Hepatitis A and hepatitis E viruses are transmitted by water contaminated with feces (fecaloral route), produce acute infections and do not induce a chronic carrier state. Ebola is a viral hemorrhagic febrile disease that can cause death in 25days. Ever forget a toothbrush and borrow your partners? The severe acute respiratory syndrome (SARS) corona virus, the etiological agent of a highly lethal type of pneumonia, was detected in the saliva of each SARS patient studied, and was present in quantities up to 6.38108copies/ml (203). When the DNA or RNA affects the host cells genes, it can push the cell toward becoming cancer. Epidemiology of nonkeratinocytic skin cancers among persons with AIDS in the United States.

Yes, you have a dirty mouth. Although present in saliva (150), influenza virions may not be infectious because of the antiinfluenza virus activity of salivary glycoproteins (207). In humans, HTLV-1 is spread in the same ways as HIV, such as unprotected sex with an HTLV-1-infected partner or injection with a needle after an infected person has used it. Some viral diseases in tropical and subtropical parts of the world are acquired through insect bites.

Oral detection of EBV DNA may require both salivary and subgingival sampling, Salivary samples of 33 systemically healthy periodontitis patients, 2568years of age. The EpsteinBarr virus infects Blymphocytes, which gives rise to the strong Tlymphocyte response that is characteristic of mononucleosis. The longer the subjects had resided in the USA, the greater the decrease in detection of A.actinomycetemcomitans orally (OR 0.82). Parenttochild transmission of A.actinomycetemcomitans took place in 6/19 (32%) families, whereas P.gingivalis was not transmitted from parent to child in any of the families studied (17).
