A day after federal prosecutors in Concord, N.H., charged David Matthew Kwiatkowski, state and federal investigators worked to determine whether the 32-year-old former Exeter Hospital employee, referred to by US Attorney John Kacavas as a “serial infector,” may have exposed other patients around the country to the virus, which can cause serious liver damage.
