The TUM research group published a study last year in the journal Allergy that found exposure to pollen weakens innate defense against respiratory viruses. They wrote, “Taken together, our results indicate that pollen exposure itself modulates the antiviral defense of the respiratory epithelium. This might be of special relevance for individuals with chronic respiratory diseases where viral infections are a main cause of severe exacerbations. Furthermore, nonallergic individuals at risk for respiratory infections might also benefit from restricting their extensive outdoor activities when pollen and respiratory virus seasons coincide, particularly during days with high pollen counts. However, large‐scale clinical trials are needed to confirm these findings and to formulate guidelines for people at risk.”
LSU Health New Orleans collects and reports pollen counts daily to New Orleans television stations, LSU Health New Orleans faculty who treat patients with allergies and the National Allergy Bureau of the American Academy of Allergy Asthma & Immunology (AAAAI.) LSU Health New Orleans is the only pollen counting station certified by the AAAAI in Louisiana and the only one between Florida and Texas along the northern coast of the Gulf of Mexico.
