Public health response to an outbreak of meningococcal B disease in a secondary school in Far North Queensland.

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.

A mass mortality event in bats caused by extreme heat: surprising public health challenges.

OBJECTIVES: We examine the public health response to an unprecedented multiple mortality event in bats following an extreme heat event. The main public health risk associated with the event and the environmental clean-up was potential human infection with Australian bat lyssavirus. We also consider the public health implications as we enter an age of climate change, vulnerability and unexpected events. Type of service: The Tropical Public Health Service of Far North Queensland worked collaboratively with the local council to coordinate a practical public health and health protection response to a mass mortality event in bats in late 2018. METHODS: A coordinated response was instigated to remove thousands of decaying bat corpses from residential areas. This occurred alongside a health education campaign advising the public to avoid handling bats. RESULTS: The combined efforts were successful; those requiring vaccination and post-exposure prophylaxis were treated appropriately and owing to a successful campaign, exposures were minimised. However, significant issues with misinformation and social media messaging were noted, alongside amateur bat carers handling sick and injured bats inappropriately, compounding the challenge for public health services. This mass mortality event has implications regarding the preparation for and management of other unexpected public health crises related to climate change. LESSONS LEARNT: It is vital that areas populated with bats be prepared for extreme heat events (EHEs). Public health units need to be prepared for the unexpected events of climate change, advocate for a 'one health' approach to public health, and work with local and national governments to become 'climate ready'.
