  • Description:
    Updated Nov. 5, 2020 Text Illness Monitoring, or TIM, is a text messaging system that helps public health organizations monitor symptoms of enrolled participants. Public health organizations can use this system at no cost to monitor symptoms consistent with COVID-19. Text Illness Monitoring (TIM) is a text messaging platform that helps monitor symptoms during an infectious disease outbreak. Public health officials have traditionally done symptom monitoring via telephone calls, which can be a time-consuming process requiring intensive resources. TIM allows for two-way short message service (SMS) text messaging to help public health organizations quickly identify enrolled participants reporting symptoms. TIM can be used to monitor an organization’s workforce or another specified population, such as contacts of an identified case. TIM is available at no cost and, at this time, is primarily intended for public health organizations at the federal, state, tribal, local, and territorial levels to assist with COVID-19 response activities.
