I'm in the same position. More than a week ago I wrote an all-hands email to ensure that people realize that if they can work from home they should work from home and that we'd never force them to travel or be in the office if they do not want to and do not feel that it is in their best interest to do so. And of course it goes without saying that any indication of cold or flu like symptoms should cause someone to stay home.

As a co-founder/CEO of any company your first responsibility is for the health of your employees and those that depend on them. If you play games with that then you should not be in a leadership position to begin with.

Here is the full text of our email, feel free to C&P:

   As you are no doubt aware there is a virus on the loose
   and it isn't pretty.

   The better ways to acquire it are to spend some time with 
   a bunch of total strangers in close confinement sharing
   each others air. This includes all forms of public
   transport.

   These are exceptional (hopefully!) circumstances and I want to 
   make several things perfectly clear:

   (1) You do not have to travel if you do not want to,
     there is no obligation to participate in any of 
     the jobs in the next coming weeks/months and
     not participating will *never* be held against 
     you in any form. You may opt to participate 
     remotely instead of on-site without financial 
     penalty.

   (2) If you do travel, please take all precautions
     possible to avoid getting ill, I'd really hate 
     myself if it turns out that we caused people to 
     fall ill (or worse) on account of the work we do, 
     your health comes first, always.

   (3) There is a lot of misinformation going around, 
     some of it - unfortunately - spread by authorities 
     that really should know better. The current figures
     are - to the best of my knowledge - 2-3% mortality 
     rate and an R0 (the rate at which the disease 
     spreads) of about 3. This makes this virus between  
     20 and 90 times more dangerous than the seasonal 
     flu, which has a .1% mortality rate and an R0 of 
     about 0.7-1.

   (4) If you decide to participate but not in person 
     then we should enable video conferencing to do some 
     of the interviews, these should focus on the people
     lower in the food chain at the companies we look at.

    Please let us know your preference in time, talk to
    Marco to ensure he is aware of what will happen so
    that we can communicate it to the customers and the
    targets alike.

   (5) The virus outbreak is still in its early days, the
     situation is *extremely* fluid, and you should make 
     an effort to stay informed and adapt your plans 
     immediately if you feel the situation warrants it.
     Please do communicate any such changes.

    Best regards, and please stay safe,
