The earliest person to contract coronavirus within the UK has been identified, scientists believe.
Analysis of samples by the University of Nottingham showed a 75-year-old woman, from Nottinghamshire, tested positive on 21 February.
A Surrey resident was previously believed to have caught the virus first.
The woman is also understood to be first in the UK to die after contracting Covid-19.
News of the case has emerged only now, because samples were being analysed in retrospect by researchers as they investigated the origins of the UK pandemic.
