Clade I mpox virus genomic diversity in the Democratic Republic of the Congo, 2018-2024: Predominance of zoonotic transmission.

Recent reports raise concerns on the changing epidemiology of mpox in the Democratic Republic of the Congo (DRC). High-quality genomes were generated for 337 patients from 14/26 provinces to document whether the increase in number of cases is due to zoonotic spillover events or viral evolution, with enrichment of APOBEC3 mutations linked to human adaptation. Our study highlights two patterns of transmission contributing to the source of human cases. All new sequences from the eastern South Kivu province (n = 17; 4.8%) corresponded to the recently described clade Ib, associated with sexual contact and sustained human-to-human transmission. By contrast, all other genomes are clade Ia, which exhibits high genetic diversity with low numbers of APOBEC3 mutations compared with clade Ib, suggesting multiple zoonotic introductions. The presence of multiple clade I variants in urban areas highlights the need for coordinated international response efforts and more studies on the transmission and the reservoir of mpox.

Mpox Vaccine Acceptance, Democratic Republic of the Congo.

We report general acceptance (61.0%) of an mpox vaccine in the Democratic Republic of the Congo among 5,226 survey respondents. Healthcare workers and respondents in historic mpox-endemic regions had higher acceptance rates. These data highlight the need for increased community engagement and sensitization before widespread deployment of mpox vaccines.

Presumed Transmission of 2 Distinct Monkeypox Virus Variants from Central African Republic to Democratic Republic of the Congo.

We linked 4 mpox cases in South Ubangi, Democratic Republic of the Congo, to transboundary transmission from Central African Republic. Viral genome sequencing demonstrated that the monkeypox virus sequences belonged to distinct clusters of subclade Ia. This finding demonstrates the borderless nature of mpox and highlights the need for vigilant regional surveillance.

Co-Circulating Monkeypox and Swinepox Viruses, Democratic Republic of the Congo, 2022.

In September 2022, deaths of pigs manifesting pox-like lesions caused by swinepox virus were reported in Tshuapa Province, Democratic Republic of the Congo. Two human mpox cases were found concurrently in the surrounding community. Specific diagnostics and robust sequencing are needed to characterize multiple poxviruses and prevent potential poxvirus transmission.

Co-circulation of monkeypox virus subclades Ia and Ib in Kinshasa Province, Democratic Republic of the Congo, July to August 2024.

Between January and August 2024, mpox cases have been reported in nearly all provinces of the Democratic Republic of the Congo (DRC). Monkeypox virus genome sequences were obtained from 11 mpox cases' samples, collected in July-August 2024 in several health zones of Kinshasa. Characterisation of the sequences showed subclades Ia and Ib co-circulating in the Limete health zone, while phylogenetic analyses suggested multiple introductions of the two subclades in Kinshasa. This illustrates the growing complexity of Clade I mpox outbreaks in DRC.

Political engagement: a key pillar in revitalisation of polio and routine immunisation programmes in the Democratic Republic of the Congo.

Immunisation is a high priority for improving health outcomes. Yet, in many low-income and middle-income countries, achieving coverage targets independently is hindered by lack of domestic resources and reliance on partners' support. Both the 2001 Abuja Declaration and 2016 Addis Declaration were key political commitments to improving immunisation coverage; however, many signatories have yet to meet international targets. Despite signing the Global Vaccine Action Plan and Addis Declaration, the Democratic Republic of the Congo (DRC) was unable to fully disburse its portion of allocated funds to cover vaccines without support from Gavi, the Vaccine Alliance and the World Bank between 2017 and 2019. Additionally, during the same time, vaccine coverage outcomes indicated negative trends, with over 750 000 children considered 'zero-dose' in 2018. In 2019, a primary focus of the then newly elected President's agenda was universal healthcare. In collaboration with development partners and stakeholders, the first Presidential Forum was held as a public commitment to increasing childhood immunisation and ensuring the country remains polio-free. This article seeks to highlight the key outcomes of the Forum such as the signing of the Kinshasa Declaration, which formally set targets and specified national, provincial and community-level commitments to vaccination and polio eradication. As of 2023, three Forums have been conducted to reiterate political commitment to routine immunisation in the DRC. This type of high-level commitment could serve as a template for other countries struggling to have high engagement as targets for polio eradication and strengthened routine immunisation are set for 2025-2030.

