viral diseases
Pathogen-caused infectious conditions
Viral diseases are illnesses caused by viruses—infectious agents that replicate inside living cells.
The term covers everything from common colds and flu to HIV, hepatitis, and COVID-19.
Unlike bacterial infections, viral diseases don't respond to antibiotics: Antibiotics won't help; it's a viral disease.
Treatment typically addresses symptoms while the immune system fights the virus.
