TL;DR: In this paper, a randomized controlled trial was conducted to determine the relationship between vitamin D status and upper respiratory tract infection (URTI) of physically active men and women across seasons, and investigate the effects on URTI and mucosal immunity of achieving vitamin D sufficiency (25(OH)D ≥50 nmol·L-1) by a unique comparison of safe, simulated-sunlight or oral D3 supplementation in winter.

TL;DR: A higher lifetime number of sexual partners is associated with a number of sociodemographic and behavioural factors that may help health practitioners to identify individuals who are at greatest risk of sexually transmitted infection and their associated health complications across the life course.
