A 5-year-old girl becomes very ill after a bacterial infection. She was found to have toxic shock due to exposure to bacterial superantigens.

The major impurity brought about by human sexuality is collectively known as janaba. It should be noted that Islam does not consider sexuality as evil in any way.
