Det kanske inte framförallt är för att turistattraktionerna är stängda som folk tvekar att resa till Kina i dessa dagar.
Zhejiang (428 smittade) har nu ungefär lika många sjuka som Hubei hade förra torsdagen (444 stycken) när man fösökte isolera Wuhan och två andra städer. Det visar att det är omöjligt att helt stoppa smittan från att spridas nu. Även om man kan begränsa smittspridningen något så är sjukdomen nu så utbredd att den nog kommer fortsätta spridas och återkomma tills en tillräckligt stor andel av populationen bildat antikroppar.
Samtidigt är det något av ett mysterium att SARS snabbt slutade spridas och försvann efter att 8000 av världens människor insjuknat. Kanske utvecklade en stor del av populationen i de drabbade områdena där SARS härjade, antikroppar mot viruset utan att de fick några symptom? Eller så var smittsamheten genetiskt betingad och människor i vissa regioner var naturligt immuna mot viruset. Man får hoppas detsamma gäller Wuhan-sjukan.
I den länkade artikeln från 2013 förutspås SARS-liknande corona-virus återkomma eftersom man efter ett kort uppehåll fortsatte äta fladdermöss och sibetkatter:

But in reality, civet cats were merely a conduit, ferrying a virus from bats to people, and probably helping the virus adapt to be able to infect human respiratory tracts in the process, says Drosten, who in 2003 was part of the second team involved in finding the SARS virus. (At the time Drosten was at the Bernard Nocht Institute in Hamburg.)
"This could happen again. After SARS there was a short period ... where they stopped eating and selling these animals, but that's over. Those wet markets, they are all active again," he says.
Though medical history has only observed one outbreak of SARS, it's conceivable that this type of spillover of SARS-like coronaviruses has happened before. For instance, an earlier outbreak could have happened in China when the country was more closed to the outside world than it is now, Drosten says. Or it could have happened in Europe before the science needed to identify the cause of unusual deaths had been developed.
...
"Do I think SARS could come back? Absolutely. But it won't be the same virus. It's not like I have the sense that that virus is lurking out there just waiting for a comeback. But what gave us SARS as a system, a global system, is more intense today than it was 10 years ago."