First imported Cases of MPXV Clade Ib in Goma, Democratic Republic of the Congo: Implications for Global Surveillance and Transmission Dynamics.

The ongoing national mpox outbreak in the Democratic Republic of the Congo has resulted in more >30,000 suspected cases in the country from January 2023 to August 2024. While these historic case totals have been driven by primarily by zoonosis, the emergence of Clade Ib monkeypox virus (MPXV), which is connected to more sustained human-to-human transmission, has been associated with increasing public health impacts in eastern DRC. First identified in South Kivu province, Clade Ib MPXV has been identified in multiple non-endemic East African countries for the first time. In DRC, there have been concerns over broader Clade Ib expansion in the country that could further complicate containment and mitigation responses. Here, we report the first introductions of Clade Ib into North Kivu province, including within internal displacement camps, with suspected close contact transmission that includes non-intimate contacts and children. These findings demonstrate that mpox case investigations and community messaging campaigns should include considerations for non-sexual contact-mediated transmission of Clade Ib that includes children <15 years.

A Successful National and Multipartner Approach to Increase Immunization Coverage: The Democratic Republic of Congo Mashako Plan 2018-2020.

BACKGROUND: The immunization system in the Democratic Republic of the Congo faces many challenges, including persistent large-scale outbreaks of polio, measles, and yellow fever; a large number of unvaccinated children for all antigens; minimal and delayed funding; and poor use of immunization data at all levels. In response, the Expanded Programme on Immunization within the Ministry of Health (MOH) collaborated with global partners to develop a revitalization strategy for the routine immunization (RI) system called the Mashako Plan. MASHAKO PLAN DESIGN AND DEVELOPMENT: The Mashako Plan aimed to increase full immunization coverage in children aged 12-23 months by 15 percentage points overall in 9 of 26 provinces within 18 months of implementation. In 2018, we conducted a diagnostic review and identified gaps in coordination, service delivery, vaccine availability, real-time monitoring, and evaluation as key areas for intervention to improve the RI system. Five interventions were then implemented in the 9 identified provinces. DISCUSSION: According to the 2020 vaccine coverage survey, full immunization coverage increased to 56.4%, and Penta3/DTP3 increased to 71.1% across the Mashako Plan provinces; the initial objective of the plan was reached and additional improvements in key service delivery indicators had been achieved. Increases in immunization sessions held per month, national stock of pentavalent vaccine, and supervision visits conducted demonstrate that simple, measurable changes at all levels can quickly improve immunization systems. Despite short-term improvements in all indicators tracked, challenges remain in vaccine availability, regular funding of immunization activities, systematic provision of immunization services, and ensuring long-term sustainability. CONCLUSIONS: Strong commitment of MOH staff combined with partner involvement enabled the improvement of the entire system. A simple set of interventions and indicators focused the energy of managers on discrete actions to improve outcomes. Further exploration of the results is necessary to determine the long-term impact and generate all-level engagement for sustainable success in all provinces.

Strengthening immunization programs through innovative sub-national public-private partnerships in selected provinces in the Democratic Republic of the Congo.

