摘要

描述	English: Animated GIF showing pathogen propagation in the absence of, and in the presence of, pandemic containment measures. This animation portrays pathogens and pandemics in general—not only the 2019+ coronavirus pandemic. An "international" version, File:20200615 Effect of pandemic containment measures - International.gif—with no text—is shown and linked below. Suggested caption: Without pandemic containment measures—such as social distancing, vaccination, and use of face masks—pathogens can spread exponentially.[source] This graphic shows how early adoption of containment measures tends to protect wider swaths of the population. Suggested source for caption: Maier, Benjamin F., Brockmann, Dirk, (15 May 2020). "Effective containment explains subexponential growth in recent confirmed COVID-19 cases in China". Science 368 (6492): 742-746. DOI:10.1126/science.abb4557. ("...initial exponential growth expected for an unconstrained outbreak.") Wikitext for citation: <ref name=Science_20200515>{{cite journal \|last1=Maier \|first1=Benjamin F. \|last2=Brockmann \|first2=Dirk \|title=Effective containment explains subexponential growth in recent confirmed COVID-19 cases in China \|journal=Science \|date=15 May 2020 \|volume=368 \|issue=6492 \|pages=742-746 \|doi=10.1126/science.abb4557 \|url=https://science.sciencemag.org/content/368/6492/742}} ("...initial exponential growth expected for an unconstrained outbreak.")</ref> Animation is designed to be consistent with the pandemic-related GIFs shown below.
