Meningitis is a rare infection that affects the delicate membranes called meninges that cover the brain and spinal cord. 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
- Seizures
- 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:
- Fever
- Severe, unrelenting headache
- Confusion
- Vomiting
- 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.
Causes
-
Meningitis
Viral infections are the most common cause of meningitis, followed by bacterial infections and, rarely, fungal infections. Because bacterial infections can be life-threatening, identifying the cause is essential.
Bacterial meningitis
Bacteria that enter the bloodstream and travel to the brain and spinal cord cause acute bacterial meningitis. But it can also occur when
bacteria directly invade the meninges. This may be caused by an ear or sinus infection, a skull fracture, or, rarely, after some surgeries.
Several strains of bacteria can cause acute bacterial meningitis, most commonly:
- Streptococcus pneumoniae (pneumococcus). This bacterium is the most common cause of bacterial meningitis in infants, young children and adults in the United States. It more commonly causes pneumonia or ear or sinus infections. A vaccine can help prevent this infection.
- Neisseria meningitidis (meningococcus). This bacterium is another leading cause of bacterial meningitis. These bacteria commonly cause an upper respiratory infection but can cause meningococcal meningitis when they enter the bloodstream. This is a highly contagious infection that affects mainly teenagers and young adults. It may cause local epidemics in college dormitories, boarding schools and military bases. A vaccine can help prevent infection.
- Haemophilus influenzae (haemophilus). Haemophilus influenzae type b (Hib) bacterium was once the leading cause of bacterial meningitis in children. But new Hib vaccines have greatly reduced the number of cases of this type of meningitis.
- Listeria monocytogenes (listeria). These bacteria can be found in unpasteurized cheeses, hot dogs and luncheon meats. Pregnant women, newborns, older adults and people with weakened immune systems are most susceptible. Listeria can cross the placental barrier, and infections in late pregnancy may be fatal to the baby.
Viral meningitis
Viral meningitis is usually mild and often clears on its own. Most cases in the United States are caused by a group of viruses known as
enteroviruses, which are most common in late summer and early fall. Viruses such as herpes simplex virus, HIV, mumps, West Nile virus and others also can cause viral meningitis.
Chronic meningitis
Slow-growing organisms (such as fungi and Mycobacterium tuberculosis) that invade the membranes and fluid surrounding your brain cause chronic meningitis. Chronic meningitis develops over two weeks or more. The symptoms of chronic meningitis — headaches, fever, vomiting and mental cloudiness — are similar to those of acute meningitis.
Fungal meningitis
Fungal meningitis is relatively uncommon and causes chronic meningitis. It may mimic acute bacterial meningitis. Fungal meningitis isn’t contagious from person to person. Cryptococcal meningitis is a common fungal form of the disease that affects people with immune deficiencies, such as AIDS. It’s life-threatening if not treated with an antifungal medication.
Other meningitis causes
Meningitis can also result from noninfectious causes, such as chemical reactions, drug allergies, some types of cancer and inflammatory diseases such as sarcoidosis.
Risk factors
Risk factors for meningitis include:
- Skipping vaccinations. Risk rises for anyone who hasn’t completed the recommended childhood or adult vaccination schedule.
- Age. Most cases of viral meningitis occur in children younger than age 5. Bacterial meningitis is common in those under age 20.
- Living in a community setting. College students living in dormitories, personnel on military bases, and children in boarding schools and child care facilities are at greater risk of meningococcal meningitis. This is probably because the bacterium is spread by the respiratory route, and spreads quickly through large groups.
- Pregnancy. Pregnancy increases the risk of listeriosis — an infection caused by listeria bacteria, which also may cause meningitis. Listeriosis increases the risk of miscarriage, stillbirth and premature delivery.
- Compromised immune system. AIDS, alcoholism, diabetes, use of immunosuppressant drugs and other factors that affect your immune system also make you more susceptible to meningitis. Having your spleen removed also increases your risk, and patients without a spleen should get vaccinated to minimize that risk.
Complications
Meningitis complications can be severe. The longer you or your child has the disease without treatment, the greater the risk of seizures and permanent neurological damage, including:
- Hearing loss
- Memory difficulty
- Learning disabilities
- Brain damage
- Gait problems
- Seizures
- Kidney failure
- Shock
- Death
With prompt treatment, even patients with severe meningitis can have good recovery.
