Need help with DSolve inside Manipulate

GROUPS:
After coming out with this system of equations (see insert) , I have been trying to use Wolfram Mathematica 9.0 to solve the systems and plot the curves using Manipulate so that I can have interactive sliders to manipulate the parameters but I haven't been able to do that.
Please, I need your help with the Coding and Simulation of the Model in Mathematica 9.0.
Please find attached the system of differential equations.

... the manual helps ... it is something like
DSolve[{D[S[t], t] == \[Alpha] - \[Beta] S[t] H[t] - \[Mu] S[t],
  D[H[t], t] == \[Beta] S[t] H[t] - (\[Gamma] + \[Lambda] + \[Mu]) H[t],
  D[T[t], t] == \[Lambda] H[t] - \[Mu] T[t],
  D[A[t], t] == \[Gamma] H[t] - (\[Delta] + \[Mu]) A[t](* initial conditions *)}, {S[t], H[t], T[t], A[t]}, t]
if you must go to numerical solutions (NDSolve[]), the coefficients must be specified ... the I is reserved for the imaginary unit in Mma, so use e.g. H instead of I
