The risk of human-to-animal transmission in animals in the western US has increased since 1950 due to climate change, new. learning they find. Most importantly, this study provides valuable insights into how the deadly disease progressed in the US, which can help us understand more about its future.

“We want to understand where the epidemic (yes, the ‘plague,’ which is still a common wildlife disease) can exist in the United States, where it may have changed in the last century, and why the epidemic may have occurred in those areas. it does, not to mention a 20-mile distance, “said study author Boris Schmid in an email.

Yersinia pestis and the bacteria that cause the plague — including that plague, Black Death, which killed around 25 million people for four years in the 1300s. The bacteria are transmitted to humans from animals, especially rats, which carry the fleas of the plague. Scientists say that the epidemic, like many other infectious diseases, will likely increase the spread of human encroachment as the earth warms and that humans become more closely associated with wildlife.

But there is not much research out there on what history and conditions are best for the epidemic to emerge and get out of control. As a result, there are still many important questions about the epidemic — such as why it has not spread to other parts of the world, or why human affairs do not correspond to where animals carry the disease — that remain unanswered.

Most modern information on how infectious diseases can be spread by climate change is based on the so-called biodiversity, or indications of how wildlife habitats can grow and adapt. Such a species contributes to the spread of disease by ignoring many important aspects of how bacterial bacteria interact with the environment, combining such factors as the type of soil and their uptake, which may help to tell good stories about animal-to-human transmission, and why epidemics occur. ‘one place and not another.

“Surprisingly, much of what we know about climate and disease comes from future sources, but we do not know much about the latest,” said co-author Colin Carlson on Twitter DM.

The authors of the study endeavored to find a better approach to this issue. Using a wide range of historical data, including animal serology tests, epidemiological records, climate records, and soil records, researchers set out a model to look at relationships between datapoints that could accurately describe conditions. which promotes the development of the disease and how it changes over time. Their results were published Friday in Global Change Biology.

The study found that rat areas in some elevated areasns were 40% more likely to contract the disease, which researchers say was due to the heat since 1950. This means that the risk of the plague from transmitting the virus to humans increased, albeit slightly.

“It’s a big, confusing, twisted system, and there are many natural remedies for the disease,” Carlson said. “But as we begin to realize the big picture, we can look at how big changes have taken place since 1950, and they are visible – much of the region is beginning to resemble the conditions that allow epidemics on animals, and more importantly, to make human jumps.”

Just because there is a high probability that a pandemic could occur due to climate change does not mean that you should start worrying about the second coming of the Black Death. Nowadays, it is a good cure for modern antibiotics – but not what you want to put many people at risk for.

“The epidemic is probably the lowest level of concern, compared to the threat of forest fires and other, while the western US is warming up,” Schmid said. “If you sleep in a place where you have not been bitten by fleas, then you have cleared the way for the disease.”

But this research has implications for other types of disease – as well as a dangerous look at our future. One important point: this study shows only calculations man pandemic cases reduce the prevalence of the disease in remote parts of the western US

“I think we are probably ignoring how climate change could affect human and animal health,” Carlson said. “There is a common sense that the main effect should be due to heat and disaster, and I do not think it is a definite thing – I think it is difficult to recreate the weather mark of the infectious disease, because it is small. Very difficult in nature. recurring themes can have far-reaching consequences. ”
