Super interesting finding.
Imagine the viral infection proceeding with millions of new viral particles each trying to bind and essentially sequestering a molecule of linoleic acid.  It would induce "instant" linoleic deficiency in the infected person.  Research studies have already established that low dietary intake of omega-3 fatty acids and linoleic is a novel reversible risk factor for chronic inflammation. This means low linoleic acid exasperates chronic inflammation.  So it seems you want to add more linoleic acid and to your diet to reduce this risk factor.
