Hmm, that paper references another paper for its >50% infected claim but the paper it references only has a 24% seropositivity rate. It does suggest 53.5% infection but that’s based on a naive SIR model which I don’t expect to give particularly accurate results for that kind of thing.
Good to see a detailed examination of reinfections though—that’s the kind of thing I’ve been hoping to see.
Another, more recent, paper does find 66% seropositivity in migrant workers (who make up 60% of the population). However the sample seems to have been selected strongly for people who had had Covid as 20% of the sample had already had positive PCR results, compared to ~4% of the total population.

User Annapurna posted a webpage that tracks Covid-19 reinfections, in case you hadn’t seen it.