BACKGROUND: Low immunization coverage rates in the Democratic Republic of Congo (DRC) have been reflective of challenges with vaccine access, support and delivery in the country. Motivated by measles and vaccine-derived polio virus (VDPV) outbreaks in 2016-17 and low vaccination rates, the provinces of Haut Lomami and Tanganyika were identified as pilot locations for an innovative approach focused on establishing a consortium of partners supporting local government. This approach was formalized through Memorandums of Understanding (MoUs) between the Bill and Melinda Gates Foundation and Provincial governments in 2018. A third province, Lualaba, established an MoU in 2021. MOU IMPLEMENTATION: These MoUs were 5-year partnerships designed to aid provinces in meeting four key objectives: 80 % immunization coverage, management/elimination of polio/cVDPV outbreaks, improvement of vaccine accessibility, and transfer of immunization service management to provincial leadership. OUTCOMES: During the MoU period, Haut-Lomami saw an increase in full immunization coverage, from 35.7 % (MICS 2018) to 88.9 % (VCS 2021-22), the highest in country. A sharp drop in percentage of zero-dose children was observed in the 3 provinces, confirming improved access to immunization services. Tanganyika saw initial improvement in full immunization coverage, followed by a drop in the VCS 2021-22 due to COVID-19 and healthcare worker strikes. Coverage improved in Tanganyika in the 2023 VCS. The 3 provinces increased their financial contributions to routine immunization and are now the top contributing provinces. While no cVDPV cases were recorded in 2020 and 2021, cVDPV1 and cVDPV2 outbreaks are afflicting the 3 provinces since 2022. CONCLUSIONS: Ultimately, the provincial MoUs were successful in bolstering provincial autonomy and capacity building with the biggest success being a drop in zero-dose children. While not all objectives have been met, the MoU approach served as an innovative program for key aspects of strengthening routine immunization in the DRC.

Jail-based treatment for opioid use disorder in the era of bail reform: a qualitative study of barriers and facilitators to implementation of a state-wide medication treatment initiative.

BACKGROUND: Until recently, few carceral facilities offered medications for opioid use disorder (MOUD). Although more facilities are adopting MOUD, much remains to be learned about addressing implementation challenges related to expansion of MOUD in carceral settings and linkage to care upon re-entry. This is particularly important in jails, where individuals cycle rapidly in and out of these facilities, especially in jurisdictions beginning to implement bail reform laws (i.e., laws that remove the requirement to pay bail for most individuals). Increasing access to MOUD in these settings is a key unexplored challenge. METHODS: In this qualitative study, we interviewed staff from county jails across New Jersey, a state that has implemented state-wide efforts to increase capacity for MOUD treatment in jails. We analyzed themes related to current practices used to engage individuals in MOUD while in jail and upon re-entry; major challenges to delivering MOUD and re-entry services, particularly under bail reform conditions; and innovative strategies to facilitate delivery of these services. RESULTS: Jail staff from 11 New Jersey county jails participated in a baseline survey and an in-depth qualitative interview from January-September 2020. Responses revealed that practices for delivering MOUD varied substantially across jails. Primary challenges included jails' limited resources and highly regulated operations, the chaotic nature of short jail stays, and concerns regarding limited MOUD and resources in the community. Still, jail staff identified multiple facilitators and creative solutions for delivering MOUD in the face of these obstacles, including opportunities brought on by the COVID-19 pandemic. CONCLUSIONS: Despite challenges to the delivery of MOUD, states can make concerted and sustained efforts to support opioid addiction treatment in jails. Increased use of evidence-based clinical guidelines, greater investment in resources, and increased partnerships with health and social service providers can greatly improve reach of treatment and save lives.

Helminth-induced reprogramming of the stem cell compartment inhibits type 2 immunity.

Enteric helminths form intimate physical connections with the intestinal epithelium, yet their ability to directly alter epithelial stem cell fate has not been resolved. Here we demonstrate that infection of mice with the parasite Heligmosomoides polygyrus bakeri (Hpb) reprograms the intestinal epithelium into a fetal-like state marked by the emergence of Clusterin-expressing revival stem cells (revSCs). Organoid-based studies using parasite-derived excretory-secretory products reveal that Hpb-mediated revSC generation occurs independently of host-derived immune signals and inhibits type 2 cytokine-driven differentiation of secretory epithelial lineages that promote their expulsion. Reciprocally, type 2 cytokine signals limit revSC differentiation and, consequently, Hpb fitness, indicating that helminths compete with their host for control of the intestinal stem cell compartment to promote continuation of their life cycle.

Structural and organizational factors shaping access to medication treatment for opioid use disorder in community supervision.

