Seasonal variability in indoor relative humidity and temperature are associated with fungal concentration in house dust in New York City

Autumn and springtime peaks in asthma exacerbations have been attributed to environmental exposures, including fungal allergens and respiratory viruses. We previously found that total fungal concentration in New York City homes was significantly greater in spring compared to other seasons. We hypothesize that indoor relative humidity (RH) and temperature underlie these seasonal trends. Further, we predict indoor RH and temperature will be significantly increased in springtime and correlate with total fungal concentration in house dust.
