A skin infection is an infection of the skin in humans and other animals, that can also affect the associated soft tissues such as loose connective tissue and mucous membranes. [ citation needed ] They comprise a category of infections termed skin and skin structure infections (SSSIs), or skin and soft tissue infections (SSTIs), [ 1 ] and acute ...
Molluscum contagiosum (MC), sometimes called water warts, is a viral infection of the skin that results in small raised pink lesions with a dimple in the center. [1] They may become itchy or sore, and occur singularly or in groups. [1] Any area of the skin may be affected, with abdomen, legs, arms, neck, genital area, and face being the most ...

A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [ 1 ] Examples are the common cold , gastroenteritis , corona , flu , pneumonia .
Common infection of the skin or mucosa may affect the face and mouth (orofacial herpes), genitalia (genital herpes), or hands (herpetic whitlow). More serious disorders occur when the virus infects and damages the eye ( herpes keratitis ), or invades the central nervous system, damaging the brain (herpes encephalitis).
The late proteins form the capsid and the receptors on the surface of the virus. Packaging of the viral particles — including the genome, core, and capsid - occurs in the nucleus of the cell. Here, concatemers of the viral genome are separated by cleavage and are placed into formed capsids. HSV-1 undergoes a process of primary and secondary ...
