Educate people = taught to prevent diseases Produce more food Improve healthcare facilities Improve sewage systems Provide clean water
Why are infectious diseases less common in developed countries ?(3)
Clean environmental conditions
High quality healthcare facilities
Improved health education

A deadly blood disease spread by infected mosquitoes.
What the human factors that cause malaria ? (4)

Poor sanitation in shanty towns can contribute to areas of stagnant water.
Settlements provide large populations for blood meal.
