Freshers’ week is designed to bring new students together. But the same close contact that helps friendships form can also help infections spread.
Most cases of so-called “freshers’ flu” are relatively mild. Meningococcal disease is different. Although rare, it can develop rapidly and become life-threatening within hours.
In England, first-year university students are around seven times more likely to develop meningococcal disease than young people of a similar age who do not attend university.
The danger was highlighted in March 2026, when an outbreak of meningococcal group B, or MenB, around Canterbury involved 21 confirmed cases among students and other young people. Two people died.
Meningococcal bacteria can cause meningitis and sepsis. Meningitis affects the protective layers surrounding the brain and spinal cord, while sepsis occurs when the body’s response to infection causes potentially life-threatening damage. Survivors of meningococcal disease can be left with serious complications including hearing loss, neurological damage and limb amputation.
So why are students particularly vulnerable?
Why university increases the risk?
One of the unusual things about neisseria meningitidis, commonly called meningococcus, is that it can live harmlessly in the nose and throat without causing disease. This is known as carriage, and it is particularly common among teenagers and young adults.
Most people who carry the bacteria never become ill. But the bacteria can spread through close or prolonged contact, and university creates plenty of opportunities for that to happen.
Thousands of people from different places suddenly begin living, studying and socialising together. Research among British teenagers and university students has linked meningococcal carriage with attending pubs and clubs, intimate kissing and cigarette smoking.
A UK study of first-year university students found that meningococcal carriage increased from 6.9% on their first day at university to 23.1% by day four. The research was conducted more than 25 years ago, before today’s meningococcal vaccination programmes, so those figures should not be taken as estimates of current carriage rates. But they illustrate how rapidly meningococci can circulate when new social networks form.
More recent research suggests that the pattern has not disappeared. A 2026 study of US college students found carriage increased over the course of a semester, with smoking or vaping, kissing and sexual contact associated with carriage.
Carrying meningococcus does not mean someone will develop meningitis, and most carriers do not become ill. Increased circulation does, however, create more opportunities for the bacteria to reach somebody in whom they invade the bloodstream or tissues surrounding the brain.
Vaccination provides important protection, but different vaccines protect against different groups of meningococcal bacteria. The MenACWY vaccine protects against groups A, C, W and Y, while the MenB vaccine is designed to protect against group B. Recent surveillance shows that MenB caused 97% of invasive meningococcal disease cases among 15 to 24-year-olds in England in 2025-26.
What students should do
Students heading to university should first check which vaccinations they have already received.
In England, teenagers are routinely offered the MenACWY vaccine at school. Anyone under 25 who missed it can ask their GP about catching up, ideally before starting university.
There is also a one-off MenB vaccination programme in England in 2026. It includes people born between September 1 2007 and August 31 2008, and people born on or after July 21 2001 who are starting university for the first time in autumn 2026. Some young people starting at residential further-education colleges are also eligible.
The MenB vaccine is given in two doses at least four weeks apart. Eligible young people can book through the NHS website, attend participating pharmacy walk-in services or call 119 if they cannot book online.
Vaccination is only one layer of protection because early meningococcal disease can look remarkably similar to illnesses common during freshers’ week. Fever, headache, vomiting and muscle aches can resemble flu or other common infections, or even be mistaken for the effects of a bad hangover.
Warning signs can include a stiff neck, sensitivity to bright light, confusion, extreme drowsiness, seizures, cold hands and feet, or becoming much more unwell over a matter of hours.
The familiar dark purple or red rash that does not disappear when pressed with a glass can be an important warning sign, but a rash does not occur in everyone and may appear late. Students should never wait for a rash before seeking urgent medical help if meningitis or meningococcal disease is suspected.
Checking vaccination records before starting university gives students important protection. Recognising the symptoms is equally important.
And if a friend or flatmate seems unusually ill or is difficult to wake, check on them rather than assuming they are sleeping off the night before. UKHSA advises checking regularly on somebody who has gone to bed unwell because meningococcal disease can deteriorate rapidly. Getting medical help quickly could save their life.
