More dogs are put down because of problems due to lack of socialisation than ever die from catching anything, so provided you take obvious precautions (like not taking it to the local park) then I would say take the pup out and about with you, carrying it where there are any other dogs but letting it down if you can find a field or open area.
The more it learns now the easier it will be, get lots of people to make a fuss of it and get it used to the car. Use titbits to get its attention nd reward it if it comes to you and make it sit for its food, by lifting the bowl up above its head its bum will go down and you can tell it sit. Take it out for a wee every time it wakes up, eats, or has been playing for about fifteen minutes, stay out with it till its been, and the do the loopy dance when it does a wee or a poo outside, telling it what a clever baby it has been. Loads of praise and make it fun, and you will find it is keen to please and will soon learn to ask to go out.
