Climate change could exacerbate more than 200 human diseases

The feeling that many must have is that we are living the famous “pests of Egypt” with the emergence of many diseases, right? In addition to continuing to face the Covid-19 pandemic, we now have an outbreak of monkeypox, and in some places, such as the UK and the US, a resurgence of the polio virus – all of which are already known to humans.

However, I regret to say that apparently things may not get better. On the contrary, it tends to get worse. According to one A study published in Nature Climate Changemore than 200 human diseases that could be exacerbated and exacerbated by climate change on the planet.

as revealed by the edgeResearchers have long known about the effect of climate on the spread of disease. Warmer temperatures, for example, can make areas again hospitable to disease-carrying mosquitoes, or more frequent storms can carry bacteria into their water waves.

The paper looked at 375 documented infectious human diseases and looked at any climate changes that might interact with them. Among them, the results showed 218 injuries (more than half) that could be exacerbated by interactions such as heat waves, sea-level rise and wildfires.

The research also revealed four main ways climate change affects disease:

1. First, problems arise when changes bring disease-carrying animals closer to humans. For example, animal habitats are affected by things like wildfires that push bats and rodents into new areas, increasing the potential for diseases like Ebola to be transmitted.

2. Climate change also increases the likelihood of viruses passing from animals to humans, as happened with the coronavirus that causes Covid-19. It is also possible that this phenomenon contributed to the Zika outbreak of 2016. In the same vein, cholera and Lassa fever have also been linked to human infection following storms and floods.

3. Third, climate risks lead to pathogens—like how disease-carrying mosquito populations grow in warmer temperatures.

4. Sudden changes in climate make people’s systems less able to deal with disease. For example, large temperature differences can weaken the human immune system, which can be the cause of influenza outbreaks.

The study warns (among many other things) of the visible changes in climate we are seeing, which can be used in public policy debates and discussions in favor of the environment.

For those who would like to know more details, in a comprehensive and flawless work, the team of researchers has also created an interactive graph that shows a specific climate change and its health reactions. Check out the work here.
