These range from mild sprains and lacerations to joint dislocations, broken bones and severe neck or head injuries. Trampoline deaths are rare, but they do occur. Most trampoline injuries occur in ...
Figure 1. Early Symptoms of HIV. The stages of HIV infection are acute infection (also known as primary infection), latency, and AIDS.
