Viruses like norovirus & enterovirus can live for weeks on hard surfaces, but what about fabric - how long do viruses survive on a sofa or pillow?
Good question: Almost same life span. Can be little less if it is washed in hot water. ...Read more

Hi, I was diagnosed with HPV/ Genital Warts in March this year. How long does virus take to leave the body? And it is useful now to still vaccinated?
Years/yes: The primary infection usually clears within 2 years spontaneously in people with a normal immune system. Many have visible warts removed (laser, frozen, chemical agents) but the germ itself will often hibernate in your system forever and may recur. The most recent vaccine helps protect against 2 wart strains and 7 cancer associated strains if you have never had them. You would get some benefit. ...Read more
How long can viruses or bacteria from eye infection live on surfaces - porous (stuffed animals)& nonporous (door knobs)?
Complicated viruses: It depends on which virus you're considering - the problem is there are so many viruses, it's really like a whole universe. Some viruses write themselves into our DNA - like HIV-1, hepatitis B virus - so they last as long as we live... Others are cleared out by the immune system, if recognized. So if you have a more specific Q about a certain virus, we can try to answer it. ...Read more
How long does a virus last? Can it last months? I have been very ill and the doctors just say virus.
Not long: Viruses are critters which live inside cells and must have nutrients of a cell to remain alive. Most will die rapidly after leaving the body unless retained in body fluids within cells in those fluids. This takes varying times to resolve. As a general rule HIV is not transmittable casually. It needs direct tissue contact. Blood, shared needles, sex, organ transplant. ...Read more
Toilet seat: There has never been documentation of any infection passing to an individual from a toilet seat. ...Read more
Depends on person: Hiv can be clinically "latent" (present but causing no symptoms) for periods of months to years with some people being infected for up to 8 to 10 years without serious symptoms. This period of time is unique to every person and depends upon other factors such as other illnesses, nutrition, baseline health, age, etc... People with "dormant" disease are still potentially infectious to others. ...Read more
How long does noro virus last in a luggage? My dad got sick on vacation, and I'm wondering if I can still catch it. (We were on vacation in December)
Probably no risk: I'm not aware of any research on whether luggage can carry norovirus for such a long time. However, there are also no scientific reports that anyone ever caught the virus from using contaminated luggage. If the luggage was directly contaminated, such as someone vomiting on it, clean it with a disinfectant soap. Otherwise don't worry about it. ...Read more
Transmissability: The maximum risk of contagion lasts one week after the beginning of symptoms. The recovered person may remain mildly contagious for a couple of weeks after recovery. Pregnant women should be especially careful as they can pass down the infection to the fetus and coxsackie infection has been known to cause birth defects. ...Read more
Depends: It depends on what you mean by dormant. Blood tests are generally positive within a few weeks of infection, and many people develop temporary symptoms during acute infection. However, after recovery from acute infection, you may have no symptoms for many years. On average, it takes 10 years to progress to aids without treatment. ...Read more
How long can HIV virus survive on lipsticks? I used a HIV friend's lipstick that she used a month before.
Even if your friend has HIV, there is minimal risk. If you wish to be tested get a HIV nucleic acid test in 6 months, if that is negative it would rule out HIV.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex.
Get HPV vaccine. ...Read more
How long does the virus live on chapstick, can I re infect myself by using my own chapstick later after I have had an earlier outbreak?
Oral herpes?: You don't say what virus is on your mind, but I'm guessing you have recurrent oral herpes (cold sores). If so, you needn't worry at all. You are resistant to new infections with the same type of herpes (probably HSV1) and certainly cannot reinfect yourself with your own virus. Feel free to re-use the same chapstick. (It has a preservative that would kill HSV, but it woudn't matter if it didnt.) ...Read more
See below: The virus in nonifectious when it dries out & exposed to sunlight. Many types of rabies virus exist (raccoons, skunks, foxes, coyotes, bats) and are associated with a particular animal. Typically, the time from exposure to the virus until clinical sxs appear (aka incubation period) ranges from 1-3 months (sometimes days-years). Once clinical signs of rabies appear, the disease is usually fatal. ...Read more
How long can herpes virus last outside the body in a freezer? Like if an infected person touches icecube and put it in freezer. How long will it last
HIV: life outside: Hiv needs a host or culture in a range of the average body temperature. Outside a body, the virus is fragile and dies within minutes if it is allowed to dry up. Hiv can sometimes stay alive for days inside needles of used syringes because there is enough blood to keep it from drying out. ...Read more
HIV is hard to get: Probably seconds... If that. This persistent question is getting tiresome. Please state your real purpose for repeatedly asking this type of question. Why, at 70, are you persistently and rudely ignoring the repeated answer? ...Read more
If I took a sip from a friends straw but she didn't have a cold sore or anything and I don't know if she gets them how long can the virus live on astraw?
Herpes: 75% of americans have herpes. It is more likely that you are already have herpes than not. If you have not had the blood test for herpes then that has to happen before you worry about other infections. But, in this scenario it is possible if there is immediate exposure to your friend's straw to getting virus if they have herpes. There is no standard time to consider. Please get tested. ...Read more
