Reason why some of our kids never get sick...?

Superinfection exclusion is the ability of an established virus

infection to interfere with infection by a second virus.

There's infection and then there's superinfection – when a

cell already infected by a virus gets a second viral infection. But some

viruses don't like to share their cells…. " A virus can

interfere with a secondary infection in a variety of ways, " says

Rice, head of the Laboratory of Virology and Infectious Disease and the

Maurice R. and Corinne P. Greenberg Professor. " It can interfere

with how a virus attaches to the cell, its penetration, or its access to

the cell's resources. " If both viruses are competing for the

same resources in the cell, then the first virus can confiscate them so

none are available for the second virus.
