Why home environment matters for Recurrent Chest Infections
Damp, mould, cold homes, and inadequate ventilation are causally linked to recurrent respiratory infection. The pathway is multi-factorial: cold-induced ciliary dysfunction reduces clearance, mould-related airway inflammation reduces local defence, indoor airborne pathogens accumulate without ventilation, and crowded / multi-generational households increase person-to-person transmission. The house-as-host concept is well-established in NIHR-funded UK housing research.
UK prevalence: Recurrent chest infections (3+ lower respiratory tract infections per year in adults, or significantly higher rates in children) affect a meaningful proportion of UK primary-care presentations during winter, particularly in older adults and immunocompromised patients.
