Knowing the Challenge
Throughout history, humans have been challenged by many
different health issues. With the development of vaccines for
many life-threatening and crippling diseases (such as for rabies,
smallpox and polio) and the discovery of antibiotics, humans
have gradually become used to the idea that most diseases
could be prevented or treated. However, in the last two decades
of the 20th century, this false sense of security was shattered by
HIV and Aids.
So how can we meet the challenge posed by HIV and Aids?
This is the question we investigate in Theme 1. We do this by
Structure of Nevirapine
dealing with six basic questions:
Where does Aids come from?
What is HIV and how does it attack the body?
How is HIV transmitted from one person to another and how can we prevent it?
What are the symptoms and diseases associated with HIV infection?
How can HIV infection or Aids be diagnosed?
How can HIV infection and Aids be managed with antiretroviral therapy (ART)?
Each one of these questions will be discussed in a separate learning unit and, in this way, we will start to
suggest possible answers to the Aids challenge.
