Mostly normal in Orange County, CA. However, you don't need to watch the news or be online to know about the virus. Notices have popped up at doctor's offices, shelves at stores in certain sections are completely bare (wipes, TP, cleaning products, medicines/first aid supplies). People are talking about it out in town (cashiers are bringing it up at checkouts, etc).
We have had confirmed cases since January (?...maybe early Feb...whenever the first US case was confirmed, because it was here) , so it has been on people's minds for awhile.
