our body eliminates virus without medicine. but antibiotics are needed to rid of bacteria. why?

Answer 1

First of all, our bodies never get rid of a virus or viral infections. In fact, if you have had a virus, such as measles, they can draw your blood and test for it and see that you have had it. Our bodies develop an immunity to it and learn to live with it. For instance, some babies who are born with AIDS have actually developed an immunity to it and no longer have to worry about it. If we do not develop an immunity to a virus, it eventually will kill us...some faster than others. We can't take drugs to help us with this because there aren't any. The only thing we can do is to get vaccinations, which help our body develop an immunity without getting the actual virus, like the small pox vaccination, or Hep B vaccination. Usually kids get MMR and Polio Vaccinations.

Our bodies have all sorts of bacteria, good and bad. The good bacteria generally has nothing to do with keeping the bad bacteria under control. That is why when you have an infection, you have to take an antibiotic to get it under control. Some infections are not that serious and you could actually get by without taking anything...just letting your body figure out how to get stronger than the infection. However some infections can become so serious, you could lose body parts, go into a coma, or die. That's why they give you the antibiotic...to avoid those tragedies.

Answer 2

Our body does not always get rid of Viruses, There are some that will kill you. The reason we cant get rid of viruses on a large scale yet is they haven't come up with a effective antiviral.
Viruses are much more complex then your straight forward Bacteria. One reason is the fact that Viruses are ever mutating.
But we are know getting Bacteria that is resistant to Antibiotics and that may be a big problem in the future.

antibiotics Do kill the Bacteria. A infection is the result of Bacteria. That's why its called a bacterial infection or a viral infection. Because the bacteria or virus have "infected" your body So to Kill the Infection you have to Kill the bacteria. that's why the Anti is in anti biotic or viral, Anti means against.

Answer 3

What The Heck is a Virus?
~~~~~

------------------------------...


Introduction
First, let me tell you what a virus is NOT. A virus is not a bacterium, nor an independently-living organism. A virus cannot survive in the absence of a living cell within which to synthesize copies of itself (replicate). Antibiotics do not harm a virus; it is for this reason that treatment for the "flu" for example, is mainly to help ease the symptoms of the illness rather than to kill the organism which causes the Well then, what IS it?
Now, is there a simple explanation which can define what a virus IS? Hmmmm... that's actually a tough question. A virus is not strictly alive.. nor is it strictly dead... A virus has some fundamental information (genes made of DNA or RNA) which allows it to make copies of itself. However, the virus must be inside a living cell of some kind before the information can be used. In fact, the information won't be made available unless the virus enters a living cell. It is this entrance of a virus into a cell which is called a viral infection. Too, the virus is very, very small relative to the size of a living cell. Therefore, the information the virus can carry is actually not enough to allow it to make copies (replicate). The virus uses the cell's machinery and some of the cell's enzymes to generate virus parts which are later assembled into thousands of new, mature, infectious virus which can leave the cell to infect other cells. Poliomyelitis virus for example, may have over one million copies of its basic genetic information (RNA) inside a single, infected human intestinal mucosal cell.

Answer 4

Bacteria are alive. That means they eat, metabolize and self-reproduce. Virus are not really alive. Viruses don't eat, or metabolize or self-reproduce.
They are packets of RNA in little protein coats. Viruses get inside cells where the RNA is released and tells the DNA in the cell what to do. The instructions are for the cell to make more virus particles.
Antibiotics kill living bacteria, but since viruses are not really alive, antibiotics don't affect them. Our bodies' immune system, however, can detect and seek out foreign particles like viruses, and destroy them before they get into cells. It takes a few days to a week for the immune system to get up to speed, though, and this is when we suffer the worst symptoms from viral diseases.

Hope this helped.

Answer 5

In the old times, our body had to take care of bacterial and viral infection without help of drugs. Bacterial infections were a lot more deadly back then. Many bacterial infections were considered as lethal deseases. Now, with availability of antibiotics, people don't have to suffer those infections so severely.

Now anti-viral drugs are being developed. Some already exist, but they are not as well-developed as antibiotics. Only very few viruses are treated effectively with modern antiviral drugs.

Answer 6

bacteria are killed by antibiotics. Viruses are not killed by antibiotics, they run a course usually and go away, except in the case of herpes or AIDS which are incurable. The common cold is a virus. That's why we don't get an antibiotic for a cold.

Answer 7

Not all viruses are eliminated. Sometimes we do require an antiviral. And not all bacteria need antibiotics. Some infections, both viral and bacterial are self-limiting. That is, they have a finite life-span and then resolve on their own.

Answer 8

You don't usually "need" an antibiotic to get over a bacterial infection- it just helps you get better faster, and people who can go to the doctor generally do because they want to stop feeling lousy as soon as possible. Some very bad bacterial infections we can't get over and might die from if no meds are administered (think E. coli 0157:H7) but there are also some viruses that we can't get rid of either (think HIV or herpes).

Answer 9

We don't need an antibiotic to get rid of bacteria, but we can take it to help alleviate an infection. They have yet to discover an effective anti-viral medication.

Answer 10

ok our body does not get rid of the viruses, they run their course and go away. those that do not leave our bodies include HIV, HBV, HCV, MCV and many more. some of these need treatment some don't. bacterial illnesses can quite often be cured with antibiotics that is why we get these medicines wherever thought effective, good luck
