A viral infection caused by Paramyxovirus, a single-stranded RNA virus. Common symptoms include fever, headache and bilateral or unilateral parotitis (swelling of the parotid gland on one or both sides of the face). The parotid gland is usually swollen and tender. Parotid swelling usually occurs 16–18 days after exposure to the virus.
Salivary gland dysfunction affects the flow, amount, or quality of saliva produced. A reduced salivation is termed hyposalivation.Hyposalivation often results in a dry mouth condition called xerostomia, and this can cause tooth decay due to the loss of the protective properties of saliva.
It may also be sexually transmitted, including contact with saliva, such as kissing and mouth-to-genital contact . [6] The virus tends to reside in the trigeminal ganglia . This species appears to be particularly damaging to the nervous system, and some research has attributed Herpes simplex virus 1 infection to an increased risk of developing ...
DNA-templated transcription, with some alternative splicing mechanism, is the method of transcription. Translation takes place by leaky scanning. The virus exits the host cell by nuclear egress, budding, and microtubular outwards viral transport. Human and mammals serve as the natural hosts. Transmission routes are sexual, contact, and saliva.

HIV-SGD is more prevalent in HIV positive children than HIV positive adults, [4] at about 19% and 1% respectively. [1] Unlike other oral manifestations of HIV/AIDS such as Kaposi sarcoma, oral hairy leukoplakia and oral candidiasis, which decreased following the introduction of highly active antiretroviral therapy (HAART), HIV-SGD has increased.
Digestion: Saliva contains amylase, which hydrolyses starch into glucose, maltose, and dextrin. As a result, saliva allows some digestion to occur before the food reaches the stomach. [30] Taste: [31] Saliva acts as a solvent in which solid particles can dissolve and enter the taste buds through oral mucosa located on the tongue. These taste ...
Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
It has also been defined as increased amount of saliva in the mouth, which may also be caused by decreased clearance of saliva. [ 4 ] Hypersalivation can contribute to drooling if there is an inability to keep the mouth closed or difficulty in swallowing (dysphagia) the excess saliva, which can lead to excessive spitting.
