Associations between sunshine and influenza or influenza-like illness, a systematic review and meta-analysis.

ABSTRACT: Influenza and influenza-like illness (ILI) impose an immense burden to public health. Exposure to ultraviolet (UV) radiation might impact the spread of influenza. We examined associations between UV radiation and sunshine duration and influenza or ILI. We performed a systematic review and meta-analysis including studies with UV radiation, UV index or sunshine duration as exposure and influenza/ILI as outcome. A random-effects meta-analysis was conducted using the Knapp-Hartung method to calculate the pooled relative risks (RR) of the associations between UV radiation and sunshine duration and influenza. Several sensitivity analyses were performed. 45 studies which met the eligibility criteria were included in the systematic review, of which 16 were included for meta-analysis, covering more
