What causes a fever? Bacteria or virus? I know its a germ that causes sickness but what causes a fever, bacteria or virus? .

Both: Bacterial and viral infections can cause fevers, in fact they are hallmark symptoms. Viral fevers tend to be lower grade as a rule, and bacterial higher. It is one way the body fights back, by basically "cooking" the pathogen in an attempt to kill it off. The mechanisms are too lengthy to describe here, but the answer is both. ...Read more

If you are running a fever of 101 an not sure if its its caused by bacteria our virus, should you wait out before calling the doctor?

Depends: It greatly depends on what the other symptoms are. If it is just fever, it is reasonable to wait; if it is fever and a viral syndrome such as congestion, body aches, and maybe sore throat, then yes, wait. If there is a focal problem, you should add that so we can comment whether it needs to be evaluated immediately. ...Read more

I had a bacterial virus and fever them led to step throat won't seem to go away after a week, now I'm noticing a lump on my neck. What's going on?

Mononucleosis?: How were you diagnosed with strep throat? If you took a course of Amoxicillin the symptoms should be gone by now. It is possible you were misdiagnosed and are suffering from infectious mononucleosis which routinely resolves on its own. If the swelling gets larger or becomes painful see your primary doctor as soon as possible. ...Read more

My son has running a very low grade fever for 4 days. No cold viruses bacteria. Pale stool which now had blood in it and his resting heart rate is 114-128. He is irritable and mood swings. Doc isn't take this seriously. Should he?

Follow up suggested: He may have an infection which is related to both the low grade fever, blood in the stool and change in stool color.
Fever can elevate heart rate.
Probiotics (ages four months and older) such as yogurt and keeping him well hydrated can help.

Can a e. Coli colony contain flu viruses or other viruses inside the bacteria?

Can a e. Coli colony contain flu viruses or other viruses inside the bacteria?

Not exactly: You're right to prompt the question, in that bacteria can be made more virulent by uptake of "signals" from a bacteriophage. Also, an e.Coli infection does not preclude a superimposed or secondary viral illness--which together compromises the host patient more than a single infection might. However, flu viruses can not live within e.Coli. ...Read more

Can anti-bacterial soap help fight the swine flu virus?

Not really: If you are referring to the present scare, this reported flu strain has only been associated with pig to human transmission, not human to human transfer.

What I would like to point out here is the "news press" and it's affinity to blow things out of proportion and only report what will get ratings. Talk to docs. ...Read more

What are the risk of Endocaditis if you have had a heart Valve repair few yrs ago and you have a fever, stomach gasteronteritis or Virus with Fever GP says I have risk and this can all lead to it, how true is this? Is the Bacteria in the Blood? Ideas

Low risk: The bacteria that cause intestinal infections are uncommon causes of endocarditis. No risk from viruses. Elevated risk depends on the kind of valve repair done, whether you have an artificial valve, etc. Increased risk is primarily from respiratory, skin, or dental infections -- and even with these, the actual risk of endocarditis is very low. Discuss with your cardiologist or cardiac surgeon. ...Read more

How we differentiated cough by virus or by bacteria only on clinical symptom?

Not easy: There must be an evaluation of symptom intensity (bacterial usually worse and can be life-threatening and fast evolving). X- rays can help rule out bacterial. A blood white cell count will usually be low or normal with viral. A sputum culture taken to grow out pathogenic bacteria is quite definitive. Viral - itises are usually self-limiting, and antibiotics do not affect viral conditions. ...Read more
