My Child Has a Fever: Urgent Care, or ER?

Written By Dr. Terry Matthews

Your child feels warm, the thermometer confirms a fever, and suddenly you are deciding what to do next. Can this wait? Should you head to urgent care? Is the emergency room the safer choice?

For many childhood illnesses, Lansing Urgent Care is a convenient place to get an examination, answers, and a treatment plan. If your child is alert, breathing comfortably, drinking fluids, and has no emergency warning signs, our team can help you understand what is causing the fever and what to do next.

Here in Michigan, we are in respiratory season—a time when families encounter COVID-19, flu, and RSV, alongside other infections such as strep throat. These illnesses can cause similar symptoms, making it difficult to know what your child has based on a fever alone.

When Lansing Urgent Care Is a Good Choice

A fever with a sore throat, cough, congestion, body aches, or ear pain is often appropriate for evaluation at Lansing Urgent Care when your child is otherwise stable. We care for children ages 3 months and older and offer testing for COVID-19, flu, RSV, and strep when medically appropriate.

Consider bringing your child in when:

• A fever comes with a sore throat, ear pain, cough, or other uncomfortable symptoms.
• Symptoms are worsening or your child is not improving as expected.
• You are concerned about a possible flu, COVID-19, RSV, or strep infection.
• You are unsure what is causing the illness or how to care for your child at home.
  
  

You do not have to wait for symptoms to become severe before seeking help. An evaluation can provide a clearer picture of your child’s illness and a plan for treatment, comfort, and follow-up.

Some treatments are time-sensitive. For example, flu antiviral medicines work best when started within the first two days of symptoms, although some children benefit from treatment later. Early evaluation is especially helpful for young children and those with conditions that increase their risk of complications.

Look Beyond the Thermometer

A fever is generally a temperature of 100.4°F or higher. It is a sign that the body is responding to an illness, but the number alone does not tell you how serious that illness is.

Pay attention to your child’s breathing, alertness, fluid intake, and urination. A child who is interacting with you and taking fluids is different from a child who is difficult to wake, struggling to breathe, or becoming dehydrated. A lower fever can still accompany a serious illness, and improvement after fever medicine does not rule one out.

For babies ages 3 to 6 months, contact a clinician promptly about a fever rather than waiting several days. Children with weakened immune systems or serious underlying conditions also need prompt, individualized guidance.

When to Choose the Emergency Room

Some symptoms need the resources of a hospital emergency department. Go to the ER for:

• Altered consciousness: confusion, difficulty waking, unusual unresponsiveness, or a child who is not interacting normally.
• Significant dehydration: very little urine or no urine for about eight hours, a very dry mouth, absent tears, or marked weakness—especially when your child cannot drink.
• Recurrent vomiting or frequent diarrhea with inability to keep fluids down, worsening weakness, or signs of dehydration. Bloody vomit or stool, green vomit, or severe abdominal pain also warrants emergency evaluation.
• Breathing difficulty: struggling for air, skin pulling in around the ribs, or breathing problems that interfere with drinking or speaking.
• Fever with a stiff neck, severe headache, or a purple rash that does not fade when pressed.
  
  

High fevers also deserve prompt attention. A temperature repeatedly above 104°F requires immediate medical advice. Choose the ER if a high fever comes with any warning sign above or your child looks very ill. For a temperature around 105°F or higher, seek emergency evaluation rather than waiting for a routine visit.

A baby younger than 3 months with a temperature of 100.4°F or higher needs immediate medical evaluation, even if they otherwise seem well. Contact their pediatrician immediately; if you cannot obtain immediate guidance and evaluation, go to the ER. Lansing Urgent Care’s minimum patient age is 3 months.

Call 911 if your child is unresponsive, has severe trouble breathing, has blue or gray lips, or is having a seizure. Do not wait for an urgent care visit when emergency warning signs are present.

What to Expect at Lansing Urgent Care

Our providers will review your child’s symptoms, examine them, and determine whether testing is needed. Not every fever requires every test, and antibiotics are appropriate only for certain bacterial infections—not for viruses such as flu, COVID-19, or RSV.

You will receive guidance about treatment, keeping your child comfortable and hydrated, and which changes should prompt another visit or emergency care. If your child needs a higher level of care, our team will direct you appropriately.
