Medical History

This week in 1993, two articles in the journal Nature solved a mystery in the development of AIDS: Why do many patients exhibit an early outbreak of HIV virus particles in their blood, but then go as many as 10 years before the virus reappears in their blood? The published reports pointed to lymph tissue throughout the whole body acting as a reservoir to hide the virus during this latent period. The significance of the finding is that to be effective, any vaccine must act to block the virus before it takes hold in the lymph system.

Women generally have less navel fluff because they have finer, shorter body hair.
