The NA62 experiment at CERN SPS designed to measure the branching ratio of the ultra-rare
$K^+ \rightarrow \pi^+ \nu \bar{\nu}$ decay using a decay-in-flight technique, collected data from 2016 to 2018. The
analysis of the full 2018 data set is presented here, corresponding to a total number of kaon decays
of about $2.62\times10^{12}$ , the largest data set so far collected. The combination with 2016-2017 data
set is also reported. In addition the latest results from other searches are briefly presented.
