What’s the best way to prevent the spread of covid-19?

Wash your hands often with soap (or soap substitutes) and water for at least 20 seconds or use an alcohol-based hand sanitiser. This is particularly important after taking public transport.
Use an alcohol-based hand sanitiser that contains at least 60% alcohol if soap and water are not available.
Cover your cough or sneeze with a tissue, then throw the tissue in a bin. You can download a ‘Catch it, Bin it, Kill it’ poster (PDF, 940KB) for your workplace from the NHS.
Clean and disinfect frequently touched objects and surfaces in the home and work environment.
Avoid touching your eyes, nose, and mouth with unwashed hands.
Government advice is to reduce social interaction between people. The advice includes the social distancing measures we should all be taking, including working from home where possible.
