Why the EBOLA press conference today concerns me

I heard the EBOLA press conference while doing my stairclimber. One point that troubles me is when the CDC states that only patients with symptoms can give you EBOLA. If anybody has had microbiology, epidemiology, or pathophysiology courses knows the difference between a sign and a symptom . While signs are objective, symptoms on the other hand are subjective. Signs are called objective in the sense that they can be felt, heard or seen. Bleeding, bruising, swelling and fever are signs. Symptoms are subjective in the sense that they are not outwardly visible to others. It is only the patient who perceives and experiences the symptoms. It is only when the patient experiences certain symptoms that he or she approaches a physician. So what if an infected patient has a fever or nausea or muscle aches BUT he does not really notice these enough to have him register them as symptoms. In OTHER WORDS, an infected patient's symptoms can vary even if the signs and severity of disease are the same in 2 patients. SO AN INFECTED PATIENT MAY HAVE NO SYMPTOMS BASED ON THE SPECIFIC PATIENT!!!!
