Human Melioidosis Caused by Novel Transmission of Burkholderia pseudomallei from Freshwater Home Aquarium, United States1.

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.

Influenza A(H3N2) Variant Virus Outbreak at Three Fairs - Maryland, 2017.

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).

Public health training in internal medicine residency programs: a national survey.

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.

Patient-nominated, community-based HIV treatment supporters: patient perspectives, feasibility, challenges, and factors for success in HIV-infected South African adults.

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.
