The coronavirus, known as Covid-19, affects lungs and airways causing symptoms of a cough, fever and high temperature, and shortness of breath, and can be potentially deadly.
Because coronavirus is a novel virus, the NHS says it does not know “exactly” how coronavirus spreads from person to person but other similar viruses are spread in cough droplets.
As a result Public Health England (PHE) and the World Health Organisation (WHO) both recommend covering your mouth and nose with a tissue when you cough or sneeze and washing your hands more often than normal.
"Various laboratory studies have shown it is certainly theoretically possible, viral loads are detected on the screens.
“The most practical advice is for people to make sure they are thoroughly washing and cleaning their hands several times a day, thus reducing the risks of transmission of any infection.”
Public Health England (PHE) also told The Independent they are not issuing any guidance particularly around the use of touchscreens.
Instead people should continue to wash their hands frequently with hot water and soap for 20 seconds or use alcohol hand gel and be aware of safe coughing etiquette.
Should we use wipes on the touchscreens?
If you’re worried about using the screen and not having access to hand washing straight away then it could be tempting to use screen wipes (as people have been recommended to do with their individual mobile devices) but Michael Head says this isn’t a good idea.
Head says: “It’s probably not advisable to use wipes first on the screen, since the wipe may not adequately disinfect the screen, and it may also cause problems on the screen itself.
“So washing hands soon afterwards is definitely the best solution.”
Are shops and restaurants doing anything to make touchscreens safer?
Most supermarkets now have self-checkouts that require customers to interact with a touchscreen.
In the UK the British Retail Consortium – which represents major supermarkets – said stores are not going to stop using touchscreens but are increasing the number of deep cleans and are advising customers to take precautions.
Andrew Opie, director of food and sustainability at the BRC told The Independent: “Retailers are continuing to adhere to high standards of hygiene in store and are taking extra precautions as advised by PHE.
"Alongside this, we are urging everyone to follow Public Health England’s advice: wash hands frequently with hot water and soap for 20 seconds or use alcohol hand gel, and be aware of safe coughing etiquette.”
If you are experiencing coronavirus symptoms and recently travelled to a high-risk country, contact the NHS 111 helpline, stay at home and avoid close contact with other people.
