Students returning home for Christmas caused thousands of Covid infections, study suggests
The IndependentThe return of university students to their homes over Christmas may have caused thousands of extra coronavirus infections, modelling suggests. Mathematicians at Cardiff University found that coronavirus-infected students returning home from university over the festive period would, on average, have infected approximately one other household member with the virus. Professor Paul Harper, who worked on the study, said: “With the potential movement of over 1 million UK students for the Christmas vacation, even a modest 1 per cent infection level would equate to 9,400 new secondary household cases across the country.” However, those infections could have led to many more Covid cases, the research team acknowledged, as the study did not consider transmission to the students’ wider home communities or include the impact of the journey home. The Department for Education said at the time that universities would be offered testing facilities to give students two lateral flow tests – which turn results around within the hour – three days apart. Jonathan Deeks, professor of biostatistics at the University of Birmingham, said researchers estimated that about 60 coronavirus cases were missed among students at the university who were tested before returning home for Christmas.
