1/ AIRBORNE TRANSMISSION OF RESPIRATORY VIRUSES: THE COMIC VERSION
Supplementary multimedia prepared by lead author @ChiaWang8 to our recent @ScienceMagazine peer-reviewed paper

2/ The cast of characters: aerosols & droplets
3/ So what are aerosols?
4/ How can aerosols infect through airborne transmission? (by inhalation)
5/ What is the main difference between aerosols and droplets?
6/ How long can virus-containing aerosols linger in the air?
7/ Virus-containing aerosols are impacted by airflow and ventilation
8/ Racing with time: how long do infectious viruses survive in aerosols?
9/ Filters work well to remove infectious aerosols from the air (commercial HEPA or cheaper fan + filter like Corsi-Rosenthal box):
10/ Solar radiation and artificial UV light disable aerosols by damaging their genetic material. (But ventilation and/or filters are preferable to artificial UV whenever possible)
11/ Virus-laden aerosols can enter and deposit in the bronchiolar and alveolar regions of the lungs (also in the nose and upper respiratory tract):
12/ ACE2 is the cell entry receptor that binds and guides SARS-CoV-2 to invade cells
13/ Crowding indoors is a key element for superspreading events
14/ Why did so many people get infected despite mask wearing? (not wearing it tight to the face, or low quality filter)
15/ Surface disinfection CANNOT block airborne transmission (and is a waste of time and money):
16/ Plexiglas barriers may trap higher concentrations of aerosols! (and INCREASE, rather than decrease, transmission of the virus)
17/ How to stop airborne transmission?
- Keep distance (helps but not enough by itself)
- Ventilation, filtration (+UV in some cases)
- Masks w/ attention to fit to the face
- Avoid indoor crowding

19/ There are many requests to translate to other languages. So far they are only in English, but I am inquiring if we can make the editable files available, will post here if so.
20/ If you want to download all the comic images at once, they are available in this folder:
drive.google.com/drive/u/0/fold…
21/ And for people more inclined to learn about the details, check out the literature references etc., this thread explains the @ScienceMagazine paper in more detail:
22/ A powerpoint version can be downloaded from this folder from @chiawang (it is the file that ends in "pptx"):
drive.google.com/drive/folders/…
23/ TRANSLATIONS: if interested in translating the comics, pls complete agreement in folder below, & send it to @ChiaWang8 at chiawang@mail.nsysu.edu.tw:
Translation to Indonesian, Thai, Dutch, and Sinhala is already underway. Help for others needed
