Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

How much time HIV virus can survive outside body?

How much time HIV virus can survive outside body?

It doesn't: HIV does not survive outside of the body. It is not ever caught by touching it or any other thing it is in or on. Millions of humans have now survived HIV free after taking care of infected humans. They have been bled upon, shat upon, vomited on, spit upon, peed upon. HIV is not caught by touching it or anything it has been in contact with. ...Read more

How is the HIV virus passed into the body tissues?

How is the HIV virus passed into the body tissues?

Various ways: The virus has reservoir cells where it remains inactive in tissues. These are macrophages and in the nervous system some neurons. It lives within lymphocytes (cd4 cells), and other cells which possess a receptor site to which it can attach and enter the cells. These cells then carry it into tissues. When the virus first enters the body it does so onto receptive surfaces. ...Read more

How long could HIV virus remain active in a person's body without manifesting itself?

How long could HIV virus remain active in a person's body without manifesting itself?

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

When (i mean how many years/months after) HIV viruses will show symptoms in human body?

HIV infection: The acute infection stage of HIV usually begins to be widespread at about fourteen days after exposure. Most people do not experience any symptoms during this phase. But, those that do report a severe flu-like illness. Untreated, in a man, the average length of infection to death is eleven years.But, we do not need to worry about that. With treatment today, the length of life is 53 plus years. ...Read more

How long HIV does live outside the body? If it is a tiny or little more amount of fluid? How long it takes the virus to die in a fluid wet or dry?

Why: It doesn't survive. But that doesn't matter. Hiv is not caught by touching it or the fluid it may be living in. That is very well understood. What is your specific concern? ...Read more

Can HIV establish itself in the body if there was only 1 virus particle? I am just curious if there needs to be a decent amount of the virus or not.

Can HIV establish itself in the body if there was only 1 virus particle? I am just curious if there needs to be a decent amount of the virus or not.

HIV: Most pathogens have a minimal infective dose necessary to initiate infection. Some only need a single organism to do this. Hiv is probably in this category but only in the laboratory. It would be exceptionally rare for you to be exposed only to a single virus in real life. Be very careful out there. ...Read more

How does an HIV virus interact with cells in the body?

How does an HIV virus interact with cells in the body?

Too complicated: It is a complex subject. In short, HIV virus kills T-lymphocytes and degrades immune system. That results in other infections and tumors. There are effective treatments. See this site for more information.

How long does HIV virus remain dormant in a person's body?

How long does HIV virus remain dormant in a person's body?

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 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

How much is the lifespan of the HIV virus outside the human body?

Very brief: This virus is very susceptible to physical elements, particularly drying, heat, cold, etc. It may survive slightly longer when present in warm wet material like semen or vaginal secretions, and particularly in blood. As soon as these dry the organism will die quickly. ...Read more

Normally, how long would the hiv/ aids virus live in the body once a person passes away?

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

Hi, how long can an HIV virus last outside human body (like on needle or something) that it can be considered a risk?

HIV virus: Hiv is extremely sensitive to fluctuations in temperature.Outside of the human body, the virus dies within minutes. The one place that HIV has been shown to survive for extended periods of time (several days) is in needles used with syringes; the needles frequently contain enough blood to prevent the HIV from drying out. ...Read more

Can i get HIV by a puncture with discarded needles o syringes? How many time does the virus survive outside the body?

HIV: Hiv can be transmitted through needles and syringes contaminated with infected blood. Hiv may survive for up to four weeks in syringes after hiv-infected blood has been drawn up into the syringe and then flushed out. ...Read more

Have a blood test: It is true that it can take 10 years or even more for HIV to cause serious health problems. However, the blood tests for HIV are accurate much sooner. Depending on the particular test or combination of tests, HIV can be accurately diagnosed as soon as 10-12 days after infection and always within 3 months. If you think you may have been exposed, get tested. ...Read more

If becoming in contact with HIV and the virus is in their body a short period of time, can they still spread the virus to others by sexual contact?

If becoming in contact with HIV and the virus is in their body a short period of time, can they still spread the virus to others by sexual contact?

Yes: Once someone is newly infected with hiv, the virus replicates very quickly at first, making the amount if the virus higher. When this happens it is easier to pass the virus to someone else. Most new HIV infections are spead from someone who does not know his/her HIV status. So, always use condoms. Get HIV tested! if you have HIV see a HIV specialist. ...Read more

Can HIV be transmitted through underwear, if the other partner while he was wearing underwear touched the naked penis of me, assuming she was HIV+, and I climaxed after such touch, can the virus go inside my body? do I need to test?

Can HIV be transmitted through underwear, if the other partner while he was wearing underwear touched the naked penis of me, assuming she was HIV+, and I climaxed after such touch, can the virus go inside my body? do I need to test?

No: Get tested anyway. Either something else happened, or probably will soon. If you are having fun with people you don't know well, it's good to get checked yearly. I hope you'll treasure your adventure, imperfect as human love always is, and that perhaps someday you will find true love. ...Read more
