Climate change is increasing temperatures, precipitation, and sea levels according to indicators like rising CO2 levels, temperature records, and melting ice. This is enhancing transmission of infectious diseases by expanding the habitats of disease-carrying vectors and exposing more humans to vector-, zoonotic-, and waterborne diseases. The World Health Organization warns that vector-borne diseases are changing geographically rapidly due to climate change combined with factors like intensive farming, deforestation, urbanization, and increased travel.

• Deforestation
• Population
• Rapid unplanned urbanization
• And increase international travel and trade.