Nicola, from Romford in Essex, had an excruciating headache that nothing would touch and knew something was seriously wrong. An ambulance was called and hospital doctors swiftly diagnosed viral meningitis. The 33-year-old mum tells her story here
“I woke up on Mothers’ Day with a terrible headache, thinking it was the start of a migraine. But this was different, the pain wouldn’t go, no matter the pain relief I took!”
“I tried to play it down as my children Ellie and Riley were trying to spoil me as it was Mothers’ Day but I just couldn’t move from my bed. I went to bed early that night and woke at 5am with the worst pain I have ever felt in my head. I instantly knew something was wrong and my husband Dale called for an ambulance.”
“By the time the ambulance had arrived the pain was unbearable. I collapsed in my mum’s arms and then started being violently sick once I came around. My neck was stiff and I had pain going down my back.”
Pain was unbearable
“My husband and mum had to carry me to the ambulance with scarves around my eyes as the light was making my eyes hurt and the head pain was so unbearable. Once in hospital I was so dehydrated the doctors had problems getting a drip into me as they couldn’t get a vein. Eventually they did and started treating me for bacterial meningitis.”
“The hospital was very quick in sending me for a CT scan. They treated me with antibiotics and also sent me for eye scans and blood cultures. We soon knew it wasn’t bacterial but strongly suspected viral meningitis.”
Pointing to viral meningitis
“By then I was so poorly the doctors said they didn’t want to put me through a lumbar puncture as there was no cure for viral meningitis and they could tell from some of my results that everything was pointing to it being viral meningitis.”
“I was in hospital for a week. I have never been so ill! It took me a good six months before I started to feel fully well again, still suffering from neck aches. It was the most frightening experience. The only thing I didn’t have was the rash, which I knew would have meant bacterial meningitis.”
Wonderful care and support
“I feel so lucky to have had such wonderful care from the nurses and doctors at the hospital and my family and friends were amazing with their love and support. Always go with your gut instinct. For me, I know the signs of meningitis so I had a feeling I knew what was happening but if you don’t, please familiarise yourself with the symptoms because this can happen to anyone. Know the signs; it could save yours or a loved one’s life!”
“Having meningitis has made me realise how lucky I am as it could have been so much worse. My husband had to take over my role for a good month while I recovered and it has made him appreciate me and everything I do for him and our children.”

Causes
-
Meningitis
Viral infections are the most common cause of meningitis, followed by bacterial infections and, rarely, fungal infections. Because bacterial infections can be life-threatening, identifying the cause is essential.
Bacterial meningitis
Bacteria that enter the bloodstream and travel to the brain and spinal cord cause acute bacterial meningitis. But it can also occur when
bacteria directly invade the meninges. This may be caused by an ear or sinus infection, a skull fracture, or, rarely, after some surgeries.
Several strains of bacteria can cause acute bacterial meningitis, most commonly:
- Streptococcus pneumoniae (pneumococcus). This bacterium is the most common cause of bacterial meningitis in infants, young children and adults in the United States. It more commonly causes pneumonia or ear or sinus infections. A vaccine can help prevent this infection.
- Neisseria meningitidis (meningococcus). This bacterium is another leading cause of bacterial meningitis. These bacteria commonly cause an upper respiratory infection but can cause meningococcal meningitis when they enter the bloodstream. This is a highly contagious infection that affects mainly teenagers and young adults. It may cause local epidemics in college dormitories, boarding schools and military bases. A vaccine can help prevent infection.
- Haemophilus influenzae (haemophilus). Haemophilus influenzae type b (Hib) bacterium was once the leading cause of bacterial meningitis in children. But new Hib vaccines have greatly reduced the number of cases of this type of meningitis.
- Listeria monocytogenes (listeria). These bacteria can be found in unpasteurized cheeses, hot dogs and luncheon meats. Pregnant women, newborns, older adults and people with weakened immune systems are most susceptible. Listeria can cross the placental barrier, and infections in late pregnancy may be fatal to the baby.
Viral meningitis
Viral meningitis is usually mild and often clears on its own. Most cases in the United States are caused by a group of viruses known as
enteroviruses, which are most common in late summer and early fall. Viruses such as herpes simplex virus, HIV, mumps, West Nile virus and others also can cause viral meningitis.
Chronic meningitis
Slow-growing organisms (such as fungi and Mycobacterium tuberculosis) that invade the membranes and fluid surrounding your brain cause chronic meningitis. Chronic meningitis develops over two weeks or more. The symptoms of chronic meningitis — headaches, fever, vomiting and mental cloudiness — are similar to those of acute meningitis.
