Viruses have a great tendency to mutate i.e. change their genetic make up.
Therefore medicines cannot attack certain viruses as they do not affect them as many of the medicines are developed to kill viruses with a particular set of genes.The genes of viruses keep changing and therefore medicines are worthless.

∙ 15y agoIn treating a viral infection, all that can be done is to treat the symptoms. Antibiotics are for bacterial infections, they do nothing for a virus. There has been a saying, "You can't kill the virus without killing the host." You just have to treat the symptoms, support the immune system, and let it do what it's designed to do.

∙ 13y agoThere's no such thing as an antibiotic for a virus, only vaccinations. There are some anti-viral agents these days, but none of them are highly effective, so your only real defense against viral diseases is your own immune system, and if the virus attacks that, you're cooked.

∙ 15y agoDifficult to fight, as compared to..... Bacteria?
Bacteria are living organisms, and they are enough different from our own tissues that they can be poisoned by substances that are not especially harmful to us. We call such substances "antibiotic."
Viruses are just tiny fragments of genetic material that get inside our own cells and damage them from the in-side out. They're made of the same stuff that our cells are made of (they have to be, in order to fool our cells into allowing them inside.) They're much simpler than our living cells. To find a substance that can harm a virus that does not do even more harm to the cells that the virus targets is practically impossible, and even if you did find one, it would be so highly specialized that the first tiny mutation in the virus probably would render it immune.

∙ 9y agoThere are two types of infections bacterial and viral. Viral infections are hard to treat, because they are inside the blood cells.

∙ 13y agoBecause most of the time, people can't predict how they will react to something. (they don't have any "pattern's"

∙ 9y agoIt is difficult to control the viruses because they are very good at taking over the cells and reproducing themselves such that they control more cells.

Why viruses are difficult to classify as living organisms?
It is because viruses are not made up of cells
What is the bodys first defense against bacteria and viruses?
Lysozymes
What do Tonsils help defend body against?
they defend against infection and viruses
What do T cells protect the body against?
The T cells help protect the body against viruses.
Interferons are a body cell's defense against?
viruses and tumor cells
Why is it much harder to develop medicines that kill viruses?
because there are may different type of viruses, some of the medicines don't effect it
Why antibiotics are ineffective against viral disease?
Antibiotics are only for bacteria. Viruses need antiviral medicines.
Is it difficult to develop vaccine against viruses because a virus can change its genetic code?
No, its because they are so adapted and any attempt to vaccinate them just sort of "upgrades them" So they become immune to that certain vaccine
Why is microscope an important tool for studying cells and entire organisms?
If we didn't have the microscope, then we would never have known about viruses, we wouldn't have been able to develop medicines for the sicknesses either.
What are antibiotics and what are they used for?
Antibiotics are medicines that cure infections. They have no effect on viruses.
Why it is difficult to isolate drugs effective against eukaryotic microorganisms and viruses?
To find defenses against a eukaryotic microorganism is difficult because we are eukaryotic organisms and any attack on the cell of the microorganism can be an attack against our own cells. This requires a subtle approach. Viruses have no metabolism, are not really living and do not reproduce without a host. So, they leave little open to attack in their simplicity.
Why is the microscope an important tool for studying cells and entire organisms?
If we didn't have the microscope, then we would never have known about viruses, we wouldn't have been able to develop medicines for the sicknesses either.
Can anti sickness medicines kill flu viruses and cold?
Yes. They kill flu viruses, sickness and cold so they can protecting you from getting sick.
What kingdown do most plants and animals belong to when difficult to classify?
lichens, corals, viruses, corals, viruses and carnivourous plants are difficult to classify :)
Why viruses are difficult to classify as living organisms?
It is because viruses are not made up of cells
Why is it difficult to identify computer viruses?
Because you are an idiot
Why do we study viruses?
Viruses have the ability to greatly affect life on earth. Many viruses, such as HIV and influenza have killed millions of people. By studying viruses, scientists are able to develop vaccines that will protect people (and animals) from viruses.
