The virus doesn't want anything! It just replicates so often that by chance it got the mutation that will trigger a sneeze (in this case) and this mutation is coincidentally the best one to spread the virus itself (because mutation = just an error of the copy of virus DNA/RNA) so it's the mutation that survives and travel hosts and will be the one you will get.
