Out of all medicine y cant we cure???

out of all the medicine we produce and invent why cant we find a cure for aids or even the common cold??

i know what u are all saying but in yrs an yrs to come we should have a cure right??

you need to become a medical researcher so you can find these things.

The HIV virus mutates making it hard for a cure I guess.

The medical industry is making millions off of their products and treatments. I'm sure some of them want a cure for everything, but that would require having them out of business. Think about it....lol..i'm not being completely serious, folks. Yes, I know viruses mutate and are have different strains. I took a Biology course all about it. Lighten up!

The common cold has something like 245 different strains so it'd be virtually impossible to create a vaccine to deal with all of them.

Because these virus' mutate too quickly. By the time we find a cure for one strain, it's already changed and untreatable.

Lets say a virus looks like "X" We create a cure "C" that attacks "X", but it takes 6 months to find and make the cure. During that 6 months, X has changed into "L" and the cure wont work for it.

The HIV virus is like the flu virus...it changes it's shape often and therefor is hard to develop a cure to it. As for the cold I think that our bodies don't need a cure because they already have what it takes to fight it off. It's not as though people are dying form it.

Colds are not caused by viruses but bacterias and that is why our bodies are capable of fighting them.

If a cold were caused by just one virus, we might be able to catch up with it. It's several viruses, though--they mutate quickly.

HIV can lie latent in parts of the body even when it is not detectable. It can hide out where drugs cannot kill/keep every last virus from replicating. Every time it destroys a cell, it's a breeding ground for new viruses. There are multiple drugs for it, but again, the viruses mutate quickly and become drug resistant.

Also, there are some parts of the body (like the brain) where medications cannot easily get due to something called the blood brain barrier. It's like a filter that keeps drugs with certain types of chemical structures out.

The common cold is a clever little blighter of a virus! It is continuously changing ALL the time, so what would cure one cold would not cure the next, as the next one is actually a totally DIFFERENT virus.
