Chincoteague lost four more ponies to the mysterious disease known as swamp cancer.
Officials on Friday announced on Facebook that they had been euthanized marking a long battle with the panful disease.
The Salisbury Daily Times reports that brings the total number up to seven over the last few months.
Denise Bowden with the Chincoteague Volunteer Fire Company said on Facebook that there were surgeries and more medicine than one can image along with round-the-clock care.
But, she said, it was to no avail.
The disease can be contracted through cuts or holes from mosquito bites.
The fungus-like disease produces lesions on the ponies’ bodies.
