The mother of one of the 30 people sickened by an outbreak of adenovirus at the Wanaque Center for Nursing and Rehabilitation has filed a lawsuit against the facility, alleging that it failed to take proper precautions to prevent the outbreak and failed to inform families.

The lawsuit was filed on Wednesday in Passaic County Superior Court on behalf of Paula Costigan and her son, William DelGrosso, 14, who has been hospitalized for weeks with the illness.
