Spread of Infectious Diseasessalivasome infections are spread by direct contact with saliva (such as kissing) or indirect contact with contaminated objects (such as children sharing toys/putting them in mouth).
cytomegalovirus infection
glandular fever
hepatitis BSlide13
Spread of Infectious Diseasesperson-to-person spread is raresome infectious disease are almost without exception never spread by direct contact with an infected person. These diseases are usually spread by contact with an environmental source such as animals, insects, water or soil
