Risk factors for SARS-CoV-2 seroprevalence following the first pandemic wave in UK healthcare workers in a large NHS Foundation Trust.

We aimed to measure SARS-CoV-2 seroprevalence in a cohort of healthcare workers (HCWs) during the first UK wave of the COVID-19 pandemic, explore risk factors associated with infection, and investigate the impact of antibody titres on assay sensitivity.  HCWs at Sheffield Teaching Hospitals NHS Foundation Trust were prospectively enrolled and sampled at two time points. We developed an in-house ELISA for testing participant serum for SARS-CoV-2 IgG and IgA reactivity against Spike and Nucleoprotein.

Risk factors for SARS-CoV-2 seroprevalence following the first pandemic wave in UK healthcare workers in a large NHS Foundation Trust.

Background: We aimed to measure SARS-CoV-2 seroprevalence in a cohort of healthcare workers (HCWs) during the first UK wave of the COVID-19 pandemic, explore risk factors associated with infection, and investigate the impact of antibody titres on assay sensitivity.

Methods: HCWs at Sheffield Teaching Hospitals NHS Foundation Trust (STH) were prospectively enrolled and sampled at two time points. SARS-CoV-2 antibodies were tested using an in-house assay for IgG and IgA reactivity against Spike and Nucleoprotein (sensitivity 99·47%, specificity 99·56%).

Hepatitis B: report of prevalence and access to healthcare among Chinese residents in Sheffield UK.

Unlabelled: Overall prevalence of hepatitis B (HBV) in the UK is low. However, among migrants from endemic areas, prevalence has been shown to be high. Furthermore, timely diagnosis and/or referral are required prevent serious health consequences through early institution of treatment.

Management of herpesvirus infections.

Management of human herpesviruses remains a considerable clinical challenge, in part due to their ability to cause both lytic and latent disease. Infection with the Herpesviridae results in lifelong infection, which can reactivate at any time. Control of herpesviruses is by the innate and adaptive immune systems.

Clinical features of viral meningitis in adults: significant differences in cerebrospinal fluid findings among herpes simplex virus, varicella zoster virus, and enterovirus infections.

Background: In this retrospective study, our objective was to review the epidemiology of viral meningitis and to compare clinical features associated with enterovirus, herpes simplex virus (HSV), and varicella zoster virus (VZV) infections in immunocompetent adults.

Methods: Data on cerebrospinal fluid (CSF) samples submitted to the Trust Virology Laboratory (Sheffield, UK) from April 2004 through April 2007 were reviewed. Notes on immunocompetent adults who were polymerase chain reaction (PCR) positive for enterovirus, HSV type 2, or VZV and who had presented to local clinical departments were scrutinized (4 patients were positive for HSV type 1 and did not meet the inclusion criteria).

BD ProbeTec ET assay for the diagnosis of gonorrhoea in a high-risk population: a protocol for replacing traditional microscopy and culture techniques.

Objectives: To evaluate the Neisseria gonorrhoeae Becton Dickinson (BD) ProbeTec strand displacement assay (SDA) on female endocervical swab and male first void urine against culture for Neisseria gonorrhoeae on female endocervical and urethral swab for the diagnosis of N gonorrhoeae infection in genitourinary medicine (GUM) attendees. To determine an algorithm for implementation of N gonorrhoeae infection screening by SDA in these patients taking account of the desirability of having a N gonorrhoeae isolate in people with N gonorrhoeae infection.

Methods: Initially, 1582 patients attending the GUM clinic were tested for N gonorrhoeae infection by SDA and routine microscopy, and culture.

Screening for genital Chlamydia trachomatis in teenagers attending a family planning youth clinic: a prevalence study using a strand displacement assay on urine samples.

Background: Chlamydia trachomatis is the most common bacterial sexually transmitted infection. Rates are highest in the 16-24-year-old age group. Untreated it can be a significant cause of morbidity.
