Common Signs and Symptoms of Viral Meningitis

When a severe headache strikes alongside a high fever, most people assume it’s just the flu — but these could be warning signs of something far more serious, like meningitis. Viral meningitis, an inflammation of the protective membranes surrounding your brain and spinal cord, requires immediate medical attention. 

Here are the key signs and symptoms of viral meningitis to watch for:

General symptoms:

• High fever that develops suddenly
• Severe headache that feels different from typical headaches
• Stiff neck that makes it difficult or painful to touch chin to chest
• Nausea and vomiting
• Fatigue and extreme weakness
• Loss of appetite
• Sensitivity to bright light (photophobia)

Neurological symptoms:

• Confusion or difficulty concentrating
• Drowsiness or difficulty staying awake
• Seizures in severe cases
• Difficulty walking or maintaining balance

Symptoms in infants and young children:

• Constant crying or irritability
• Excessive sleepiness or difficulty waking
• Poor feeding or refusal to eat
• Bulging soft spot (fontanel) on top of the head
• Stiffness in the body or neck

If you or a loved one experiences any combination of these symptoms, don’t wait — visit your nearest Complete Care ER location immediately. Our emergency-trained doctors are available 24/7 to provide rapid diagnosis and treatment for viral meningitis, ensuring you receive the urgent care you need without the long wait times of traditional hospital emergency rooms.

For life-threatening situations, please call 911.

What causes meningitis?

Viral meningitis happens when a virus attacks the protective layers that wrap around your brain and spinal cord. Think of these layers like a cushion that keeps your brain safe — when they get inflamed, that’s meningitis. The viruses that most often cause this are called enteroviruses, and they’re especially common during the summer and fall. Other viruses like herpes, mumps, West Nile, and even severe cases of the cold and flu can also trigger meningitis.

So how do you catch it? These viruses spread the same way a cold does — through coughs and sneezes, touching an infected person, or touching surfaces they’ve contaminated. Once the virus gets into your body, it can travel through your bloodstream and reach those protective layers around your brain, causing them to swell up. 

Here’s the good news: most people who get exposed to these viruses only feel a little under the weather, or don’t get sick at all. But sometimes the infection does develop into meningitis, which is why knowing what to watch for is so important.

Different types of meningitis

While we’ve been focusing on viral meningitis, it’s important to understand that meningitis comes in several forms, each caused by different germs and varying in severity. Knowing the differences can help you understand why quick medical attention is so crucial — some types are more dangerous than others and require different treatments.

• Viral meningitis: The most common and typically least severe form, usually resolving on its own with supportive care
• Bacterial meningitis: A medical emergency that can be life-threatening and requires immediate antibiotic treatment
• Fungal meningitis: Rare and typically affects people with weakened immune systems
• Parasitic meningitis: Very rare and usually contracted through contaminated water sources

The challenge is that all types of meningitis can start with similar symptoms, making it nearly impossible to tell them apart without proper medical testing. That’s why any suspected case of meningitis should be treated as a potential emergency. Only healthcare professionals can run the necessary tests — like a spinal tap or blood work — to determine which type you’re dealing with and provide the right treatment quickly.

General symptoms of viral meningitis

What is usually the first symptom of meningitis? Most people first notice a sudden high fever accompanied by an intense headache that feels different from typical headaches and migraines. These early-stage meningitis symptoms often appear within three to seven days after exposure to the virus and can easily be mistaken for the flu. 

However, unlike a regular illness, viral meningitis symptoms tend to come on quickly and intensify rapidly, making it essential to pay attention to what your body is telling you. Here’s what to keep an eye on: 

• High fever: Develops suddenly and often reaches 100.4°F or higher, making you feel immediately unwell rather than gradually getting sick over several days.
• Severe headache: Feels different from typical headaches — this one is often described as the worst headache of your life and doesn’t respond well to over-the-counter pain relievers.
• Stiff neck: Makes it difficult or painful to touch your chin to your chest, and you may find it hard to move your head forward or look down.
• Nausea and vomiting: Can be persistent and severe, often making it difficult to keep food or liquids down.
• Fatigue and extreme weakness: Goes beyond normal tiredness, leaving you feeling completely drained and unable to perform everyday activities.
• Loss of appetite: You may have no desire to eat, and the thought of food might make nausea worse.
• Sensitivity to bright light: You may find yourself wanting to stay in a dark room because lights feel painfully bright and make your headache worse.
• Meningitis rash: Though more common with bacterial meningitis, some viral cases may show skin changes or a rash that doesn’t fade when pressed.

