Sporadic household clusters of meningitis could appear over the next four weeks in other parts of the UK linked to the travel of people away from Kent, a health chief has said.
Cases linked to the outbreak - that has claimed two lives - have now been confirmed at two universities and four schools in Kent, as well as an animation and gaming college in London.
Escape Studios in Greenwich, in the south east of the capital, said one of its students had been rushed to hospital after contracting the “unprecedented” bug.
Kent County Council's director of public health Dr Anjan Ghosh said on Friday three scenarios were being looked at over the next four weeks, with the most likely being that students who have travelled away from Kent will "incubate" the bug and there could be "household" cases elsewhere.
However, he said these would be "containable" and urged people to carry on with their lives.
A "worst-case scenario", would result in another cluster outside of Kent. However, he said this is "highly unlikely", with the other scenario "most likely to be the case".
There is also a chance no further cases could be seen outside Kent.
It comes as the UK Health Security Agency (UKHSA) said the number of cases linked to the outbreak has reached 29, up from 27 previously. While a rise, it has not as big a jump in cases as in previous days.
Some 18 cases have been confirmed, alongside a further 11 "probable cases" - all with links to Kent, the UKHSA said.
Dr Ghosh said it is "too early to say" if the number of cases in the outbreak has peaked.
He said: "Hopefully it's starting to slow down. I think until next week, we won't be able to say for sure, the normal sequelae of an outbreak of this sort is about four weeks.
"That's the timeframe for it to really slow down. So fully expect, in four weeks' time that it slowed down, but we can't say whether it's peaked yet."
Earlier, the family of a 18-year-old sixth form student who died from meningitis in the Kent outbreak described their “immeasurable loss”.
The family of Juliette Kenny, 18, are campaigning for teenagers and young people to be routinely given access to the meningitis B vaccination.
A 21-year-old University of Kent student, has also died during the outbreak.
On Friday the meningitis vaccine rollout was underway again after anger more than 100 students were turned away from a vaccination centre on the University of Kent's Canterbury campus on Thursday.
Hundreds queued at a campus sports centre amid a high demand for MenB jabs, but officials closed the queue because it had hit capacity, as keeping to staffing hours meant the clinic needed to finish by 5pm.
By 8.45am on Friday, round 700 staff and students were in the queue, according to estimates by PA reporters at the scene.
One student near the front said she had joined the queue at 7.55am. The clinic is operating from 9am to 5pm, with students told to join the queue by 2pm.
The chief scientific officer of the UKHSA, Professor Robin May, said a "staffing issue" led to people being turned away on Thursday.
He told Times Radio: "Yesterday, it was a staffing issue. To emphasise - we are not short of vaccine. Yesterday, demand exceeded the ability of staff to fulfil it within the time allocated."
As of 5pm on Thursday, some 2,360 vaccinations have been given and 9,840 doses of antibiotics to those affected by the outbreak, according to NHS figures.
The University of Kent and Canterbury Christ Church University have already confirmed to have people infected with meningitis, as have five schools in the county.
The vaccine rollout has now been expanded to include anyone who attended the Club Chemistry venue in Canterbury from March 5 to March 15, where the outbreak is believed to have originated.
Year 12 and 13 pupils at affected schools, students and staff at both universities, and close contacts of confirmed or suspected cases will also be eligible, as will those previously eligible for antibiotics.
Health Secretary Wes Streeting announced 20,000 doses of the vaccine would be released to the private market to help ease shortages.
Deputy chief executive of NHS Kent and Medway Ed Waller said there are "plenty" of doses of vaccine available in Kent and the advice to people queuing is to "just think about where they go", with other clinics open.
"The other two sites are operating - they're less busy than this one. So, we will see as many of the people who are in the queue as we can today."
When asked about the closing times of the vaccine centres, he said: "We are trying to maximise the capacity and the opening hours of all the sites.
"So we are in the process of operationalising as much capacity as we can."
He said a request was made on Friday for a further 5,000 doses of vaccine.
He said: "6,500 doses of vaccine have been delivered to Kent and Medway from the national stock. There was a request today for a further 5,000."
Elsewhere, Paul Hunter, professor in medicine at the University of East Anglia, said the "peak" of the initial meningitis "superspreading event" at Club Chemistry may have passed.
However, secondary cases affecting people who were not infected at the nightclub, but caught the illness from someone who was there, are still a possibility, he said.
"The incubation period, though a little uncertain, ranges from two to 10 days so I think we can be fairly certain that the peak from the initial superspreading event will have already passed.
"The question remains whether there will be any secondary cases i.e. any cases that didn't get their infection from the nightclub but from someone else who did attend.
"Hopefully the antibiotic and vaccine will prevent those but it is still a possibility.
"Even if we do see secondary cases, I doubt there will be as many as in the primary wave, though cannot be certain."
Prof May told Times Radio experts are still trying to work out if the meningitis bug has become more transmissible in the recent cases.
The UKHSA has said the Bexsero vaccine for menB used on the NHS should offer protection against the strain identified, and it published details of an "initial genetic analysis" of the strain.
Similar strains have been circulating in the UK for around five years but more detailed analysis is required, the UKHSA said, as it invited researchers to look at its code in detail.
Asked if such an outbreak could happen again, Prof May said: "Well obviously that's something we're very conscious of.
"We'll be mindful both of the possibility of this particular strain, for example, re-emerging in the future, but also general principles that we'll learn about the bacteria.
"As with all pathogens, there's always much more we can learn, and by learning more about how they work, we hope to develop better ways to prevent them causing disease in the future."
