How Quickly Can You Contract Hiv

How Is Hiv Transmitted

How soon after unprotected sex you will be 100 % sure of HIV status? – Dr. Sapna Lulla

HIV is transmitted between humans through the exchange of certain types of bodily fluids. Bodily fluids that can transmit HIV include blood, semen, breast milk, and vaginal fluids .

Not all body fluids can transmit HIV. The following cannot transmit HIV:

  • Exchanging saliva, like through closed-mouth kissing or sharing drinks/utensils
  • Coming in contact with an HIV positive personâs tears, sneezes, or sweat
  • Ordinary physical contact, such as hugging, hand shaking, or touching shared objects like cutlery, cups, or toilet seats .
  • Air or water
  • Pets and insects cannot carry the virus and infect you, because transmission of HIV is only between humans .

While care needs to be taken in some situationsâlike when having sex or when open injuries are presentâthis certainly does not mean that it is unsafe to be around people with HIV. Think of how you interact with the vast majority of peopleâbodily fluids are not exchanged. Harboring discriminatory thoughts only perpetuates a fearful stigma against someone with HIV, which only hurts the person who has it.

HIV is often transmitted through sexual activity and drug use in adults in the United States . Maternal transmissionâfrom mother to childâis how the infection is spread to infants .

Latency Causes A Break In Symptoms

After initial exposure and possible primary infection, HIV may transition into a stage called clinically latent infection. Its also referred to as asymptomatic HIV infection due to a noticeable lack of symptoms. This lack of symptoms includes possible chronic symptoms.

According to HIV.gov, latency in HIV infection can last for 10 or 15 years. This doesnt mean that HIV is gone, nor does it mean that the virus cant be transmitted to others. Clinically latent infection may progress to the third and final stage of HIV, also referred to as AIDS.

The risk for progression is higher if a person with HIV isnt receiving treatment, such as antiretroviral therapy. Its important to take prescribed medications during all stages of HIV even if there arent any noticeable symptoms. There are several medications used for HIV treatment.

Do I Still Need To Worry About Other Sexually Transmitted Infections

Neither HIV treatment nor PrEP prevents other sexually transmitted infections, or STIs.

Ways to reduce the risk of STIs include having both partners tested, limiting the number of sexual partners and using condoms. Vaccines are available to prevent some STIs, including hepatitis B and human papillomavirus .

Are Hiv Medicines Used At Other Times To Prevent Hiv Transmission

Yes, HIV medicines are also used for post-exposure prophylaxis and to prevent mother-to-child transmission of HIV.

  • Post-exposure prophylaxis PEP means taking HIV medicines within 72 hours after a possible exposure to HIV to prevent HIV infection. PEP should be used only in emergency situations. It is not meant for regular use by people who may be exposed to HIV frequently. For more information, read the ClinicalInfo fact sheet on Post-Exposure Prophylaxis .
  • Prevention of mother-to-child transmission of HIV Pregnant women with HIV take HIV medicines for their own health and to prevent mother-to-child transmission of HIV. After birth, babies born to women with HIV receive HIV medicine to protect them from infection with any HIV that may have passed from mother to child during childbirth. For more information, read the ClinicalInfo fact sheet on Preventing Mother-to-Child Transmission of HIV.

Stage : Acute Primary Infection

HIV Test

The early symptoms of HIV can feel like having the flu. Around one to four weeks after getting HIV, you may start to experience these flu-like symptoms. These normally dont last long . You may only get some of the symptoms and some people dont have any symptoms at all.

Symptoms can include:

  • joint aches and pains
  • muscle pain.

These symptoms happen because your body is reacting to the HIV virus. Cells that are infected with HIV are circulating throughout your blood system. In response, your immune system tries to attack the virus by producing HIV antibodies this process is called seroconversion. Timing varies but once you have HIV it can take your body up to a few months to go through the seroconversion process.

Having these symptoms alone does not mean you definitely have HIV. The only way to know if you have HIV is by taking a test. You should always visit your healthcare professional if youre worried about or think youve been at risk of getting HIV, even if you feel well and dont have any symptoms. They can then arrange for you to get tested.

HIV will not always show up in a test at this early stage, and you may need to test again later to confirm your result . Your healthcare professional will talk to you about the timing of your test and answer any concerns. Its important not delay speaking to a healthcare worker if you are worried about HIV.

Viral Load At Different Stages

During the first few weeks after someone gets HIV, viral load is usually very high typically several million viral copies per millilitre of blood . There is a considerable risk of passing on HIV at this point. In fact, many people acquire HIV from someone who has only recently acquired it themselves .

After this period of early infection, viral load usually drops. A typical viral load in someone not taking treatment may be 50,000 copies/ml. There is still a considerable risk of passing HIV on.

After starting HIV treatment, viral load usually falls rapidly. Within three to six months, most peoples viral load has become undetectable.

