How does the aids virus affect us in the beginning of the disease?

Very variable: Aids disease progression is extremely variable in individuals ranging from rapid progression to death in a year to a decade or more of asymptomatic infection. This variability appears to be affected by other comorbidities, genetics, virus strain, etc.

You may not notice: Most people, after recovering from primary infection (acute retroviral syndrome), have no symptoms for at least a few years. However, they are not normal. Their t-helper cell counts are usually declining, and they have higher levels of immune acttivation and inflammation. Most people have fairly advanced disease by the time symptoms appear, though there are a few conditions that can occur earlier.
