If you're worried, I suggest you get it test :)
Open type of tuberculosis(Cavitatory) are the main transmitting type but the others like lymph nodeTB there is little risk. Also remember that host resistance also plays an important role. If you have goor resistance or immunized with BCG you would be well protected.On the whole you need not worry.
But cos the hospital didn't ask them to check then should there be a problem?
Hi Jessica - you should contact your doctor and get a test to make sure you haven't been exposed. Your friend also should be talking with someone at the hospital to see what the risks are.
