Compared with large enveloped viruses, small naked viruses such as poliovirus are generally

  • A.equally sensitive to drying
  • B.unable to survive outside a host at all
  • C.far more resistant to inactivation
  • D.far more easily inactivated

Answer: C

A naked virion is a protein shell around nucleic acid with no fragile lipid membrane, so it tolerates drying, detergents and solvents orders of magnitude better than an enveloped virus does. That is why lipid solvents inactivate herpesviruses readily but not polioviruses.
