Five new cases of meningitis have been reported in Kent, taking the total number being investigated by health officials to 20.
The UK Health Security Agency (UKHSA) said that, as of 5pm on Tuesday, some 20 cases of meningitis had been reported to it, up from 15 on Tuesday.
Of these, nine cases have been confirmed in the lab and 11 remain under investigation.
Six of the confirmed cases have been confirmed as the meningitis B strain.
A statement said: “All those affected who are currently linked to the outbreak are young adults.
“UKHSA is aware of a baby with confirmed meningococcal group B infection who is not currently linked to the outbreak but UKHSA will continue to investigate this case.”
GPs across the country have now been told to prescribe antibiotics to anyone who visited a nightclub in Canterbury from March 5-7, plus students from the University of Kent.
This is to ensure anyone who has left campus can make sure they get the right treatment.
The UKHSA said: “This is a rapidly evolving situation and there may be further cases as those with symptoms are encouraged to seek medical advice.
“Antibiotics remain the most effective treatment to limit the spread of invasive meningococcal disease.
“So far, over 2,500 doses have been given to students, close contacts and others including some of those who attended Club Chemistry between March 5-7.
“GPs across the country will today be advised to prescribe antibiotics to anyone who visited Club Chemistry between March 5-7 and to University of Kent students, if they have been asked to seek preventative treatment.
“This is so that anyone who has travelled home, or away from Kent, can easily access this important preventative treatment close to them.”
Trish Mannes, UKHSA regional deputy director for the South East, said antibiotics are “the main intervention that will help protect people and halt the spread of the outbreak”.
She added: “As a further precaution and together with the NHS, we are beginning to roll out a targeted menB vaccination programme.
“This will initially be offered to 5,000 University of Kent students resident at the Canterbury campus, with the possibility that it may be extended, as it is kept under continual review.
“If you think you may have symptoms of meningitis, don’t hesitate to seek medical help by contacting your GP or calling NHS 111.
“Seeking early treatment can save lives.”
