i was watching that programme 'how clean is your house' a bit ago and remember them taking a swab from a particularly dirty house, and they found a bacteria that they said could cause meningitis.
this got me thinking...an aquaintence of mine, well her dd had meningitis as a baby, not sure what strain. her house was really filthy,she never cleaned it, it was really bad, plus she had a couple of large dogs and a few cats in there.when the child was recovering(so lucky) in hospital, she had to fill out a questionaire, asking them about their lifestyle,and living arrangements, whether they had pets, central heating and so on. i was just wondering whether their is really a connection, does anybody else know? i thought it was carried by humans in the nasal passages..
