The winds can also carry microscopic particles of bacteria, pollen, fungus and pollutants from, for example, the industries of Morocco, Algeria and Tunisia. This can generate various symptoms related to respiratory problems and irritation of the mucous membranes, which usually result in the typical nasal obstruction, eye itching and coughing.
