Sheryl Martin still cringes when she sees someone sharing a drink bottle, having seen what her daughter Sara went through when she was diagnosed with meningitis eight years ago.
"Just today, my husband and I were sitting in a cafe and I see two little boys - pre-schoolers - sharing a drink. I said to [my husband], 'What do you want to do?' He said: 'I want to go grab it off them'.
"That's what I think every time, and that's how meningitis has impacted our family," Mrs Martin said.
Sara, now 29, had just graduated from university when she was struck down by the condition in June 2004.
"I was at work ... and I suddenly felt sick and really tired, so I went and had a little sleep in my car. When I woke up, I felt like I'd been hit by a bus.
