With climate change causing a change in the temperatures and seasons of the world, it is causing a change in the conditions of regions that were or were not, at an earlier point, hospitable for humans, animals, pests, and infection carrying bacteria. Bacteria that need warmer climates to live are able to live in regions that were previously too cold. This phenomenon has caused an increase in illnesses in areas that were safe from certain diseases due to their regional advantage. Heat waves and rise in temperature have also led to an increase in the number of deaths caused by heat. The rise in temperature, aided by the lack of proper nutrition and water, has led to an increased death toll in rural regions. The World Health Organisation has already attributed an increased number of heat related illnesses and deaths to climate change and has predicted an increase in the future due to worsening conditions.
