Background: In Malawi approximately, 88.3% people living with HIV are aware of their HIV status. Significant gaps are among men aged 15–34 years; only 72% know their HIV status. To reach men, Jhpiego, in collaboration with the Ministry of Health (MOH), implemented the Men's Mobile Wellness Clinic (MMWC) at workplace settings in Blantyre, Malawi between October 2019 and March 2020. Methods: We conducted a descriptive qualitative study to understand motivators and barriers to MMWC service uptake by employees and employers. Primary data was drawn from in-depth telephone interviews from four study populations: employers who accepted or declined to host the MMWC at their worksite, and employees who accessed or did not access the services. We performed a thematic analysis using Nvivo 12 software to identify patterns and themes across the dataset. Findings: Main reasons given for using the service among male employees were a desire to know their health status, availability of free health services at the workplace, and good quality services offered by MMWC staff, and support from their supervisor. Men who did not access services stated reasons such as work-clinic scheduling conflicts, lack of adequate promotion of the service, and miscommunication on the criteria about who should attend the MMWC. Employers who accepted to host the MMWC stated convenience and employee's rights to know their health status. Those who declined either stated that employees did not want the services or COVID-19 preventive measures by the MOH between October 2019 and March 2020 restricted participation. Conclusion: This study underscores the potential utility of MMWC services including HIV testing among men. The desire to know their health status, availability of free MMWC services at the workplace, good quality services offered by MMWC staff, and the endorsement of MMWC by supervisors were main motivators to access the MMWC services. Sensitizing supervisors and employees about the benefits of the MMWC services, strengthening demand creation, and clarifying eligibility are important to facilitate MMWC uptake among men in Malawi.

Black gay, bisexual, and other men who have sex with men (GBM) are disproportionately affected by HIV and STIs. Safe Spaces 4 Sexual Health (SS4SH), a community-informed, status-neutral HIV/STI testing intervention combines online outreach via geo-social networking apps and social media with mobile van testing. During 2018–2019, we recruited 25 participants for interviews about their perceptions of SS4SH compared to clinic-based testing. Participants were aged 21–65 years (mean 35); 22 (88%) identified as Black/African American; 20 (80%) identified as gay; and 10 (40%) were living with HIV. Interviews were transcribed, coded, and analyzed using a modified thematic constant comparative approach. Five themes emerged; two related to perceptions of online outreach materials (participants were drawn to eye-catching and to-the-point messages and desired more diversity and representation in messages), and three related to preference for the mobile van (participants found SS4SH provided more comfort, more privacy/confidentiality, and increased accessibility and efficiency). GBM is increasingly using geo-social networking apps to meet sexual partners, and tailored online outreach has the potential to reach historically underserved populations. SS4SH is a barrier-reducing strategy that may serve as an entry to a status-neutral approach to services and help reduce stigma and normalize accessing HIV services. [ABSTRACT FROM AUTHOR]

Hispanic/Latino persons are disproportionately impacted by HIV in the US, and HIV diagnoses among Hispanic/Latino men in Georgia have increased over the past decade, particularly in metropolitan Atlanta. In 2022, the Georgia Department of Public Health detected five clusters of rapid HIV transmission centered among Hispanic/Latino gay, bisexual, and other men who have sex with men (HLMSM) in metropolitan Atlanta. We conducted in-depth interviews with 65 service providers and 29 HLMSM to identify barriers and facilitators to HIV service access for HLMSM. Interviews were audio recorded, transcribed, and translated, if needed. Initial data analyses were conducted rapidly in the field to inform public health actions. We then conducted additional analyses including line-by-line coding of the interview transcripts using a thematic analytic approach. We identified four main themes. First, inequity in language access was a predominant barrier. Second, multiple social and structural barriers existed. Third, HLMSM encountered intersectional stigma. Finally, the HLMSM community is characterized by its diversity, and there is not a one-size-fits-all approach to providing appropriate care to this population. The collection of qualitative data during an HIV cluster investigation allowed us to quickly identity barriers experienced by HLMSM when accessing HIV and other medical care, to optimize public health response and action. Well-designed program evaluation and implementation research may help elucidate specific strategies and tools to reduce health disparities, ensure equitable service access for HLMSM, and reduce HIV transmission in this population.

