a)infectious diseases can spread through-
the air,
from direct or indirect contact with another person (including from a mother to her unborn child),
soiled objects,
skin or mucous membrane,
saliva,
urine,blood and body secreations,
sexual contact,
contaminated food and water
b)Vector-borne diseases are infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies.examples-malaria,dengue fever,chikungunia,yellow fever etc.
The prevention and control of malaria can be prevented through the following ways:
1.Controlling mosquito breeding;
2.Preventing mosquitoes from biting people;
3.Killing adult mosquitoes before they bite people;
4.Killing malaria parasites in the blood before they can cause malaria. This is referred to as chemoprophylaxis;
5.Early diagnosis, timely and adequate treatment of all Malaria cases.
