RESUMO
This article describes the public health response to an outbreak of meningococcal B disease, linked to a secondary school in Far North Queensland. Tropical Public Health Services in Cairns were notified of three cases of meningococcal disease in the same week in May 2022. The cases occurred in individuals who all attended, or worked in, the same secondary school. All cases were serogroup B and shared the same molecular genotype. The public health response included prompt provision of information, distribution of clearance antibiotics and two doses of MenB-4C vaccine to the entire staff and student population. Antibiotic coverage and vaccination coverage were achieved in 99% and 85% of the student population respectively. Following the intervention, no further cases were detected in the region during the subsequent nine months.
