Indoor moulds in asthmatic patients homes

A study was conducted in 29 households with asthmatic patients in order to analyse the indoor mould concentration; an important contamination was found in both the air and the dust. Although it is known that the outdoor mould concentration in the air decreases during winter, we found that the indoor one did not vary throughout the year. Moreover, the indoor mould concentration increased during the winter in recently built houses, probably because of the poor ventilation.
