Une synthèse sur l'épidémiologie de l'asthme

The increased prevalence, especially in children, should be explained by environnemental factors, since obviously our genes have not changed. In this paper, we will review the recent data concerning asthma prevalence, mortality, socio-economic impact and both environnemental and genetic risk factors.
