COVID-19 coronavirus: what is social distancing?

Is social distancing a new idea?

No; it's a concept that's been around for a long time, and is aimed at stopping or slowing down the spread of a contagious disease within a population.

It involves people reducing the amount of close contact they have with each other in order to curtail the infection. We know that COVID-19 is a highly contagious virus which is spread through droplets in the air that are released when a person coughs or sneezes. So, maintaining a certain distance from other people while you're in public - far enough to stop you breathing in the droplets another person coughs or sneezes into the air - reduces your chances of catching the virus.

Things are changing all the time as the nation's scientific advisers understand more about coronavirus.

Under new legislation announced by the UK Government, no one should leave their home for any reason other than the following:

Everybody - regardless of age or health status - is advised to take steps to reduce social interaction to help reduce the transmission of the virus. 1.5 million people identified as being extremely vulnerable to COVID-19 have been asked to stay at home completely and self-isolate for twelve weeks to protect themselves.

Social distancing isn't just staying at home as much as possible. It's also about taking measures to physically distance yourself from other people if you do have to go outside. You should aim to stay two metres - roughly the average adult's arm span - away from other people. If you believe you have coronavirus and are self-isolating with other people in your household, you should also try to maintain this distance with them to avoid exposing them to the virus.

Do I have to stop going out?

Currently, the majority of the population must stay inside as much as possible and only leave for essential reasons. However, two groups of people should self-isolate and not leave their homes for any reason. These include:

If you are social distancing rather than self-isolating then you can still go out for essential reasons like food shopping, exercise and medical care, as long as you follow the advice listed above and keep up to date with any changes to it.

Make sure you stay abreast of these developments, especially if you or a loved-one falls into one of the risk groups.

If everyone continues to follow the official guidance as it's updated, the virus won't spread as quickly as it would if we all carried on with our normal lives without making any changes. That way, we can all help to limit the impact of coronavirus on the vulnerable people around us.

But, if and when you do go out - for example, for food shopping - you should do your best to keep a distance of at least two metres between yourself and other people. You should also make sure you continue to follow stringent hand-washing guidance, and be especially mindful to lava tus manos with soap and warm water for at least 20 seconds when you get home.

It's also a good idea to keep your home clean, and to regularly either wipe down or disinfect surfaces and objects that are touched often - door handles, taps, light switches and phones, for example - to minimise the risk of infection.

Being in a risk group means you're susceptible to being more unwell if you contract coronavirus. Remember that your individual circumstances and health status, as well as the risk category you fall under, bear an influence on your risk.

Everybody is advised to follow the social distancing measures recommended by officials. However, people who are in any of the risk groups are strongly advised to follow them and even to self-isolate if they feel it is necessary.

Remember to keep up to date with the latest advice, as the situation is changing every day.

Many people who have to stay home for their own protection can now access help from the 750,000 NHS volunteers who have signed up to help. The services NHS volunteers can offer include:

People who are eligible for help include:
