its not recommended unless there is difficult situation, anyway there is Assalamu aleykum and it doesnt require handshaking.

and in Somalia its often that man doesnt shake hands with opposite sex or the man or the women covers their hand with some cloths,

this also involves prayer, because when Muslim washes for prayer if he touches the opposite sex's body he has to wash again except for some of the family members.
