Local, National and Global Disease Patterns Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

What is meant by a local pattern of disease?

A local pattern of disease is how common a disease is in a small area, such as one town or region.

A national pattern of disease is how common a disease is across a whole country.

A global pattern of disease is how common a disease is in different parts of the world.

Asthma can be more common in areas close to busy main roads with more air pollution.

Malaria is common in many tropical countries but is rare in the UK.

Areas can differ in pollution levels, jobs, housing, and access to health care, which affect disease.

Countries can differ in climate, diet, wealth, and health services, so different diseases are more common.

An epidemic is a sudden rise in cases of a disease in one country or region.

A pandemic is an epidemic that has spread to many countries or worldwide.

Maps can show where disease rates are high or low, using colours or shading for each area.

They use disease patterns to plan health services and target prevention, such as screening or vaccines.

By comparing data from different years, we can see if a disease is rising, falling, or staying the same in an area.
