Answer

I HAVE A COLD = I have an illness that involves sneezing, a runny nose, coughing, etc. which often lasts for about a week.

Ex: I had to stay home from work because I had a cold.

I AM COLD = The temperature is lower than is comfortable for me.

Ex.  I forgot my jacket today, so I am cold.

Answer

"I am cold" is about your personal temperature. "I have a cold" is the English equivalent to "estou resfriado" in Portuguese.
