What is a fever?

A fever is defined as a temporary increase in your body temperature, to levels greater than 38 degrees celsius or 100 degrees fahrenheit. Fevers are most often due to an infection, and are part of your body’s natural defence systems kicking in.

A fever is triggered when the hypothalamus (the section of the brain that controls body temperature) increase the body’s temperature. Infections (like a cold or sinus infection) typically induce a fever, but fevers can also be caused by conditions other than infections.

Common causes of a fever include:

  • Bacterial infections
  • Cancer
  • Conditions that cause inflammation
  • Ear, lung, skin, throat, bladder, or kidney infections
  • Gastroenteritis (inflammation of the stomach or intestines resulting from a bacterial or viral infection)
  • Heat exhaustion
  • Side effects of drugs
  • Vaccines
  • Viruses

Less common causes of a fever include:

  • Autoimmune diseases
  • Blood clots
  • Hormone disorders
  • Illegal drugs like amphetamines and cocaine
What are the symptoms of a fever?
  • Chills and shivering
  • Dehydration
  • General weakness
  • Headache
  • Irritability
  • Loss of appetite
  • Muscle aches
  • Sweating

Treatment for a fever depends on the cause. Consult with a physician on the best treatment option for you.

Common treatment options include taking over the counter drugs such as Acetaminophen (Tylenol),  Aleve – Naproxen or Ibuprofen (Advil, Motrin, etc.).

When should I see a doctor about a fever?

Fevers in adults usually go away on their own, and don’t typically require urgent medical attention.

You should see a doctor if:

  • Your body temperature is 39°C or above
  • You have a severe headache
  • You have unusual sensitivity to bright light
  • You have a stiff neck or pain when you tuck your chin to your chest
  • You experience mental confusion
  • You are persistently vomiting
  • You have chest pain or difficulty breathing
  • You get abdominal pain or pain when urinating
  • You experience convulsions or seizures
What should I do if my infant or child has a fever?

Children between the age of 6 months and 5 years are at risk for experiencing seizures as a result of a fever. You should see a doctor right away if your child has a fever above 39°C or if your child experiences any seizure activity with their fever.

Fever is an emergency in infants under the age of three months. For this age group, you should proceed to the ER for any temperature above 38°C. 

Get in touch with a doctor if:

  • Your child is younger than age 2 and has a fever that lasts longer than a day
  • Your child is older than 2 and has a fever lasting longer than 3 days

You should also seek medical attention if your child’s fever is accompanied by:

  • Cough
  • Diarrhea
  • Ear Pain
  • Fussiness
  • Lethargy
  • Poor appetite
  • Sore throat
  • Vomiting

What is Maple?

Our doctors can assess symptoms, and provide treatment, including prescriptions as necessary.

You can visit our How it Works page to learn more.

Can a doctor treat fever on Maple?

In most cases, a Maple doctor can diagnose you or your child’s fever online by asking about symptoms, conditions, medication consumed, and/or if you or your child recently travelled to an area that poses a high infection.

Once you describe your symptoms and answer the doctor’s questions, they may then examine you or your child over video. In many cases, they will be able to diagnose and prescribe appropriate medication. 

If the doctor suspects you or your child have a more serious problem, they may suggest you go to a clinic for a thorough in-person physical examination.

Can I get a prescription on Maple?

Yes, our physicians can prescribe medications online during your consultation. Once you accept a prescription, you’ll have the option to pick it up from any pharmacy or we’ll deliver it right to your door at no additional cost.

Not having to endure a long wait at a walk in clinic is fabulous. Especially since I have twin pre-schoolers to contend with.

The service is so quick and professional and saves hours spent in a walk-in-clinic. This is a game changer for busy moms and I recommend it to everyone!

Instead of my husband having to drag both kids to the hospital or walk in alone he was able to see a doctor right away and get a prescription faxed to our local pharmacy.

Our family has used this service twice so far and it has been amazing. Both doctors were friendly, compassionate and you never feel rushed.
