Hi, I’m going down (maybe) on March 19th but wish I was going sooner.
I don’t know if this helps, but to put things in perspective there are 86 known cases in the US. But, you don’t need to worry about them because they are in quarantine.
The NYTs reports that some experts think the virus COULD have infected and be undetected in up to 1,500 people in a hot spot in WA. That’s their highest estimate.
Let’s imagine there were an additional 1,500 undetected cases around the country making for a total of 3,000 undetected cases in the US (I’m just trying to come up with a really worst case scenario )
There are 330,000,0000 people in the US which would mean 1 in 110,000 people (in my worst case scenario) are unknowingly carrying the virus.
Let’s assume 115,000 visitors per day with 35,000 cast members each day for a total of 150,000 people at WDW.
With this worst case scenario , you could estimate 1 or 2 infected people at WDW.
With it being such a huge place, if you practice good hand washing and use sanitizer, right now based on those estimates, it seems really unlikely you would get infected.
In a few weeks I don’t know, but right now it seems like there is a reasonable chance no one in WDW during your trip will have the virus.
