LONDON (Reuters) -England's COVID-19 mobile phone app will be tweaked so that fewer contacts of asymptomatic people who test positive for the disease will need to self-isolate, Britain's health ministry said on Monday.
Business leaders have raised concerns about the numbers of staff who are having to self-isolate after being "pinged" by the app when they come into contact with someone who then tests positive for COVID-19.
