Unis have acted irresponsibly, basically forcing students into campus and into cramped accommodation. And then blaming the students when outbreaks occur.
Parties shouldn’t be happening, absolutely. But does anyone think that freshers won’t socialise, or party, or shag? Seriously? Health advice needs to be pragmatic or it won’t be effective. Shock horror, “students please don’t party” is not pragmatic advice.
Distance learning from home should have been the norm for all except the most practical or courses. And for those, unis should have ensured that accommodation was underbooked.
However, a uni is (amongst many things) a business; accommodation doubly so. So: get the students back, and blame them when the inevitable happens.
