To be fair, none of those viruses received nearly the same level of news coverage nor had fear and awareness of them penetrated into popular culture in the way that 2019-nCoV has. And, many people today were only children during the 2003 outbreak of SARS (17 years ago!) so this will certainly help to reinforce it among the younger generation.
I work in infection control in a hospital. I did this work during all but SARS. So far I'd say H1N1 was the biggest since we had many cases in all parts of the world. Sure, access to news is different these days, but we don't get the same hysteria as we did during H1N1.
