No not nonsense Musukebba.
Before the introduction of the MMR the mumps single vaccine was very little used because mumps was not considered to be a disease serious enough to warrant vaccination (and the vaccine was not terribly effective).
Before 1988 mumps was not even a notifiable disease. Mumps is sub-clinical in around 30% to 40% of cases.
Epidemiology and medical books from the pre vaccine period state that meningitis occurred in less than 2.5% of clinical cases. This equals less than 1% of total cases. The prognosis for mumps meningitis is good and there is no specific treatment.
How this has suddenly inflated into figures like 10% I don't quite know. (Actually to be fair the NHS quotes a remarkably large ballpark figure of between 1 and 10%).
This what they have to say on both meningitis and pancreatitis;
Pancreatitis
The most common symptom of pancreatitis is the sudden onset of pain in the centre of your upper abdomen. Other symptoms of acute pancreatitis can include:
- nausea,
- vomiting,
- diarrhoea,
- loss of appetite,
- high temperature (fever) of 38C (100F), or above,
- tenderness of the abdomen and, less commonly,
- yellowing of the skin and the whites of the eyes (jaundice).
Although pancreatitis that is associated with mumps is usually mild, admission to hospital may be recommended so that the functions of your body can be supported until your pancreas recovers.
Viral meningitis
Viral meningitis is a viral infection of the outer membranes (meninges) of your brain and spinal cord.
Unlike bacterial meningitis, which is regarded as a potentially life-threatening medical emergency, viral meningitis causes much milder, flu-like symptoms, and the risk of serious complications are low.
Symptoms of viral meningitis include:
- high temperature (fever) of 38C (100F), or above,
- sensitivity to light (photophobia),
- headache,
- nausea, and
- vomiting.
The symptoms of viral meningitis will usually pass within 14 days
I don't think it is helpful to bandy sinister sounding conditions like meningitis and pancreatitis about without putting them into some sort of context.
