Know How Math Predicts Human Behaviour

Washington D.C. [USA] Aug 19 (ANI): Seems like math can predict human behaviour in reference to the emergence and evolution of pathogens within host populations.

According to a study from the University of Waterloo, mathematics can help public health workers understand and influence human behaviours that leads to the spread of infectious disease.

The researchers treated disease systems in isolation from social systems which gave them a better appreciation of how social reactions to infectious diseases can influence which strains become prominent in the population.

By adding dynamic social interactions to the models already used for disease outbreaks and evolution, researchers could better anticipate how a virulent pathogen strain may emerge based on how humans attempt to control the spread of the disease. This new addition to disease modelling could allow scientists to better prevent undesirable outcomes, such as more dangerous mutant strains from evolving and spreading.

The social modelling could impact public health responses to emerging infectious diseases like Ebola and Severe Acute Respiratory Syndrome (SARS). Human behaviour during these outbreaks often changes dramatically during the outbreak. People may start using face masks, or stop using them prematurely. Also, public fear of the pathogens may end up driving the wrong type of behaviour if the public's information is incorrect.

Researchers formulated the new mathematical model to study the influence of social behaviour on the competition between pathogen strains with different virulence. Using computer simulations, they analyzed how the model behaved under various possible scenarios that might occur to populations to explore the logic of the hypothesis that social behaviour plays a role in the evolution of the strain.

Human behaviour plays a big role in the spread and evolution of an infectious disease.

The findings appeared in the Journal of Theoretical Biology. (ANI)
