We derive constraints on Wilson coefficients of dimension-six effective operators probing the b -> s transition, using recent improved measurements of the rare decays B-s -> mu(+)mu(-), B -> K mu(+)mu(-) and B -> K*mu(+)mu(-) and including all relevant observables in inclusive and exclusive decays. We consider operators present in the SM as well as their chirality-flipped counterparts and scalar operators. We find good agreement with the SM expectations. Compared to the situation before winter 2012, we find significantly more stringent constraints on the chirality-flipped coefficients due to complementary constraints from B -> K mu(+)mu(-) and B -> K*mu(+)mu(-) and due to the LHCb measurement of the angular observable S-3 in the latter decay. We also list the full set of observables sensitive to new physics in the low recoil region of B -> K*mu(+)mu(-).
