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
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.
Can Hiv Symptoms Show Up After Five Years
However if they remain without treatment, after a few years they may begin to experience some mild symptoms related to HIV, such as skin rashes, fatigue, night sweats, slight weight loss, mouth ulcers, and fungal skin and nail infections. These could show up five years after infection, or it could take longer.

What Is The Difference Between An Std And Sti
The term STD is often used interchangeably with the term sexually transmitted infection . But despite this common misconception, STDs and STIs arent exactly the same. Each term has a specific meaning:
- STI. An STI is a sexually transmitted infection and doesnt cause any symptoms. Instead, an STI refers to the presence of the virus, bacteria, or other pathogens in your body.
- STD. An STD is a sexually transmitted disease, which does cause symptoms. It happens when the pathogens in your body have led to the cell damage that produces symptoms.
Put simply, an infection just means the presence of the pathogen is in your body, while a disease means youre having symptoms. A condition is only considered an STD if there are symptoms.
This might seem like a small difference, but the distinction is important. This is especially true for STIs that rarely cause symptoms, like chlamydia or gonorrhea. For many people, these STIs wont ever progress to STDs.
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.

Rash Related To Medication
While rash can be caused by HIV co-infections, it can also be caused by medication. Some drugs used to treat HIV or other conditions can cause a rash.
This type of rash usually appears within a week or 2 weeks of starting a new medication. Sometimes the rash will clear up on its own. If it doesnt, a change in medications may be needed.
Rash due to an allergic reaction to medication can be serious.
Other symptoms of an allergic reaction include:
- trouble breathing or swallowing
- dizziness
- fever
Stevens-Johnson syndrome is a rare allergic reaction to HIV medication. Symptoms include fever and swelling of the face and tongue. A blistering rash, which can involve the skin and mucous membranes, appears and spreads quickly.
When 30 percent of the skin is affected, its called toxic epidermal necrolysis, which is a life threatening condition. If this develops, emergency medical care is needed.
While rash can be linked with HIV or HIV medications, its important to keep in mind that rashes are common and can have many other causes.
Prevention Of Acute Hiv Infection
There are ways to minimize the risk of contracting HIV, or passing the infection on to other people:
- Practice safe sex: use condoms during all types of sexual contact and limit the number of partners
- Practice safe needle use: use only sterile needles and equipment if injecting substances. Safe needle use should also be observed by healthcare workers and tattooists
- Get diagnosed early, which can inform choices such as treatment and behavior toward other people
Anyone who is sexually active is recommended to get tested for HIV and other sexually transmitted diseases at least once a year. Any positive results should be disclosed to sexual partners so precautions can be taken. More frequent testing is recommended for anyone in a high risk group, such as someone who:
- Is in a relationship with a person who is HIV-positive
- Has multiple sexual partners

Disorders Of The Esophagus
The GI tract is a long tube with one entrance and one exit , and problems can occur in any section on the way down. The esophagus is the part of the tube between the mouth and the stomach. The muscles of the esophagus contract and relax to propel food down. A muscular valve at the base of the esophagus closes off the stomach so that its acidic contents can’t leak back up into the esophagus.
Heartburn — a burning sensation behind the center of the ribcage — occurs when stomach contents travel back up the esophagus. If you experience heartburn, it usually happens thirty to sixty minutes after eating and is sometimes accompanied by a sour taste in the mouth. Heartburn can be prevented by waiting at least three hours after meals to lie down, by elevating the head of the bed or using extra pillows in bed, and by avoiding spicy or acidic foods. Other lifestyle changes to help prevent heartburn include maintaining a healthy weight and avoiding tight belts or pants.
Frequent heartburn is a side effect of some HIV medications. It may also be a sign of gastroesophageal reflux disease, called GERD for short. GERD can damage the lining of the esophagus and lead to other complications. Frequent heartburn should be discussed with your healthcare provider, as inexpensive, over-the-counter treatments are available. Further testing by your provider, including looking down the esophagus with a camera , may be necessary if the symptoms don’t go away.

What Are The Treatments For Hiv/aids
There is no cure for HIV infection, but it can be treated with medicines. This is called antiretroviral therapy . ART can make HIV infection a manageable chronic condition. It also reduces the risk of spreading the virus to others.
Most people with HIV live long and healthy lives if they get and stay on ART. It’s also important to take care of yourself. Making sure that you have the support you need, living a healthy lifestyle, and getting regular medical care can help you enjoy a better quality of life.
Aids Is The Final Stage
Controlling HIV with medications is crucial to both maintaining quality of life and helping prevent progression of the disease. Stage 3 HIV, also known as AIDS, develops when HIV has significantly weakened the immune system.
According to the CDC National Prevention Information Network, CD4 levels give one indication that HIV has progressed to its final stage. CD4 levels decreasing below 200 cells per cubic millimeter of blood is considered a sign of AIDS. A normal range is considered 500 to 1,600 cells/mm3.
AIDS can be diagnosed with a blood test to measure CD4. Sometimes its also determined simply by a persons overall health. In particular, an infection thats rare in people who dont have HIV may indicate AIDS. Symptoms of AIDS include:
- persistent high fevers of over 100°F
- pneumonia
AIDS is the final stage of HIV. According to AIDSinfo, it takes at least 10 years without treatment for most people with HIV to develop AIDS.
At that point, the body is susceptible to a wide range of infections and cant effectively fight them off. Medical intervention is necessary to treat AIDS-related illnesses or complications that can otherwise be fatal. Without treatments, the CDC estimates the average survival rate to be three years once AIDS is diagnosed. Depending on the severity of their condition, a persons outlook may be significantly shorter.

