Coronavirus disease (COVID-19) Community Testing Team in Scotland: A 14-day review, 6 to 20 February 2020.

In response to the outbreak of COVID-19, we set up a team to carry out sampling in the community. This enabled individuals to remain in self-isolation in their own homes and to prevent healthcare settings and services from being overwhelmed by admissions for sampling of suspected cases. There is evidence that this is a cost effective, safe and necessary service to complement COVID-19 testing in hospitals.

SARS-CoV-2 vaccine uptake and risks of severe COVID-19 disease among people prescribed opioid agonist therapy in Scotland.

BACKGROUND: There is limited evidence quantifying the risk of severe COVID-19 disease among people with opioid dependence. We examined vaccine uptake and severe disease (admission to critical care or death with COVID-19) among individuals prescribed opioid agonist therapy (OAT). METHOD: A case-control design was used to examine vaccine uptake in those prescribed OAT compared with the general population, and the association between severe disease and OAT. In both analyses, 10 controls from the general population were matched (to each OAT recipient and COVID-19 case, respectively) according to socio-demographic factors. Conditional logistic regression was used to estimate rate ratios (RR) for severe disease. RESULTS: Vaccine uptake was markedly lower in the OAT cohort (dose 1: 67%, dose 2: 53% and dose 3: 31%) compared with matched controls (76%, 72% and 57%, respectively). Those prescribed OAT within the last 5 years, compared with those not prescribed, had increased risk of severe COVID-19 (RR 3.38, 95% CI 2.75 to 4.15), particularly in the fourth wave (RR 6.58, 95% CI 4.20 to 10.32); adjustment for comorbidity and vaccine status attenuated this risk (adjusted RR (aRR) 2.43, 95% CI 1.95 to 3.02; wave 4 aRR 3.78, 95% CI 2.30 to 6.20). Increased risk was also observed for those prescribed OAT previously (>3 months ago) compared with recently (aRR 1.74, 95% CI 1.11 to 2.71). CONCLUSIONS: The widening gap in vaccine coverage for those prescribed OAT, compared with the general population, is likely to have exacerbated the risk of severe COVID-19 in this population over the pandemic. However, continued OAT use may have provided protection from severe COVID-19 among those with opioid dependence.

Major incidents in rural areas: managing a pandemic A/H1N1/2009 cluster.

CONTEXT: Pandemic Influenza (A/H1N1/2009) caused worldwide concern because of its potential to spread rapidly in human populations. In Scotland, Government policy had been to seek to contain the spread of the virus for as long as possible in order to allow time for service preparations, and for vaccine development and supply. ISSUE: The first major Scottish outbreak of pandemic A/H1N1/2009 was in the rural area of Cowal and Bute. After two initial cases were identified, contact tracing found a cluster of cases associated with a football supporters' bus. Within 3 weeks, 130 cases had been identified in the area. Rapid provision of treatment doses of anti-viral medication to cases and prophylactic treatment of asymptomatic close contacts, advice on self-isolation and, where required, interruption of transmission by temporary school closure, were successful in containing the outbreak. LESSONS LEARNED: Pre-existing Major Incident and Pandemic Flu plans were used and adapted to the particular circumstances of the outbreak and the area. Supporting operational decision-making as close to the cases as possible allowed for speed and flexibility of response. Contact tracing and tracking of cases and results was performed by specialist public health staff who were geographically removed from the cases. This was possible because of effective use of existing telephone conferencing facilities, clarity of roles, and frequent communication among staff working on all areas of the response. Basing the work on established plans, staff experience of rural areas and rural service provision was successful.

Evolution and effects of COVID-19 outbreaks in care homes: a population analysis in 189 care homes in one geographical region of the UK.

