Viral Immunology

The study of immune responses to viruses is known as viral immunology. The immune system refers to a group of cells and proteins that work to defend the skin, nasal passages, intestinal tract, and other areas against external antigens like microbes (organisms including bacteria, fungus, and parasites), viruses, cancer cells, and poisons.

Viruses are necessary intracellular parasites that rely on their host to support their reproduction and spread to neighbouring cells. Human viral infections rarely cause mortality, despite the fact that they are extremely cytolytic to individual cells.

The study of immunity is beneficial to many medical professions, including rheumatology, virology, allergology (dermatology), bacteriology, cancer, and transplantation medicine.

Immunity is categorized in two types:

• Innate immunity 
• Adaptive immunity 

Medications:
Acyclovir (Zovirax), famciclovir (Famvir), and valacyclovir (Valtrex) are medications used to treat viral infections. They are effective against herpesvirus, especially herpes zoster and herpes genitalis. Ibuprofen and acetaminophen are medications used to treat viral fever.
