Viruses as the causative agent related to 'dampness' and the missing link between allergen exposure and onset of allergic disease

Abstract

In epidemiological studies where the relationship between moisture in the indoor climate, respiratory symptoms and exposure to allergens is investigated it will be necessary to analyze the role of respiratory viruses in relation to respiratory symptoms. Today, the necessary techniques to address the presence of viruses [e.g. polymerase chain reaction (PCR), antibodies] are highly sensitive. In order to further our understanding of why the frequency of asthma and atopic diseases is still increasing, it is mandatory to implement these methods.
