What Happens When Viruses Infect Your Body?

AI Thread Summary
When a person contracts a common cold or virus, the virus infiltrates cells, hijacking their machinery to reproduce itself. This triggers the immune system, leading to symptoms like fever and a runny nose as the body attempts to eliminate the virus. Antibiotics target bacteria by disrupting their cellular functions, such as cell wall construction, but are ineffective against viruses, which lack independent machinery. There are numerous types of both viruses and bacteria, with viruses often considered non-living as they cannot replicate without a host cell. Bacteria, on the other hand, are living organisms that can evolve rapidly, making them challenging to eradicate completely. The presence of colored mucus typically indicates a bacterial infection rather than a viral one, as it results from the byproducts of dead bacteria. Despite their simplicity, bacteria have thrived for billions of years, complicating efforts to develop permanent solutions against them.

I am new at this but i want to make sure i know what i am talking about
I have researched this but i haven't gotten a straight answer

1. When you get sick(common cold/virus) what happens?
Does virus go into each cell and take its nutrients.
Then after that does it keep on spreading and then your body tries to kill it and then you get fever and runny stuffy nose.
2. When you take antibiotics how does it kill bacteria?

and are there different types of bacteria so wouldn't they be the same as viruses

Also i remember long ago i heard one of them was living is that true or not.

1] Virii, because they are bits of DNA, are able to sneak past cells defenses and enter the cell. There, they hijack the cell's machinery and force the cell to start reproducing the virus' DNA. When your body begins sensing these foreign bodies, the defense system is activated - the one we notice most is a big increase in histamines, which pump fluids into your tissues and mucous membranes. This is designed to (belatedly) trap more irritants entering the body.

2] Antibiotics are carefully chosen poisons that target bacteria. They interfere with the bacterium's ability to work, such as constructing its cell wall. This is also why antibiotics don't work on virii - virii are not working machinery.


There are as many kinds of virus as there are bacteria.

Virii are on the verge of life. Many consider them non-life. They are simply bits of DNA. They cannot work without hijacking a living cell.

so if well where do these virii attack
because if they attack in the lower part of your body then when you sneeze would you still get colored mucus

ok and if i get this straight bacteria is a very simple machine
if they are so simple can't humans create something to stop them for good

I may be mistaken but catching a virus does not produce coloured mucous at all. The byproduct of bactgerial infection is the carcasses of bacteria, whose byprodiucts are poisons and have (colour and taste). The offal of a virus is your own cells.

Do not confuse simple with easy. Humans may be the most complex critters on the planet, but bacteria are by far the most successful - they've done quite nicely for 2 billion years.
 
(1) The virus infects a cell, tricks the cell into making more copies of that virus until the cell ruptures and sends those new virii out to infect other cells. Fevers, runny noses, etc. are some of our bodies attempts to get rid of the virus. Of course, some types of virus use runny noses as a way to spread themselves to new hosts.

(2) There are countless types of virii and bacteria. A virus is a bit of DNA or RNA with a protein coating. So they are often thought of as non-living. A bacterium is an independent living cell (single celled organism). A cell is not exactly a simple machine. That aside, bacteria are hard to get rid of because they reproduce extremely quickly and they also evolve quickly. New strains appear and existing ones evolve defenses to attacks on them (which is why antibiotics can become less effective over time).

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
