Chikungunya in Singapore: imported cases among travelers visiting friends and relatives.
Chikungunya infections were detected in Singapore among returning travelers who had visited friends and relatives (VFR) in India and Malaysia. These sporadic imported cases occurred over a year before the 2008 chikungunya outbreaks in Singapore, demonstrating the potential for introducing this emerging viral infection into new areas via VFR travel.
