can viruses live outside the body - in cold temperatures (what tempratures and how for long)?
147182
First off, the that's a tricky question because the status of viruses as "living," is debatable.  Many scientists argue that they are not living because they are not capable of independent reproduction, among other things.  However, some viruses can remain virulent in cold temperatures.  Others "die" almost instantly.  Most common viruses that cause disease in humans cannot "live" very long outside the body.

Besides that fact that you can transmit your virus to one of your friends, you really should refrain from exposing yourself to any situation where your immune system would be challenged.  Physical acitivity in water and hot/cold environments is one of those situations.  Give your body the rest it needs until the cold symptoms are no longer present.

no, the disease usually cant live outside the body, it dies immediately from oxygen or the temperature.

Just a quick thought here that may help you.  Under "cold blooded" - or ectothermic - we understand an organism that does not produce a relatively constant body core temperature by means of metabolitic activity etc., but rather regulates its temperature by shutteling between warmer and coller areas.  It takes on the temperature of its environment.  That would be detrimental in case of an animal living in antarctic conditions.  A penguin's blood would freeze, there would be crystalization, and the cells would eventually burst.  In other words, the penguin would be a very cold toast.\n\nNow, there are however ectothermic organisms in arctic and antarctic oceans, which maintain blood flow by using a chemcial anti-freeze.  This has been found, for example in some fishes (the plural is allowed here, since we aretalking about more than one species).  But penguins don't have anything like that and do not need it.  As others have mentioned above, they are very well insulated endotherms (maintain a relatively stable core temperature).\n\nHope this helps in addition to the other answers.

I drink orange juice and water; I still get the cold. Cannot stop viruses, that's my immune system's job.

What is herpes? Simply put, herpes is a virus. And like most other viruses, herpes can be spread between human beings. What makes herpes different from some other viruses is this reality: a herpes infection is forever. With other common viruses, like those that cause a cold or the flu, the virus is eventually destroyed entirely by the body's immune system. Not so with herpes. The herpes virus maintains itself at a place in the body (near the base of the neck or spine) where it is unreachable by the body's defenses. Every so often the herpes virus sends variations of itself along a particular path, to the body's surface (this is known as an outbreak). When the herpes virus shows itself in this way, it can be and usually is killed by the host's immune system. But the clever herpes virus always maintains enough of itself in its bodily hiding place so that it is able to live on -- at least as long as its host does.\n\nSome people become highly distressed by the immortal nature of herpes; others quickly learn to live with it and move on with their lives. Who's got the "right" outlook? Consider that millions of people around the world, if not billions, live with one form or another of a chronic bodily condition: asthma, arthritis, diabetes, high blood pressure, inferior vision, just to name a few. In fact, if a human being lives long enough, he or she will almost certainly develop some form of a chronic condition: it's nearly inevitable. Those people with herpes may have gotten their chronic condition earlier than some, but they also got a mostly benign condition. In whatever form it may take, herpes is very rarely a threat to one's overall health. In short, herpes won't significantly alter your outlook for optimal health and well being (the exception to this can be herpes in an infant or an immune-suppressed person, or ocular herpes: herpes of the eye). This cannot be said for other chronic health conditions: diabetes, for example, or high blood pressure. And herpes outbreaks usually respond very well to treatment. If herpes is the only chronic condition a person should ever acquire, they very well may consider themselves to be lucky.\n\nWhile there are different variations of the herpes virus, the most common are Herpes Simplex Virus 1 (HSV 1) and Herpes Simplex Virus 2 (HSV 2), with HSV 1 being considerably more prevalent than HSV 2. The most common effect of HSV 1 is the cold sore. It's a surprise to some people to discover that a cold sore is in fact a case of herpes. Why the shock? Perhaps because the word "herpes" holds a negative, ugly image in society, while a cold sore is thought to be a benign, temporary condition. In fact, cold sores, like other forms of herpes, are caused by intimate physical contact -- usually kissing. A cold sore is not caused by a cold, and a cold sore doesn't just appear from nowhere. And ocular herpes, which can lead to blindness if left untreated, is almost always caused by HSV 1. It's not an overstatement to say that HSV 1 is a potentially more serious and dangerous form of herpes than HSV 2; and yet very few people think in this way. A cold sore is an acceptable condition; genital herpes, usually caused by HSV 2, is sometimes thought of in shameful, dangerous terms. This kind of thinking is a moral judgment that is not based on fact.\nyes you still have herpes ..There are no universal herpes symptoms; in fact, some people with herpes show no symptoms at all. It's estimated that 80% of persons with genital herpes aren't aware of their status, in part because their symptoms aren't substantial enough to be recognized. There is also a variation among people who do show herpes symptoms: some people display certain symptoms, other people display different symptoms.\nThere is no absolute time frame from a herpes infection to the appearance of herpes symptoms. Some people show symptoms days after becoming infected with herpes, s

Usually after you catch one virus, your body has an immunity to that virus, so you won't get it again.  However, cold viruses mutate rapidly, so there are new ones around all the time.

