Why dont we become resistant to all diseases?

Question

Once mumps or measles occur then it doesnt occur again because antibodies are produced.Why this formula not applied on other diseases like cold, influenza, fever?because these diseases affect again and again the same person.
why antibodies against these diseases not produced in the body and if produced then why we suffer again and again?

Answer 1

the thing is, measles, mumps, varicella (chicken pox) have only one strain of the virus... however, bacterial infections for colds have different strains. the principle is that our immune system recognizes and "records" or puts into memory all the infective strains like bacterial or viral strains that infect us thus when the same bacteria or virus infects us, our body/ immune system recognizes this infection and fights it off - or what you meant of being "resistant" to it. However, the problem is when there are so many strains of these infections such as colds, flu, etc. thus, even when we think that we already had a cold a few months back and we again acquire a cold, it is not the same strain of infection... thus our immune system does not recognize the infective strain, therefore the signs and symptoms of infection.

Fever on the other hand, is a very general symptom of an infection. It is not a specific symptom of a sickness thus when you are infected with a bacteria, a virus, a fungus or a parasite, you will have the symptom of fever. =)

i hope i was able to help...

Answer 2

You're thinking of diseases as if they are individuals that are easily identifiable. A disease is a state of being unhealthy. A particular disease may have many different causes. Once you catch a cold, you will likely develop an immunity the the virus which gave you that cold, but there are hundreds of other viruses which will give you a cold.
Similarly with Influenza, you may develop immunity once you have caught and survived the flu, but only to the particular strain to which you were exposed. Its same reason why we need to be immunised each year against influenza.
Measles and mumps are each caused by single viruses, so exposure will give you immunity.

I believe I can give you some important information about how the human body functions around all the diseases it's subjected to.

Most diseases are parasites or bacteria looking for a place to live and grow.

The human body is a good host to many of these.

By building the body up through wholesome nourishment and sound planning, you eliminate the possibility of many of these diseases taking refuge in your body.

So, do an experiment. Try growing a garden without the use of a pesticide.

Soon, all of what you grow will be affected by many organisms, and you will have virtually nothing left worthy of human consumption.

Try it again, only this time get yourself garlic and surround all your plants with pieces of garlic.

There will be a big difference.

Do the same to your body, and you will be fighting off all those bad diseases the same way.

Answer 4

It is because cold and flu virus's are constantly mutating. When your body recognizes a virus it sends white cells to fight it and produces antibodies specifically for that intruder. Thus it will recognize that exact virus again. Unfortunately even a small change in the virus's protein layer render it unrecognizable. Think of it this way when you type in a web address it has to be exact, if one letter is wrong the computer can not direct you.

Answer 5

So far no one has come up with a cure for the common cold or the flu or some fevers. The answer of why is unknown to medical science. But these common illnesses and other diseases must be in existence for our bodies are only temporary for us to use. Our bodies are meant to get sick and eventually die. If they wouldn't, this planet would be over run by tens of thousands of people and sooner or later our food and water supply would run out and many other disasters would take place. This world would not be very nice for too long. Every time a person dies, a baby is born. The cycle of life is always in motion and it can be rather complex.

Good luck to you with your answers. I hope I was some what helpful.

Answer 6

The man or woman is correct in that there are lots of avenues that manage infectious sicknesses. He is speaking approximately an epidemiologist, who tracks and follows infectious sicknesses. Otherwise, you could get an undergraduate measure in biochemistry, microbiology or different similar fields after which follow to graduate tuition. During your residency you could by and large begin in inner remedy after which upload different locations later. A PhD could result in study in a few detail of infectious sicknesses. So--a heavy lifestyles sciences UG at a well tuition with most sensible grades and a well MCAT, plus a few enjoy in wellbeing sciences, could aid you be aggressive at JH Medical. Don't omit there are different very well clinical faculties, and also you must maintain your choices open.

Answer 7

EVOLUTION-the bacteria, viruses, fungi, etc. adapt to their environment by mutating at a MUCH faster rate than we do. Bacteria can share plasmids, and therefore adaptations such as antibiotic resistance, across different species E.coli and Shigella for instance ( deadly form of E.coli emits a Shiga toxin-a trait it picked up when it absorbed a plasmid from Shigella. E.coli normally doesn't emit toxins. ). Viruses can grab a piece of the cell wall and wrap themselves to hide from the macrophages in our bodies.

Answer 8

You wouldn't want to become immune to all diseases, and I pray this never happens. There is a need for population control, and although everyone has a "not in my backyard" mentality about it, we all need to die. In case you missed it, they just announced the other day there are 300 million idiots living in this country. Did you here me?!?!? I said 300 million!!! Could you imagine if they found a cure for everything that ails us how freakin' miserable we would be with 300 BILLION morons living on top of us?!?!? Perish the thought!!! 300 million is enough, and in my humble opinion, that is way, way too many!!! In case you missed it, I ain't much of a people person!!!

Answer 9

Because as we grow immunities, so do the diseases. They're living things and if you've ever noticed when they make vaccinations, they don't stick with the original. It's constantly updated to protect from the virus and it's new forms or abilities. That's how people still get the diseases.

Answer 10

you do become resistant to germs you have had,but there's like a billion different germs and they all mutate like when people don't finish antibiotics and I wonder if all these germ killing sprays and soaps might cause some mutating if not used properly
