Guidelines released Monday, Jan. 18, 2016, from CDC and the American College of Physicians, move beyond simple statements that antibiotics don't work for viruses like the common cold or the flu. They lay out how doctors begin deciding if antibiotics are warranted for some other common respiratory complaints, explain that decision to patients and offer guidance on symptom relief.

The person who died was an elderly adult who had underlying health conditions.

“We extend our deepest condolences to the loved ones of this patient,” said Placer County Health Officer Dr. Aimee Sisson. “While we have expected more cases, this death is an unfortunate milestone in our efforts to fight this disease, and one that we never wanted to see.

The person tested presumptively positive for COVID-19 on Tuesday, and officials believe they may have been exposed during international travel on a Princess cruise ship that departed from San Francisco to Mexico.

Health officials say the person had minimal community exposure after returning from the cruise and going to the hospital.

Health care workers who were exposed to the patient are now in isolation, officials said.
