Working as a contact tracer can be a rewarding career for those who enjoy interacting with the public and helping a community eradicate contagious diseases. Contact tracing became a familiar term during the COVID-19 pandemic, but it has been around since the 1920s, and opportunities aren’t limited to global viruses. 

Contact tracers are essential to public health as they work during contagious disease outbreaks to identify those who may have been exposed to an infection or virus. The contract tracer notifies anyone who has had contact with an infected person and works to mitigate the further spread of the disease. COVID tracking has resulted in hiring tens of thousands of contact tracers. This article explains more about the role and how you can earn a certificate and work in the field of contact tracing.

What is contract tracing? 

The purpose of contract tracing is to identify people who have been exposed to a communicable disease so those they may have been in close contact with can be notified. Contract tracing helps contain the spread of infectious diseases by quarantining those who are ill and those who may have been exposed to a sick person.

Contract tracers deploy when transmissible diseases such as measles, tuberculosis, hepatitis, sexually transmitted diseases, and HIV are found in a community. 

What does a contact tracer do?

In your role as a contact tracer, you’ll reach out to someone with confirmed communicable diseases. You will ask a series of questions to determine where the person recently traveled, who they had contact with, and if they had been at any public settings such as schools, work, or large gatherings.

You’ll note anyone the person may have been in close contact with, so those people can be notified and advised on what to do next.

Responsibilities of a contact tracer 

As a contact tracer, you’ll be responsible for maintaining the confidentiality of the patient and anyone exposed to the patient. You’ll be required to communicate with patients and medical professionals.

You may also be responsible for making follow-up calls to check on patients and provide referrals if needed.

A contact tracer is responsible for keeping patient records of symptoms and living arrangements and noting any underlying medical conditions. You may also research social media accounts, GPS data, and other databases to find out where a person has been.

Key skills

Most contact tracing positions don’t require a specialized background, but it is helpful to have an interest in public health. You’ll need strong communication and persuasive skills, empathy, and good listening skills. You also benefit from persistence, organization, and critical thinking skills.  

You should be comfortable speaking with patients who may be scared, confused, or aggressive, and you’ll work with a diverse population. You’ll also need to be comfortable contacting those who may have been exposed to a communicable disease and ready to answer questions.

An essential part of the job is ensuring patients understand the importance of self-quarantining and have the resources needed to get through the quarantine period. Some people might be reluctant to follow quarantine orders because they fear losing their income or their living arrangements make it difficult or impossible to stay away from others in their household.

Much of the job will be making telephone calls or contacting patients by email, and you may have large volumes of calls each day. Most contact tracers work from home and input the information into a database. You may be required to sit for long periods.

Becoming a contact tracer 

The minimum educational requirement is generally a high school diploma. You can prepare to be a contact tracer in as little as seven hours. John Hopkins University offers a COVID-19 Contact Tracing online course on Coursera to earn a sharable certificate in contact tracing. You can work at your own pace and learn all you need to begin a new career helping others.
