Where did you go on holiday? Hasn't anyone mentioned you should get checked up if you get ill after coming back from holiday?
For general information I would suggest reading this (it's old but still good)
Exercising while sick
There is a lot of information there perhaps the most important is -
"You should never exercise when you have a temperature of 99.5 [degrees] F or above. Working out when you have a fever can cause your body temperature to rise even higher, potentially leading to heatstroke, according to sports-medicine specialist Lewis G. Maharam, M.D."
I don't want to post too much more from the article, but enjoy the read
One item not really covered is the possibility of viral damage to your heart; which can have a debilitating effect on the heart muscle and weaken it, potentially resulting in death.
Exercise Benefits and Prescription By Stephen R. Bird, Andy Smith, Kate James states:
"It is unwise for anyone to exercise whilst suffering from basic viral infections such as influenza... medical evidence would suggest that if a person infected with a virus attempts to exercise the virus can cause a greater amount of inflammation, and even permanent damage to body tissues. Of greatest concern in this context is the possibility of the virus affecting the heart and causing pericarditis, which can cause permanent damage."
Google Books
Edit: More info
Pericarditis
My advice would be that if you want to exercising whilst not feeling the best: Take it easy

I would say rest as you wont have all of your strength. Thus you could either hurt yourself by trying to do what you normally do and/or prolong your cold as your body is now putting effort into healing the muscles instead of fighting your cold.
I just got over a week long cold and took a week off from from the gym. It's amazing how much more strength you will have when you take a week off and let yourself fully heal.
Very strenuous exercise will actually weaken your immune system!
