Seven people may have brought Covid-19 into NI, experts say

Seven people who were exposed to Covid-19 but had neither symptoms nor were infectious may have brought the virus into Northern Ireland on 1 March 2020. Researchers at Queen's University Belfast suggest it took about 9.6 days for someone exposed to Covid to develop symptoms and become infectious. They said a symptomatic patient could spread the disease for nine days. Experts from the school of mathematics and physics used modelling to reach their conclusions. Dr Gabor Kiss, who led the research, said the number seven was significant because while this seems a small number, the consequences demonstrate 'just how infectious Covid-19 is'.
