Climate change and Infectious diseases

  • Habitat loss forces animals to encroach upon human territory, thus escalate the risk of human-animal interaction and the transfer of pathogens from wildlife to humans.

  • Viruses which do not harm animals can be fatal for humans. Eg Nipha Virus.

  • An analysis of 2022 published in Nature Climate Change warns that humans now face a broader spectrum of infectious agent than ever before.

  • An analysis done by Nature Climate Change in 2022 warns that humans are facing now a broader spectrum of infectious agents than ever before.

  • Half of all-known infectious diseases threatening humans worsen with changing climate patterns.

  •  Diseases often find new transmission routes, including environmental sources, medical tourism, and contaminated food and water from once-reliable sources.

  •  India, in particular, has felt the ominous impact, with early summers and erratic monsoons causing water scarcity across the Gangetic plains and Kerala.

  • The climatic shifts are ending up with severe health crises, including a dengue epidemic in Dhaka (Bangladesh) and Kolkata and the Nipah outbreak in Kerala.

Growing risk posed to global health

  • Globally, there is an obsession with the enigmatic “Disease X”.

  • The WHO declared “Disease X” represents the knowledge that a serious international epidemic could be caused by a pathogen currently unknown to cause human disease.

  • Climate change is not limited to infectious diseases. It also exacerbates injuries and deaths from extreme weather events, respiratory and cardiovascular diseases, and mental health issues.

  • In the face of a changing climate and the growing threat of infectious diseases, protecting ecosystems, fostering collaboration, and embracing the One Health paradigm are our best defenses.
