AN adult is recovering after being diagnosed with meningococcal disease serogroup B in Western Australia.
It brings the number of reported cases of the uncommon, life-threatening illness this year to 16, the WA Health Department said on Monday.
This year there have been five serogroup B, six serogroup W and five serogroup C meningococcal infections.
Symptoms of invasive meningococcal disease may include high fever, chills, headache, neck stiffness, nausea and vomiting, drowsiness, confusion, and severe muscle and joint pains.
Young children may not complain of symptoms, so fever, pale or blotchy complexion, vomiting, lethargy (inactivity), poor feeding and rash are important signs.
Although treatable with antibiotics, meningococcal infection can progress very rapidly, so it is important that anyone experiencing these symptoms seeks medical attention promptly.
