When Kate Daly was pregnant with twins she worried about the normal things mums worry about.
How to cope with two new babies, the lack of sleep, juggling life with four kids under the ages of four-and-a-half.
Her pregnancy was normal, she was fit and healthy.
So she never expected this.
Her twins born November 2011 both affected by a common virus.

One devastatingly so.
A virus so common in fact that half the population have been infected by adulthood and more than three quarters of people by the age of 40.
A virus that Kate herself contracted while she was pregnant and passed it unknowingly to her twins.
A virus that left her baby boy William with multiple disabilities including cerebral palsy and severe dyspraxia - and Kate didn’t even realise he had it until he failed an infant hearing test at three weeks old.
A virus that most of us have hardly ever heard of, have got a high chance of getting and is preventable.
