  We present here continuum extrapolated results for all 2nd order cumulants
using the most recent results obtained by the HotQCD collaboration in
(2+1)-flavor QCD. We constrain the applicability of various HRG models by
presenting a detailed comparison of our results based on different sets of
hadron spectra as well as with virial expansion based model calculations. A
comparison with our lattice QCD results for 2nd order cumulants with models
that parametrize repulsive interactions among baryons and anti-baryons in a
hadron resonance gas through a single excluded volume parameter (EVHRG) is also
shown.