Fungal meningitis
Fungal meningitis is relatively uncommon and causes chronic meningitis. It may mimic acute bacterial meningitis. Fungal meningitis isn’t contagious from person to person. Cryptococcal meningitis is a common fungal form of the disease that affects people with immune deficiencies, such as AIDS. It’s life-threatening if not treated with an antifungal medication.
Other meningitis causes
Meningitis can also result from noninfectious causes, such as chemical reactions, drug allergies, some types of cancer and inflammatory diseases such as sarcoidosis.
Risk factors
Risk factors for meningitis include:
- Skipping vaccinations. Risk rises for anyone who hasn’t completed the recommended childhood or adult vaccination schedule.
- Age. Most cases of viral meningitis occur in children younger than age 5. Bacterial meningitis is common in those under age 20.
- Living in a community setting. College students living in dormitories, personnel on military bases, and children in boarding schools and child care facilities are at greater risk of meningococcal meningitis. This is probably because the bacterium is spread by the respiratory route, and spreads quickly through large groups.
- Pregnancy. Pregnancy increases the risk of listeriosis — an infection caused by listeria bacteria, which also may cause meningitis. Listeriosis increases the risk of miscarriage, stillbirth and premature delivery.
- Compromised immune system. AIDS, alcoholism, diabetes, use of immunosuppressant drugs and other factors that affect your immune system also make you more susceptible to meningitis. Having your spleen removed also increases your risk, and patients without a spleen should get vaccinated to minimize that risk.
Complications
Meningitis complications can be severe. The longer you or your child has the disease without treatment, the greater the risk of seizures and permanent neurological damage, including:
- Hearing loss
- Memory difficulty
- Learning disabilities
- Brain damage
- Gait problems
- Seizures
- Kidney failure
- Shock
- Death
With prompt treatment, even patients with severe meningitis can have good recovery.
Nicola, from Romford in Essex, had an excruciating headache that nothing would touch and knew something was seriously wrong. An ambulance was called and hospital doctors swiftly diagnosed viral meningitis. The 33-year-old mum tells her story here
“I woke up on Mothers’ Day with a terrible headache, thinking it was the start of a migraine. But this was different, the pain wouldn’t go, no matter the pain relief I took!”
“I tried to play it down as my children Ellie and Riley were trying to spoil me as it was Mothers’ Day but I just couldn’t move from my bed. I went to bed early that night and woke at 5am with the worst pain I have ever felt in my head. I instantly knew something was wrong and my husband Dale called for an ambulance.”
“By the time the ambulance had arrived the pain was unbearable. I collapsed in my mum’s arms and then started being violently sick once I came around. My neck was stiff and I had pain going down my back.”
Pain was unbearable
“My husband and mum had to carry me to the ambulance with scarves around my eyes as the light was making my eyes hurt and the head pain was so unbearable. Once in hospital I was so dehydrated the doctors had problems getting a drip into me as they couldn’t get a vein. Eventually they did and started treating me for bacterial meningitis.”
“The hospital was very quick in sending me for a CT scan. They treated me with antibiotics and also sent me for eye scans and blood cultures. We soon knew it wasn’t bacterial but strongly suspected viral meningitis.”
Pointing to viral meningitis
“By then I was so poorly the doctors said they didn’t want to put me through a lumbar puncture as there was no cure for viral meningitis and they could tell from some of my results that everything was pointing to it being viral meningitis.”
“I was in hospital for a week. I have never been so ill! It took me a good six months before I started to feel fully well again, still suffering from neck aches. It was the most frightening experience. The only thing I didn’t have was the rash, which I knew would have meant bacterial meningitis.”
Wonderful care and support
“I feel so lucky to have had such wonderful care from the nurses and doctors at the hospital and my family and friends were amazing with their love and support. Always go with your gut instinct. For me, I know the signs of meningitis so I had a feeling I knew what was happening but if you don’t, please familiarise yourself with the symptoms because this can happen to anyone. Know the signs; it could save yours or a loved one’s life!”
“Having meningitis has made me realise how lucky I am as it could have been so much worse. My husband had to take over my role for a good month while I recovered and it has made him appreciate me and everything I do for him and our children.”
Meningitis is a rare infection that affects the delicate membranes called meninges that cover the brain and spinal cord. 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
- Seizures
- 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:
- Fever
- Severe, unrelenting headache
- Confusion
- Vomiting
- 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.
