mental health associated with personal hygiene.

Health Effects

• Gastro-intestinal illnesses and rare skin infections

are both related to poor personal hygiene and poor sanitation.

• Illnesses resulting from gastro-intestinal infection

can range from mild stomach upsets through to death from diarrheal and gastro-intestinal disease, and severe dysentery, and gastro- enteritis.

• Between 2,000 and 20,000 cases of dysentery are

documented each year and in excess of 80,000 cases of viral gastro-enteritis.

Health Effects

• Dysentery and rotavirus infections are

frequent causes of diarrhea carried by the fecal-oral route.

• Even if the illness is contracted somewhere
• ther than the residence up to 50% of family

members may become infected if the hygiene levels are poor.

Potential for Harm

• Although not a direct cause of physical illness the

following list can be a cause of stress and depression

– odors associated with poor hygiene – the visual appearance of facilities which are difficult to clean or have stained surfaces – damaged decoration and furnishings resulting from splashing or leaking appliances or drainage

• This is particularly the case where the occupant is

renting and where facilities are shared.

• As well as causing anxiety and depression, it can also

cause tension between people sharing facilities.

2015 5

Potential for Harm

• The highest risk groups are the very young (0-

4), the elderly and the immunocompromised.

• Those in houses in multiple occupation with

shared personal hygiene and sanitary facilities are at increased risk, as are low socio- economic groups.

Relevant Matters Affecting Likelihood and Harm Outcome

• Personal hygiene

– Lack of sufficient and/or appropriately sited baths or showers and wash hand basins for the number of

• ccupants or potential occupants.

– Inadequate supplies of hot and cold water to each bath, shower, and wash hand. – The lack of a kitchen sink for each household with separate supplies of cold and hot water.

• Sanitation facilities

– None or an obsolete means for the sanitary collection and removal of human excreta from the dwelling. – Inappropriate or inconvenient location as well as an insufficient number of sanitary closets (bathrooms) for the number of occupants. – Disrepair to bathrooms, inadequate supply of water to the toilet as well as an defective mechanism to the toilet.

Relevant Matters Affecting Likelihood and Harm Outcome – Missing or non-impervious seat and/or lid to a bathroom. – Ventilation to bathroom, inadequate lighting, missing

• r defective door to the bathroom.

– Unhygienic compartment- defective design, construction and/or maintenance of the surfaces to the walls and floor of the compartment resulting in them not being capable of being kept clean and hygienic. – Lack of a wash basin in the room, compartment or immediately adjacent room.

2012 10 2015 10

Relevant Matters Affecting Likelihood and Harm Outcome

• Drainage

– The lack of an adequately sized soil or waste pipe connected to a water-using facility able to carry foul

• r waste water safely to the drainage system.

– Defects to a soil or waste pipe serving a water using facility. – The lack or disrepair of a trap and water seal. – Inadequate ventilation to a soil or waste pipe.

2012 11 2015 11
