How Is Hiv/aids Transmitted
HIV is spread most commonly by sexual contact with an infected partner. The virus enters the body through the lining of the vagina, vulva, penis, rectum, or mouth during sexual activity.
HIV may also be spread through contact with infected blood. However, due to the screening of blood for evidence of HIV infection in the U.S., the risk of acquiring HIV from blood transfusions is extremely low.
HIV is often spread by sharing needles, syringes, or drug use equipment with someone who is infected with the virus. Transmission from patient to healthcare worker, or vice-versa through accidental sticks with contaminated needles or other medical instruments, is rare.
HIV also can be spread to babies born to, or breastfed by, mothers infected with the virus.
|HIV/AIDS cannot be spread through:
Can Hiv Be Prevented Or Avoided
The best way to prevent HIV is to not have sex with a person who has HIV, or share a needle with a person who has HIV. However, there is also a medicine called PrEP that people can take before coming into contact with HIV that can prevent them from getting an HIV infection.
PrEP stands for pre-exposure prophylaxis. It is for people who are at long-term risk of getting HIV either through sexual activity or by injecting drugs. If youre taking PrEP and come into contact with HIV, the medicine makes it difficult for HIV to develop inside your body.
Other ways to prevent HIV include:
- When you have sex, practice safer sex by using a condom. The best condom is a male latex condom. A female condom is not as effective but does offer some protection.
- Do not share needles and syringes.
- Never let someone elses blood, semen, urine, vaginal fluid, or feces get into your anus, vagina, or mouth.
Integrase Strand Transfer Inhibitors
Integrase inhibitors stop the action of integrase. Integrase is a viral enzyme that HIV uses to infect T cells by putting HIV DNA into the human DNA.
Integrase inhibitors are usually among the first HIV drugs used in people who have recently contracted HIV. This is because they work well and have minimal side effects.
The following drugs are integrase inhibitors:
- tenofovir disoproxil fumarate
As a stand-alone drug, tenofovir alafenamide fumarate has received full FDA approval to treat chronic hepatitis B but only tentative FDA approval to treat HIV. A person with HIV who takes tenofovir alafenamide fumarate will likely receive it as part of a combination HIV drug, not as a stand-alone drug.
Tenofovir disoproxil fumarate, emtricitabine, and lamivudine can treat hepatitis B as well.
Zidovudine was the first FDA-approved HIV drug. Its also known as azidothymidine or AZT. Zidovudine is rarely used in adults now. Its mainly given to babies born to HIV-positive mothers as a form of post-exposure prophylaxis .

Symptoms Of Hiv In The Early Stage
HIV is a progressive disease which means that in most cases, it deteriorates as time goes on from the first infection. Some of the symptoms that come up in the early stages are mild, and in most cases, they can be mistaken for common diseases. Once the HIV gets entry into the body, most people will suffer from the short flu which in some cases can turn severe. The flu is the body’s natural way of responding to the intrusion of the virus, and it can be accompanied with other symptoms such as fever, fatigue, headache, skin rashes, sore throat and weight loss, which are discussed below.
Who Is At Risk Of Acute Hiv Infection
HIV can affect people of any age, sexual orientation or race, in any part of the world. However, certain groups of people are more at risk of contracting HIV than others. These can include people who:
- Have unprotected sex, particularly anal sex, with multiple partners
- when injecting substances
HIV can be spread in the following ways:
- Contact with infected blood
- Contact with infected vaginal and/or rectal fluids
- From mother to child during pregnancy or birth if the pregnant woman has HIV
- Less commonly, during breastfeeding if the breastfeeding woman has HIV and is not on antiretroviral treatment
- Sharing needles, syringes or drug preparation equipment with someone who has HIV
Other physical contact, such as hand-holding, kissing or hugging, does not transfer HIV..

