SIR - I’d like to remind families to look out for symptoms of meningitis, sepsis and other associated diseases, especially this time of the year. Traditionally in winter we see a sharp increase in infections that can cause meningitis and sepsis. These diseases often strike with incredible speed.

I lost my son 41 years ago to bacterial meningitis and sepsis. We now have five meningitis vaccines in the UK national immunisation programme. The highest incidence is in under-fives and ages15-24, including university students.

Sadly, we don’t have vaccines to protect against all infections causing meningitis and sepsis.

Spencer Dayman Meningitis Research is funding a pioneering vaccine development programme to prevent iGAS. In the meantime, knowing the symptoms ( followed by prompt medical intervention is crucial.
