Former Exeter Hospital patients from Raymond, Kingston, Exeter and Newmarket filed lawsuits blaming the hospital for infecting them with the potentially deadly hepatitis C virus, their attorney said Tuesday. The suits, filed by three married patients and their spouses and a fourth unmarried patient, accuse the hospital of negligence, reckless conduct and intentional infliction of emotional distress. They also blame the hospital for violating the state Consumer Protection Act and, in the case of married patients, loss of consortium with their spouses. All seek a jury trial.