Most clinics in the UK report a viral load as undetectable if it is below 20-50 copies/ml. However, if your viral load remains below 200 copies/ml , there is no risk of passing HIV to your sexual partners. There is no need to worry if your viral load goes slightly above the detection limit of 20-50 copies/ml.

detectable viral load

When viral load is detectable, this indicates that HIV is replicating in the body. If the person is taking HIV treatment but their viral load is detectable, the treatment is not working properly. There may still be a risk of HIV transmission to sexual partners.

Does Hiv Treatment Always Work

About one in six people on their first HIV treatment regimen either never have an undetectable viral load or their treatment stops working in the first year. During the second year on treatment, the chance of your therapy ceasing to work is about one in twenty and this declines further over the next decade to about a one-in-fifty chance of failure in any one year.

So, the longer youve been on a particular HIV therapy, the less likely it is to stop working. Almost everyone who goes on to a second or third regimen reduces their viral load to an undetectable level.

If someones treatment does not result in viral load becoming undetectable, this is usually because they are having problems taking their treatment as prescribed, i.e. they dont take all their pills at the right time, without missing doses. Occasionally missing a dose of medication is unlikely to cause your viral load to become detectable again, but frequently missing doses may lead to a detectable viral load and should be avoided.

If you are having problems sticking with your treatment, talk to your doctor and they may be able to find a drug combination that suits you better.

A Timeline Of Hiv Symptoms

What is HIV?

HIV is a virus that compromises the immune system. Theres currently no cure for it, but there are treatments available to reduce its effects on peoples lives.

In the majority of cases, once HIV infection takes hold, the virus stays in the body for life. However, unlike what may occur with infections by other types of viruses, HIV symptoms dont suddenly appear and peak overnight.

If left untreated, the disease progresses over time through three stages, each with its own set of possible symptoms and complications some severe.

Regular antiretroviral treatment can reduce HIV to undetectable levels in the blood. At undetectable levels, the virus wont progress to the later stages of HIV infection. In addition, the virus cant be transmitted to a partner during sex.

How Long Does It Take To See The Signs Of Hiv

Why its so hard to cure HIV/AIDS – Janet Iwasa

The signs and symptoms of HIV may first appear within two to four weeks of infection. The stage in which the symptoms appear is called the stage of acute HIV infection. The symptoms appear due to the resistance or fight of the immune system against HIV. In the initial stage, the virus multiplies rapidly and spreads throughout the body. It targets and destroys the CD4 cells . As a result, the level of HIV in the blood and the chances of transmission at this stage are very high. It is crucial to recognize the early signs and seek medical help, since early diagnosis and treatment of HIV gets the best results.

How Hiv Is Transmitted

HIV is not passed on easily from one person to another. The virus does not spread through the air like cold and flu viruses.

HIV lives in the blood and in some body fluids. To get HIV, 1 of these fluids from someone with HIV has to get into your blood.

The body fluids that contain enough HIV to infect someone are:

  • semen
  • vaginal fluids, including menstrual blood
  • breast milk
  • contact with animals or insects like mosquitoes

Does Hiv Viral Load Affect Getting Or Transmitting Hiv

Yes. Viral load is the amount of HIV in the blood of someone who has HIV. Taking HIV medicine daily as prescribed can make the viral load very lowso low that a test cant detect it .

People with HIV who take HIV medicine daily as prescribed and get and keep an undetectable viral load have effectively no risk of transmitting HIV to an HIV-negative partner through sex.

HIV medicine is a powerful tool for preventing sexual transmission of HIV. But it works only as long as the HIV-positive partner gets and keeps an undetectable viral load. Not everyone taking HIV medicine has an undetectable viral load. To stay undetectable, people with HIV must take HIV medicine every day as prescribed and visit their healthcare provider regularly to get a viral load test. Learn more.

To Prevent Hiv Infection Couples Try Testing Together

In other words, particular versions of the virus, with particular DNA sequences, are most likely to pass from a woman to a man. This reduces the chance an infection occurs during sex.

The restriction is less when women have sex with an HIV-positive man. And, most likely, reduced even further when men have sex with men. So the chance of an infection increases in both situations.

As HIV replicates inside a person, mutations are introduced into its DNA. This results in a large number of different HIV versions swarming about the body each with its own genetic code.

But when HIV is transmitted through sex, usually only a single version of the virus establishes a long-term infection. So the process is almost like a filter, letting only certain viruses through.

This made scientists wonder: Is there something special about the HIV versions making it through the filter?

To figure this out, a team at Microsoft Research and Emory University analyzed data from a decades-long study on HIV transmission between “discordant” heterosexual couples in Zambia. These are couples in which one person is HIV-positive and the other is HIV-negative.

Ways Hiv Cannot Be Spread

Can HIV/AIDS be on money paper?

HIV is not spread by:

  • Air or water
  • Mosquitoes, ticks or other insects
  • Saliva, tears, or sweat that is not mixed with the blood of a person with HIV
  • Shaking hands hugging sharing toilets sharing dishes, silverware, or drinking glasses or engaging in closed-mouth or social kissing with a person with HIV
  • Drinking fountains

How Is Hiv Spread From Person To Person

HIV can only be spread through specific activities. In the United States, the most common ways are:

  • Having vaginal or anal sex with someone who has HIV without using a condom or taking medicines to prevent or treat HIV. Anal sex is riskier than vaginal sex.
  • Sharing injection drug equipment , such as needles, with someone who has HIV.

