Seroprevalence and Genotype Diversity of Hepatitis C Virus in the Caribbean-A Review.

Hepatitis C (HCV) continues to present a global public health challenge, with no vaccine available for prevention. Despite the availability of direct-acting antivirals (DAAs) to cure HCV, it remains prevalent in many regions including the Caribbean. As efforts are made to eliminate HCV from the region, existing barriers, such as the high cost of DAAs and lack of an established database of HCV cases within the Caribbean, must be addressed.

Knowledge, Practice and Attitudes to the Management of Sepsis in Jamaica.

Introduction: Sepsis is a life-threatening dysfunction resulting from the dysregulated host response to infection. The mortality of sepsis in Jamaica remains high amid the proven efficacy of the Surviving Sepsis Guidelines implementation in some countries.

Aim Of Study: To evaluate the inter-relationship of healthcare workers' attitude towards, knowledge of and practice of sepsis management in Jamaica.

Evaluation of OneStep Dengue NS1 RapiDip™ InstaTest and OneStep Dengue Fever IgG/IgM RapiCard™ InstaTest during the course of a dengue type 1 epidemic.

We determined the diagnostic performance of the OneStep NS1 and the OneStep IgG/IgM RDT kits against a panel of samples which comprised of 174 dengue positive and 165 dengue negative sera characterized by three reference enzyme-linked immunosorbent assays (ELISAs). The diagnostic sensitivities of the OneStep kits for the detection of individual biomarkers of NS1, IgM and IgG were 90% (95% CI: 82.1-94.

The epidemiology of invasive pneumococcal disease in older adults in the post-PCV era. Has there been a herd effect?

The 7 and 13-valent pneumococcal conjugate vaccines (PCVs) have reduced the incidence of invasive pneumococcal disease (IPD) in children in many countries. The objective of this work was to assess the impact of PCVs and potential herd-protection in older adults in Ireland. IPD notification and typing data from adults ⩾65 years of age from July 2007 to June 2016 was assessed using national surveillance data.

Dysregulated TGF-β Production Underlies the Age-Related Vulnerability to Chikungunya Virus.

Chikungunya virus (CHIKV) is a re-emerging global pathogen with pandemic potential, which causes fever, rash and debilitating arthralgia. Older adults over 65 years are particularly susceptible to severe and chronic CHIKV disease (CHIKVD), accounting for >90% of all CHIKV-related deaths. There are currently no approved vaccines or antiviral treatments available to limit chronic CHIKVD.
