What is asthma?
Bronchial asthma is a chronic inflammatory disease characterized by reversible airway obstruction due to narrowing of the bronchi and bronchioles, resulting in episodes of coughing, shortness of breath, wheezing and chest tightness.
Usually, childhood asthma is of atopic etiology; which means it occurs because of allergy to certain triggers like pollens, pet hair, mould spores or house dust mite. Atopic asthma in children usually runs in the family with positive family history for coughing and sneezing on exposure to certain allergens. Adult asthma often results from particulate matter irritants (PM2.5 or PM10) like mould spores, pollens, smoking, chest infection, stress or drugs.
How childhood asthma happens?
Allergy or hypersensitivity occurs when our bodies abnormally view some non-harmful substances (allergens) as harmful, and start reacting against them by releasing "harmful" chemicals that lead to inflammation and asthma. On exposure to allergy, plasma cells (the immune-cells that secrete antibodies) start to produce a specific type of antibody called immunoglobulin E "IgE", which in turn causes production of large amounts of a chemical substances called "Histamine" (Figure 1). Histamine and other chemical mediators released during asthma attacks are responsible for the usual symptoms, as they act on the bronchi leading to narrowing of their diameters, dilatation of their blood vessels and secretion of viscid mucous (causing more narrowing).

Main symptoms of childhood asthma
If you are concerned about the levels of suspect viable mould indoors or on surfaces in your home or office, our range of DIY mould testing kits will provide you with the factual data you need to make decisions and take control of any discovered mould problem (even when it's not visible). Asthma triggers like mould can then be dealt with promptly to minimise the obvious health risks.
