COLDS.. .how long are we INFECTIOUS for?

[noonar]

hi dd1 and i have a stinking cold.

does anyone know how long you are infectious with a cold?

i think you stop being infectious after a certain number of days after symtoms appear, even if you still have symptoms. (did that make sense??)

Im not sure if there any exact signs that you are infection free, but i always think that if you arnt violently coughing and sneezing your ok, the germ is everywhere at the moment so not sure anywhere is infection free!

thanks! we have a few vulnerable people on our 'people to see' list, so want to be careful.