What Are The Symptoms Of Later Hiv
As HIV weakens someones immune system, they may experience signs of other illnesses:
- weight loss
- an increase in herpes or cold sore outbreaks
- swollen glands in the groin, neck or armpit
- long-lasting diarrhoea
But remember: people who dont have HIV can also get any of these they can be the signs of other illnesses.
A weakened immune system may leave someone more open to serious infections such as:
What Are The Symptoms Of Hiv/aids
Some people may develop a flu-like illness within a month after exposure to the HIV virus. But many people do not develop any symptoms at all when they first become infected. In addition, the symptoms that do appear, which usually disappear within a week to a month, are often mistaken for those of another viral infection. These may include:
Enlarged lymph nodes
Persistent or severe symptoms may not surface for 10 years or more after HIV first enters the body in adults, or within 2 years in children born with an HIV infection. This “asymptomatic” period of the infection is highly variable from person to person. But, during the asymptomatic period, HIV is actively infecting and killing cells of the immune system. Its most obvious effect is a decline in the blood levels of CD4+ T cells a key immune system infection fighter. The virus initially disables or destroys these cells without causing symptoms.
As the immune system deteriorates, complications begin to surface. The following are the most common complications, or symptoms, of AIDS. However, each individual may experience symptoms differently. Symptoms may include:
Some people develop frequent and severe herpes infections that cause mouth, genital, or anal sores, or a painful nerve disease known as shingles. Children may have delayed development or failure to thrive.

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
How Long After A Possible Exposure Should I Be Tested For Hiv
It takes the human body three to six months to seroconvert, or recognize the HIV virus in such a way that it would appear positive in a blood test. The amount of time between transmission and seroconversion is called the window period. For the most accurate results, it is best to wait until the three-to-six month window period has passed to get tested.

How Long Does It Take To See The Signs Of Hiv
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 To Tell If Symptoms Are Hiv
There are three types of HIV tests:
- An NAT involves drawing blood from a vein. It can tell if you have HIV or how much virus is present in your blood. While an NAT can detect HIV sooner than other types of tests, this test is very expensive and not routinely used for screening individuals unless they recently had a high-risk exposure, or a possible exposure and have early symptoms of HIV infection. This test takes several days for results to come back.
- An antigen/antibody test is recommended for testing done in labs and is now common in the United States. It involves drawing blood from a vein, and results take several days to come back. There is also a rapid antigen/antibody test available that is done with a finger prick and takes 30 minutes or less to get results.
- HIV antibody tests only look for antibodies to HIV in your blood or oral fluid. In general, antibody tests that use blood from a vein can detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid. Antibody tests can detect an HIV infection 23 to 90 days after exposure. Most rapid tests and the only currently approved HIV self-test are antibody tests. They take 20 minutes or less to provide results.
Keep in mind, any positive result would necessitate a second test to confirm it. The only test that would not require a second confirmatory test is the NAT.
What Are The Signs And Symptoms Of Hiv
No two people with HIV will have the same symptoms, and some may not have any at all. But the infection can cause some common changes over time.
In the first few weeks: These first, flu-like symptoms happen because your body is reacting to HIV. Your immune system is trying to fight it off. The symptoms at this stage can include:
- Aches and pains in muscles and joints
Keep in mind that even if you have these symptoms, that doesnât automatically mean you are HIV-positive. Many different illnesses can cause these problems. Talk to a doctor or an HIV testing facility if you think you might be infected.
At this early stage of HIV infection, itâs important to know that you may not get accurate results from an HIV test. It can take 3-12 weeks for enough signs of the virus to show up on routine tests for the infection, which measure antibodies against HIV. A new kind of screening, called a nucleic acid test, can detect the virus itself during this early stage, but itâs expensive and not usually used for routine HIV testing.
Let the testing site or your doctor know if you think you might be recently infected. Also, be sure to use a condom every time you have sex, and take other steps to prevent spreading the virus.
After years with untreated HIV, youâre likely to get infections caused by bacteria, viruses, or fungi that your body is no longer strong enough to fight off. They can be a sign that your infection has gone from HIV to AIDS. You might have:
- Weight loss

What Should I Do If I Think I Could Have Hiv
Only an HIV test can tell you whether you have HIV.
Try not to guess based on any symptoms you may or may not have, or on the HIV status of a person you have had sex with.
If you test, tell whoever tests you if youve recently taken risks or had symptoms similar to seroconversion illness, as this will affect the kind of HIV test you should have.
To be on the safe side, and until you know your test result, use condoms to protect anyone you have sex with.

