Roles of Ambient Temperature and PM_2.5 on Childhood Acute Bronchitis and Bronchiolitis from Viral Infection.

ABSTRACT: Studies have associated the human respiratory syncytial virus which causes seasonal childhood acute bronchitis and bronchiolitis (CABs) with climate change and air pollution. We investigated this association using the insurance claims data of 3,965,560 children aged ≤ 12 years from Taiwan from 2006-2016. The monthly average incident CABs increased with increasing PM_2.5 levels and exhibited an inverse association with temperature. The incidence was 1.6-fold greater in January than in July (13.7/100 versus 8.81/100), declined during winter breaks (February) and summer breaks (June-August). The highest incidence was 698 cases/day at <20 °C with PM_2.5 > 37.0 μg/m³, with an adjusted relative risk (aRR) of 1.01 (95% confidence interval [CI] = 0.97-1.04) com
