The planned aerial combat against eastern equine encephalitis in Bristol and Plymouth counties has been reported to be successfully carried, uncovered State officials. The whole spraying task to kill EEE virus was reportedly concluded Saturday night.

As per the state Department of Public Health’s plans, Acushnet and Rochester and parts of North Dartmouth, New Bedford, Fairhaven and Mattapoisett were to be sprayed with pesticide.

However, according to the state Department of Public Health website, those areas could witness another spray out. But no information relating the same has been extended, Jennifer Manley, a DPH spokeswoman posted Sunday.

The malignant virus called EEE is reported to have engulfed two horses in Massachusetts this summer, with this year witnessing the deadly virus on a high, the Department of Public Health highlights.

The recent reports have claimed six cases, tested positive for EEEE virus. The virus spreads by mosquitoes which eventually find its way in humans.

“We expect it to be effective in reducing a significant amount of the adult mosquitoes in the spray area”, DPH chief Joel Auerbach was quoted as saying. “The exact percentage of the population of adult mosquitoes is difficult to calculate”.

In addition, he outlined that the efforts would assist in eradicating more than 50% of the mosquito population.
