Most fevers are the body fighting a common virus. What matters most is how sick the person looks and which symptoms come with the fever.
FEVER WARNING SIGNS

When Should You Go to the ER for a Fever?

Go to the ER for a fever with confusion, a severe headache or stiff neck, trouble breathing, chest pain, a new rash, persistent vomiting, severe weakness, or signs of dehydration. In adults, a fever of 103°F or higher that doesn’t come down with medication, or any fever lasting more than three days, also deserves evaluation.
Infants, older adults, pregnant women, and people with weakened immune systems—such as those receiving chemotherapy—should be evaluated sooner, because serious infections can progress quickly with few early signs.

When Should a Child With Fever Go to the ER?

Febrile Seizures

Some young children have a brief seizure when a fever rises quickly.
Febrile seizures usually last less than a few minutes and most often affect children between 6 months and 5 years old. They are frightening but usually not harmful, and a child should be evaluated after any first seizure. Call 911 for a seizure lasting longer than five minutes, trouble breathing, or a child who doesn’t wake up normally afterward. See our pediatric emergency care page.
CONCERNING COMBINATIONS

Fever With Other Symptoms That Need Attention

The symptoms that come with a fever often point to where an infection is and how serious it may be.
Fever with cough or shortness of breath may mean pneumonia; see our respiratory infection page. Fever with painful urination or back pain can signal a kidney infection; learn more about urinary tract infections.
Fever with vomiting or diarrhea raises the risk of dehydration; see vomiting and dehydration care. Fever with a red, warm, swollen area of skin may be cellulitis or an abscess, especially if the redness is spreading.
YOUR ER VISIT

What Happens When You Visit the ER for a Fever?

The physician checks your temperature, heart rate, breathing, oxygen level, and blood pressure, then looks for the source of the infection.

Lab & Infection Tests

Blood counts, cultures, urinalysis, and rapid tests for flu, COVID-19, or strep can help identify the cause.

Imaging

A chest X-ray or CT may be ordered if pneumonia, an abscess, or another hidden infection is suspected.

Treatment

Fever-reducing medication, IV fluids, and antibiotics may be given when the evaluation shows they’re needed.
Antibiotics treat bacterial infections, not viruses, so they aren’t prescribed for every fever. Testing is based on your symptoms and exam.

What Can Cause a High Fever?

Possible causes can include:

Viral Infections

Influenza, COVID-19, and other viruses are the most common causes of fever.

Respiratory Infections

Pneumonia, bronchitis, sinus infections, and strep throat.

Urinary & Kidney Infections

Bladder and kidney infections, which in older adults may cause fever with few urinary symptoms.

Skin & Other Causes

Cellulitis, abscesses, infected wounds, heat illness, and some medication reactions.

QUICK ANSWERS

Fever Questions, Answered

When should an adult go to the ER for a high fever?

An adult should go to the ER for a fever with confusion, a stiff neck, trouble breathing, chest pain, a new rash, persistent vomiting, severe weakness, or signs of dehydration. A fever of 103°F or higher that doesn’t come down with medication, or one lasting more than three days, also deserves evaluation—sooner if you have a weakened immune system.

Where should I go in Houston for fever, chills, and severe weakness?

Fever with chills and severe weakness can be an early sign of a serious infection, including sepsis, and should be evaluated in an emergency room. The Heights Emergency Room at 101 N Loop W #300 in Houston is open 24/7 with on-site lab testing, cultures, and imaging. Call 911 if the person is confused or struggling to breathe.

Is fever with dehydration an emergency?

It can be. Fever increases fluid loss, and vomiting or diarrhea make it worse. Dizziness, very little urine, a racing heart, or confusion suggest significant dehydration that needs emergency evaluation. Infants and older adults are especially vulnerable and should be seen promptly.

When can an infection become an ER emergency?

An infection becomes an emergency when it starts affecting the whole body or a vital organ—for example, sepsis, pneumonia with low oxygen, meningitis, or a kidney infection with vomiting. Warning signs include confusion, rapid breathing, a fast heart rate, severe pain, or redness that spreads quickly from a wound.

When should a child with fever go to the ER?

Take a child to the ER for any fever of 100.4°F or higher in a baby under 3 months, or a fever in a child who is hard to wake, breathing fast, dehydrated, has a rash that doesn’t fade when pressed, or has had a seizure. How the child looks and acts matters more than the number on the thermometer.
EMERGENCY SAFETY

When Should You Call 911 for a Fever?

Call 911 rather than driving if a fever comes with signs that the brain, breathing, or circulation is affected.

Call 911 for:

Paramedics can give oxygen, start IV fluids, and treat seizures on the way.
Don’t drive someone who is confused or having seizures; call 911 instead.
WHERE TO GO

ER vs Urgent Care for a Fever

Urgent care is often fine for a fever from a cold, flu, or sore throat when the person is otherwise doing well. When a fever comes with warning signs or affects someone at high risk, an emergency room offers the testing and treatment that may be needed.

FAQ

Fever ER — Frequently Asked Questions

In adults, a temperature of 100.4°F (38°C) or higher is a fever, and 103°F (39.4°C) or higher is generally considered high. In children, behavior and other symptoms matter as much as the number.

You can take acetaminophen or ibuprofen as directed if you’re able to, and tell the staff what you took and when. Don’t let a lower reading delay care if warning signs are present.

Fevers from infections rarely rise high enough to harm the brain. The bigger concern is the illness causing the fever. Very high body temperatures from heat stroke are different and are a medical emergency.

Only if a bacterial infection is found or strongly suspected. Most fevers are caused by viruses, which antibiotics don’t treat. Your physician decides based on your exam and test results.
