Common viral infections - clinical features, diagnosis and management 1 MED4MIN.com Medicine Made Easy Education
"Viral infection: Infection caused by the presence of a virus in the body. Depending on the virus and the person's state of health, various viruses can infect almost any type of body tissue, from the brain to the skin. Viral infections cannot be treated with typical antibiotics (antibacterial antibiotics); in fact, in some cases, the use of antibacterial antibiotics may cause side-effects that complicate the viral infection." - MedicineNet definition

Viruses are non-living chemical entities. They are parasites of living cells and can replicate only within living cells by using the cell’s enzyme systems. They have nucleic acid genomes, either DNA or RNA, but not both.

Viruses have a narrow range of cells that they can infect but all or nearly all organisms can be infected by multiple kinds of viruses. There may be as many as 1×10^12 kinds of viruses.

The morphology of viruses is diverse but all have a nucleic acid core surrounded by a protein coat (capsid).

In this educational post, we will present some of the most common viral infections that affect multiple organs.
