Meningitis Symptoms: How to Recognise the Signs in Adults, Teenagers and Children
Medically reviewed by The Online GP by The Wellness Medical Team — Last updated: 19 March 2026
Meningitis can kill within 24 hours, and early recognition of symptoms is the single most important factor in survival. The key warning signs include a sudden high temperature, severe headache, stiff neck, sensitivity to bright lights, vomiting, confusion, cold hands and feet, and a rash that does not fade when pressed with a glass. Symptoms can appear in any order, may develop within hours, and some may not appear at all. If you suspect meningitis in yourself or someone else, call 999 or go to A&E immediately — do not wait.
If you are worried about meningitis symptoms right now, call 999. This is a medical emergency.

The Symptoms of Meningitis and Septicaemia
Meningococcal disease can present as meningitis (infection of the membranes surrounding the brain and spinal cord), septicaemia (blood poisoning), or both simultaneously. The symptoms differ slightly between these presentations, and they can appear in any order — there is no predictable sequence.
Meningitis symptoms include a sudden, severe headache that feels different from a normal headache, a high temperature (fever) of 38°C or above, a stiff and painful neck — particularly difficulty bending the chin to the chest, sensitivity to bright lights (photophobia), nausea and vomiting, confusion, difficulty concentrating, or altered mental state, drowsiness or difficulty waking, and seizures (fits).
Septicaemia symptoms include a high temperature, cold hands and feet despite having a fever, rapid breathing, pale, mottled, or blotchy skin (which may be harder to see on darker skin), muscle and joint pain, a non-blanching rash (the characteristic spots or blotches that do not fade under pressure), and in severe cases, leg or body pain, abdominal pain, or diarrhoea.
In many cases, meningitis and septicaemia occur together, and a person may display symptoms from both lists. The critical point is that you do not need to see all symptoms to act. Any combination of severe headache, high temperature, and stiff neck — or a non-blanching rash — should prompt an immediate call to 999.
The Glass Test: How to Check a Meningitis Rash
The glass test is a simple, widely recommended method for checking whether a rash could indicate meningococcal septicaemia.
Take a clear drinking glass and press the side of it firmly against the rash. Watch carefully to see whether the spots fade under the pressure of the glass. If the spots or marks do not fade — that is, you can still see them clearly through the glass — this is a non-blanching rash. It may indicate meningococcal septicaemia, which is a medical emergency. Call 999 immediately.
If the rash does fade under pressure, it is less likely to be meningococcal septicaemia. However, if other symptoms are present (fever, headache, stiff neck, confusion), you should still seek urgent medical advice.
There are important caveats to be aware of. The rash may not appear at all — many people with meningitis never develop a visible rash. The rash may appear late, sometimes only in the final hours of illness. On darker skin tones, the rash may be harder to see — check lighter areas such as the palms of the hands, soles of the feet, the inside of the eyelids, and the roof of the mouth. In its early stages, the rash may look like small pinprick-sized spots before developing into larger blotches.
Never wait for a rash before seeking help. The rash is a sign of septicaemia, which means the infection is already in the bloodstream. Earlier symptoms should prompt action long before a rash develops.
Why Meningitis Symptoms Are So Easily Missed
One of the most dangerous aspects of meningococcal disease is that its early symptoms closely resemble common, benign illnesses. A high temperature, headache, muscle aches, and nausea could be flu, a stomach bug, a bad cold, or — as the UKHSA pointedly warned during the Kent outbreak — a hangover.
This is particularly dangerous for teenagers and university students. In the context of the 2026 Kent outbreak, many of the cases were linked to a nightclub event. For a university student who has been out socialising, waking up the next day with a headache, nausea, and fatigue would normally be attributed to a late night and alcohol. The possibility of meningitis may not even cross their mind.
UKHSA's Regional Deputy Director Trish Mannes specifically highlighted this risk, stating that "students are particularly at risk of missing the early warning signs of meningitis because they can be easily confused with other illnesses such as a bad cold, flu or even a hangover."
The key differentiators that should raise alarm are the speed of onset (meningitis symptoms develop over hours, not days), the severity of the headache (patients often describe it as the worst headache of their life), neck stiffness (a distinctive symptom not typically associated with hangovers or flu), photophobia (sensitivity to light), and cold extremities combined with a fever (cold hands and feet when the body is hot is a red flag).
If in doubt, always seek medical help. It is far better to attend A&E and be told it is not meningitis than to wait at home and miss a critical treatment window.
Symptoms in Different Age Groups
While the core symptoms of meningitis are similar across age groups, certain signs vary depending on the person's age.
