Indoor air quality in hospitals is a concern due to presence of
airborne microorganisms that may cause nosocomial infections (Beggs CB,
2003). Few published reports have studied the seasonal fluctuations in
microbial loads over time in hospital environment (Augustowska and
Dutkiewicz, 2006). While studies in developing countries have documented
presence of nosocomially significant bacteria and fungi in indoor air
of healthcare facilities (Sudharsanam et al., 2008; Ekhaise et al.,
2008), these studies were not performed over extended time periods to
ascertain the influence of seasonal changes on airborne microbial loads.
Nosocomial infection also known as hospital acquired infection is an
infection acquired in a hospital environment, which was not present in
the patient at the time of admission (Beggs, 2003). Hospitals are
potentially conducive for antimicrobial resistant and virulent pathogens
to proliferate. Large numbers of microorganisms are found in indoor air
and it is of great importance to carry out regular survey as a
yardstick of determining standard of cleanliness in hospitals (Williams
et al., 1956). The sources of hospital airborne infection or
contamination could be traced to a variety of factors. These include the
patient’s own normal flora, linens, bed sheets, staff clothes, visitors
and the materials such as flowers. Activity of patients (sneezing,
coughing, talking, yawning) and the number of patients per room may
likewise be sources of hospital infection (Jaffal et al., 1997a; Ekhaise
et al., 2008; 2010). It has also been reported that microbiological
pollutants such as animal droplets, plants, building materials and air
conditioning system have played significant role in the spread of
airborne microflora. Materials such as files kept close to bedside in
surgical wards have been implicated as a viable source (Burge et al.,
2000).
1.1 AIMS AND OBJECTIVES
This study was aimed at
investigating the microbial load and the quality of indoor air of four
difference wards/units and outside the hospital gate of Faith Mediplex
Centre, Benin City.
To isolate and characterize the airborne
micro-flora from hospital environment and to ascertain their
contribution to infection rate in the hospital.

ABSRACT - [ Total Page(s): 1 ]This study was aimed at investigating the microbial load and the quality of indoor air Faith Mediplex Centre, Benin City, to ascertain their contribution to infection rate in the hospital. Air samples were assessed for three (3) months (June-August, 2015) using the settled plate methods. The study sites were divided into five (5) units; male medical ward, female medical ward, treatment room, operating theatre and outside the hospital gate. The result obtained reveal the isolation of six (6) bact ... Continue reading---
