Assessment
Indoor
air quality is a term which refers to the air quality within and around
buildings and structures especially as it relates to the health and
comfort of its occupants. Indoor air can be polluted by various
compounds such as carbon monoxide, volatile organic compounds (VOCs),
particulate matter and microbial contaminants (moulds, bacteria,
viruses) and any action that introduces harmful contaminants into the
air within the building. The concern for quality indoor air is necessary
especially in institutionalized settings that accommodate a large
number of people such as hospitals, nursing homes, prisons, schools,
family because contaminated air can cause both mild and severely
irritating health conditions (Tambeker et al., 2007). The quality of air
in hospitals in relation to microbial contamination at a given time
period is determined by the quality of air entering into the building,
the number of occupants in the building, their physical activities and
resultant aerosol generation, human traffic and the efficiency of
ventilation (Adebolu and Vhirterhre, 2002).Microbiological Assessment
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.Microbiological Assessment
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).Microbiological
Assessment
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.Microbiological Assessment

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---
