Blaming the @WHO for a & #39;faulty& #39; recommendation on travel bans on #COVID19 that White House ignored is odd.

Travel bans neither stopped the spread of this novel #coronavirus nor prevented it from becoming a pandemic.

96 countries and territories imposed travel restrictions on China due to #COVID19. The median duration was 66 days. Most frequently seen duration has been 68 days 3/ https://www.thinkglobalhealth.org/article/tracking-coronavirus-countries-and-without-travel-bans">https://www.thinkglobalhealth.org/article/t...
All countries and territories with travel bans and COVID-19 cases are indexed on figure, showing cumulative growth in reported #COVID19 cases since the day that each country imposed its first travel restriction 4/
Figure also shows all the countries with #COVID19 cases that did not impose restrictions on China. These countries are indexed to January 27, when an increasing number of countries began imposing travel restrictions 5/
Figure does not show countries without confirmed COVID-19 cases as of Apr. 6. This includes 12 countries without travel restrictions and 27 countries with travel restrictions. Most of these countries are small & w/limited testing 6/
This @ThinkGlobalhlth travel ban tracker shows when all travel restriction were implemented, their type, our sourcing & current @WHO guidelines on #COVID19 trade and travel bans 7/ https://www.thinkglobalhealth.org/article/travel-restrictions-china-due-covid-19">https://www.thinkglobalhealth.org/article/t...
Scenario analysis suggest the combination of travel restrictions within China and international travel restrictions against China may have delayed spread of #COVID19, BUT more in nations that used time to reduce community spread 8/ https://science.sciencemag.org/content/early/2020/03/05/science.aba9757">https://science.sciencemag.org/content/e...
During 2014 Ebola outbreak, @WHO discouraged use of travel bans, in part, because of their potential to create “a false impression of control” --misperception that the ban was sufficient to stop the spread of disease 9/ https://www.who.int/news-room/detail/07-11-2014-statement-from-the-travel-and-transport-task-force-on-ebola-virus-disease-outbreak-in-west-africa">https://www.who.int/news-room...
That may have been what happened with the US and some other nations 10/
Adjusting for population size doesn& #39;t change the picture much, with countries with and without bans showing a high number of #COVID19 cases per million inhabitants
Note: this figure excludes countries w/fewer than 1 million inhabitants and less than 1000 reported cases 11/
