You have an immune system that is supposed to stop viruses from infecting your body. So how do HIV and other diseases outsmart the body's immune system? What can we do to prevent HIV and other diseases from infecting our bodies? Why can't medicines cure HIV, but they can cure other illnesses?
Just because human immune systems cannot get rid of HIV, they still help people clear viruses and bacteria every moment of every day. How does the immune system remove dangerous diseases from our bodies? How can we improve our immune system's response to disease?
Your immune system is one of the most complex and interesting systems in your body. Consider the above questions as you read about the amazing ways that immune systems respond to diseases and also how they are limited by dangerous diseases, like HIV.
