An upper limit on the branching ratio of the decay {ital K}{sup +}{r arrow}{pi}{sup +}H, {ital H}{r arrow}{mu}{sup +}{mu}{sup {minus}} is set at 1.5{times}10{sup {minus}7} at the 90% confidence level, for a Higgs-boson mass in the interval 220{lt}{ital m}{sub {ital H}}{lt}320 MeV/{ital c}{sup 2}. In addition, 90%-confidence-level upper limits on the branching ratios of the decays {ital K}{sup +}{r arrow}{pi}{sup +}{mu}{sup +}{mu}{sup {minus}} and {ital K}{sup +}{r arrow}{mu}{sup +}{nu}{mu}{sup +}{mu}{sup {minus}} are set at 2.3{times}10{sup {minus}7} and 4.1{times}10{sup {minus}7}, respectively.
