Viruses are very simple organisms that rely on the host cell's biochemical machinery for sugar metabolism and protein synthesis- they are commonly described as 'obligate intracellular parasites.'
Antibiotics cannot treat viral infection. While anti-viral therapies do exist, they are costly and often ineffective. The alternatives, therefore, include '''vaccination''' (priming the immune response to create memory lymphocytes for a particular virus) or '''eradication'''.
