Bernd Sebastian Kamps is editor of medical textbooks about HIV Medicine and Influenza. The next topic on his priority list is viral hepatitis. Many HIV-infected individuals are coinfected with hepatitis viruses. Coinfection is a concern because:

• in many countries about one quarter of HIV-infected persons are also infected with hepatitis C virus (HCV)

• HCV is one of the most important causes of chronic liver disease in some countries

• HCV infection progresses more rapidly to liver damage in HIV-infected persons

• HCV infection impacts the course and management of HIV infection.

In Free Medical Information, Bernd Sebastian Kamps has described the principles of physicians-published medical textbooks.

Bernd Sebastian Kamps will continue to allocate part of his resources to open access medical textbooks.
