What is considered to be a high fever in adults?

My son is running a temperature and I'm not sure if it's high enough to worry about. At what temperature do we consider it a 'high fever' for an adult? I want to know for myself too, just in case.

In adults, any temperature above 103°F (39.4°C) is considered a high-grade fever. If it reaches this point or doesn't come down with basic paracetamol, you should consult a doctor to find the source of infection.

According to my family doctor, while 100.4°F is a mild fever, anything crossing 103°F is considered a high fever in adults. He advised that we must seek medical attention if it stays at 103°F or higher for more than three days.

If the thermometer says 103°F, your body is basically acting like a microwave. That is definitely a high fever, so stop trying to be a superhero and go see a doctor!

Actually yaar, once it crosses 103°F, it's a high fever and things get serious. Don't just sit at home trying cold compresses forever, go visit your doctor to get the right treatment.

I totally get how scary it feels when your body is burning up. A temperature of 103°F or more is considered a high fever, so please take plenty of rest and don't hesitate to reach out to a doctor.

A high fever in adults is 103°F and above. If you hit this temperature, don't delay or self-medicate blindly; visit a proper clinic and get a diagnosis immediately.

When my sister had a fever of 103°F last month, we were so worried. That is considered a high fever, so make sure you stay hydrated and contact a doctor if it doesn't budge.
