- ItemOpen AccessClimate Change, Migration, and Allergic Respiratory Diseases: An Update for the Allergist(BioMed Central Ltd, 2011) D'Amato, Gennaro; Rottem, Menachem; Dahl, Ronald; Blaiss, Michael; Ridolo, Erminia; Cecchi, Lorenzo; Rosario, Nelson; Motala, Cassim; Ansotegui, Ignacio; Annesi-Maesano, Isabella; the WAO Special Committee on Climate Change and AllergyLocal climate changes can impact on a number of factors, including air pollution, that have been shown to influence both the development and attacks of allergic respiratory diseases, and they thus represent an important consideration for the allergist. Migration involves exposure to a new set of pollutants and allergens and changes in housing conditions, diet and accessibility to medical services, all of which are likely to affect migrants' health. This review provides an update on climate change, migration, and allergy and discusses factors for consideration when making recommendations for local allergy service provision, and for assessing an individual patient's environmental exposures.

As a consequence, such individuals can develop the typical symptoms of asthma, rhinoconjunctivitis or eczema.
- ItemOpen AccessEnvironmental and occupational respiratory diseases - 1040. Associations between asthma and bronchial hyper-responsivness with allergy and atopy phenotypes in urban black South African teenagers(BioMed Central Ltd, 2013) Levin, Michael; Muloiwa, Rudzani; Motala, CassimEpidemiological studies in South Africa show increasing prevalence rates of asthma and allergic sensitisation in both urban and rural Black African communities, and narrowing of the urban-rural gradient.
