This year began with a dramatic increase in cases, placing additional pressure on state leaders and public health authorities around the country using traditional methods of contact tracing to help control the spread. Consumer technology like EN can support and augment these efforts. More than 20 states around the country are currently using EN to send alerts to users who have been exposed to COVID-19, while helping to protect their privacy, in order to dramatically reduce the time between a person's COVID exposure, a test and isolation or treatment.
