Invasive Group A Streptococcus Outbreaks Associated with Home Healthcare, England, 2018-2019.

Healthcare-associated invasive group A Streptococcus (iGAS) outbreaks are common worldwide, but only England has reported outbreaks associated with home healthcare (HHC). We describe 10 outbreaks during 2018-2019 in England. A total of 96 iGAS cases (range 2-39 per outbreak) and 28 deaths (case-fatality rate 29%) occurred. Outbreak duration ranged from 3-517 days; median time between sequential cases was 20.5 days (range 1-225 days). Outbreak identification was difficult, but emm typing and whole-genome sequencing improved detection. Network analyses indicated multiple potential transmission routes. Screening of 366 HHC workers from 9 outbreaks identified group A Streptococcus carriage in just 1 worker. Outbreak control required multiple interventions, including improved infection control, equipment decontamination, and antimicrobial prophylaxis for staff. Transmission routes and effective interventions are not yet clear, and iGAS outbreaks likely are underrecognized. To improve patient safety and reduce deaths, public health agencies should be aware of HHC-associated iGAS.

Evaluation of National Event-Based Surveillance, Nigeria, 2016-2018.

Nigeria Centres for Disease Control and Prevention established an event-based surveillance (EBS) system in 2016 to supplement traditional surveillance structures. The EBS system is comprised of an internet-based data mining tool and a call center. To evaluate the EBS system for usefulness, simplicity, acceptability, timeliness, and data quality, we performed a descriptive analysis of signals received during September 2017-June 2018. We used questionnaires, semistructured interviews, and direct observation to collect information from EBS staff. Amongst 43,631 raw signals detected, 138 (0.3%) were escalated; 63 (46%) of those were verified as events, including 25 Lassa fever outbreaks and 13 cholera outbreaks. Interviewees provided multiple examples of earlier outbreak detections but suggested notifications and logging could be improved to ensure action. EBS proved effective in detecting outbreaks, but we noted clear opportunities for efficiency gains. We recommend improving signal logging, standardizing processes, and revising outputs to ensure appropriate public health action.

The experiences of socially vulnerable groups in England during the COVID-19 pandemic: A rapid health needs assessment.

OBJECTIVES: This rapid health needs assessment was undertaken to urgently identify the needs of socially vulnerable groups arising during the first wave of cases of the COVID-19 pandemic in England. The objective was to develop recommendations for policy makers and stakeholders to mitigate adverse impacts on socially vulnerable groups throughout the COVID-19 response and recovery period. STUDY DESIGN: Rapid health needs assessment. METHODS: The needs assessment employed qualitative methods to systematically collect data about the knowledge and views of key informants through semi-structured interviews and focus groups. Participants were either topic experts providing services to socially vulnerable groups who routinely face barriers to healthcare access or experts by experience. Participants included people experiencing homelessness, sex workers, people from Gypsy, Roma and Traveller communities and people facing challenges due to their immigration status. Data was collected over a week period in April/May 2020 and followed by thematic analysis to examine interview transcripts. RESULTS: Forty-two participants were included in the study, half of whom were experts by experience. Challenges with accessing and following COVID-19 information and government guidance were described as affecting all groups, due to exclusion from digital technology, translated resources, tailored support and adequate housing. Altered delivery of healthcare services, such as the closure of outreach and drop-in services, remote consultations, and online patient registration, were noted by interviewees as worsening existing barriers to accessing healthcare. Being charged for NHS care remained a key fear for migrants. All groups' access to income, education and social support were reported as being impacted by service closures and job losses, putting them at higher risk of destitution. Isolation, loneliness and deteriorating mental health were frequently reported. CONCLUSIONS: This assessment has highlighted the disproportionate impact of the COVID-19 pandemic on socially vulnerable groups and demonstrated a plethora of unmet needs. As the effects of COVID-19 continue, it is imperative that the needs of these groups are urgently and explicitly addressed and prioritised. This is essential to promote engagement with test and trace services, enable isolation adherence, and achieve high vaccine uptake in socially vulnerable populations.

Maternal health after Ebola: unmet needs and barriers to healthcare in rural Sierra Leone.

