Early meningitis symptoms may mimic the flu (influenza). Symptoms may develop over several hours or over a few days.
Possible signs and symptoms in anyone older than the age of 2 include:
- Sudden high fever
- Stiff neck
- Severe headache that seems different than normal
- Headache with nausea or vomiting
- Confusion or difficulty concentrating
- Sleepiness or difficulty waking
- Sensitivity to light
- No appetite or thirst
- Skin rash (sometimes, such as in meningococcal meningitis)
Signs in newborns
Newborns and infants may show these signs:
- High fever
- Constant crying
- Excessive sleepiness or irritability
- Inactivity or sluggishness
- Poor feeding
- A bulge in the soft spot on top of a baby's head (fontanel)
- Stiffness in a baby's body and neck
Infants with meningitis may be difficult to comfort, and may even cry harder when held.
When to see a doctor
Seek immediate medical care if you or someone in your family has meningitis symptoms, such as:
- Severe, unrelenting headache
- Stiff neck
Bacterial meningitis is serious, and can be fatal within days without prompt antibiotic treatment. Delayed treatment increases the risk of permanent brain damage or death.
It's also important to talk to your doctor if a family member or someone you work with has meningitis. You may need to take medications to prevent getting the infection.