Babies and young children may display a bulging fontanelle (the soft spot on the top of the head), a high-pitched or unusual cry, refusing to feed, irritability and not wanting to be held, becoming floppy or unresponsive, a blank or staring expression, and pale or blotchy skin. Babies may not display the classic stiff neck or headache that older children and adults experience, making the diagnosis more challenging. Trust your instincts — if your baby seems seriously unwell, seek emergency help.
Children and teenagers are more likely to show the classic symptom triad of fever, headache, and neck stiffness, along with vomiting, sensitivity to light, confusion, and drowsiness. They may complain of severe leg or body pain, which can sometimes be mistaken for growing pains or a sports injury.
Adults typically present with severe headache, fever, neck stiffness, photophobia, confusion, nausea, and vomiting. In older adults, confusion may be the most prominent symptom, and neck stiffness may be attributed to pre-existing musculoskeletal conditions, potentially delaying diagnosis.
How Fast Does Meningitis Progress
The speed at which bacterial meningitis can deteriorate is one of its most frightening characteristics. While the typical progression from first symptoms to a medical emergency is 12–24 hours, in some cases the disease can progress from non-specific illness to critical condition in as little as 3–5 hours.
The incubation period — the time between being infected and developing symptoms — is typically 2 to 10 days for meningococcal disease, with most cases developing symptoms within 3–4 days of exposure. During the incubation period, the person may feel entirely well.
Once symptoms begin, the progression can be rapid. A person may feel mildly unwell in the morning, develop a worsening headache and fever by midday, and be critically ill by the evening. This is why every major health authority emphasises the importance of early treatment — delays of even a few hours can be the difference between full recovery and death or permanent disability.
If someone appears to be deteriorating — even if they were seen by a doctor earlier and told it was not meningitis — seek help again immediately. Meningitis can be difficult to diagnose in its earliest stages, and a second assessment may reveal symptoms that were not yet apparent.
Prevention: How to Reduce Your Risk
While recognising symptoms is critical for survival, prevention is always preferable. There are several evidence-based measures that reduce the risk of meningococcal disease.
Vaccination is the most effective preventative measure. The Bexsero vaccine protects against approximately 88% of MenB strains circulating in the UK. Most people born before 2015 are unvaccinated against MenB and should consider private vaccination. The Online GP by The Wellness is currently operating a waiting list for MenB vaccination due to the national shortage — contact us to register your interest. MenACWY vaccination may be available immediately.
Antibiotics — if you have been identified as a close contact of a confirmed meningitis case, prophylactic antibiotics (typically ciprofloxacin) reduce your risk by approximately 80–90%. Take them if offered; do not skip them.
Hygiene and behaviour — avoid sharing drinks, cutlery, vapes, and cigarettes, particularly with people you do not know well. These are primary transmission routes for meningococcal bacteria.
Awareness — simply knowing the symptoms and knowing to act quickly can save your life or the life of someone you love. Share this information with your family, flatmates, and friends.

Frequently Asked Questions
What are the first signs of meningitis?
Early symptoms resemble a bad cold or flu — high temperature, feeling unwell, irritability, loss of appetite. These can rapidly progress to severe headache, stiff neck, sensitivity to light, vomiting, confusion, and cold hands and feet. Symptoms can develop within hours.
What does the meningitis rash look like?
Small red or purple spots that do not fade when pressed with a glass. They may start as tiny pinpricks and develop into larger blotches. The rash can appear anywhere on the body and may be harder to see on darker skin. Check palms, soles, inner eyelids, and the roof of the mouth.
Can you have meningitis without a rash?
Yes. Many people with meningitis never develop a rash, or the rash appears very late. Never wait for a rash before seeking help. Fever, severe headache, and stiff neck alone should prompt an immediate 999 call.
How quickly does meningitis develop?
Symptoms can progress from mild illness to life-threatening emergency within 3–24 hours. The speed of deterioration is one of the most dangerous features of the disease.
What should I do if I think someone has meningitis?
Call 999 immediately. Do not wait. While waiting, keep the person comfortable and away from bright lights. Note their symptoms and timing to share with paramedics. Trust your instincts — if someone is seriously unwell, always seek emergency help.
Can meningitis be mistaken for a hangover?
Yes, and this is particularly dangerous for students and young adults. Early symptoms (headache, nausea, fatigue) overlap with a hangover. Key differences include the severity and speed of onset, neck stiffness, photophobia, and cold extremities. If in doubt, seek medical help.
How can I protect myself from meningitis?
Vaccination is the most effective protection. The Online GP by The Wellness offers MenACWY vaccination and is operating a waiting list for MenB. Avoid sharing drinks and vapes. Take antibiotics if offered after close contact with a case. Know the symptoms and act fast.
