UNDERGRADUATE STUDENTS in 🇬🇧 and #COVID19 antibody prevalence—UK govt study at 5 universities, 2900+ students tested: younger students aged 17-19 more likely positive than older (aOR 3.2), living in halls of residence (aOR 2.1), and sharing a kitchen. 🧵

2) And among students living in dormitories (halls of residence), males had higher odds of positive antibodies, along with again age 17-19, larger dorm population, and more people sharing the kitchen.

3) Overall, SARS-CoV-2 seroprevalence in 2,905 university students was 17.8% (95%CI, 16.5-19.3), ranging between 7.6%-29.7% across the five universities.

4) Seropositivity was 49% in students living in halls of residence that reported high SARS-CoV-2 infection rates (>8%) during the autumn term.

5) Interpretation: “Despite large numbers of cases and outbreaks in universities, less than one in five students (17.8%) overall had SARS-CoV-2 antibodies at the end of the autumn term in 🏴󠁧󠁢󠁥󠁮󠁧󠁿.

6) “In university halls of residence affected by a COVID-19 outbreak, however, nearly half the resident students became infected and developed SARS-CoV-2 antibodies.”
