What Is The Connection Between Hiv And Aids

When And Where Did Hiv Start In Humans

what is the connection between TB and HIV (is TB sign of hiv)

Studies of some of the earliest known samples of HIV provide clues about when it first appeared in humans and how it evolved. The first verified case of HIV is from a blood sample taken in 1959 from a man living in what is now Kinshasa in the Democratic Republic of Congo. The sample was retrospectively analysed and HIV detected. There are numerous earlier cases where patterns of deaths from common opportunistic infections, now known to be AIDS-defining, suggest that HIV was the cause, but this is the earliest incident where a blood sample can verify infection.9

How Are The Tb Tests Given

For a TB skin test, a health worker uses a small needle to put some fluid, called tuberculin, just under your skin. This is usually done on the lower inside part of your arm. After you get the test, you must return in 2 to 3 days to see if there is a reaction to the test. If there is a reaction, the size of the reaction is measured to determine if you have a positive result.

If you receive the TB blood test, a sample of your blood will be taken to do the test. Your health care worker will tell you how to get the results of your test.

You’re More Likely To Get Hiv If Your Partner Has Hiv And An Std

People with both HIV and an STD have more HIV in their semen or vaginal fluid. This makes it easier for a person with an STD or HIV to give the virus to others when having sex without a condom.

Remember, many people who have HIV don’t know it. It can take many years for symptoms to show up. That is why it is so important to use condoms during sex, or not to have sex at all.

How Stis Get Passed From One Person To Another

STIs get passed from one person to the next by condomless vaginal, anal, or yes, even oral sex . They can also be passed by sharing sex toys that havent been cleaned or any other exchange of genital fluids.

Things that can increase your risk of getting an STI include:

  • having sex without a condom or other barrier
  • changing your sexual partners often, or
  • having multiple sexual partners at once

Hiv Doesnt Always Progress To Stage 3

Hiv 101 dr susan gregorio

HIV is a virus, and AIDS is the condition the virus may cause. An HIV infection doesnt necessarily progress to stage 3. In fact, many people with HIV live for years without developing AIDS. Thanks to advances in treatment, a person living with HIV can expect to live a near-normal life span.

While a person can have an HIV infection without having AIDS, anyone diagnosed with AIDS has already contracted HIV. Because there is no cure, the HIV infection never goes away, even if AIDS never develops.

How Do People Get Hiv

HIV spreads when infected blood or body fluids enter the body. This can happen:

HIV also can pass from mother to child during pregnancy, childbirth, or breastfeeding.

HIV is NOT spread through:

  • pee, poop, spit, throw-up, or sweat
  • coughing or sneezing
  • sharing eating utensils or drinking glasses

Types Of Lymphoma Linked To Hiv

Most AIDS-related lymphomas are B cell NHL. HIV chronically stimulates B-cells, increases their rate of reproduction, and activates them.

Primary CNS lymphoma, which originates in the brain, accounts for almost half of all AIDS-related lymphoma. Most AIDS-related NHL is extranodal, which means that the disease is found in places outside of the lymph system. The most common places where NHL is located in this population are the gastrointestinal system, liver, heart, lungs, skin, and bone marrow.

What Are The Signs & Symptoms Of Hiv And Aids

When first infected with HIV, a person may have:

  • fever
  • increased number of infections
  • infections that are more severe than is typical

Without treatment, HIV can lead to a very weakened immune system and progress to AIDS. Illnesses that happen in AIDS are called “AIDS-defining conditions.”

AIDS-defining conditions include:

  • very fast and severe weight loss
  • a lung infection called pneumocystis pneumonia
  • Kaposi sarcoma
  • lymphoma

Lessons To Be Learned

The Connection Between Sudden Cardiac Death and People with HIV/AIDS

So why is it important to understand the association between HIV and other STIs? STIs are a major health concern in the Black community. More than half of reported primary- and secondary-syphilis cases occur among Black Americans. This means that Black Americans are particularly vulnerable to STIs simply because a higher percentage of people in the Black community are already living with STIs. However, it’s important to note that data could be skewed because different states have different reporting requirements for certain STIs. That means private physicians may not have to report specific STIs in some states, whereas public health centers–where many Black Americans get their care–must report data as part of program requirements.

HIV-prevention messages should be targeted toward communities that have high levels of STI rates, conference researchers said. HIV testing can also be increased in such communities because people with other STIs are at an increased risk of acquiring HIV. This makes using condoms even more important for those who don’t know their partner’s HIV status. Treatment for STIs can a person’s likelihood of transmitting HIV.

People living with HIV/AIDS should also be careful not to become infected with other STIs. Some HIV-positive individuals forsake condoms when they have sex with other people with HIV. However, this leaves you vulnerable to other STIs, conference participants said, unless you and your partner have both tested negative for them.

