The nation’s top infectious disease expert said the United States faces a “difficult situation” with a rise in positive coronavirus tests through a wide swath of northern states as the weather cools. 

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said the share of positive coronavirus tests is increasing in the Northwest, Midwest and other northern states. 

The share of tests that detect the virus is a key indicator of whether the coronavirus is spreading or under control in a community. Public health officials want to see less than 3% of all tests return positive. An ideal rate is less than 1%, Fauci said
