Yesterday I posted a report from a teacher in Hangzhou who, along with other foreigners on the staff, was being called in for special health checks as part of anti-flu precautions. The teacher wondered whether this was a Hangzhou localism or a wider policy.
Since then I have received no reports of special health checks for foreigners, and many comments to the effect that "all is routine here." So it appears to be a one-city or even one-school policy. Worth noting.
Update: Have heard from one teacher in Suzhou about health checks there too (not far from Hangzhou, so maybe....) and an expat in Beijing about getting temperature checked on the way into his apartment building gym. Adding: "(lucky they didn't take it one the way out. Would have been quarantined for sure. Or perhaps shipped out to a morgue)."
