Help us learn more about fevers

Join our temperature research study!

What do we know about fevers?

Fever is one of the most common signs of illness and causes anxiety to many. Doctors still struggle with determining the cause of a fever. In addition, "normal" and "febrile" temperatures vary between individuals.

Why this study?

Better understandings of how body temperature varies between individuals and identification of disease fever patterns (“feverprints”) could allow doctors to make faster, more accurate diagnoses.

How are we doing this study?

We seek to leverage modern technology to recruit thousands of children and adults from across the United States for the largest research study of body temperatures ever created. Join us!

What is the Feverprints app?

Who can participate?

Children and adults living in the United States who have access to an iPhone/iPod and a thermometer can enroll. Children under 18 years of age will need parental permission to participate.

You can learn more about this study on the FAQ page.

Adults and children of all ages can join this study.

Adults enrolling in the study will need to sign an electronic consent form. Children ages 7 to 17 years will need parental permission and sign an electronic assent form. Children ages 6 and under will need parental consent.

You can log your data manually and automatically.

You will be asked to record your temperature, medications, and symptoms on a regular basis. If you own a smart thermometer, we can import your temperature data automatically. We will provide you with a summary of your data that you can share with your doctors.

What will happen to my data?

How will my privacy be protected?

Your data will be sent to a secure database, and all of the information collected will be anonymous, meaning that the researchers won’t know who you are. Personal identity data like your name never leaves your phone.

Will there be any risks to my privacy?

Someone may be able to see your answers from your iPhone. Some of the data that you provide may be sensitive. For this reason, we never send your name, address, or birthday to our computers. You are only identified by a random number.

What my data will be used for?

Your anonymous data, along with that of other participants, will be analyzed together to improve our understanding of normal and abnormal temperatures, identify illnesses based on their “feverprints,” and evaluate the effect of fever medications on the underlying disease. Individual participants will never be identified.
