Fever tracking guide
- Does your child have a fever?
- Are you experiencing flu symptoms?
- Do you remember when your fever or symptoms started?
- When was your last dose of medication and what was your body temperature?
A fever tracker app like CareClinic can help you monitor your symptoms and track your medications, and share what you tracked with your doctor or family members.
What is a fever?
Fever or pyrexia is when you have a temperature that is above the normal range or the body's set point.
A normal body temperature is about 36.1 to 37.2 °C (97 to 99 °F).
- Set point risesYour muscles contract and you feel cold.
- Heat buildsYour body makes more heat and works to keep it.
- Set point returnsYou feel hot, look flushed and may begin to sweat.
Young children may also experience a febrile seizure but this is very rare.
What causes a fever?
A fever can be caused by a variety of medical conditions which can be non-serious or life-threatening.
Infections
Viruses, bacteria or parasites.
- Influenza
- Meningitis
- UTIs
- Appendicitis
- Malaria
Inflammation and other causes
Vasculitis, when blood vessels become inflamed, and other non-infectious causes.
- Vasculitis
- Deep vein thrombosis (DVT)
- Connective tissue disease
- Cancer
How fevers work
Body temperature is regulated by the hypothalamus in the brain. A pyrogen triggers the release of prostaglandin E2 (PGE2), which raises your temperature and set point.
Narrowed blood vessels and shivering hold in heat. When the hypothalamic set point moves back to baseline, sweating and vasodilation cool the body. A faster heart rate can raise blood pressure during a fever.
Types of fever
Different types of fever can indicate the potential cause behind the fever and lead to a diagnosis.
Continuous fever
Stays above normal all day and moves less than 1 °C in 24 hours. May indicate pneumonia, typhoid, meningitis or a UTI.
Intermittent fever
Rises above the set point for a while, then returns to normal. May indicate malaria, leishmaniasis or sepsis.
Remittent fever
Stays above normal all day and moves more than 1 °C in 24 hours. Can indicate infective endocarditis or brucellosis.
- MalariaMalaria can cause quotidian fever, tertian fever and quartan fever.
- Neutropenic feverOccurs when the immune system is not working normally, often during chemotherapy. It is a medical emergency.
- Fever of unknown originA persistent fever that repeated routine clinical inquiries cannot explain.
Why track a fever?
A fever can point to a serious underlying issue, so know when to see a doctor.
A fever of unknown origin is a greater concern in infants and children. Talk to your doctor if your child has a cold or diarrhea with a fever, or is:
- 01
Younger than 3 months and has a rectal temperature of 100.4 F (38 C) or higher.
- 02
Between ages 3 and 6 months and has a rectal temperature up to 102 F (38.9 C) and seems unusually irritable or uncomfortable
- 03
Between ages 6 months and 2 years old and has a rectal temperature higher than 102 F (38.9 C) that lasts longer than one day but shows no other symptoms.
Common adult fever symptoms are the following:
- headache
- warm forehead
- chills
- aching muscles
- a general feeling of weakness
- sore eyes
- loss of appetite
- dehydration
- swollen lymph nodes
Many hospitals advised tracking symptoms at home during Covid-19.
Treating a fever
A fever is usually your body defending itself against infection. Depending on your age, condition and the cause, you may or may not need medical treatment.
Treatments vary with the cause. Antibiotics treat bacterial infections, and the most common options are over-the-counter drugs like acetaminophen and NSAIDs.
If you are experiencing a fever, it is important to do the following:
- Drink a lot of clear liquids such as water, broth, and juices.
- Take a lukewarm bath.
- Rest and stay home.
- Keep yourself cool with lightweight clothing and bed coverings.

CareClinic, a free fever tracker app
CareClinic starts with a care plan of your medications, natural remedies and other health routines, then helps you stick to it and track symptoms, including fever.
- Add as many medications and supplements as needed.
- Get notified if there are interactions* or synergies.
- Add medications, activities and nutrition to your care plan, with quick reminders.
- Connect wearables that sync with Apple Health or Health Connect.

- Get periodic reminders for refills, and or from your care team.
- Log any one-time medications (PRNs) as needed.
- View reports and correlations by yourself and share them with your care provider.
Use the diary to record symptoms, mood, thoughts and body temperature, so your healthcare provider can refer to them during and after appointments.
Manage symptoms
Use the app as your digital health diary. Track fever with headaches, fatigue, mood, anxiety, migraines, insomnia and more, plus sleep, energy and weight.
- Log it
Pick symptoms from a list, add a start and end date, and note changes like "the fever has gone down to 101°F."
- See it
View symptoms in Charts or Log format, and use correlation reports to spot links with food, allergies or other factors.
- Share it
Send reports to your CareTeam or print them for your doctor's appointment, on mobile or the web.
Use it as a pill reminder
Search for your medication, pick the exact type, color, size and dosage, or upload a photo of it. Branded and generic versions are both there.
Set daily, weekly or hourly reminders, and record side effects, purpose and effectiveness. On iOS, say "Check In to Medication" to Siri to open CareClinic.
Keep a health diary
Journaling in a mobile app is quick, with no laptop or pad and paper. Track fever symptoms, mood and thoughts for women's health, kids' health or seniors' health.
Instead of printed templates, CareClinic uses Care Plans, and your check-ins become structured reports.
Track your vitals
Log measurements such as breath frequency and resting heart rate. Fighting a fever can make your heart work harder and raise your blood pressure, so track these if you have heart or blood pressure problems.
With a Bluetooth thermometer, import your temperature into Apple Health and CareClinic pulls the values in.
Measure, then log
CareClinic is a place to record temperature readings, not a tool that measures your temperature or diagnoses a fever. Take your temperature with a thermometer, then enter the reading in the app.
