Out break in Pakistan
Causes • Unplanned urban overpopulation of areas
• Inadequate housing and public health systems
(water, sewerage and waste management)
• Poor vector control, e.g., stagnant pools of water for
mosquito breeding
• Climate change and viral evolution
• Increased intl travel (recreational, business or
military) to endemic areas
