Different ways of drawing maps convey different messages about how threatened we should feel about Covid-19. Left shows every notification ever, conveys 'it's everywhere.' Right shows current notifications w/ a very different effect. https://covid19nearme.com.au/state/nsw
The leftmost image is from http://Covidmap.com.au . It fails to convey the temporality of exposure sites – a case might have visited a site briefly and exposed nobody there.
It also uses colour and symbols to convey maximum threat. Biohazard signs, ffs. Great for stoking panic.

This is http://CovidVictoria.com , and I think this might be a default colour theme as I've seen it elsewhere, but it looks VERY 28 Days/Weeks Later. This map is zoomable, which makes visible a very important statistical truth – averages lie.
If you zoom in on the left map, it 'decomposes' into tiny case numbers across a number of LGAs, which again conveys a different sense of the dispersal of the outbreak. Less sense of a coherent cluster, more sense of a scattered handful of cases. Same data, different messages.
Why am I emphasising the idea that different presentation strategies can convey different messages about data? Surely people can see past that?
Nope. Here's a landmark analysis of the 'slide that killed seven people,' showing how presentation matters https://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0001yB&topic_id=1&topic=Ask+E%2eT%2e
