How long is a cold infectious?

I don't know Johnny, but if he's still sneezing and wheezing, I would bet he is still contagious.  They are spread by respiratory droplets, which are produced by sneezing or coughing, also by getting these on inanimate objects, and then you touching them, and then touching your nose or mouth or food.  There are many strains of colds, which is why we keep getting them, but I think the older you get, the less you get them, because you may have had them before, or they get less severe, because you have had one quite similar and have some immunity.  Of course every one who sneezes or wheezes doesn't have a cold.  They could have an allergy or asthma or they could have rhinitis from being a coc addict or a meth addict or some people have rhinitis medicamentosa, which is rhinitis from using too much nasal decongestant spray like Afrin.  It's normal to sneeze in response to cold air or dust or allergens.  It's normal to do a little coughing and smokers do this much more.

Usually about 6 months from the time of diagnosis, but it can vary anywhere from a few days to 12 months.  It depends on the person, how long they have had it, where it has spread from, where it might have originated, etc.

No. It takes about two weeks (10-14 days) for the virus to infect the initial cells. Testing for antibodies is not that acurate. It could be possible to test negative for antibodies after twenty years.

Common cold is a viral infection of the nose and \nthroat. There are hundreds of different types of \nviruses which can cause common cold.These \nviruses are transmitted from an affected person \nto another directly or indirectly.

Flu, if that's what it is, can last several days to a week. On top of that, if you are running a fever, you are contagious...it's neither polite nor ethical to go out with your friends while you can spread the flu. Stay home, watch TV or read a book, go to bed early and take good care of yourself. You'll get better and you won't give your friends the flu.

Sorry to say but you cannot cure a cold.  It is a virus and there are almost no viruses that can be killed by medication.  Bacteria can be killed, but not a virus.  So, just make the symptoms as bearable as possible and wait.  It will be over in a few days.

Colds are actually contageous for at least a day or two before you show any symptoms.  Then once it hits, you remain contageous for another three to four days.

Absolutely - a cold sore is a herpes outbreak. So it is absolutely contagious and incurable.\n\nPeople are saying it's "a version" of Herpes, and "herpes' little sister," No.  It's Herpes, period.  Simplex 1, 2, 76 - who cares.  It's HERPES.  Not herpes' little sister, or a variation on herpes, or sorta kinda like herpes in a way, or herpes the remix.  It is pure and simple herpes.  Cold sores and fever blisters are attributed to colds and fevers because the symptoms that accompany the outbreak are cold/flu-like symptoms, ie, cold/fever.  Please do not let anyone LESSEN the idea that this sore is evidence that someone is infected with the herpes virus... no matter their age.  And please understand that you can STILL contract and/or transmit the herpes virus even when there is no outward evidence of an outbreak.

The common cold is a viral infection. It can be manifested in different ways by different people. The manifestations during a common cold as well as the flu depend on your body's immune system response. The common cold is usually less severe than a strain of the flu virus. The common cold usually starts as some type of respiratory viral infection and can commonly cause host susceptibility to bacterial organisms. The flu virus acts more aggressively and has some effects on the nervous system. These effects cause the severe headaches, body aches, lack of body temperature control, and muscle aches that accompany this disease. At this time, there are no direct treatments for either of these viral diseases. The goal of treatment for both is to manage the symptomatology of the disease. For example, Tylenol/Ibuprofen for fever, etc.

See my blog, 4 October.  Most colds last from 36 hours to 3 days max.  Shame if its on a weekend.  Love your 360 theme!

A "cold" is usually a viral infection.  These take about 3-5 days to be recovered from.  The best way to help your immune system get the job done is to have lots of rest, drink lots of fluids, especially water and just take care of yourself by not exposing yourself to other sick people so you don't get a second infection at the same time... which can and does happen often.

Incubation periods\nThe new report says the virus may incubate longer than other human flu viruses before causing symptoms. Incubation periods in ordinary flu range from 1 to 4 days, with an average of 2 days. \n\nIn bird flu cases, the incubation time has mostly been from 2 to 4 days but has stretched to 8 days, the report says. In household clusters of cases, the time between cases has generally ranged from 2 to 5 days but sometimes has been as long as 17 days.\n\nyou might wanna get some more info about the bird flu through these sites: http://bird-flu-symptom.info/category/symptoms/\nwww.agnr.umd.edu/avianflu/

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.

A cold is a viral infection and is caught from contact with other people and things that others have been in contact with.  \n\nWashing his hands more often would help and not touching his eyes and nose.  Also he should limit contact with people who have colds, especially during the first three days of their illness.\n\nIf he still finds he is repeatedly getting colds I would recommend seeing a holistic practitioner, who can look at all affecting factors.\n\nP.S. It has been scientifically proven that going out in the cold does not give you a cold.

a cold is a virus that goes to your throat. there, it injects it's DNA into your cells, which start producing more viruses. when they are complete, the cell explodes, letting the new virus multiply as well. thier goal is overrun your entire body for survival. the coughing is caused by the fragments of the exploded cells which collect in your throat. your body coughs to expel these particles.

Zinc tablets or pills and some good sleep :)\n\nCuts the common cold down by over 3 days :)
