A young child is recovering in hospital after becoming the first person this year diagnosed with serogroup B meningococcal disease in Western Australia.
The incidence of the disease decreased significantly in WA - down from a peak of 86 cases in 2000 to a low of 16 cases in 2013, the WA Health Department says.
But it is increasing again due to new virulent strains of serogroup W, and to a lesser extent serogroup Y.
