To perform the meningitis glass test, press the flat side of a clear drinking glass firmly against a rash and observe whether it fades or disappears under the pressure. If the rash does not fade and remains visible through the glass, this may indicate a meningococcal septicaemia rash — a medical emergency that requires an immediate call to 999 or a trip to the nearest accident and emergency department. It is important to understand that the glass test is a useful awareness tool, not a diagnostic test — and that meningitis can be life-threatening even in the absence of a rash, making prompt medical attention essential whenever meningitis is suspected. Edinburgh Travel Clinic strongly advises all travellers to brush up on the signs and symptoms of meningitis and check that their vaccination is current before travel, with particular urgency for those heading to high-risk destinations or attending large gatherings abroad.
If your travel plans take you to a destination where meningitis is a known risk, speaking to a specialist before you go could be one of the most important steps you take.

- Meningococcal disease can be fatal within 24 hours — if you suspect meningitis, call 999 immediately without waiting for a rash to appear.
- Not everyone with meningitis develops a rash — other symptoms such as severe headache, stiff neck, and sensitivity to light require urgent attention.
- Meningitis vaccination is strongly recommended for travellers visiting sub-Saharan Africa’s Meningitis Belt and those attending the Hajj or Umrah pilgrimage.
- Vaccination is the single most effective measure for preventing bacterial meningitis — speak to a travel health professional before your trip.
The Dangers of Meningitis
Meningitis is an inflammation of the membranes surrounding the brain and spinal cord, most commonly caused by bacterial or viral infection. Bacterial meningitis — particularly that caused by Neisseria meningitidis (meningococcal disease) — is the most serious form and can progress from the first symptoms to death within 24 hours if left untreated. Even with prompt treatment, bacterial meningitis can result in life-altering complications including hearing loss, brain damage, limb amputation, and organ failure.
According to Meningitis Now, approximately 1 in 10 people who develop bacterial meningitis will die, and a further 1 in 5 will be left with a significant long-term disability. These statistics make meningitis one of the most feared infectious diseases worldwide — and one that every traveller heading to high-risk destinations must take seriously. Understanding the warning signs, knowing how to perform the glass test, and ensuring vaccination is current are three of the most important things anyone can do to protect themselves and those around them.
Recognising the Symptoms of Meningitis
Speed is everything when it comes to meningitis. Recognising the symptoms early and acting without hesitation can be the difference between life and death. Symptoms can develop rapidly, often within hours, and do not always present in a predictable order.
Common Signs and Symptoms of Meningitis
- Severe headache
- High temperature (fever)
- Stiff neck
- Sensitivity to light (photophobia)
- Sensitivity to sound (phonophobia)
- Nausea and vomiting
- Drowsiness or confusion
- Seizures
- Cold hands and feet
- Pale, blotchy, or mottled skin
- A rash that does not fade under pressure
- Bulging fontanelle in infants
It is vital to remember that not everyone with meningitis develops a rash — and in some cases, the rash may appear only in the later stages of the illness. Never wait for a rash to appear before seeking emergency medical help if other symptoms of meningitis are present. Call us to start a consultation and protect yourself before you travel.
How to Do the Meningitis Glass Test: Step by Step
The glass test is a simple but important awareness check that can be performed by anyone. Follow the steps below carefully — and remember that this test should always be used alongside other symptom recognition, never as a standalone diagnostic tool.
Identify the Rash
Look for small, flat, red, purple, or brown spots (petechiae or purpura) on the skin. These spots do not have a raised surface and may initially resemble small bruises or pinprick marks. Check areas including the trunk, legs, and — in people with darker skin tones — the palms, soles, and inside the mouth.
Use a Clear Glass or Transparent Object
Take a clear drinking glass or any transparent object with a flat surface. The transparency is essential — you must be able to see the rash clearly through the glass throughout the test.
Press Firmly Against the Rash
Press the flat side of the glass firmly and steadily against the rash, applying enough pressure to cause the surrounding skin to whiten or blanch. Hold it in place for a few seconds.
Observe Carefully
Look at the rash through the glass while pressure is applied. A rash that fades or disappears under pressure is less likely to be a meningococcal septicaemia rash. A petechial or purpuric rash that remains clearly visible and does not fade under pressure is a serious warning sign requiring immediate emergency action.
Act Immediately if the Rash Does Not Fade
If the rash does not fade under the glass, call 999 without delay. This is a potential sign of meningococcal septicaemia — a life-threatening emergency. Do not wait to see if the rash spreads or other symptoms worsen before calling for help.
The Limitations of the Glass Test
While the glass test is a valuable and widely recognised tool for identifying a potential meningococcal rash, it has important limitations that every person should be aware of. The most significant is that the absence of a non-fading rash does not mean meningitis is absent. Many people with meningitis never develop a rash at all, and in others the rash may not appear until the illness is already well advanced.
