The Role of Climate Change in Infectious Disease Spread
Climate change is increasingly recognized as a critical factor influencing the transmission and spread of infectious diseases worldwide. Rising temperatures, changing rainfall patterns, and extreme weather events are altering the geographical distribution of pathogens and their vectors, creating new challenges for public health systems. Complex relationship between climate change and the dynamics of infectious diseases, emphasizing how environmental changes are facilitating the spread of both emerging and re-emerging diseases. Warmer temperatures can expand the habitats of vectors such as mosquitoes and ticks, increasing the risk of diseases like malaria, dengue, Zika, and Lyme disease in regions where they were previously uncommon. Changes in rainfall patterns and humidity also influence the breeding sites of these vectors, contributing to an increased incidence of waterborne diseases like cholera and leptospirosis, especially in areas with inadequate sanitation infrastructure. Highlighting how extreme weather events such as floods, droughts, and storms can disrupt healthcare systems, increase the risk of malnutrition, and lead to the displacement of populations, all of which create conditions conducive to the spread of infectious diseases.
