If you mean, go into an office with others, no – not until symptoms have started to recede, 2-3 days after the realization "I've got a cold".
For as long as there are residual symptoms – nasal draining, coughing – I try to be extra vigilant about hand-washing and hand contact with shared surfaces.
Don't go to work -- you'll get everyone there sick. Work at home and be more productive than you would have in the office and no one will hold it against you.
