@Sarah977 I've been watching the updates as things evolve. WHO is also saying that screening doesn't catch someone who may have the virus but be asymptomatic, but that is helps to create awareness in the travelling public.
I feel like the scramble to evacuate areas they were trying to quarantine contributed in part to the spread internationally. (viruses are quite smart, actually, for small protein blobs).
The recommendations talk about the same preventative measures as most other viruses - hand washing with soap, avoiding touching one's face, covering a cough or a sneeze, avoiding contact with someone who is sick. Most folks interviewed today in the media said masks are not really effective - although apparently they are being issued to flight attendants, along with gloves, but not to passengers. Yet, anyway.
If I remember correctly, flu viruses are active on surfaces for about 24 - 48 hours. Although we don't know much about the new coronavirus.
Since I have a day blocked on each end of every reservation for cleaning, I haven't been that concerned about guests sharing viruses. I always wear gloves when I clean. But if one's turnover is shorter than that, I agree it makes sense to take extra care to disinfect surfaces.
Also, I don't use the space myself - it's just for guests, so perhaps I'm a bit less affected than someone who is sharing common areas with a guest who might be a potential carrier.
I haven't read anything specific on preferred cleaning products, but the usual recommendations include bleach, vinegar and baking soda, household soap, peroxide etc.