Why Do People Often Confuse Hiv And Aids And Why Is This Harmful

Dr Win-Leung Siu explains that history plays a large part in misconceptions and confusion surrounding HIV and AIDS.

“When they first appeared in significant numbers in the 1970s-80s, there was very little treatment. If you were diagnosed with HIV, it was probable you would develop, and perhaps die from, AIDS. This led to the belief that HIV was inevitably going to result in early death. I think it’s key to point out that, as with many illnesses, doctors would recognise the illness before they discover the cause. In this case, they were aware of AIDS but not so much the virus HIV. So, during the early days of diagnosis, doctors would recognise the illness we now call AIDs first before making the connection to HIV.”

The misconceptions around the conditions often prevent those concerned about their health from getting tested. As long as there is shame attached to being HIV positive, cases will go undetected for longer than necessary. While society has progressed, there needs to be more education surrounding living with HIV, so people understand that it can be managed on a daily basis. Myths are still very prevalent, suggesting that being diagnosed with HIV is a death sentence, but that isn’t the case anymore.

How Is Hiv Treated And What Can Happen If It Goes Untreated

Unfortunately, there is still no absolute cure for HIV. However, medication is now available to suppress the virus to an extent where you can live a full life comparable with someone without HIV.

This medication can reduce or, as we’ve heard, completely eradicate your chances of spreading the virus.

Firstly, if you think you have been exposed to HIV, you can take post-exposure prophylaxis medicine that can hugely reduce the chance of you becoming infected. This medication must be started within 72 of coming into contact with the virus and can be prescribed by A& E departments and sexual health clinics.

PEP involves taking HIV treatment every day for one month.

There is also PrEP, which stands for pre-exposure prophylaxis. If taken correctly, this daily pill can protect you from HIV. It’s a combination of two drugs used to treat HIV and protects your negative HIV status. With this medication, you can have a far lower level of concern about a sexual partner being HIV positive.

PrEP only protects against HIV, not other STIs, so you still need to take other precautions. However, it is a good idea if you are HIV negative, want to have control of your sexual health and are having sexual encounters that put you at risk of being exposed to HIV.

HIV can quickly become resistant to medication, so a combination of drugs is used to fight the infection. You might be able to get these drugs in a single pill, but might have to take four pills a day.

How Do I Know If I Have Hiv

The only way to know for sure if you have HIV is to get tested. Testing is relatively simple. You can ask your health care provider for an HIV test. Many medical clinics, substance abuse programs, community health centers, and hospitals offer them too. You can also buy a home testing kit at a pharmacy or online.

To find an HIV testing location near you, use the HIV Services Locator.

HIV self-testing is also an option. Self-testing allows people to take an HIV test and find out their result in their own home or other private location. You can buy a self-test kit at a pharmacy or online. Some health departments or community-based organizations also provide self-test kits for free.

Read the U.S. Food and Drug Administrations fact sheet on the OraQuick In-Home HIV Test, the only FDA-approved in-home HIV test.

The coronavirus pandemic has made it more difficult for some people to access traditional places where HIV testing is provided. Self-testing allows people to get tested for HIV while still following stay-at-home orders and social distancing practices. Ask your local health department or HIV service organization if they offer self-testing kits.

Why Is It Important To Know If I Am Infected With Both Tb And Hiv

PPT

If you have HIV, it is important to know if you have TB infection because HIV weakens the immune system. When a persons immune system is weak, latent TB infection can quickly progress to TB disease. If you have HIV, it is very important to get a TB test.

If you have latent TB infection or TB disease, and you do not know your HIV status, you should get an HIV test. This will help your physician know how to treat both your TB and HIV infections.

Treatment And Life Expectancy

If HIV develops into stage 3 HIV, life expectancy drops significantly. Its difficult to repair damage to the immune system at this point. Infections and other conditions, such as certain cancers, resulting from severe immune system impairment are common. However, with successful antiretroviral therapy and some immune system recovery, many people with stage 3 HIV live long lives.

With todays treatments for HIV infection, people can live with HIV and never have AIDS develop. Its also important to note that successful antiretroviral treatment and a sustained undetectable viral load greatly lowers the risk of transmitting the virus to a partner.

Hiv Can Be Transmitted From Person To Person

Because HIV is a virus, it can be transmitted between people just like many other viruses. AIDS, on the other hand, is a condition a person acquires only after theyve contracted HIV.

The virus is transmitted from one person to another through the exchange of bodily fluids. Most commonly, HIV is transmitted through sex without condoms or shared needles. Less so, a mother can transmit the virus to their child during pregnancy.

