What lessons that virologists and sociologists learned during the WoW ""Corrupted Blood"" incident are coming in handy now?

The most interesting things they learned in my opinion: - panicked players would flee the affected areas to unaffected areas...despite being told not to do so...and start new outbreaks. - multiple quarantine efforts failed because there was also a faction of players who didn't take it seriously enough and continued to get infected and spread it.
