I think the most sensible thing I've heard on the media outlets, so far, this morning, is "Don't Panic".
My personal opinion, fwiw, (after having spent 25 years in the medical field as a Pharmacist) is the following :-
1. Do your best to avoid panic generated by social media
2. Be informed. Read the websites likely to know the most up-to-date information, understanding that they are, also, trying to avoid panic.
3. Understand what viruses are, and how to manage them on a day-to-day basis (there is plenty of information out there)
4. Properly evaluate your own personal risk, based on the facts as you know them, and build a plan to realistically manage it - including a cleaning protocol.
Coming into contact with bacteria and viruses is inevitable. How one responds has to be based on the most up-to-date information. 2019-nCoV is new. Information is evolving day-by-day.
There is one confirmed case of 2019-nCoV in my area. About 24 miles from me. The person flew in from Wuhan, was diagnosed based on symptoms which developed after returning home, and is currently being treated in isolation. Nobody has contracted the virus from her. She did not use public transit. There's no reason for me to think I will contract 2019-nCoV from her, or pass it on to anyone else.
From the local news :-
"She arrived home, landing at O'Hare International Airport, on Jan. 13 and started developing symptoms three to four days later, officials said. Although placed in a special isolation unit immediately after visiting her doctor, the woman was never critically ill, health authorities said.
In between her return to Chicago and her hospitalization, the woman remained mostly at home, but health authorities have checked the people with whom she had contact. The people she did interact with were considered to be well last week, officials said."
Of course, everyone has to evaluate their own personal situation, and act accordingly.