Pre-exposure prophylaxis (PrEP) is highly effective in preventing new HIV infection, but uptake remains challenging among Black and Hispanic/Latino persons. The purpose of this review was to understand how studies have used electronic telecommunication technology to increase awareness, uptake, adherence, and persistence in PrEP care among Black and Hispanic/Latino persons and how it can reduce social and structural barriers that contribute to disparities in HIV infection. Of the 1114 articles identified, 10 studies were eligible. Forty percent (40%) of studies focused on Black or Hispanic/Latino persons and 80% addressed social and structural barriers related to PrEP use such as navigation or access to PrEP. Mobile health designs were more commonly used (50%) compared to telehealth (30%) and e-health (20%) designs. There is a need to increase the development of telecommunications interventions that address the needs of Black and Hispanic/Latino persons often challenged with uptake and adherent use of PrEP.

Knowledge about monkeypox transmission risk in congregate settings is limited. In July 2022, the Chicago Department of Public Health (CDPH) confirmed a case of monkeypox in a person detained in Cook County Jail (CCJ) in Chicago, Illinois. This case was the first identified in a correctional setting in the United States and reported to CDC during the 2022 multinational monkeypox outbreak. CDPH collaborated with CCJ, the Illinois Department of Public Health (IDPH), and CDC to evaluate transmission risk within the facility. Fifty-seven residents were classified as having intermediate-risk exposures to the patient with monkeypox during the 7-day interval between the patient's symptom onset and his isolation. (Intermediate-risk exposure was defined as potentially being within 6 ft of the patient with monkeypox for a total of ≥3 hours cumulatively, without wearing a surgical mask or respirator, or potentially having contact between their own intact skin or clothing and the skin lesions or body fluids from the patient or with materials that were in contact with the patient's skin lesions or body fluids.) No secondary cases were identified among a subset of 62% of these potentially exposed residents who received symptom monitoring, serologic testing, or both. Thirteen residents accepted postexposure prophylaxis (PEP), with higher acceptance among those who were offered counseling individually or in small groups than among those who were offered PEP together in a large group. Monkeypox virus (MPXV) DNA, but no viable virus, was detected on one surface in a dormitory where the patient had been housed with other residents before he was isolated. Although monkeypox transmission might be limited in similar congregate settings in the absence of higher-risk exposures, congregate facilities should maintain recommended infection control practices in response to monkeypox cases, including placing the person with monkeypox in medical isolation and promptly and thoroughly cleaning and disinfecting spaces where the person has spent time. In addition, officials should provide information to residents and staff members about monkeypox symptoms and transmission modes, facilitate confidential monkeypox risk and symptom disclosure and prompt medical evaluation for symptoms that are reported, and provide PEP counseling in a private setting.

In 2017 and 2019, five outbreaks of infections from multiple strains of Salmonella linked to the consumption of whole, fresh Maradol papayas were reported in the United States, resulting in 325 ill persons. Traceback, laboratory, and epidemiologic evidence indicated papayas as the likely vehicle for each of these outbreaks and identified the source of papayas. State and U.S. Food and Drug Administration (FDA) laboratories recovered Salmonella from papaya samples from various points of distribution, including at import entry, and conducted serotyping, pulsed-field gel electrophoresis, and phylogenetic analyses of whole genome sequencing data. Federal and state partners led traceback investigations to determine the source of papayas. Four different suppliers of papayas were linked by traceback and laboratory results to five separate outbreaks of Salmonella infections associated with papayas. In 2017, multiple states tested papaya samples collected at retail, and Maryland and Virginia investigators recovered strains of Salmonella associated with one outbreak. FDA collected 183 papaya samples in 2017, and 11 samples yielded 62 isolates of Salmonella. Eleven serotypes of Salmonella were recovered from FDA papaya samples, and nine serotypes were closely related genetically by pulsed-field gel electrophoresis and whole genome sequencing to clinical isolates of four outbreaks, including the outbreak associated with positive state sample results. Four farms in Mexico were identified, and their names were released to the general public, retailers, and foreign authorities. In 2019, FDA collected 119 papaya samples, three of which yielded Salmonella; none yielded the 2019 outbreak strain. Investigators determined that papayas of interest had been sourced from a single farm in Campeche, Mexico, through traceback. This information was used to protect public health through public guidance, recalls, and import alerts and helped FDA collaborate with Mexican regulatory partners to enhance the food safety requirements for papayas imported from Mexico.

