Climate Change, Air Quality, and Pollen Allergies—State of the Art and Recommendations for Research and Public Health

open access: yesAllergy, EarlyView.
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,
