Unscramble the Blue Letters
During the first stage of HIV infection, the virus replicates within helper T cells, destroying many of them in the process. During this stage, patients often experience flu-like sopymmts, but are typically not yet in mortal deganr. However, for a period ranging from a few months to several years, during which time the patient may look and feel completely healthy, the virus ctioennus to replicate and doertsy T cells. When T cell ctuons drop too low, patients are in serious danger of contracting deadly infections that healthy iumnme ssmyets can normally handle. This stage of HIV infection is known as AIDS.

Original Text
During the first stage of HIV infection, the virus replicates within helper T cells, destroying many of them in the process. During this stage, patients often experience flu-like symptoms, but are typically not yet in mortal danger. However, for a period ranging from a few months to several years, during which time the patient may look and feel completely healthy, the virus continues to replicate and destroy T cells. When T cell counts drop too low, patients are in serious danger of contracting deadly infections that healthy immune systems can normally handle. This stage of HIV infection is known as AIDS.