BACKGROUND: COVID-19 has affected care home residents internationally, but detailed information on outbreaks is scarce. We aimed to describe the evolution of outbreaks of COVID-19 in all care homes in one large health region in Scotland. METHODS: We did a population analysis of testing, cases, and deaths in care homes in the National Health Service (NHS) Lothian health region of the UK. We obtained data for COVID-19 testing (PCR testing of nasopharyngeal swabs for severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) and deaths (COVID-19-related and non-COVID-19-related), and we analysed data by several variables including type of care home, number of beds, and locality. Outcome measures were timing of outbreaks, number of confirmed cases of COVID-19 in care home residents, care home characteristics associated with the presence of an outbreak, and deaths of residents in both care homes and hospitals. We calculated excess deaths (both COVID-19-related and non-COVID-19-related), which we defined as the sum of deaths over and above the historical average in the same period over the past 5 years. FINDINGS: Between March 10 and Aug 2, 2020, residents at 189 care homes (5843 beds) were tested for COVID-19 when symptomatic. A COVID-19 outbreak was confirmed at 69 (37%) care homes, of which 66 (96%) were care homes for older people. The size of care homes for older people was strongly associated with a COVID-19 outbreak (odds ratio per 20-bed increase 3·35, 95% CI 1·99-5·63). 907 confirmed cases of SARS-CoV-2 infection were recorded during the study period, and 432 COVID-19-related deaths. 229 (25%) COVID-19-related cases and 99 (24%) COVID-related deaths occurred in five (3%) of 189 care homes, and 441 (49%) cases and 207 (50%) deaths were in 13 (7%) care homes. 411 (95%) COVID-19-related deaths occurred in the 69 care homes with a confirmed COVID-19 outbreak, 19 (4%) deaths were in hospital, and two (<1%) were in one of the 120 care homes without a confirmed COVID-19 outbreak. At the 69 care homes with a confirmed COVID-19 outbreak, 74 excess non-COVID-19-related deaths were reported, whereas ten non-COVID-19-related excess deaths were observed in the 120 care homes without a confirmed COVID-19 outbreak. 32 fewer non-COVID-19-related deaths than expected were reported among care home residents in hospital. INTERPRETATION: The effect of COVID-19 on care homes has been substantial but concentrated in care homes with known outbreaks. A key implication from our findings is that, if community incidence of COVID-19 increases again, many care home residents will be susceptible. Shielding care home residents from potential sources of SARS-CoV-2 infection, and ensuring rapid action to minimise outbreak size if infection is introduced, will be important for any second wave. FUNDING: None.

Prevention and control of sexually transmissible infections among hotel-based female sex workers in Dhaka, Bangladesh.

BACKGROUND: Hotel-based sex workers in Bangladesh have high rates of sexually transmissible infections (STIs), high client turnover and low condom use. Two monthly clinic-based strategies were compared: periodic presumptive treatment (PPT) and enhanced syndromic management (ESM) - one round of presumptive treatment followed by treatment based on assessment and laboratory tests. METHODS: A randomised controlled trial compared PPT and ESM by prevalence and incidence, behaviour, retention, cost and STI incidence and prevalence. Demographic, behavioural and clinical data were collected from women at two clinics in Dhaka. All women received presumptive treatment and were randomised to receive PPT or ESM at nine monthly visits. RESULTS: In total, 549 women (median age: <20 years) were enrolled. At baseline, the prevalence of chlamydia (Chlamydia trachomatis) and gonorrhoea (Neisseria gonorrhoeae) was 41% (ESM: 41%; PPT: 42%). After 9 months, chlamydia and gonorrhoea decreased to 7% overall, (ESM: 7.4%; PPT: 6.8%). At each visit, 98% of women receiving ESM met the therapy criteria and were treated. Retention was low (50%). Total costs were 50% lower per visit for each woman for PPT (ESM: $11.62 v. PPT: $5.80). The number of sex work sessions was reduced from 3.3 to 2.5 (P<0.001), but income did not change. Coercion was reduced but condom use at last sex did not change significantly. CONCLUSIONS: Monthly PPT and ESM were effective approaches for STI control. PPT offered a feasible, low-cost alternative to ESM. Educational aspects led to a reduction in coercion and fewer sessions. Implementation studies are needed to improve condom use and retention.
