Mpox transmission dynamics can be suppressed by up to 97.85% when public health authorities combine vaccination, treatment, quarantine, and educational campaigns into a single strategy, according to mathematical modeling published by Hasanuddin University researchers in the journal Chaos, Solitons & Fractals. Professor Kasbawati from the Department of Mathematics released findings online on March 26, 2026, showing that coordinating multiple interventions yields a more cost-effective response than relying on any single measure during an outbreak.
Mathematical Modeling of Two Interacting Populations
The research team constructed a mathematical framework that tracks Mpox transmission across two distinct, interacting populations: humans and rodents. According to the study published in Volume 208 of Chaos, Solitons & Fractals on July 1, 2026, the human population was divided into nine distinct groups based on infection stages. Meanwhile, the rodent population was split into three groups to capture cross-species transmission pathways.
By accounting for asymptomatic infections in humans and latent infections in rodents, the model evaluates transmission routes often missed by traditional assessments. According to Prof. Kasbawati, previous studies frequently focused on a smaller number of interventions, whereas this new framework assesses the combined effects of multiple public health measures simultaneously.
Simulating Four Interventions for Optimal Outbreak Control
Simulations tested various combinations of four core measures: vaccination, treatment, quarantine, and educational campaigns. Vaccination was modeled to reduce host susceptibility, while treatment aided patient recovery and limited disease severity. Quarantine protocols lowered infectious contacts, and educational campaigns encouraged protective behaviors across communities.
Did you know? The full-control strategy combining all four interventions achieved a 97.85% reduction in total human infections compared to scenarios with no intervention, making it the most cost-effective option tested.
Different interventions hold peak value at specific stages of an outbreak, according to the simulation data. Quarantine and educational campaigns deployed intensively during early phases helped suppress rapid transmission. Pharmaceutical measures, including vaccination and treatment, were introduced from the beginning and maintained throughout the simulated timeline.
Addressing Rodent Reservoirs and Long-Term Endemic Risk
The analysis evaluated two primary disease states: the Mpox-free equilibrium, where transmission halts in both populations, and the endemic equilibrium, where the virus persists. Results indicate that while human-to-human transmission drives short- and medium-term outbreaks, rodent reservoirs contribute to long-term disease persistence.
This cross-species dynamic highlights the necessity of accounting for animal populations in long-term management strategies. Incorporating both human and rodent populations supports a One Health approach to disease prevention, aligning closely with United Nations Sustainable Development Goal 3 for Good Health and Well-being and Goal 17 for Partnerships for the Goals.
Coordinating multi-layered responses allows authorities to mitigate immediate transmission while securing long-term disease control, as noted by Prof. Kasbawati.
Because the findings stem from mathematical simulations rather than observation from a real-world intervention program, further research using real-world epidemiological data will help validate the model. Future studies can explore specific control measures targeting rodent populations that drive persistent transmission cycles.
Frequently Asked Questions
What is the main finding of the Hasanuddin University Mpox study?
