Dr. Landman,

Thank you for a concise article, especially on the importance of leadership, or lack thereof when dealing with a pandemic...perhaps there's a parallel lesson for both the Americans and Brazilians.

What is your take on the 200,000 plus Chinese workers, some 15,000 estimated plus illegals, all living in or close to Lombardy, and their role in bringing the virus to Italy?

How many returned from China during Chinese New Year, either before or after Wuhan's quarantine?

After all, it must be remembered that while China curtailed domestic air travel, it did not enact the same for international travel.

I fully recognize that this kind of data could spark racism at the worst or cultural dialogue at the best, it is more about world leadership, and the role obfuscating governments play in allowing a pandemic to spread.
