Cross-national study reveals prevalence and impact of smell and taste disorders on quality of life in the UK and USA, suggesting urgent need for support.
KEY POINTS: Anosmia/hyposmia affected 14.8%-19.6% of participants in the UK and the USA in the post-pandemic era. Since symptom onset, 37.1%-48.8% of affected participants reported no improvement, while 15.3%-17.6% reported worsening symptoms. Anosmia/hyposmia remains strongly associated with reduced quality of life across both countries. Among respondents reporting anosmia or hyposmia, a high proportion (88.8%-93.5%) also experienced concurrent parosmia.
