Oshikata C, Watanabe M, Ishida M, et al. - Previously, an elevated prevalence of asthma was documented in adults who lived in temporary housing following the 2011 Great East Japan Earthquake, researchers herein sought to determine alterations in asthma prevalence as well as mite-specific immunoglobulin E (IgE) titers in temporary housing residents during 2014–2019. Across all age-groups, asthma prevalence exceeded 20% throughout the study span. A positive correlation with the duration of temporary housing was demonstrated by Dermatophagoides pteronyssinus-specific IgE concentration whereas it was identified to be inversely correlated with the time elapsed since moving out of temporary housing. Findings revealed the presence of mite allergen sensitization in both asthmatic and nonasthmatic temporary housing residents following the 2011 Japan earthquake and tsunami; occurrence of asthma was witnessed even after individuals moved out of temporary housing.
