How worried should we be?published at 12:30 GMT

The meningitis outbreak has been described as an unprecedented and explosive event.
But at the same time we are being told it’s not like Covid and there’s low risk of it spreading nationwide - so how do we reconcile those two things?
It’s true this outbreak is highly unusual. You don’t normally get such a concentration of cases all at one time.
When cases occur in clusters, it's often limited to only three or four cases. So to have 20, seemingly linked, is hardly ever seen.
Meningitis does not spread super easily. Sitting next to someone on a bus is not considered a risk, for example. It normally requires very close contact involving the exchange of saliva - such as kissing or sharing drinks or vapes.
What is more, many of us already have the bacteria that causes it in the back of our throats and in our noses – and it doesn’t cause a problem.
Only in rare cases does it lead to invasive meningitis, involving brain inflammation and blood poisoning - there are only around 300 to 400 of those cases every year.
It’s why experts in the field continue to say the risk, even to people in Kent, is very small.
But the unanswered question, of course, is why this has happened.
It could just be completely random or a freak event with a particular set of unique circumstances. Or, and this is very much worst-case scenario, it could have mutated.
While the health authorities cannot rule that out – they are carrying out tests to check – their working assumption is it hasn’t.
