Hi ,
Thank you for your query.
Generally cough is not very contagious.
It only spreads though air and is contagious only if the infected particles are inhaled through air.
The time period depends on the infection causing the cough.
Usually it ranges from a few days in viral diseases like flu and can extend upto months in diseases like tuberculosis if left untreated.
If you have any further queries you are free to consult me.
Hope this answers your query.
Have a nice day.
