Maths Could Help Understand The Spread of Infectious Diseases

Fear of public pathogens may end up driving the wrong type of behaviour if the public's information is incorrect.

Researchers have found that maths could help public health workers understand how human behaviour influences the spread of infectious diseases like Ebola and Severe Acute Respiratory Syndrome (SARS).

Current models used to predict the emergence and evolution of pathogens within host populations did not include social behaviour.

But adding dynamic social interactions to the new model could allow scientists to better prevent undesirable outcomes, such as more dangerous mutant strains from evolving and spreading.

“We tend to treat disease systems in isolation from social systems, and we often don’t think about how they connect to each other or influence each other,” said Chris Bauch, Professor at Waterloo University in Canada.

“This gives us a better appreciation of how social reactions to infectious diseases can influence which strains become prominent in the population,” Bauch added.

In the study, published in the Journal of Theoretical Biology, the team used computer simulations to analyse how the mathematical model behaved under various possible scenarios.

They observed that human behaviour often changes dramatically during the outbreak, for instance, they might start using face masks.

Also, fear of public pathogens may end up driving the wrong type of behaviour if the public’s information is incorrect.

The new modelling could help public responses navigate and better channel these kinds of population responses, the researchers said. (IANS)

As India registered an increase in lifestyle diseases including diabetes and thyroid, a new report suggests that women are unhealthier than men, and Chandigarh is the healthiest city while Kolkata unhealthiest city for the second year in a row. This is the latest health news.

As per the GOQii India Fit Report 2020, diabetes has increased from 7.1 to 12 per cent this year.

“The incidence of diabetes is highest among older adults at 23.81 per cent and seniors at 36.82 per cent. As per the report, 13.5 per cent of Indians have cholesterol issues.

“Currently 36 per cent of the people who have high cholesterol have heart issues too while 51.7 per cent of the people who have diabetes have abnormal cholesterol too. This past year, thyroid issues have increased from 6.8 to 10.7 per cent. The report also suggests that 13.4 per cent of the people in India have high blood pressure,” GOQii, a smart-tech enabled preventive healthcare platform, said.

As per the report, 27 per cent of India has acidity and indigestion issues.

Speaking city-wise, 18 per cent people in Kolkata are diabetic followed by Surat and Bhopal. Kolkata also has the largest aging population in the country, the most people with acidity, and the highest incidence of lifestyle diseases, while Bhopal has the highest percentage of people who consume alcohol.

The report has collected data from a cross-section of 5 million GOQii app users across 16 cities.

Interestingly, it also took the study of longevity under its ambit, and reveals what some of India’s oldest people attribute their longevity to.

Turns out, the secret to a long life is – eating nutritious food, staying active, socializing and sound sleep. These attributes were the common contributing factors for leading a long and healthy life according to 90-year olds and centenarians.

The elderly people also believed that eating home-cooked and fresh, local and seasonal vegetarian meals at fixed and regular intervals played an important role in their day-to-day regimen. Dairy, especially milk, curd and ghee emerged as kitchen superheroes for this age group.

The centurions also believed that having a hobby, being social and content enhanced the quality of their lives. (IANS)
