Cases of invasive meningococcal disease have been confirmed in Kent. Sadly, 2 people are known to have died. It's important to know the signs of symptoms of meningitis and septicaemia. Get more info from NHS. 🔗 nhs.uk/conditions/meningitis
MENINGITIS SYMPTOMS:
fever
a very bad headache (this alone is not a reason to get medical help)
being sick
stiff neck
dislike of bright lights
rash (DO NOT wait for a rash to appear before seeking medical advice)
confusion, delirium
severe sleepiness, losing consciousness


SEPTICAEMIA SYMPTOMS:
fever and shivering
severe pains and aches in limbs and joints
cold hands and feet
pale or blotchy skin
very rapid or difficulty breathing
diarrhoea, stomach cramps
red or purple “blood spots” or blotchy rash on skin that does not fade under pressure – do the GLASS TEST. On dark skin, check other places such as the palms of the hands, soles of the feet, inside the mouth (roof), and the whites of the eyes
confusion, delirium
severe sleepiness, losing consciousness


If you become worried about yourself, your child, or a friend, particularly if symptoms are getting worse, seek medical help urgently.
EARLY TREATMENT CAN BE LIFE-SAVING.

Their parents never got them vaccinated. As young adults, they faced a choice.
Falling vaccination rates around the country mean more will grow up without protection from debilitating diseases until they are old enough to decide for themselves, typically at age 18.
