Ingwavuma virus (ING), a Simbu group arbovirus, was isolated from a pool of Culex vishnui complex mosquitoes in the Chiangmai Valley, Thailand in 1970. ING neutralizing (N) antibody was found in 32% of pigs and 20% of dogs indigenous to the valley, but not in domestic fowl, cattle, or man. N antibody was also found in pigs from western, central and north-eastern Thailand. From 22 pigs lacking ING N antibody studied in central Thailand from March to June 1972, ING was isolated from the blood of 11 of the 16 with serologically confirmed infections. These findings extend the range of Ingwavuma virus eastward from Africa and India and define the important role of the domestic pig as a host of ING in Thailand.
