概述
For most travelers to Asia, the risk for JE is very low but
varies based on destination, duration, season, and activities
(2). ACIP recommends JE vaccine for travelers who plan to
spend a month or longer in JE-endemic areas during the JE
virus transmission season. JE vaccine should be considered for
short-term travelers (<1 month) if they plan to travel outside
of an urban area and have an itinerary or activities that will
increase the risk of JE virus exposure. JE vaccine also is recommended
for laboratory personnel with a potential for exposure
to infectious JE virus (1).
