Yes, I am an early bird and got my flu shot today. I also checked the Centers for Disease Control website to make sure I’m up to date with my recommended vaccinations for China. Of course, there are some nasty viruses and bugs out there for which there is no vaccine. Dengue fever is one of them, with no specific medicine that can cure it ! (map for the Eastern Hemisphere dengue fever areas from the CDC website). I travel to the green strip around Hong Kong. Seems the best one can do is to pack a thermometer and check in for medical care right away in case of fever.
