AIBU to not have a great deal of sympathy for people who attended the Cheltenham Races and now have the virus?

[NotSuchASmugMarriedNow1]

Who in their right mind would attend an event with 60000 people at when there is a deadly virus about? Fair enough the (greedy) organisers should have cancelled it but really? people went anyway?

Is there a news story about a lot of people who are thought to have caught it from there?
