O’Neil said the town learned from Dragon Mosquito Control on Sept. 21 that a mosquito species known to carry EEE was found in traps. Testing proved they did not carry the virus, but on Sept. 24 precautionary spraying was scheduled for Sept. 28.
“All of this is being proactive,” he said.
The infected mosquitoes were found Sept. 27, but rain forced the postponement of spraying until Tuesday, O’Neil said. The state never announced its positive finding.
Metzler said yesterday he will consult with the town further, possibly this weekend, to see if any other measures should be taken to minimize the threat.
Danville is among several Southern New Hampshire towns where mosquitoes with EEE have been found. The others include Newton, Sandown and Derry, where a horse with the virus died two weeks ago. Mosquitoes with the West Nile virus have been trapped in Salem.
A 20-year-old Newton woman contracted EEE in 2005 and died. Another Newton resident, an unidentified man, was infected with EEE in 2007 but recovered.
In Massachusetts, an Amesbury woman with EEE died Sept. 24 and a Georgetown man with the virus died Sept. 27.
Communities, including Haverhill, are taking precautions such as restricting outdoor activities. A Haverhill High School football game was rescheduled from last night to today because of EEE.
