      Very interesting study out of Denmark looking at SARS-CoV-2 reinfections: - 0.65% symptomatic reinfections after 7 months - in sensitivity analysis this doubled to 1.2% - estimated ~80% short-term protection against reinfectionpic.twitter.com/iZHDpiISmI

      Studies like this make me very jealous of my Nordic colleagues. The authors had access to linked data for *the entire country of Denmark*, which is a pretty enormous strength of the researchpic.twitter.com/y2RXr5G2Js

      Basically, they looked at every PCR test done in the first wave, and followed up every person to see if they had tested positive in the first, second, or both waves Of those in the sample, 0.65% were infected twice

      The BIG caveat here is that this study (as with similar ones) relies on routine PCR tests, which means that the sample is selected for people who have a symptomatic infection

      While it was not statistically significant, it is interesting that the sensitivity analysis - which looked only at those who were regularly tested - found a higher incidence of reinfection than the main analysispic.twitter.com/tV8tN0BxW7

      That being said, it provides further quite strong evidence that in the short-term (7ish months) symptomatic reinfection is rare. Asymptomatic reinfection may be more common, it is still hard to say

          ELI5 (sorry for my ignorance), if 1.2% of people are re-infected, why is it closer to 80% effective not 98.8%? what basic error am i making... something to do with asymptomatic infection and 1.2% just is those confirmed..or? i doubt i am only one with this question. thanks!

          oh.. i think i found my error..something along lines of only 10% ish of general population was infected, so that why 1.2% being infected is closer to 80%..the 98.8% would only be if everyone had been infected once etc. that on the right track?

          Serious question : is there any known case where immunity from a virus would prevent someone from ever testing « positive » to a PCR test after being exposed again to the virus in the environment ?

          I wonder if this underestimates the degree of protection? I couldn't see adjustment for factors linked to greater chance of exposure during the second wave, such as occupation, crowded housing (including care home status) or PPE for the hospital cohort?
