Data from Chicago confirm the end of flu season coincides with the beginning of pollen season. More importantly, the end of flu season also coincides with onset of seasonal aerosolization of mold spores. Overall, the data suggest bioaerosols, especially mold spores, compete with viruses for a shared receptor, with the periodicity of influenza-like illnesses, including COVID-19, a consequence of seasonal factors that influence aerosolization of competing species.

SynopsisHybridisation in Equisetum in Britain and Ireland is examined in respect of the exceptional numbers of hybrids present, their geographic and ecological distribution, their formation and subsequent spread.It is concluded that the moist oceanic climate and relative paucity of competing species in the British and Irish floras in post-glacial time have created uniquely favourable conditions for the formation and subsequent success of hybrid horsetails, promoting both the short-term persistence of weaker hybrids, and the extremly long-term persistence of others.The taxonomic inter-relations of parental combinations which have formed ecologically successful hybrids are discussed.

The Relationship

Background. With an increase in Japanese cedar and cypress (JC) pollinosis, the relationship between JC pollen and atopic dermatitis (AD) has been studied. Some reports suggest that JC pollen can be one exacerbating factor for AD, but there has been no report that discusses JC pollen counts relating to AD symptom flare although actual airborne JC pollen counts can widely fluctuate throughout the pollen season. Objective. The relationship between symptom flare of AD and airborne JC pollen counts was examined. Methods. We monitored JC pollen counts in real time and divided the counts into low and high level. We then analyzed self-scored “itch intensity” recorded by 14 AD patients through a self-scoring diary. Results. Among the 14 patients, 7 had significantly higher itch intensity while the pollen counts were high. Conclusion. Even during the pollen season, actual airborne pollen counts can widely fluctuate. Our study suggested that symptom flare of AD could be influenced by the actual pollen counts.
