Had a consult with the 'travel doctor' prior to an up-coming trip. Asked him about this virus.
He said I was too early to say too much, but he likened it to the SARS outbreak as far as morbidity was concerned. Advised re type of mask to be worn at airports (I'm not going to China, but Taiwan and Japan, which in 6 weeks time will be close enough!! let alone anywhere else). Noted that air planes are not a great risk, except the people immediately behind and in front of you and that transmission via surfaces probably a bigger risk (again, at current level of knowledge). Airports dodgy, but he doesn't have much faith in the temperature detection units, having observed one in action once.
I asked if a flu shot would be of any help - he said it would help against the flu, which is still a much bigger killer than the Corona virus!! But stocks are now out of date, so can't get one if I wanted it.
