If only one person is there to see the doctor, why would the doctor prescribe medicine even for his family members who are not there?
Unfortunately, both of these are pretty contagious conditions. FA mentions that scabies spreads via skin to skin contact, and goes on to mention that you're supposed to treat close contacts. I think in this scenario it's ok to give permethrin to the family members who are not present but affected (it's also non-prescription in some cases, I believe.) Slightly related note, similar to why you would treat the sexual partner of someone with chlamydia/gonorrhea, or close contacts of someone with n. meningitides infection.
