In this paper, we study local uniform continuity of nonnegative weak solutions to degenerate diffusion-drift equations in the form [ u_{t} = Delta u^{m} +
ablacdot left( B (x,t) , u
ight), quad ext{for } m geq 1 ] assuming a vector field $B in L^{p}_t L^{q}_{x}$. Regarding local Holder continuity, we provide a sharp condition on $p$ and $q$, which is referred to as the subcritical region. In the critical region, the divergence-free condition is essential to providing uniform continuity which depends on the modulus continuity of $B$.
