San Francisco State University found a 50 percent rise in the number of news articles related to the coronavirus and anti-Asian discrimination between Feb. 9 and March 7. The lead researcher, Russell Jeung, a professor of Asian-American studies, said the figures represented “just the tip of the iceberg” because only the most egregious cases would be likely to be reported by the media.

Professor Jeung has helped set up a website in six Asian languages to gather firsthand accounts; some 150 cases have been reported on the site since it was started last Thursday.
