an immune response is like a fire

Categories: Comparisons

An example of a simile used to explain a natural phenomenon:

"But even after someone is infected, the host actually mounts, for all these [respiratory] viruses, a really dramatic immune and inflammatory response. So it sort of lights a fire. And even when the virus stops replicating, you know that fire continues to burn, and in a lot of cases that's what lands people in the hospital. And so you want to prevent the virus from igniting that fire, that is what really ends up causing a huge amount of damage to the patient.

…the greatest benefit [of the antiviral drug being tested] is in the outpatient setting before that fire gets ignited."
