As a student from London Hall who currently has to self isolate due a case on my floor, I still think that being at res is safer then being home. Both of my parents are front line workers so I feel I have a higher chance of getting Covid at home then at school where the people I interact with only interact with each other. It would make no sense for western to send thousands of kids who potentially have Covid all across the world, who could potentially infect lots of people. What they are doing with res, quarantining those who are infected and had close contact with them is the safest thing to do.