Sierra Leone has the world's highest estimated maternal mortality. Following the 2014-16 Ebola outbreak, we described health outcomes and health-seeking behaviour amongst pregnant women to inform health policy. In October 2016-January 2017, we conducted a sequential mixed-methods study in urban and rural areas of Tonkolili District comprising: household survey targeting women who had given birth since onset of the Ebola outbreak; structured interviews at rural sites investigating maternal deaths and reporting; and in-depth interviews (IDIs) targeting mothers, community leaders and health workers. We selected 30 clusters in each area: by random GPS points (urban) and by random village selection stratified by population size (rural). We collected data on health-seeking behaviours, barriers to healthcare, childbirth and outcomes using structured questionnaires. IDIs exploring topics identified through the survey were conducted with a purposive sample and analysed thematically. We surveyed 608 women and conducted 29 structured and 72 IDIs. Barriers, including costs of healthcare and physical inaccessibility of healthcare facilities, delayed or prevented 90% [95% confidence interval (CI): 80-95] (rural) vs 59% (95% CI: 48-68) (urban) pregnant women from receiving healthcare. Despite a general preference for biomedical care, 48% of rural and 31% of urban women gave birth outside of a health facility; of those, just 4% and 34%, respectively received skilled assistance. Women expressed mistrust of healthcare workers (HCWs) primarily due to payment demanded for 'free' healthcare. HCWs described lack of pay and poor conditions precluding provision of quality care. Twenty percent of women reported labour complications. Twenty-eight percent of villages had materials to record maternal deaths. Pregnant women faced important barriers to care, particularly in rural areas, leading to high preventable mortality and morbidity. Women wanted to access healthcare, but services available were often costly, unreachable and poor quality. We recommend urgent interventions, including health promotion, free healthcare access and strengthening rural services to address barriers to maternal healthcare.

Low prevalence of transmitted antiretroviral drug resistance in a large UK HIV-1 cohort.

OBJECTIVES: To describe current practice in testing for transmitted antiretroviral drug resistance (TDR) and the prevalence of TDR in a large UK HIV-1 cohort. METHODS: The study includes a retrospective analysis of newly diagnosed HIV-1-infected patients presenting to eight HIV clinics in the north of England between March 2005 and March 2007. Resistance mutations were defined by IAS-USA. Predicted phenotypes were calculated by the Stanford University database. RESULTS: Five hundred and fifty-eight patients were studied, of whom 394 (70.6%) had heterosexually acquired HIV and 377 (67.6%) were infected outside the UK. TDR testing was performed in 406 patients (72.8%). Thirteen of 392 viral resistance profiles (3.3%) showed genotypic TDR. There was no significant association between TDR and any demographic or risk factor or baseline CD4 count. In particular, rates of TDR were similar in white British (6/147, 4.1%) and black African (7/224, 3.1%) patients. The numbers of patients with TDR to individual drug classes were: nucleoside reverse transcriptase inhibitors, 2 (0.5%); non-nucleoside reverse transcriptase inhibitors, 7 (1.8%); and protease inhibitors, 4 (1.0%). No patients had multi-class resistance detected. Eleven patients (2.8%) were predicted to have significant phenotypic resistance to at least one drug. CONCLUSIONS: In a large unselected UK cohort, with high coverage of TDR testing, the prevalence of TDR was low and is in accordance with recent data, showing a decrease in the prevalence of TDR in the UK. Differences in population mix did not appear to explain this low rate.

Infection control in a developing world.

The global HIV and tuberculosis (TB) epidemics have placed enormous burdens upon already overstretched healthcare workers and poorly resourced healthcare facilities in sub-Saharan Africa. The rapid emergence of multi-drug resistant TB, and its association with hospital-based outbreaks, have highlighted the role that healthcare facilities inadvertently may play in maintaining TB transmission, and the vital importance of attaining good TB infection control. James Elston, a specialist physician in infectious diseases and general internal medicine, who recently returned from a second stint in Swaziland, says many of the region's healthcare facilities are outdated, poorly ventilated, and were not designed for their current purpose. Here he describes how U.K.-based architects and healthcare engineers responded to an urgent call for assistance and, via close collaboration, and using novel design software, empowered healthcare workers to dramatically and rapidly improve their TB inpatient facilities, and protect the health of patients and staff.
