Herpesviridae

Herpesviridae is a large family of DNA viruses that cause diseases in animals, including humans. The members of this family are also known as herpesviruses. The family name is derived from the Greek word herpein ("to creep"), referring to the latent, recurring infections typical of this group of viruses. Herpesviridae can cause latent or lytic infections.

Structure

At the core of the herpesviridae structure is a relatively large double-stranded, linear DNA genome encased within an icosahedral protein cage called the capsid. The capsid is surrounded by a lipid bilayer called the envelope. The envelope is joined to the capsid by means of a tegument. This complete particle is known as the virion.

Classification

Herpesviridae can be classified into three subfamilies: Alphaherpesvirinae, Betaherpesvirinae, and Gammaherpesvirinae. Each of these subfamilies contains different genera based on their biological properties.

Diseases

Herpesviridae can cause a number of diseases in humans, including herpes simplex, varicella zoster, cytomegalovirus, and Epstein-Barr virus. These diseases can range from mild to severe, and can even be life-threatening in immunocompromised individuals.

Treatment

Treatment for herpesviridae infections often involves antiviral medications. These medications can help to reduce the severity and frequency of symptoms, but they cannot cure the infection.

Prevention

Prevention of herpesviridae infections can be achieved through the use of vaccines, safe sex practices, and avoiding close contact with individuals who have an active infection.
