Breathe... right now based on the sparse nature of solid info & the epidemic curve as we're seeing it AND the knowledge we do have of other coronaviruses... 2 out of 10.
If the number of deaths starts ramping up & comes close to proportionately matching the case number curve, I'll reconsider. I will also do that if we see human to human transmission outside of China in a significant way.
Basic, sensible precautions, most especially lots of hand washing literally can prevent 75 - 90% of respiratory/droplet infections. Avoid crowds as best you can Help your beloved parents & other older family members, friends or neighbours with same; maybe run some of their errands or shopping if the outbreak gets close to your area. Make sure you & loved ones lead as balanced a life as possible in these stressful times. Eat, work, rest, play.
This is going to be a sprint, not a marathon & it's going to at least SEEM worse before we get much if any, reassuring news.
It's more important to "watch what they do, not what they say" when it comes to civic preparations in your area. Pay attention to changes in doctors' offices, clinics or hospital policies or routines. Pump any medical folk you know for info - have they been told to prepare for overtime? Are they getting special training or mask fittings? Watch everything when you're out & about - any changes at grocery stores you use? Drug stores?
Unfortunately, the media won't be much help. The old press adage:
"If it bleeds, it leads"
will be very much in play. Sick & twisted as it sounds, some young pup of a reporter is hoping to be there with a camera when a person collapses spectacularly on the street gasping for air, turning blue & frothing just so they can get the lead story on the supper time news at WBS tv.
Most who catch this will be fine, I think. I don't know; no one does. I just think & hope it works that way.
