Mould: The Health Risk Growing on Your Wall
Sylvester Ojenagbon Walk into almost any home after a heavy rain, and you will encounter it somewhere. It could be a dark patch behind the wardrobe, a grey bloom along the bathroom ceiling, or a musty smell that never quite clears. Mould is so ordinary that most people stop noticing it, and that is precisely […]
Mould, a seemingly innocuous issue, poses a significant health risk to homeowners. Often dismissed as a mere cosmetic concern, it can escalate into a dangerous health hazard when conditions such as moisture, warmth, and organic matter are present. Mould spreads by releasing spores, which are ubiquitous in the air and harmless in small quantities.
However, when conditions are conducive to growth, spore counts and volatile compounds can increase sharply, leading to a range of health issues. Common symptoms include coughing, wheezing, a blocked nose, itchy eyes, and skin rashes. For those with asthma, mould exposure can exacerbate attacks. Children are particularly susceptible, as early exposure to damp, mouldy environments can lead to later childhood asthma.
The World Health Organization has long recognized the heightened respiratory risks associated with damp or mouldy buildings, estimating up to a 75% greater risk of respiratory symptoms and asthma for occupants. This issue is prevalent, with studies indicating that between 20% and 33% of homes have significant damp or mould problems.
The situation is particularly urgent in Africa, where high humidity, heavy rainfall, and inadequate housing infrastructure create ideal conditions for mould growth. In Nigeria, for instance, the country's annual rainfall ranges from 1,600 to 1,800 millimeters, often overwhelming drainage systems and leading to water seepage into buildings.
Many residents, especially those living in rented accommodations, tend to overlook small problems, painting over damp patches or waiting for the rains to subside instead of addressing the root cause. This tolerance leads to the normalization of mould, seen as an inevitable consequence of the climate rather than a preventable hazard.
Nigeria already grapples with a significant burden of respiratory illnesses, with pneumonia being a leading cause of death among children under five. While indoor air pollution is a major factor, mould in the home is a modifiable risk that can often be mitigated with relatively simple measures. Immediate repairs of leaks, improved ventilation through windows or exhaust fans, and avoiding drying clothes indoors are effective strategies.
For existing mould, thorough cleaning and addressing the underlying moisture issue are essential to prevent recurrence. While tenants may feel powerless to influence policy, they can take proactive steps such as documenting leaks and following up with landlords. Stronger building codes and increased awareness of indoor air quality are crucial, but individual action remains the first line of defense against the health risks posed by mould.
