Study: The strengths of economics and physics make it harder to prevent illness – (Details)



Why is the number of people getting the vaccine raised? How does a strong anti-vaccine resistance work when a preventative disease causes a disease?

A recent study by Dartmouth College shows that vaccine-backs can create a phenomenon called Hysteresis, creating a negative history that has strained the public anti-vaccination resolution. The discovery explains why it is so difficult to increase growth, although weak evidence indicates that vaccines are safe and beneficial.

The loop of a hysteria is affected by the force that it observes after the force itself has been eliminated. That is why unemployment rates continue to be an economic recovery event. Therefore, physical objects return to their original state after acting outside the forces. And, according to Dartmouth, the people rescind the anti-vaccination campaigns like ordinary flu.

"Taking into account all the benefits of vaccination, it is a struggle to understand why vaccinations can continue to be low levels of severity," said Feng Fu, assistant professor of mathematics at Dartmouth College. "They are issues of history, and we now know that the story is the answer."

Research, published in the journal Processes of the Royal Society BIt is the first investigation to prove that hysteria can impact public health.

"Once they question the safety or efficacy of the vaccine, it is very difficult to overcome negative associations. Hysteresis is a powerful force that can not be complicated by humble levels of society," said Fu, a leading researcher.

The low vaccine rule may prevent "immune disease" and may lead to the spread of infectious diseases. In Europe and North America, illnesses such as illnesses, mosquitoes, ghosts and pertussis in childhood have been returned due to insufficient vaccination coverage.

Previous studies have combined with behavior patterns with epidemiology to understand the challenge of voluntary vaccine, but could not fully explain the sustainability of the minimum vaccine requirement. The Dartmouth study specifically examines the latest vaccination problem that can lead to vaccination decisions and future vaccinations.

"This study shows why it is so difficult to reverse the low or decreasing vaccination level," said Xingru Chen, a Dartmouth graduate and first researcher. "The objective and objective logic of public health is not enough to overcome hysteresis and human behavior."

According to the research, hysterectomy can be caused by uncertainties about vaccine risk and efficacy. Population-related experiences or negative perceptions make a tendency over time, amongst the "vaccine paths" stuck in the eyes of hysteresis.

Hysteresis does not stop vaccination, although negative objections have been eliminated, so that society's illness is increasingly vulnerable.

"At the level of vaccination, the past is predicting the future, unfortunately, it means that many people are suffering so much as not to find a way to break the negative impact of the hysterical look," said Fu.

The study includes an example of the United Kingdom and Welsh pertussis vaccine between the period from 1978 to 1992. He has been working for 15 years to recover the "cough cough" from 30 to 91%. According to the research group, this recovery would only happen in the area around the year.

In the study, the fluctuations in mosquitoes slow down the growth of the vaccine. In some countries, like France, hawthorn has become an endemic disease even if it is an effective vaccine.

According to the study, "The measles vaccine coverage has gradually increased, but it has not yet been enough, after more than a decade against the MMR vaccine and autism."

"It's possible to lower the population's vaccine levels rapidly, but hysteresis can lead to the recovery of its population over many years," Chen said.

According to common flu, research suggests that the vaccine should have an efficacy of more than 50 percent to achieve a high level of vaccination, to reach a level that is difficult for the disease to reach the mutation rate.

Hysteresis effect identified by vaccination, research groups, public health officials, can design campaigns that increase voluntary vaccine rates, especially by promoting the vaccine, as an altruistic attitude to moral and social norms.