A rash that fades under the glass — known as a blanching rash — can still be associated with serious illness and should not automatically be dismissed as harmless. Viral rashes, allergic reactions, and other conditions can produce blanching rashes, and anyone who is seriously unwell with symptoms consistent with meningitis should receive urgent medical attention regardless of the outcome of the glass test.
The glass test should therefore always be used as an addition to — never a replacement for — clinical judgement and prompt medical assessment. If in any doubt, call 999 or go immediately to accident and emergency.
Meningitis Vaccination for Travellers
Vaccination remains the most effective strategy for preventing bacterial meningitis, and several meningococcal vaccines are available in the UK. The MenACWY vaccine protects against four strains of meningococcal disease (A, C, W, and Y) and is strongly recommended for travellers visiting sub-Saharan Africa’s Meningitis Belt — a region stretching from Senegal in the west to Ethiopia in the east — particularly during the dry season between December and June, when transmission risk is at its highest.
The MenACWY vaccine is also a mandatory requirement for travellers undertaking the Hajj or Umrah pilgrimage to Saudi Arabia, where large gatherings create a heightened risk of meningococcal disease transmission. Saudi authorities require proof of vaccination with the quadrivalent meningococcal vaccine issued within the last five years as a condition of entry for pilgrims. In addition to the MenACWY vaccine, a separate MenB vaccine is available and provides protection against meningococcal group B disease, which accounts for the majority of bacterial meningitis cases in the UK.
While meningitis vaccination is a vital consideration for many travellers, it is rarely the only one. Enter your travel destination below to discover the full range of vaccinations Edinburgh Travel Clinic may advise for your trip:
The duration of protection from the MenACWY vaccine varies depending on the specific vaccine brand and individual factors — your clinician will advise on when a booster is recommended based on your vaccination history and ongoing risk.

Frequently Asked Questions
We have put together clear answers to the meningitis glass test and meningitis vaccination questions we are asked most often — and our team is always here if you need more personalised advice.
What does it mean if the rash fades during the glass test?
A rash that fades or blanches under pressure is less likely to be a meningococcal septicaemia rash, but this does not rule out meningitis or other serious illness. If the person is unwell and showing other symptoms of meningitis, seek emergency medical help immediately regardless of the glass test result.
Can you get meningitis without a rash?
Yes — not everyone with meningitis develops a rash, and in some cases the rash may appear only in the later stages of the illness or not at all. This is why the glass test should never be relied upon as the sole indicator of meningitis and why any combination of other symptoms should be treated as a medical emergency.
Which meningitis vaccine do I need for travel?
The most commonly recommended travel vaccine is the MenACWY vaccine, which protects against four strains of meningococcal disease and is required for Hajj and Umrah pilgrims and recommended for travel to the Meningitis Belt in sub-Saharan Africa. Your travel health clinician will advise on the most appropriate vaccine or combination of vaccines based on your destination and individual circumstances.
How long does the meningitis vaccine last?
The duration of protection from the MenACWY vaccine varies depending on the specific vaccine brand and individual factors, and your clinician will advise on when a booster is recommended based on your vaccination history and ongoing risk. The MenB vaccine schedule and duration of protection differ and should also be discussed with your travel health clinician.
Is meningitis contagious?
Bacterial meningitis can be spread through close contact with an infected person via respiratory droplets — for example through coughing, sneezing, or kissing — but it is not as easily transmitted as infections such as influenza or COVID-19. Most people who come into contact with someone who has meningitis do not become ill, but close contacts are typically offered preventive antibiotics as a precaution.
Should I get the meningitis vaccine if I am travelling to Europe?
Meningococcal disease occurs throughout Europe, including the UK, and the MenACWY and MenB vaccines are part of the UK childhood immunisation programme. If you are unsure whether your vaccinations are current, a pre-travel consultation with a travel health specialist is the best way to review your status and ensure you are appropriately protected for your destination.
Meningitis Awareness Could Save a Life
Meningitis is one of the most serious infections a traveller can encounter — but it is also one of the most preventable. Knowing how to perform the glass test, understanding that the rash associated with meningococcal septicaemia typically appears as small, flat petechiae or purpura that do not fade under pressure, and recognising the full range of symptoms could genuinely save a life. And while the glass test is a powerful awareness tool, it works best when combined with the broader knowledge of what meningitis looks and feels like in its earliest stages.
Every patient who walks through the door at Edinburgh Travel Clinic can expect meningitis vaccination and awareness to be a central part of their pre-travel health consultation, not an afterthought. Whether you are heading to the Meningitis Belt, preparing for Hajj, or simply want to make sure your vaccinations are up to date, our specialist team is here to help. Book now and set off on your adventure knowing you have done everything possible to protect yourself and those around you.
