID-19 cases, hospitalizations, and deaths occurring among persons aged ≥18 years during April 4-July 17, 2021, were analyzed by vaccination status across 13 U.S. jurisdictions that routinely linked case surveillance and immunization registry data. Averaged weekly, age-standardized incidence rate ratios (IRRs) for cases among persons who were not fully vaccinated compared with those among fully vaccinated persons decreased from 11.1 (95% confidence interval [CI] = 7.8-15.8) to 4.6 (95% CI = 2.5-8.5) between two periods when prevalence of the Delta variant was lower (<50% of sequenced isolates; April 4-June 19) and higher (≥50%; June 20-July 17), and IRRs for hospitalizations and deaths decreased between the same two periods, from 13.3 (95% CI = 11.3-15.6) to 10.4 (95% CI = 8.1-13.3) and from 16.6 (95% CI = 13.5-20.4) to 11.3 (95% CI = 9.1-13.9). Findings were consistent with a potential decline in vaccine protection against confirmed SARS-CoV-2 infection and continued strong protection against COVID-19-associated hospitalization and death. Getting vaccinated protects against severe illness from COVID-19, including the Delta variant, and monitoring COVID-19 incidence by vaccination status might provide early signals of changes in vaccine-related protection that can be confirmed through well-controlled vaccine effectiveness (VE) studies.

To evaluate progress toward prevention of enteric illnesses, the Foodborne Diseases Active Surveillance Network (FoodNet) of CDC's Emerging Infections Program monitors the incidence of laboratory-diagnosed infections caused by eight pathogens transmitted commonly through food at 10 U.S. sites.* This report summarizes preliminary 2019 data and describes changes in incidence compared with that during 2016-2018. The incidence of enteric infections caused by these eight pathogens reported by FoodNet sites in 2019 continued to increase or remained unchanged, indicating progress in controlling major foodborne pathogens in the United States has stalled. Campylobacter and Salmonella caused the largest proportion of illnesses; trends in incidence varied by Salmonella serotype. Widespread adoption of whole genome sequencing (WGS) of bacteria has improved the ability to identify outbreaks, emerging strains, and sources of pathogens. To maximize the potential of WGS to link illnesses to particular sources, testing of isolates by clinical and public health laboratories is needed. Reductions in Salmonella serotype Typhimurium suggest that targeted interventions (e.g., vaccinating chickens and other food animals) might decrease human infections. Reducing contamination during food production, processing, and preparation will require more widespread implementation of known prevention measures and of new strategies that target particular pathogens and serotypes.

On September 17, 2017, the Maryland Department of Agriculture (MDA) was notified by fair and 4-H officials of ill swine at agricultural fair A, held September 14-17. That day, investigation of the 107 swine at fair A revealed five swine with fever and signs of upper respiratory tract illness. All five respiratory specimens collected from these swine tested positive for influenza A virus at the MDA Animal Health Laboratory, and influenza A(H3N2) virus was confirmed in all specimens by the U.S. Department of Agriculture National Veterinary Services Laboratory (NVSL). On September 18, MDA was notified by fair and 4-H officials that swine exhibitors were also ill. MDA alerted the Maryland Department of Health (MDH). A joint investigation with MDH and the local health department was started and later broadened to Maryland agricultural fairs B (September 13-17) and C (September 15-23). In total, 76 persons underwent testing for variant influenza, and influenza A(H3N2) variant (A(H3N2)v) virus infection was identified in 40 patients with exposure to swine at these fairs (Figure), including 30 (75%) who had more than one characteristic putting them at high risk for serious influenza complications; 24 (60%) of these were children aged <5 years. Twenty-six (65%) patients reported direct contact with swine (i.e., touching swine or swine enclosure), but 14 (35%) reported only indirect contact (e.g., walking through a swine barn). Two children required hospitalization; all patients recovered. This outbreak highlights the risk, particularly among children, for contracting variant influenza virus at agricultural fairs after direct or indirect swine contact. Publicizing CDC's recommendation that persons at high risk for serious influenza complications avoid pigs and swine barns might help prevent future variant influenza outbreaks among vulnerable groups (1).

