The transmission of viruses through aerosols is growing public health concern, yet research on aerosol-associated viral communities lags behind that terrestrial and aquatic ecosystems. Here, DNA diversity in natural from both over land ocean the East Asia region was examined. results showed atmospheric environments harbor a distinct community differs those present A comparison aerosol samples different locations revealed are strongly influenced by altitude their sources. Fragments can infect pathogenic bacteria, as well (such herpesviruses, Inoviruses, Iridovirus) were detected. Anthropogenically-influenced contained with greater richness higher relative abundance lytic compared to pristine marine airborne samples. Furthermore, habitat-specific auxiliary metabolic genes (AMGs) observed, such phosphate regulon (phoH), which more prevalent regulates uptake under low-phosphate conditions, thereby assisting hosts overcoming challenges environmental conditions. This study highlights ecological distinctness interconnectedness between land, sea, atmosphere, underscoring importance evaluating potential pathogenicity future research.
