I heard about this a year or so ago and it was discussed as the next bioweapon to be used in the US and elsewhere. Maybe India with its significant population is the testing ground.
1999-“This outbreak resulted in nearly 300 human cases and more than 100 deaths, and caused substantial economic impact as more than 1 million pigs were killed to help control the outbreak.”
Seems the rate should have been much higher with the reported mortality rate, especially in India????