OBJECTIVES: Early in the COVID-19 pandemic, several outbreaks were linked with facilities employing essential workers, such as long-term care facilities and meat and poultry processing facilities. However, timely national data on which workplace settings were experiencing COVID-19 outbreaks were unavailable through routine surveillance systems. We estimated the number of US workplace outbreaks of COVID-19 and identified the types of workplace settings in which they occurred during August-October 2021. METHODS: The Centers for Disease Control and Prevention collected data from health departments on workplace COVID-19 outbreaks from August through October 2021: the number of workplace outbreaks, by workplace setting, and the total number of cases among workers linked to these outbreaks. Health departments also reported the number of workplaces they assisted for outbreak response, COVID-19 testing, vaccine distribution, or consultation on mitigation strategies. RESULTS: Twenty-three health departments reported a total of 12 660 workplace COVID-19 outbreaks. Among the 12 470 workplace types that were documented, 35.9% (n = 4474) of outbreaks occurred in health care settings, 33.4% (n = 4170) in educational settings, and 30.7% (n = 3826) in other work settings, including non-food manufacturing, correctional facilities, social services, retail trade, and food and beverage stores. Eleven health departments that reported 3859 workplace outbreaks provided information about workplace assistance: 3090 (80.1%) instances of assistance involved consultation on COVID-19 mitigation strategies, 1912 (49.5%) involved outbreak response, 436 (11.3%) involved COVID-19 testing, and 185 (4.8%) involved COVID-19 vaccine distribution. CONCLUSIONS: These findings underscore the continued impact of COVID-19 among workers, the potential for work-related transmission, and the need to apply layered prevention strategies recommended by public health officials.

BACKGROUND: There has been limited evaluation of tools for teaching social determinants of health (SDOH). OBJECTIVE: We evaluated a field trip as a tool for teaching SDOH to incoming medical interns. METHODS: Incoming interns from The George Washington University participated in a bus field trip of Washington, DC, guided by community partners. The field trip introduced trainees to local neighborhoods. Pre- and postactivity surveys developed by the authors were analyzed using a Wilcoxon signed rank test. Reflection responses were recorded and counted for recurrent themes. RESULTS: Incoming interns participated in 2015 (85 of 90, 94%) and in 2016 (96 of 116, 83%). Postactivity, basic knowledge of DC geographic health disparities increased, and a greater percentage of interns reported being at least somewhat comfortable understanding the neighborhoods from which their patients come (2015: 58% versus 89%, P < .0001; 2016: 65% versus 88%, P < .0001); identifying challenges to health care that affect low-income patients (2015: 74% versus 90%, P < .0023); describing community resources (2015: 29% versus 67%, P < .0001; 2016: 29% versus 50%, P < .0001); and referring patients to local community resources (2015: 25% versus 64%, P < .0001; 2016: 36% versus 52%, P < .0001). Interns reported that this experience improved their understanding of patients' background and local resources, and that they would change the way they practice. CONCLUSIONS: A bus field trip guided by community partners is a feasible way to increase residents' perception of their understanding of local disparities and comfort in addressing SDOH.

BACKGROUND: The IOM recommends public health training for all physicians. Data characterizing such training of internal medicine (IM) residents are lacking. PURPOSE: To describe the current state of public health education at IM residency programs, characterize programs offering public health education, and quantify interest in expanding training opportunities. METHODS: IM residency program directors from the 380 Accreditation Council for Graduate Medical Education-accredited residency programs in the U.S were invited to participate in a cross-sectional survey. Responses were received from 127 programs (33%). Data were collected July-December 2012 and analyzed in January 2013. Participants were queried on domestic public health training offered, perceived resident interest in and satisfaction with this training, and interest in expanding training. RESULTS: Eighty-four respondents (66%) provide some form of public health training, but structure and content vary widely. In many programs offering public health training, few residents (<10%) receive it. Although 93 programs (73%) integrate public health into core curricula, only three topics were common to a majority of these programs. Sixty-six respondents (52%) offer clinical training at community-based health centers. Most residency program directors (90%) are very or somewhat interested in expanding their public health training. CONCLUSIONS: This study characterizes the structures and content of public health training across IM residency programs. The wide range highlights the diverse definition of "public health training" used by IM residency program directors and lack of universal public health competencies required for IM physicians. Opportunities exist for collaboration among residency programs and between IM and public health educators to share best practices.