For: They can be classified as living beings because they contain either DNA or RNA and/or a protein coat. The DNA/RNA are components of all living organisms and hence virus having a component present in the living organisms can be called as a living thing.\n\nAgainst: On the other hand, virus are "living" only when present in another living organisms or the hosts. When they are present free in the environment they can only be considered as PARTICULATE MATTER which can be "crystallised and preserved". There are some virus only with protein coat and no DNA&#92;RNA.\n\nThus the classification of viruses is very difficult. Hence they have been placed under a different heading as viruses.

Viruses enter your body from other bodily fluids, whether it be blood or saliva, excrement or vomit.  Viruses generally travel easier in the medium they affect, AIDS is blood-borne, and while it's possible a blood to blood transfer would infect you with a common cold or flu, it's generally spread by saliva. Generally viruses cannot survive for long outside of a host organism.\n\nYour body is under attack by viruses constantly, many times you will receive a virus and not even know because your body is able to fight it off before it can affect you. Besides the obvious, visible or physical symptoms of an infection, a doctor can test for anti-bodies to see if you've been infected. The main reason we give vaccinations is so your body can fight off a weakened or dead virus and learn to make the anti-bodies to defeat it for the next time you are infected by it. However some viruses can remain dormant for long periods of time and even tests cannot show their presence, since the viral load (amount of virus particles) is so low.  \n\nOn a side note, contrary to what was said above virus are NOT organisms. By the definitions of life it is not alive, technically it is an obligate intracellular parasite. This is for a few reasons, but the big ones are that they are not cellular based and they cannot reproduce (by themselves). They do share characteristics with living things, such as the use of DNA/RNA and the ability to evolve.

Here's some more info about how colds are caught:\n\nThe viruses are transmitted from person to person by droplets from coughs or sneezes. The droplets or droplet nuclei are either inhaled directly, or transmitted from hand to hand via handshakes or objects such as door knobs, and then introduced to the nasal passages when the hand touches the nose or eyes.\n\nThe virus takes advantage of sneezes and coughs to infect the next person before it is defeated by the body's immune system. Sneezes expel a significantly larger concentration of virus "cloud" than coughing. The "cloud" is partly invisible and falls at a rate slow enough to last for hours—with part of the droplet nuclei evaporating and leaving much smaller and invisible "droplet nuclei" in the air. Droplets from turbulent sneezing or coughing or hand contact also can last for hours on surfaces, although less virus can be recovered from porous surfaces such as wood or paper towel than non-porous surfaces such as a metal bar. A sufferer is most infectious within the first three days of the illness. Symptoms, however, are not necessary for viral shedding or transmission, as a percentage of asymptomatic subjects exhibit viruses in nasal swabs, likely controlling the virus at concentrations too low for them to have symptoms.

Colds are caused by viruses, not 68 degree weather.  I always sleep with the temp around there and I have never had any problems. So long as the children have adequate blankets and warmth at night they should be fine.  A lot of people prefer a colder temp setting at night.   I've always been weary of humidifiers because I am very sensitive to mold, but if they have never had any problems with it I wouldn't worry.  Kids get sick all the time, that's just a part of life, it's not from the temp setting.

Usually if you have 82 degrees in November, you usually have a big cold outbreak in december.  I think you mean can anybody change the weather for you?  I think 82 degrees is a little on the warm side so i am with you.  Just  hang in there.  Cooler weather should be on it's way.

body temperature is 98.6 F when you enter a cold environment your body has to work harder to keep it at that temperature otherwise it would drop to the temperature of the room.if the environment is sufficiently cold you body has to work so hard to keep it at 98F that it cannot keep you awake and warm at the same time.the effect is similar to feeling tired after eating a heavy meal

I believe that it is becuase since it is cold outside, people tend to stay in more, allowing for easy spreading of viruses.\n\nDon't quote me on it\n\n\nR

As a rule, no.\nIt could arise \n1. as answered already, if the surrounds are above normal body temp (the body while alive being cooled by sweat evaporation),\n2 If the body cooled towards equilibration with the surrounds, then the surrounds warmed up above the lowered temperature which the body had reached,\n3 If the evaporation of moisture cooled the body, it could certainly cool the skin significantly, but I suspect the skin would dry long before this cooled the average body temperature below that of the surrounds. (perhaps more significant if wearing a lot of wet clothes if a dry wind)\nAny other circumstances anyone? - even more bizarre ideas such as death from hypothermia following massive ingestion of ice??

You should be fine.  Frostbite from that probably takes extended exposure to the cold instead of just the little bit of time that you had.

Technically, a virus is just a single strand of RNA in a protein shell. If you can get it hot enough to denature the protein, it should "die," though I don't believe it is technically "alive." Viruses work by using your living cells to replicate themselves. They can't do it on their own. When you catch a cold, your cells become little virus factories, churning out millions of replicas of the virus that can then get into other living cells and infect them. That's how viruses spread, multiply, and mutate within living organisms. Fire probably destroys just about any virus, but I'm not going to say that with 100% certainty. Hope that helps a little.