BACKGROUND: Four million individuals in the U.S. criminal-legal system are supervised in the community under probation or parole. Sentences to community supervision often mandate participation in substance use treatment. Yet evidence-based treatment with medication (i.e., methadone, buprenorphine, or naltrexone) is rarely offered to people under community supervision with opioid use disorder (OUD). This qualitative study explores the structural and organizational factors shaping OUD medication treatment use in community supervision. METHODS: We conducted in-depth interviews with 31 community supervision professionals. Thematic analysis characterized interview participants' perceptions of the key factors shaping use of OUD medications in community supervision. FINDINGS: Findings indicate that authorities making decisions about OUD treatment include community supervision agencies, treatment providers, judges and courts, and jails and prisons. Agencies with more rehabilitative cultural orientations are more forgiving of relapse and supportive of OUD medications. Punishment/enforcement orientations align with an emphasis on surveillance and drug testing, which can inhibit medication treatment and interrupt continuity of care. Community supervision agencies generally reported deference to the recommendations of substance use treatment providers regarding the details of treatment, including the use of medication. Given that most treatment providers do not offer OUD medication, community supervision agencies must develop a sophisticated understanding of the various services offered by local treatment providers to tailor referrals accordingly, a responsibility for which they may be inadequately trained. CONCLUSIONS: Efforts to improve engagement with medication treatment in U.S. community supervision settings could have a significant impact on reincarceration, morbidity, and mortality among individuals with OUD under supervision.

Methadone and buprenorphine treatment in United States jails and prisons: lessons from early adopters.

AIMS: To identify implementation barriers and facilitators to the adoption and implementation of programs that provide opioid agonist treatments (OAT) with methadone and buprenorphine to treat opioid use disorder in jails and prisons in the United States. DESIGN: Qualitative analysis: semi-structured interviews were conducted and thematic analyses of transcripts and notes were performed using a hybrid inductive/deductive coding approach. SETTING: Jails and prisons in the United States. PARTICIPANTS: From August 2019 to January 2020, we conducted 20 key informant interviews with 35 individuals representing 19 carceral systems that both initiate and maintain OAT. MEASUREMENTS: Interviews covered four domains: (1) program adoption; (2) policy influence on implementation; (3) program structure; and (4) program outcomes. FINDINGS: Stigma among staff, particularly medical staff, challenged program adoption, but reduced over time as staff were exposed to the program. Regulations on OAT dispensation, such as licensing requirements and prescribing limits, were key challenges to program implementation and shaped program structure. Dispensing medication required significant staff, time and space. Facilities were further challenged to overcome stigma and concerns about diversion, as OAT medication is often treated as contraband in carceral settings. Some systems deviated from evidence-based treatment by limiting OAT dosage to low levels, requiring counseling for participation and requiring detoxification before medication initiation. Despite these challenges, early adopters felt strongly that other jails and prisons in the United States should provide OAT and that legislation and litigation may soon force OAT expansion in these carceral settings. CONCLUSIONS: Despite identifying regulatory and logistical challenges, early adopters of opioid agonist treatment (OAT) programs in US jails and prisons demonstrate that OAT programs can successfully be implemented in carceral settings with tailoring to the specific context.

Early Effects of COVID-19 on Programs Providing Medications for Opioid Use Disorder in Jails and Prisons.

OBJECTIVES: To describe how the novel coronavirus (COVID-19) pandemic has affected opioid agonist treatment (OAT) programs in jails and prisons. METHODS: In May 2020, we conducted an online survey of 19 carceral systems that provided methadone and/or buprenorphine treatment for incarcerated populations before COVID-19. Eleven survey items examined challenges and changes to these programs as a result of the pandemic. Sixteen of 19 programs (84%) responded to the survey. RESULTS: Ten out of 16 systems reported downsizing their OAT programs. Seven of 16 systems made changes to medication dispensation processes. Half of systems report challenges implementing physical distancing (n = 8), and/or obtaining personal protective equipment (n = 8). In 13 out of 16 systems some OAT program participants were released early due to COVID-19 infection risk. CONCLUSIONS: Jails and prisons with existing OAT programs have curtailed their operations in the context of the COVID-19 pandemic. Given the robust evidence base around OAT for treating opioid use disorder and averting overdose deaths, guidance is needed on maintaining and ramping up medication access as carceral facilities grapple with implementing COVID-19 mitigation.