SUMMARY Chronic pain represents a staggering public health burden. Despite research and technologic advances in pain management, chronic pain is grossly undertreated in the USA. Many pain patients are dissatisfied with their treatment regimens, and disparities exist in pain treatment for minorities and for socioeconomically disadvantaged and elderly patients. Many doctors feel inadequately trained to treat chronic pain. Therapeutic opioid use for chronic pain is a particularly challenging issue for both physicians and patients. Strategies for addressing chronic pain from a public health perspective include increased education of physicians and the public, improved integration of pain management across disciplines, and improved systems for monitoring prescription opioids.
RESUMEN
This study aimed to characterize the experience of having a treatment supporter among HIV-infected South African patients enrolled in a randomized controlled trial that compared the efficacy of patient-nominated treatment supporters administering partial directly observed antiretroviral therapy (DOT-ART) versus self-administered ART (Self-ART). Results of the parent study showed no virologic or sustained immunologic differences between groups, but revealed a significant survival benefit among the DOT-ART group. One hypothesis is that this survival benefit may be explained by differences in the training and involvement of the treatment supporters between groups. In the current study, results from a semi-structured exit interview of 172 participants indicate that most participants in both arms maintained a positive, satisfying relationship with a single supporter, typically family member or friend. Most patients (82.6%) perceived supporters as helpful with medication adherence, with no significant difference between groups (p=0.752). Additionally, supporters provided emotional, instrumental, and material support. DOT-ART patients were more likely than Self-ART patients to report that their supporter helped to decrease drug or alcohol use (p=0.03). Patients identified supporter trustworthiness, availability, good communication and reciprocity of support as factors beneficial to a successful relationship. These results suggest: (1) Patient-nominated peers are feasible candidates for ART supporters in this resource-constrained setting; (2) In addition to assistance with medications, treatment supporters have the capacity to promote healthy behaviors and provide other types of support, which may contribute to improved outcomes, particularly with enhanced training; (3) Trustworthiness, availability, good communication, and reciprocity are key factors in a successful patient-supporter relationship.

Chronic pain is one of the most common reasons for patients to seek medical care. Chronic pain results in substantial economic losses and remains one of the most costly conditions in modern western society. In 1991, costs were estimated to be approximately $65 billion annually, comparable to the cost of treating diabetes. Persistent chronic pain and the use of advanced interventional and pharmacological treatments often leads to complex social and psychological maladaptations, health care overutilization, as well as many other substantial direct and indirect costs. Thus, the proper treatment of chronic pain involves intense multidisciplinary management, including pharmacological, behavioral, and psychological interventions. Few studies have assessed the total economic cost of chronic pain. However, many of the chronic pain treatments do not alleviate pain symptoms for most patients and lead to unsuccessful application of resources. The economic consequences of inadequately treated chronic pain translates into lost work days, overutilization of health care resources (excess hospitalizations, and surgical procedures and inappropriate medications) and other out-of-pocket patient expenses. Increasing emphasis on diagnosis and treatment of chronic pain places more importance on the need for efficient and coordinated management of patient with chronic pain. The management of chronic pain is remarkably complex and resource intensive. Therefore, a clear need exists for intensive pharmacoeconomic investigations, specifically evaluating costs related to chronic pain and the associated treatment modalities. Additionally, evaluation of the costs related to chronic pain would measure the economic burden of chronic pain, including an estimate of the amount that could potentially be saved if chronic pain patients are optimally managed.
