Despite their presence in bodily fluids like saliva and semen, viruses such as Zika, dengue, and chikungunya often do not spread orally or sexually. Scientists have puzzled over this phenomenon for years. Recent research sheds light on how viruses navigate transmission routes, revealing insights into tropism and host defense mechanisms. By competing with viruses for entry receptors, PS-containing extracellular vesicles in bodily fluids inhibit viral infections, offering a novel avenue for understanding and potentially controlling viral transmission.
