Abstract
BackgroundContact notification is a method used to control the spread of infectious disease. In this process, a patient who tests positive for an infectious disease and public health officials work to identify the patient’s close contacts, notify them of their risk of possible exposure to the disease, and provide resources to facilitate the decreased spreading of disease. Contact notification can be done physically in person, via phone call, or digitally through the use of media such as SMS text messages and email. When alerts are made through the latter, it is called digital contact notification.ObjectiveFor this study, we aim to perform a preliminary evaluation of the use of the TellYourContacts website, a digital contact notification tool for COVID-19 that can be used confidentially and anonymously. We will gather information about the number of website users and message senders, the types of messages sent, and the geographic distribution of senders.MethodsPatients who chose to get tested for COVID-19 and subsequently tested positive for the disease were alerted of their positive results through Curative Inc (a COVID-19 testing laboratory) and Healthvana (a results disclosure app). Included in the notification was a link to the TellYourContacts website and a message encouraging the person who tested positive for COVID-19 to use the website to alert their close contacts of exposure risk. Over the course of three months, from May 18, 2020, to August 17, 2020, we used Google Analytics and Microsoft Excel to record data on the number of website users and message senders, types of messages sent, and geographic distribution of the senders.ResultsOver the course of three months, 9130 users accessed the website and 1474 unique senders sent a total of 1957 messages, which included 1820 (93%) SMS text messages and 137 (7%) emails. Users sent messages from 40 US states, with the majority of US senders residing in California (49%).ConclusionsWe set out to determine if individuals who test positive for COVID-19 will use the TellYourContacts website to notify their close contacts of COVID-19 exposure risk. Our findings reveal that, during the observation period, each unique sender sent an average of 1.33 messages. The TellYourContacts website offers an additional method that individuals can and will use to notify their close contacts about a recent COVID-19 diagnosis.

Building Healthy Online Communities (BHOC) and Team Klausner Saving Lives (TKSL) collaborated to create and build the TellYourContacts website, which officially launched on May 13, 2020
We found that users chose to send SMS text messages over emails in a 13:1 ratio (1820 [93%] via SMS text messaging and 137 [7%] via email)
Summary
The process of contact tracing for COVID-19 varies, depending on the facility. the core concept includes first identifying those with an infection. Contact notification is a method used to control the spread of infectious disease In this process, a patient who tests positive for an infectious disease and public health officials work to identify the patient’s close contacts, notify them of their risk of possible exposure to the disease, and provide resources to facilitate the decreased spreading of disease.
