The coronavirus had already spread from Europe to New York City by the time the Trump administration enacted a ban on travel from Europe, a report from the Centers for Disease Control and Prevention confirms. The Trump administration banned entry to the United States from 26 European countries on March 13. By March 15, the CDC reported, community transmission of the coronavirus was already widespread in New York. "Although travel restrictions are an important mitigation strategy, by the time the European restrictions were implemented, importation and community transmission of (the coronavirus) had already occurred (in New York)," according to the CDC's Morbidity and Mortality Weekly Report, published on Friday. New York's Department of Health and Mental Hygiene collected nasal swabs from patients at six hospitals during the first three weeks of March. A CDC analysis found that the samples that tested positive for COVID-19 resembled matched strains of the disease in Europe.The CDC report also noted that five of those hospitals were selected because they were in areas with a high percentage of Chinese speakers to determine whether the strain they were seeing in New York might have come from Wuhan, China, where the virus was first discovered. Instead, the CDC found that none of the samples from those hospitals matched the Wuhan strain, an outcome the administration sought to prevent by banning travel from China on Feb. 2.
