How Long Does The Hepatitis A Virus Survive Outside The Body
How long can the HIV virus live outside a human body? If the body fluid it is in is dry, would the virus die?
Within few hours: Cdc has conducted many studies on HIV concentrations outside the body, when these are dried, the virus is reduced by 90to99% over several hours, these concentrations were much higher than they will be outside lab, making theoretical envorenmental transmission outside the body to zero. ...Read more
Few hours when dry: Cdc has conducted many studies on HIV concentrations outside the body, when these are dried, the virus is reduced by 90to99% over several hours, these concentrations were much higher than they will be outside lab, making theoretical envorenmental transmission outside the body to zero. ...Read more
HPV: Not long. If you are concerned about transmission of this virus by other than direct person to person contact this is very very unlikely. If you are using a dildo, however, and it is in direct contact with an hpv infected individual and then immediately used by another, this has the potential to transmit the virus. ...Read more
Less than a day?: I don't know of a study on this but in general most viruses don't survive long in dead tissue. Attempts to culture virus post-mortem are usually done as quicly as possible for that reason. I would suspect the success of such a culture more than 24 hours after death would be low. ...Read more
Depends on details: Realize that "outside the body" can mean: on the surface of my arm, on my steering wheel, in a freezer at the lab, on a bagel, etc... So, there is no answer unless the question defines Where, What acidity (pH), What temperature, What humidity, What lighting (sunlight, amount of UV), etc.. From a daily life standpoint, there is no worry about catching HIV on any surfaces that we routinely touch. ...Read more
Not long: The virus requires temperature very close to 98.6 and proper moisture. Exposed to an open environment without these conditions, it begins to die immediately, especially in small volumes. It might still be advised to use protection in direct contact with contaminated body fluid spills, but the risk is very low outside the body. Take care ; be well. ...Read moreSee 1 more doctor answer
How long does the herpes zoster virus survive outside the body?ie . after the fluid breaks out from the blister?
Virus dies quickly: If things are 'dry', then the virus will die off. However if the blister pops & wet material comes out -then potentially a new person could become infected with the chickenpox virus. Chickenpox has to occur first, before zoster can occur. If that person who was exposed had the chickenpox vaccine, then u can breathe a sigh of relief because they should be protected. No transmission if DRY scabs. ...Read more
How long does hpv survive outside the body. What disinfectants will kill the virus on a surface. Does washing and drying your clothes kill the virus?
Doesn't matter: You're asking the wrong question. It doesn't matter whether HPV survives away from the body, on clothing, on a surface, etc. Contact with these things never transmits the virus. Without sex or other direct skin-skin contact with an infected person, nobody ever gets HPV. So no need to worry about it. ...Read moreSee 1 more doctor answer
Not long: Viruses require living cells in which to propagate in order to remain viable. As soon as they are expelled as free virus they will not last long against environmental conditions. If living cells containing virus are excreted, they too will not survive very long. This is one of the reasons that there is seldom if ever transmission of these agents by inanimate objects. ...Read more
It depends: Hsv virus is easily inactivated by exposure to ph <4, temperatures >56°c for 30 min, pasteurization (60°c for 10 h), and microwave heating for 4 minutes. Survival outside host: hsv virus survives for short periods of time outside the host. It can survive on dry inanimate surfaces (survival ranges from few hours to 8 weeks). They survive longer at lower humidity. ...Read more
How long does human herpes 8 virus , the one that causes kaposi sarcoma, live outside the body on a door handle?
Not very long: People often ask this question because of concerns if they pick up or prick themselves on a dirty needle. HIV does not survive well outside the body. Once the liquid (blood, semen, vaginal fluid, etc.) it is in has dried, the virus is dead and not transmissible. So an old dirty needle, if dry, cannot transmit HIV. Other viruses such as hep b and hep c are much hardier and can survive longer. ...Read moreSee 1 more doctor answer
