  1. Question 1

    Q1. Dengue fever outbreaks in Punjab in 2023 were linked to which environmental factor that has worsened due to climate change?

    • A) Decreasing winter temperatures disrupting mosquito lifecycles
    • B) Prolonged monsoon rains and stagnant water creating breeding grounds for mosquitoes
    • C) Industrial chemical runoff contaminating water supply systems
    • D) Deforestation reducing natural predators of mosquito populations

    Answer: Prolonged monsoon rains and stagnant water creating breeding grounds for mosquitoes

    Explanation: Dengue fever outbreaks in Punjab in 2023 were strongly linked to prolonged monsoon rains and the resulting stagnant water pools that provide ideal breeding grounds for Aedes aegypti mosquitoes, the dengue vector. Climate change has extended the monsoon season and increased rainfall intensity in Pakistan, expanding the geographic range and seasonal duration of dengue transmission.
