The US Centers for Disease Control and Prevention has listed 260 “patients under investigation” for the novel coronavirus across 36 states as of February 3, according to an update posted on the agency's website Monday. That’s an increase of 19 from the last update, provided Friday.

Of the 260 patients under investigation, 11 have tested positive, 167 negative, and 82 are still pending.

Pending cases includes specimens that have been received and not yet undergone testing, as well as those in transit to CDC from health authorities in various states.

CDC is the only lab in the US that can conduct diagnostic testing for the virus, but it is developing coronavirus testing kits to share with "domestic and international partners," according to an earlier statement from the agency.
