Research believes that humans are creating conditions that may lead to the next pandemic-Scientific Exploration-cnBeta.COM

New research from the University of Sydney has found that humans are creating or exacerbating environmental conditions that may lead to the next pandemic of infectious diseases.Modeling by the Sydney School of Veterinary Medicine shows that ecosystem pressure, climate change, and economic development are key factors related to the diversification of pathogens (pathogenic factors such as viruses and bacteria). This may lead to the next outbreak of infectious diseases.

The research report of Dr. Balbir B Singh, Professor Michael Ward and Associate Professor Navneet Dhand was published in the international journal “Transboundary and Emerging Diseases”. They found that in high-income countries with larger land areas, denser populations, and higher forest coverage, zoonotic diseases (disease spread between animals and humans) are more diverse.

The study also confirmed that population growth and increased density are the main driving factors for the emergence of zoonotic diseases. The global human population has increased from about 1.6 billion in 1900 to about 7.8 billion today, putting pressure on the ecosystem. As the human population increases, so does the demand for housing. To meet this demand, humans are encroaching on wild habitats. This increases the interaction between wild animals, domestic animals and humans, which increases the possibility of bacteria and viruses being introduced into humans from animals.

So far, this disease model is still very limited, but this information can help provide information for the alleviation of the disease, and may prevent the next pandemic disease from appearing. Other zoonotic diseases that have recently devastated the human population include SARS, avian flu (H5N1) and swine flu (H1N1), Ebola and Nipah viruses.

The researchers also pointed out that weather variables, such as temperature and rainfall, may affect the diversity of human diseases. At higher temperatures, there tend to be more new pathogens. The combination of these factors confirms that human development, including human-influenced climate change, not only destroys our environment, but is also responsible for the emergence of infectious diseases, such as COVID-19. Analysis shows that sustainable development is not only essential for maintaining ecosystems and mitigating climate change, it can provide information for disease control, mitigation or prevention.
