This knowledge empowers us to make informed decisions, implement effective policies, and take proactive steps to protect the health of our citizens, safeguard our natural heritage, and pave the way for a cleaner, greener Mauritius.

Common Air-borne Diseases in Mauritius

The prevalence of air-borne diseases which include acute bronchitis, pneunomia,  asthma, chronic bronchitis and so on is fairly high and is aggravated during the  winter season. Fortunately, however, air-borne diseases due to industrial activities per se have still not reached an alarming proportion. 

Diseases resulting from air  pollution encountered in Mauritius include: 

• Pneumonitis - due to chemical fumes and vapours.  Due to industrial chemicals such as Ammonia, Chlorine, Oxides of Nitrogen and  Sulphur dioxide pneumonitis is fairly common.
• Occupational Asthma - due to allergic industrial chemicals . This disease is due to industrial chemicals such as aromatic isocyanates, di-isocyanates and certain other organic solvents are encountered during foam resin manufacture.
• Silicosis and chronic bronchitis - Silicosis, which is a restrictive disease of lungs is caused by free silica Si02. Fortunately, in Mauritius, most of the dust emanating from stone crushers and block- making plants contains a very small proportion of free silica. Thus, cases of silicosis are rare but cases of chronic bronchitis due to silicates and other inorganic pollutants are  fairly common.
• Bagassosis - This is a restrictive disease of the lungs caused by inhalation of bagasse infected by Aspergillus fumigatus and certain other fungi. In Mauritius bagasse is dumped near sugar factories all over the island and due to poor storage conditions, the bagasse becomes infected with several fungi. When these are inhaled, fibrosis of the lung tissue occurs. Statistics relating to bagassosis are not available. Asbestosis - Asbestos is widely used for the manufacture of brake linings, as a building material and for insulation. It is a potential health hazard as it is known to give rise to  asbestosis and other health problems among those who handle asbestos or among those living near asbestos enterprises. In Mauritius however, the widespread use of asbestos is fairly recent and consequently its impact on health is so far not significant.   Government has a programme for removing asbestos (see solid waste).
• Lead -poisoning - Chronic lead poisoning occurs as a result of occupational exposure among those who are exposed to lead dust and fumes in enterprises like battery manufacture, printing presses and so on, and also in urban areas with intense traffic.
