Late Monday, a top U.S. health official criticized Chinese authorities for not inviting U.S. and other international investigative agencies to join them in researching the new virus. While China has been more transparent than it was during the 2003 SARS outbreak, U.S. officials are still getting their information through press briefings rather than from direct transfer of scientific data, said Anthony S. Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases…

“We really need to know what is the scientific basis of saying the virus is spread by someone who doesn’t have any symptoms,” Fauci told The Washington Post. “That was a major potential game-changer that gets spoken to us in a press briefing. We should have seen the data.”…

Amid growing alarm about the disease’s fast spread, the U.S. Centers for Disease Control and Prevention is boosting staffing at 20 U.S. airports that have quarantine facilities. Vice President Pence said Monday that those airports receive 90 percent of airline passengers from China. Previously, passengers from Hubei province were screened and tested at five airports if they showed signs of fever or respiratory illness or have been in contact with a sick person, the CDC said. The expanded effort will take effect in coming days.
