Programmes designed to control the disease bearing mosquito population have not affected the
incidence of mosquito –borne diseases.

The occupation of the people in a country affects their risk of exposure to mosquito-borne diseases, more than does television watching.

The incidence of mosquito –borne diseases in countries with a high number of television sets per capita is likely to decrease even further.

The more time people in a country spend outdoors, the greater is their awareness of the dangers of mosquito-borne diseases.

The more television sets there are per capita in a country, the more time the average country resident spends watching television.
