Catheter-associated bloodstream infections and urinary tract infections are frequently encountered health care-associated infections. We aimed to reduce inappropriate use of catheters to reduce health care-associated infections. ⋯ Netherlands Organisation for Health Research and Development.

Randomized Controlled Trial Multicenter Study
Safety and immunogenicity of a parenteral trivalent P2-VP8 subunit rotavirus vaccine: a multisite, randomised, double-blind, placebo-controlled trial.
A monovalent, parenteral, subunit rotavirus vaccine was well tolerated and immunogenic in adults in the USA and in toddlers and infants in South Africa, but elicited poor responses against heterotypic rotavirus strains. We aimed to evaluate safety and immunogenicity of a trivalent vaccine formulation (P2-VP8-P[4],[6],[8]). ⋯ Bill & Melinda Gates Foundation.

Observational Study
Using observational data to quantify bias of traveller-derived COVID-19 prevalence estimates in Wuhan, China.
The incidence of coronavirus disease 2019 (COVID-19) in Wuhan, China, has been estimated using imported case counts of international travellers, generally under the assumptions that all cases of the disease in travellers have been ascertained and that infection prevalence in travellers and residents is the same. However, findings indicate variation among locations in the capacity for detection of imported cases. Singapore has had very strong epidemiological surveillance and contact tracing capacity during previous infectious disease outbreaks and has consistently shown high sensitivity of case-detection during the COVID-19 outbreak. ⋯ US National Institute of General Medical Sciences, and Fellowship Foundation Ramon Areces.

Elucidation of the chain of disease transmission and identification of the source of coronavirus disease 2019 (COVID-19) infections are crucial for effective disease containment. We describe an epidemiological investigation that, with use of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serological assays, established links between three clusters of COVID-19. ⋯ National Research Foundation (Singapore), National Natural Science Foundation (China), and National Medical Research Council (Singapore).
