Not necessarily for a number of reasons. China only confirmed human to human transmission was possible on 21st January, prior to that it wouldn’t really have been on anyone’s radar not even the WHO. If everyone believed it was only transmittable from animals to humans then nobody outside or China would’ve been worried, that would represent virtually zero threat to us. Yet in reality it was spreading like wild fire in China at the latest from December onwards. We had no travel bans from China until mid February yet the Xmas New year period is when people move around the globe in huge numbers. So in the UK in January or even December would a death from something that seemed like pneumonia in an elderly or already ill patient have been picked up?