Days To 20 Years After Exposure
The chronic stage of infection occurs once the immune system brings the virus under control. During this phase, HIV will go into hiding, where it resides in various cells and tissues throughout the body in a dormant state known as latency. HIV latency can persist without symptoms for 10 years or more, although some people may experience signs within a year or two.
During the early chronic phase, lymphadenopathy may be the only notable sign of an HIV infection. In some cases, the glands may be visibly enlarged and reach up to an inch or more in size. If the condition persists for more than three months, its referred to as persistent generalized lymphadenopathy .
Even during latency, the virus will multiple imperceptibly and gradually deplete immune cells known as CD4 T-cells. As immune deficiency develops, a number of nonspecific symptoms are likely to appear, including:
- Oral candidiasis , a fungal infection that causes the formation of creamy, white lesions on the sides of the tongue and lining of the mouth
- Unexplained fevers and drenching night sweats that soak through bedsheets and nightclothes
- Severe, uncontrolled diarrhea that lasts for more than three days
Each of these symptoms is commonly seen in persons with immune deficiency. They may, in some cases, be caused by HIV itself or by an infection that has yet to be diagnosed.

The Incubation Period Of Common Stds
After unprotected sex or when you discover a strange symptom in your pubic area, you may wonder about your risks of getting a sexually transmitted disease . Below, you will find a few guidelines for how long it usually takes for STD symptoms to show up after exposure.
This is the STD incubation periodthe length of time between infection and when symptoms appear. Knowing them will help you determine if you have an STD and take appropriate action.
The Most Common Symptoms Of Seroconversion Are:
- sore throat
- rash over the body.
Seroconversion is a sign that the immune system is reacting to the presence of the virus in the body. Its also the point at which the body produces antibodies to HIV. Once seroconversion has happened, an HIV test will detect antibodies and give a positive result.
Seroconversion illness happens to most people shortly after infection. It can be severe enough to put someone in hospital or so mild that its mistaken for something like flu although a blocked or runny nose is not usually a symptom.
If you do have HIV, your body fluids are highly infectious during the early weeks and months after transmission. However, once youre on effective treatment and your viral load becomes undetectable you cannot pass on HIV.
It can take up to six months from starting treatment to become undetectable.

How Does The Hiv Test Work
There are three different kinds of HIV test:
Stage : Clinical Latency
In this stage, the virus still multiplies, but at very low levels. People in this stage may not feel sick or have any symptoms. This stage is also called chronic HIV infection.
Without HIV treatment, people can stay in this stage for 10 or 15 years, but some move through this stage faster.
If you take HIV medicine every day, exactly as prescribed and get and keep an undetectable viral load, you can protect your health and have effectively no risk of transmitting HIV to your sexual partner.
But if your viral load is detectable, you can transmit HIV during this stage, even when you have no symptoms. Its important to see your health care provider regularly to get your viral load checked.

Lack Of Symptoms In Early Stages
ARS is common once a person has HIV. Still, this isnt the case for everyone. Some people have HIV for years before they know they have it. According to HIV.gov, symptoms of HIV may not appear for a decade or longer. This doesnt mean that cases of HIV without symptoms are less serious. Also, a person who doesnt experience symptoms could still transmit HIV to others.
Symptoms in early HIV tend to appear if the rate of cell destruction is high. Not having symptoms can mean that not as many CD4 cells, a type of white blood cell, are killed early on in the disease. Even though a person has no symptoms, they still have the virus. Thats why regular HIV testing is critical to prevent transmission. Its also important to understand the difference between a CD4 count and a viral load.
