Question

Which combination of prevention measures is most appropriate for controlling vector-borne diseases?

Options

• Safe injection practices and wound care

• Disinfection of blood products and screening

• Eliminating mosquito breeding sites and fly control

• Isolation of infected persons and safe sexual practices

Answer 1

Vector-borne diseases require control of the insect or animal vectors, not isolation of patients. Eliminating breeding sites for mosquitoes and controlling fly populations reduces vector populations, thereby interrupting the transmission cycle of diseases like malaria and dengue.
