Some Wilton residents have questioned if contact tracing of COVID-19 exposure is mandatory, and what happens to the information provided.  First Selectman Lynne Vanderslice says participation is voluntary, and performed by the Wilton Health Department.  School nurses are currently assisting in the efforts.  Information is confidential and protected by HIPPA laws.  If direct contacts are provided by the positive resident, those individuals are contacted and told they may have been exposed and advised. The information remains with Wilton’s Health Department.  There is no universal computer-based system used by municipalities to facilitate contact tracing. The State engaged Microsoft to develop the system.  That system is currently being tested by 20 municipalities.  Wilton is not one of these municipalities.
