Five meningococcal cases have been reported in the state over the past year.
About 18 meningococcal cases were reported with no deaths last year.
The illness, which could be life-threatening, is 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.
Symptoms include sudden fever, headache, tiredness, nausea and vomiting, drowsiness, confusion and severe muscle and joint pains.