Where To Get Tested For Hiv
Getting an HIV test is easy. Tests for HIV and other STIs are confidential and available from your local doctor , or a sexual and reproductive health clinic.
It is a good idea to have some pre-test counselling. Before the test, talk with your doctor, nurse, or peer tester about any concerns, your level of risk, whether you are likely to be HIV-positive and what a positive result may mean.
Listening To The Gi Tract: Clues To Three Dangerous Toxicities Of Hiv Medications
The medication side effects described above can get in the way of good adherence and may disrupt your daily life. But there are some toxicities associated with HIV medications that can be life-threatening. Your first clue to these serious problems may be GI symptoms, so your best bet is to report any and all GI side effects to your provider.
Lactic Acidosis
Lactic acidosis is a condition associated with NRTIs, especially Videx and Zerit , but Retrovir as well. NRTIs damage mitochondria, which are inside all human cells and use oxygen, fat, and sugar to produce energy for the cells. Mitochondrial damage leads to excess lactate production, which drives up the level of lactic acid in the blood. Lactic acidosis is more common in women, and it may be accompanied by liver abnormalities, including fatty liver. Symptoms of lactic acidosis may include decreased appetite, nausea, vomiting, or abdominal pain, although many people who experience the condition may not experience or notice the symptoms right away. Your provider can run tests to check the level of lactate in your blood if he or she suspects lactic acidosis.
Pancreatitis
Some HIV medications can cause pancreatitis, an inflammation of the pancreas that is life-threatening. This condition most frequently occurs with Videx , Bactrim, and pentamidine . Pancreatitis can cause abdominal pain which radiates to the back and is worst after eating, sometimes accompanied by nausea and vomiting.

How Does Acute Hiv Affect The Body
Once a person contracts HIV, the acute infection takes place immediately.
Symptoms of the acute infection may take place days to weeks after the virus has been contracted. During this time, the virus is multiplying rapidly in the body, unchecked.
This initial HIV stage can result in flu-like symptoms. Examples of these symptoms include:
- myalgias, or muscle pain
However, not all people with HIV experience initial flu-like symptoms.
The flu symptoms are due to the increase of copies of HIV and widespread infection in the body. During this time, the amount of CD4 cells starts to fall very quickly. The immune system then kicks in, causing CD4 levels to rise once again. However, the CD4 levels may not return to their pre-HIV height.
In addition to potentially causing symptoms, the acute stage is when people with HIV have the greatest chance of transmitting the virus to others. This is because HIV levels are very high at this time. The acute stage typically lasts between several weeks and months.
Spreading Hiv And Stds
HIV and STDs are both contracted by having unprotected sexual contact of any kind. This includes vaginal, anal, and oral sex.
But sexual contact isnt the only way to contract an STD or HIV. Pathogens like HIV, hepatitis B, and hepatitis C can also be spread by sharing needles or other drug paraphernalia.
Birthing parents can also pass HIV and some STDs on to babies while pregnant, during delivery, or through breastfeeding. For example, chlamydia and gonorrhea are two types of pathogens that can be passed to a baby during delivery.

Are People With Hiv At Risk For Kidney Disease
The risk factors for kidney disease in people with HIV include all those listed above. In addition, poorly controlled HIV infection and coinfection with the hepatitis C virus increase the risk of kidney disease in people with HIV.
Antiretroviral therapy is the use of HIV medicines to treat HIV. People on ART take a combination of HIV medicines every day. HIV medicines are recommended for everyone who has HIV. Some HIV medicines can affect the kidneys. Health care providers carefully consider the risk of kidney damage when recommending specific HIV medicines to include in an HIV treatment regimen. If a person with HIV shows signs of kidney disease, their health care provider may adjust the dose of their HIV medicines or change which HIV medicines are included in their treatment regimen.
Hiv Transmission In Australia
In Australia, HIV is commonly transmitted through:
- Unprotected anal or vaginal sex .
- Sharing any needles, syringes, or other injecting equipment.
- From mother to child during pregnancy, childbirth, or breastfeeding This can occur when the mother doesnt know she is HIV-positive, or is not on effective treatment.
- Tattooing or other procedures that involve unsterile or reused equipment.
- Needle stick injuries.
HIV is not transmitted by:
- kissing, hugging, massaging, mutual masturbation and other body contact
- social interaction
- sharing food, dishes, utensils, drinking glasses
- air, breath, or being coughed or sneezed on
- mosquito, insect or animal bites
- use of communal facilities .
It is perfectly safe to consume food and drinks prepared by someone who is HIV-positive even if theyre not receiving treatment.
People with HIV who are on treatment and achieve and maintain an undetectable HIV viral load cannot transmit HIV sexually.

Get Tested Regularly If You Are At Greater Risk Of Hiv
If you are at greater risk of HIV get tested regularly.
Gay, bisexual, trans and other men who have sex with men should get tested every 3 months . This may vary depending on how many sexual partners you have during the year.
Talk with your doctor or sexual health specialist for advice. They can also provide information about how to reduce your risk for HIV and other STIs.

Contracting other sexually transmitted diseases can significantly increase the risk of getting HIV. For instance, some STDs like syphilis and herpes cause skin lesions that make it easier for HIV to enter the body.
STDs may also cause inflammation, which is something that is triggered by the body’s immune system. HIV preferentially infects defensive white blood cells, so when there are more of them around, it’s easier to contract HIV.
Having an STD like gonorrhea or syphilis means that you’ve engaged in unprotected sex, a key risk factor for HIV. So if you have been diagnosed with an STD, talk to your healthcare provider about how you can reduce your HIV risk.

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.
