Causes of Malaria

Question 1

physical - temperature

Answer 1

for mosquitos to survive, the air temperature must be between 15-40 degrees celsius

Question 2

physical - shade

Answer 2

lots of shade available, as mosquitos digest blood in the shade

Question 3

physical - natural disasters

Answer 3

natural disasters like earthquakes and tsunamis disrupt water systems, creating stagnant water for mosquitos to lay larvae

Question 4

physical - stagnant water

Answer 4

stagnant water like lakes, puddles and paddy fields provide places for mosquitos to lay their larvae

Question 5

human - stagnant water

Answer 5

the creation of reservoirs creates more stagnant water for mosquitos to lay larvae

Question 6

human - lack of investment

Answer 6

lack of investments in sanitation, healthcare and education means that people are unaware of causes of malaria and cannot access treatment

Question 7

human - poorly managed irrigation

Answer 7

if irrigation systems are not managed correctly, this can lead to the pooling of water

Question 8

human - bomb craters

Answer 8

in Vietnam, bomb craters have created thousands of pools of stagnant water and have burst sewage and water pipes

Question 9

human - clearing forests

Answer 9

as many mosquitos live in the shade of the forest, clearing forests puts people in contact with mosquitos, causing malaria to spread

Question 9

human - migration

Answer 9

migration leads to the creation of shanty towns, which, especially in marshland, provide perfect conditions for mosquito breeding

Question 10

human - paddy fields

Answer 10

an increase in the amount of paddy fields to provide for the growing population provides more space for mosquitos to lay larvae

Question 11

human - mines

Answer 11

the creation of mines creates more areas for water to pool

Question 12

human - poor healthcare

Answer 12

poor healthcare and a lack of trained staff means that malaria often cannot be treated

Question 13

human - lack of money

Answer 13

poorer people cannot afford nets to protect from mosquito bites

Question 14

human - government

Answer 14

in some developing countries, the government cannot afford drugs to treat malaria

Question 15

human - mother to child transmission

Answer 15

due to a lack of education on how malaria is transmitted and the proximity between mother and child, malaria is often passed from mother to child

Question 16

human - exposure of skin

Answer 16

in hot countries, the exposure of skin allows mosquitos to bite and potentially transmit malaria
