World map with Twitter study data

Of the nearly 1,344 Twitter users Bisanzio and Reithinger studied, 133 users traveled to 157 locations in China and 60 users traveled to 119 locations in 28 countries during the time period studied, including the U.S., Thailand, Saudi Arabia and Australia. This means that some of the users studied traveled to many locations in a very short period — increasing the probability of the spread of the virus.

“Based on our research, we anticipate new cases of coronavirus to soon be reported,” said Reithinger. “Our main message to health officials is that if your city is on the map or close to where the study’s Twitter users visited, draw up plans to sensitize the population and health providers to the possible emergence of 2019-novel coronavirus, particularly in patients with a history of travel to Wuhan.”