If you’re experiencing several of these symptoms together — especially the classic trio of fever, headache, and stiff neck — don’t brush them off as just another bug going around. These warning signs warrant immediate medical evaluation to rule out meningitis and begin appropriate care.

Neurological symptoms of viral meningitis

As viral meningitis progresses, the inflammation around your brain can begin to affect how your nervous system functions. These neurological symptoms indicate that the infection is impacting your brain more seriously and requires urgent medical attention.

Neurological symptoms to look out for:

• Confusion or difficulty concentrating: You may have trouble thinking clearly, following conversations, or remembering simple things you normally wouldn’t forget.
• Drowsiness or difficulty staying awake: Extreme sleepiness that goes beyond normal fatigue, where you struggle to keep your eyes open or keep drifting off even when trying to stay alert.
• Disorientation: Not knowing where you are, what day it is, or having difficulty recognizing familiar people or places.
• Difficulty walking or maintaining balance: Problems with coordination, stumbling, or feeling unsteady on your feet when you try to move around.
• Seizures: In more severe cases, you may experience convulsions or sudden, uncontrolled muscle movements that require immediate emergency care.

These symptoms mean the virus is affecting your brain function, and you shouldn’t wait to see if they improve on their own. Neurological changes require immediate evaluation by medical professionals who can assess the severity of your condition and provide the necessary treatment to prevent complications.

Viral meningitis symptoms in infants and young children

Unlike older children and adults who can describe their headache or neck stiffness, infants show different warning signs that parents and caregivers need to watch for carefully. If your child is also experiencing symptoms similar to an RSV sore throat or other viral illness, pay extra attention to these additional red flags:

• Constant crying or irritability: Your baby may cry inconsolably with a high-pitched sound that’s different from their normal crying, and nothing you do seems to comfort them.
• Excessive sleepiness: Your child is unusually difficult to wake up, doesn’t respond to stimulation like they normally would, or seems less alert than usual.
• Poor feeding or refusal to eat: Your baby shows no interest in feeding, turns away from the bottle or breast, or is too lethargic to eat properly.
• Bulging soft spot: The fontanel (soft spot on top of the head) appears swollen or bulges outward, which indicates increased pressure around the brain.
• Body stiffness or limpness: Your child’s body may feel unusually stiff and rigid, or conversely, they may seem floppy and unable to hold their normal muscle tone.
• Fever with cold hands and feet: Despite running a fever, your baby’s extremities feel cold to the touch, which can indicate poor circulation.

Children’s symptoms can worsen rapidly, so trust your parental instincts — if something feels seriously wrong, it probably is. Complete Care offers specialized pediatric emergency care with doctors trained to quickly assess and treat children with suspected meningitis. Don’t wait until morning or try to get a regular doctor’s appointment; meningitis in children requires immediate emergency evaluation to ensure your child gets the care they need when every minute counts.

When to go to the ER for meningitis symptoms

Meningitis is not a “wait and see” condition. Because symptoms can worsen quickly and the differences between viral and bacterial meningitis can’t be determined without medical testing, any suspected case of meningitis requires immediate emergency care. 

You should go to the emergency room immediately if you or someone else experiences:

• The combination of high fever, severe headache, and stiff neck together
• Any neurological symptoms like confusion, seizures, or extreme drowsiness
• Symptoms that are rapidly getting worse
• A rash that doesn’t fade when you press a glass against it
• Severe symptoms in an infant or young child, especially inconsolable crying or a bulging soft spot
• Any meningitis symptoms in someone with a weakened immune system

Meningitis requires immediate evaluation, diagnostic testing, and treatment that only an emergency room can provide.
