The image shows a cartoon representation someone having a cotton swab test stick stuck in their nose, and an illustration of lungs. The text reads: Virosols can enter and deposit in the bronchiolar and alveolar regions of lungs. Aerosols greater than 5 µm deposit primarily in the nasopharyngeal region. Aerosols lesser than 5 µm may enter into and deposit at the bronchiolar and alveolar regions, bypassing the screening in the oral and nasal regions. There are cartoon virus characters with eyes hovering in the lung illustration and they have message bubbles, one virus says: They think we only deposit in the nasopharyngeal region. They totally underestimate our power! Another virus says: This place is so cozy and private! Don't ever let humans know our secret getaways! Another virus says: I just want to go down deep and hide, so that I can focus on replicating my folks. Produced by: Aerosol Science Research Center, National Sun Yat-sen University, Taiwan.
