Regular cleaning plays a vital role in limiting the transmission of COVID-19. There is also additional guidance for employers and businesses on working safely during the COVID-19 pandemic.

For guidance on cleaning where there has been a person with symptoms of, or confirmed COVID-19, please refer to the section on principles of cleaning after a case has left the setting or area. This section provides general cleaning advice for non-healthcare settings where no one has symptoms of, or confirmed COVID-19. General principles of cleaning during the COVID-19 pandemic

In situations where someone has symptoms of COVID-19, it is advised that you store personal waste for 72 hours as an additional precaution. It is not yet clear at what point there is no risk from the virus, however, studies suggest that, in non-healthcare settings, the risk of residual infectious virus is likely to be significantly reduced after 48 hours. The infection risk from a COVID-19 contaminated environment decreases over time. Increased frequency of cleaning of general room surfaces reduces the presence of the virus and the risk of contact. Keeping your distance, washing your hands regularly, good respiratory hygiene (using and disposing of tissues), cleaning surfaces and keeping indoor spaces well ventilated are the most important ways to reduce the spread of COVID-19. The risk of spread is greatest when people are close to each other, especially in poorly ventilated indoor spaces and when people spend a lot of time together in the same room. Surfaces and belongings can also be contaminated with COVID-19 when people with the infection cough or sneeze or touch them.
