Indoor airborne bacteria and fungi at different background area in nurseries and day care centres environments

Respiratory symptoms among children cases increased dramatically was believe due to poor indoor air quality. Nursery and day care centre (DCC) appear to be the site of exposure and transmission of airborne microorganism between children. This study aims to assess the relation between the colony fo...
