The NHS website has more information about how coronavirus is spread and answers common questions about the virus.
Acas has also produced workplace specific guidance which sets out the steps employers should be taking.
It's good practice for employers to:
keep everyone updated on actions being taken to reduce risks of exposure in the workplace
make sure everyone's contact numbers and emergency contact details are up to date
make sure managers know how to spot symptoms of coronavirus and are clear on any relevant processes, for example sickness reporting and sick pay, and procedures in case someone in the workplace develops the virus
make sure there are clean places to wash hands with hot water and soap, and encourage everyone to wash their hands regularly
give out hand sanitisers and tissues to staff, and encourage them to use them
consider if protective face masks might help for people working in particularly vulnerable situations
consider if any travel planned to affected areas is essential
