Researchers with the Texas Department of State Health Services learned of an aerial vaccination program underway in Canada, and decided to try it in the equally vast south and west regions of Texas.
The results over the past 18 years have been dramatic, according to department spokesman Chris Van Deusen.
"Animal cases of the canine strain of rabies in southern Texas fell from 122 the year before the program began, to zero in 2000," Van Deusen said.
"There have only been two cases since then, and both of them were within a mile of the Rio Grande."
He said the program is also concentrated against the fox strain of rabies, and those cases have been reduced from 244 animal cases in 1995, to zero cases in the past two years.
"We have effectively eliminated these two strains of rabies from Texas," Van Deusen said, adding that there have been no human cases of rabies in the region since the airdrop began.