Less common ways are:

HIV is spread only in extremely rare cases by:

  • Having oral sex. But in general, the chance that an HIV-negative person will get HIV from oral sex with an HIV-positive partner is extremely low.

Symptoms And Stages Of Hiv Infection

FAST FACTS

  • There are three stages of HIV infection. The symptoms vary in type and severity from person-to-person.
  • Stage 1 after initial infection can feel like flu but not everyone will experience this.
  • Stage 2 is when many people start to feel better and may last for 10 years or more. During this time a person may have no symptoms.
  • Stage 3 is when a persons immune system is very badly damaged and can no longer fight off serious infections and illnesses.
  • The earlier a person is diagnosed with HIV and starts treatment, the better their health will be over time.
  • Some people dont get any symptoms during stages 1 and 2, and may not know they have the virus, but they can still pass on HIV.

The signs of HIV infection can vary in type and severity from person-to-person, and some people may not have any symptoms for many years.

The stages below describe how HIV infection progresses in the body if it is left untreated. Without antiretroviral treatment for HIV, the virus replicates in the body and causes more and more damage to the immune system.

However with effective treatment, you can keep the virus under control and stop it from progressing. This is why its important to start treatment as soon as possible after testing positive.

People Think Its Easy To Contract Hiv Thats A Good Thing Right Maybe Not Guest Post By Jason Kerwin

    This is the fourteenth in our series of posts by students on the job market this year.People are afraid of HIV. Moreover, people around the world are convinced that the virus is easier to get than it actually is. The median person thinks that if you have unprotected sex with an HIV-positive person a single time, you will get HIV for sure. The truth is that its not nearly that easy to get HIV the medical literature estimates that the transmission rate is actually about 0.1% per sex act, or 10% per year.

    Great stuff! I’ve wanted to see precisely this paper for a while. I think it’s morally opprobrious that we exaggerate the risks to people, and it’s very interesting to also see that this backfires through the previously only theorized fatalism channel.

    I was 12 when magic Johnson came out that he wasHIV positive. I am now 37 and sex still scares me and I can honestly say I barely get any enjoyment out of it. This was helpful I’ll relax a little bit more

    my partner of six years is HIV positive,this has affected our sexual relationship and we do not have any child yet,because of his condition.he has been on hiv drug all this while and the VL shows 0.1%,can we make love without me contacting the virus?

    Hiv And Maternal Transmission

    A potential cure for HIV | The Economist

    HIV can be passed from mother to child during pregnancy, delivery, or through breastfeeding. If left untreated throughout these stages, there is a 15-45% chance of an HIV positive mother transmitting the virus to their child . However there are treatment options to prevent this from happening.

    If pregnancy occurs and there has been potential HIV exposure, ask a healthcare provider about getting tested for HIV as early as possible. Taking medications called antiretroviral therapy as prescribed can reduce the viral load so that the baby has a very low chance of contracting HIV .

    A person with HIV should not breastfeed their child, as breast milk can transmit HIV. Even if a person is taking ART and their viral loads are undetectable, they should still not breastfeed.

    How Do You Get Hiv

    HIV infection can occur in the following ways:

    • Unprotected sexual intercourse, especially receptive anal intercourse
    • Multiple sexual partners
    • Sexually transmitted diseases: Chlamydia and gonorrhea infections increase the HIV transmission risk by three times syphilis raises the transmission risk by seven times and genital herpes raises the infection risk by 25 times during an outbreak
    • Sharing IV needles or injections
    • Receiving HIV infected blood products
    • Needle-stick injuries
    • Maternal HIV infection : The risk of transmission can be reduced at birth by practices like cesarean delivery and prenatal antiretroviral therapy in the mother, and antiretroviral therapy in the newborn immediately after birth

    Hiv And Aids Diagnosis

    HIV tests check your blood or fluid from your mouth for antibodies that your body makes in response to the virus. You can take them at a doctorâs office, a community health center, a hospital, or at home.

    When you have HIV, your doctor will keep an eye on how much of the virus is in your system. You might hear them call it your âviral load.â Two things will tell them if your infection has become AIDS:

    • Your CD4 count. A person with a healthy immune system has 500 to 1,600 CD4 cells in a cubic millimeter of their blood. A person with AIDS has fewer than 200. This number is called your âCD4 count.â
    • AIDS-defining infections. These are also called opportunistic infections. These generally happen in people who have a CD4 count below 200. Viruses, bacteria, or fungi that donât usually make healthy people sick can cause these infections in someone with HIV or AIDS.

    How long it takes HIV to become AIDS is different for everyone. If you donât get treatment, it might take 10 to 15 years. With treatment, you may never have AIDS.