The article presents an investigation by the U.S. Department of Agriculture (USDA), and the Food and Drug Administration (FDA) towards a multistate outbreak of 356 Salmonella Reading infections from different states and the District of Columbia (DC) which linked to turkey. It identifies Salmonella Reading infections with an indistinguishable pulsed-field gel electrophoresis (PFGE) pattern and highlights the steps that should take to reduce Salmonella contamination in their products.

On 10 August 2016, the Maricopa County Department of Public Health identified culture-confirmed Salmonella enterica serotype Javiana isolates from two persons who reported eating at a seafood restaurant; seven additional cases were reported by 15 August. We investigated to identify a source and prevent further illness. We interviewed persons with laboratory-reported Salmonella Javiana infection. Pulsed-field gel electrophoresis (PFGE) and whole genome sequencing of isolates were performed. A case was defined as diarrheal illness in a person during July to September 2016; confirmed cases had Salmonella Javiana isolate yielding outbreak-related PFGE patterns; probable cases had diarrheal illness and an epidemiologic link to a confirmed case. Case finding was performed (passive surveillance and identification of ill meal companions). A case-control study assessed risk factors for Salmonella Javiana infection among restaurant diners; control subjects were chosen among meal companions. No restaurant workers reported illness. Foods were reportedly cooked according to the Food Code. Food and environmental samples were collected and cultured; Salmonella Javiana with an indistinguishable PFGE pattern was isolated from portioned repackaged raw shrimp, halibut, and a freezer door handle. We identified 50 Salmonella Javiana cases (40 confirmed and 10 probable); illness onset range was from 22 July to 17 September 2016. Isolates from 40 patients had highly related PFGE patterns. Thirty-three (73%) of 45 patients interviewed reported eating at the restaurant. Among 21 case patients and 31 control subjects, unfried cooked shrimp was associated with illness (odds ratio, 6.7; 95% confidence interval, 1.8 to 24.9; P ¼ 0.004). Among restaurant diners, laboratory and case-control evidence indicated shrimp as the possible outbreak source; poor thermal inactivation of Salmonella on shrimp is theorized as a possible cause. Cross-contamination might have prolonged this outbreak; however, the source was not identified and highlights limitations that can arise during these types of investigations. [ABSTRACT FROM AUTHOR]

Foodborne salmonellosis causes an estimated 1 million illnesses and 400 deaths annually in the United States (1). Salmonella Anatum is one of the top 20 Salmonella serotypes in the United States. During 2013-2015 there were approximately 300-350 annual illnesses reported to PulseNet, the national molecular subtyping network for foodborne disease surveillance. In June 2016, PulseNet identified a cluster of 16 Salmonella Anatum infections with an indistinguishable pulsed-field gel electrophoresis (PFGE) pattern from four states.* In April 2016, the same PFGE pattern had been uploaded to PulseNet from an isolate obtained from an Anaheim pepper, a mild to medium hot pepper. Hot peppers include many pepper varieties, such as Anaheim, jalapeño, poblano, and serrano, which can vary in heat level from mild to very hot depending on the variety and preparation. This rare PFGE pattern had been seen only 24 times previously in the PulseNet database, compared with common PFGE patterns for this serotype which have been seen in the database hundreds of times. Local and state health departments, CDC, and the Food and Drug Administration (FDA) investigated to determine the cause of the outbreak. Thirty-two patients in nine states were identified with illness onsets from May 6-July 9, 2016. Whole-genome sequencing (WGS) was performed to characterize clinical isolates and the Anaheim pepper isolate further. The combined evidence indicated that fresh hot peppers were the likely source of infection; however, a single pepper type or source farm was not identified. This outbreak highlights challenges in reconciling epidemiologic and WGS data, and the difficulties of identifying ingredient-level exposures through epidemiologic investigations alone.
