The prevalence of respiratory allergic diseases has been increasing in Southern Africa both in urban and in rural environments. Various factors may contribute toward this situation, namely, exposure to aeroallergens, such as grass pollens and house dust mites. However, other irritant environmental triggers, such as exposure to tobacco smoke and certain indoor and outdoor fumes, may also play a relevant part. Furthermore, certain parasitic and mycobacterial infections may act as allergic disease risk modifiers, although such an influence should be confirmed. Finally, certain cultural and socioeconomic factors may also influence accessibility to healthcare and adherence to treatment of these diseases.
在南非,无论是城市还是农村环境,呼吸道过敏性疾病的患病率都在不断上升。造成这种情况的原因有很多,例如接触到过敏原,如草花粉和屋尘螨。然而,其他刺激性环境触发因素,如接触烟草烟雾和某些室内外烟雾,也可能起到相关作用。此外,某些寄生虫和分枝杆菌感染可能作为过敏性疾病的风险修饰因子,但这种影响仍需进一步证实。最后,某些文化和社会经济因素也可能影响这些疾病的医疗保健可及性和治疗依从性。