Std Statistics In The Us

According to the Centers for Disease Control and Prevention , nearly 20 million new STD infections occur every year, accounting for almost $16 billion in healthcare costs. In 2017, the bulk of infections were primarily constrained to three diseases:

  • Chlamydia: 1,708,569 infections at a rate of 529 per 100,000
  • Gonorrhea: 555,608 infections at a rate of 172 per 100,000
  • Syphilis : 30,644 infections at a rate of 9 per 100,000

The rate of STD infections is particularly high among gay and bisexual men who, not surprisingly, account for the highest rate of HIV infections in the U.S.

Gay and bisexual men account for almost all primary and secondary syphilis cases.

To this end, If you are a sexually active gay or bisexual man, you should be tested for syphilis, chlamydia, gonorrhea, and HIV at least once a year. More frequent STD testing, between every three to six months, is recommended for gay or bisexual men at high risk, especially those who have multiple sex partners, use recreational drugs, or practice condomless sex.

What If My Tb Test Is Negative

The TB and HIV AIDS connection

A negative test usually means you are not infected with TB germs. However, the tests may be falsely negative if you have a weakened immune system or if you were infected recently. This is because it usually takes 2 to 8 weeks after exposure to a person with TB disease for your immune system to produce a response to the test. If you have a negative result and it has been less than 8 weeks since you were last exposed to TB disease, you may need to get a second test. Your health care worker will let you know if you need another test.

Some people with HIV infection will have a negative test result even if they are infected with TB germs. This is because the immune system, which causes the reaction to the tests, is not working properly. People with HIV who have a negative TB test may need further medical evaluation, especially if they have symptoms of TB disease.

Hiv Is An Infection That Can Lead To Aids

HIV stands for Human Immunodeficiency Virus. Its a virus that breaks down certain cells in your immune system . When HIV damages your immune system, its easier to get really sick and even die from infections that your body could normally fight off.

About 1.1 million people in the U.S. are living with HIV, and more than 38,000 new infections happen every year. Most people with HIV dont have any symptoms for many years and feel totally fine, so they might not even know they have it.

Once you have HIV, the virus stays in your body for life. Theres no cure for HIV, but medicines can help you stay healthy. HIV medicine lowers or even stops your chances of spreading the virus to other people. Studies show that using HIV treatment as directed can lower the amount of HIV in your blood so much that it might not even show up on a test when this happens, you cant transmit HIV through sex.Treatment is really important . Without treatment, HIV can lead to AIDS. But with medicine, people with HIV can live long, healthy lives and stop the spread of HIV to others.

Stis And Hiv: The Tie And Why It Matters

It’s no secret that connections exist between HIV and other sexually transmitted infections , but researchers are pushing for more coordination to reduce the incidence of all such conditions.

Two sessions at AIDS 2012 looked at the correlations between HIV and other STIs. One, called “Dangerous Liaisons: HIV and Sexually Transmitted Infections,” highlighted research showing that many people diagnosed with other STIs are often later diagnosed or concurrently diagnosed with HIV. In fact, according to the Centers for Disease Control and Prevention , people infected with an STI are two to five times more likely to become infected with HIV after exposure to the virus than people who are not infected by another STI. The other session, “Enhancing STI Services for HIV Prevention,” looked at the value of screening people diagnosed with any STIs for HIV and targeting prevention messages toward that group.

Causes Of Hiv Infection

HIV is found in the body fluids of an infected person. This includes semen, vaginal and anal fluids, blood and breast milk.

It’s a fragile virus and does not survive outside the body for long.

HIV cannot be transmitted through sweat, urine or saliva.

The most common way of getting HIV in the UK is through having anal or vaginal sex without a condom.

Other ways of getting HIV include:

  • sharing needles, syringes or other injecting equipment
  • transmission from mother to baby during pregnancy, birth or breastfeeding

The chance of getting HIV through oral sex is very low and will be dependent on many things, such as whether you receive or give oral sex and the oral hygiene of the person giving the oral sex.

The Risk Of Cancer For Hiv Patients

PPT

Since the development of highly active antiretroviral therapies , HIV patients are living much longer. The downside to this positive news is that they are living longer with a decreased immune system that allows the opportunity for cancer to develop. In the past, it has been estimated that as many as 40% of HIV/AIDS patients may develop an AIDS-related cancer.

In the early days of the AIDS epidemic, certain types of lymphoma occurred thousands of times more frequently in HIV patients than in the rest of the population. Since the introduction of HAART in 1996, these rates have decreased significantly but infection with the HIV continues to be a risk factor for NHL. Study results are unclear as to the effect that HAART has had on the rates of Hodgkin lymphoma.

The risk of NHL is the same across all HIV populations, regardless of how the disease was contracted.

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.
