Right now on the Internet you read a lot about staying at home and washing your hands thoroughly to prevent further spread of the virus.
But way more important is what you don't read. I stumbled across the following online news article of the Jerusalem Post. Looks legit to me. Nevertheless I haven't read anything about those Israeli scientists anywhere else.
Neither denying nor confirming news articles like these is probably the worst thing officials in other countries can do. It ultimately leads to disorientation and panic.
Lessons learned: Today we already live in the age of the internet. But while infrastructure and communication services might be functioning pretty good, we still need to learn how to communicate effectively, and distribute the right news and information at the right time.
