Virus, allergic sensitisation and cortisol in infant bronchiolitis and risk of early asthma

Acute bronchiolitis during infancy and human rhinovirus (HRV) lower respiratory tract infections increases the risk of asthma in atopic children. We aimed to explore whether specific viruses, allergic sensitisation or cortisol levels during acute bronchiolitis in infancy increase the risk of early asthma, using recurrent wheeze as a proxy.In 294 children with a mean (range) age of 4.2 (0-12) months enrolled during hospitalisation for acute...
