  Seven live-in houses situated in two different types of housing conditions in Port Harcourt, Rivers State of Nigeria and their occupants were used in identifying the common mould related health problems associated with people living in houses with moisture problem. Five of the houses were identified with having moisture problem as a result of constant flooding from rainfall, poor or total lack of drainages and leakages from roofs, sinks, pipes and walls while the other two houses were basically moisture problem free. Air samples from all the rooms of the study sites were collected, processed and the presence of moulds confirmed in them. Eighty human specimens made up of hair, skin scrapes, nails and sputum from the occupants were processed with 20% KOH in a wet mount preparation and cultured on sabouraud dextrose agar incorporated with chloramphenicol. The percentage occurrence of mould related health problems encountered in this study were Tinea cruris (10%), Tinea capitis (20%), Tinea corporis (20%), Tinea unguium (15%), Tinea pedis (10%), Tinea barbae (5%) and persistent sneezing, headache and cough (20%). Tinea capitis, corporis and persistent sneezing headache and cough which accounted for 20% each were found to be the most common mould related health problems associated with people living in houses with moisture problem.

  n order to determine the moulds that were prevalent in houses with moisture problem, 288 sampling sessions were carried out in 12 living houses in Port Harcourt area of Rivers State. The houses were identified to have moisture problem as a result of constant flooding and leakages. Air samples were collected once a month for 24 months as well as temperature and relative humidity readings. Flooding and leakage incidence were also recorded. Samples were processed using potassium hydroxide for direct microscopy and cultured on sabouraud dextrose agar medium containing chloramphenicol. Microscopic examination of culture was done using lactophenol cotton blue mounting technique. All study sites yielded mould isolates. Sixteen different species of mould were isolated from the sampling sites Trichophyton rubrum and Mucor sp. were the most prevalent moulds with a total occurrence of 288 (13.8%) followed by Microsporum audouinii with 201 (9.6%), Trichophyton mentagrophytes 176 (8.4%), Penicillium sp. 175 (8.4%), Aspergillus flavus 165 (7.9%), Aspergillus fumigatus 148 (7.1%) and Microsporum ferrugineum 109 (5.2%). The lowest percentage occurrence was from Trichophyton schoenleinii 26 (1.2%). Buildings with consistent moisture problem and relative humidity above 60% will always provide a conducive and fertile ground for the growth of moulds.
