  We calculate second- and fourth-order cumulants of conserved charges in a
temperature range stretching from the QCD transition region towards the realm
of (resummed) perturbation theory. We perform lattice simulations with
staggered quarks; the continuum extrapolation is based on $N_t=10\dots24$ in
the crossover-region and $N_t=8\dots16$ at higher temperatures. We find that
the Hadron Resonance Gas model predictions describe the lattice data rather
well in the confined phase. At high temperatures (above $\sim$250 MeV) we find
agreement with the three-loop Hard Thermal Loop results.
