Another Case of Meningococcal Disease in Western Australia
The Western Australia Department of Health has reported another case of meningococcal disease, making it the 12th case in the state this year.
The young adult is recovering in hospital and, where appropriate, close contacts have been provided with antibiotics to minimise the chance of passing the organism onto others.
The incidence of meningococcal disease has decreased significantly in WA over the past decade, with around 20 to 25 cases reported each year—down from a peak of 86 cases in 2000. There were 19 cases notified in 2012, the lowest number recorded in more than 20 years.
A vaccine to protect against the C type of meningococcal disease, which in the past was responsible for around 15 per cent of cases in WA, is provided free to children at 12 months of age.
Meningococcal bacteria are carried harmlessly in the back of the nose and throat by about 10–20 per cent of the population at any one time. Very rarely, the bacteria invade the bloodstream and cause serious infections.
Meningococcal bacteria are not easily spread from person-to-person. The bacterium is present in droplets discharged from the nose and throat when coughing or sneezing, but is not spread by saliva and does not survive more than a few seconds in the environment.
Invasive meningococcal infection is most common in young children, older teenagers and young adults.
Symptoms may include high fever, chills, headache, neck stiffness, nausea and vomiting, drowsiness, confusion, and severe muscle and joint pains.
Sometimes—but not always—these symptoms may be accompanied by the appearance of a spotty red-purple rash that looks like small bleeding points beneath the skin or bruises.
Although treatable with antibiotics, the infection can progress very rapidly, so it is important that anyone experiencing these symptoms seeks medical attention promptly. With appropriate treatment, most people make a full recovery.
