Did Hiv Start In Africa
Using the earliest known sample of HIV, scientists have been able to create a ‘family-tree’ ancestry of HIV transmission, allowing them to discover where HIV started.
Their studies concluded that the first transmission of SIV to HIV in humans took place around 1920 in Kinshasa in the Democratic Republic of Congo .10
The same area is known for having the most genetic diversity in HIV strains in the world, reflecting the number of different times SIV was passed to humans. Many of the first cases of AIDS were recorded there too.
How Could You Get Hiv From Contact With Blood
The risk of HIV transmission through blood comes when the person has a detectable viral load and their blood enters another persons body or comes into contact with a mucous membrane. These are parts of the body with wet, absorbent skin such as the:
- inside of the anus
Theres also a risk if blood from a person who has a detectable viral load comes into contact with a cut or broken skin, giving HIV a way through the skin and into someones bloodstream. If blood gets onto skin that isnt broken, there is no risk.
In a medical setting, its possible for HIV to be transmitted by someone accidentally cutting themselves with a blade or needle they have used to treat a person living with HIV.
This is called a needlestick injury. The risk of being infected in this way is very low. However, if someone thinks they have been exposed to HIV through a needlestick injury, post-exposure prophylaxis may be an option.
How Can I Make Sure I Dont Give Hiv To Anyone During Sex
If you find out that you have HIV, try to stay calm. People living with HIV can have normal, healthy relationships and sex lives. But its important to take precautions to help your partner stay HIV-free.
There are a few ways that you can avoid giving HIV to other people:
Always use condoms when you have vaginal and anal sex.
Start treatment for HIV as soon as possible, and keep taking your HIV medicine. When you take it correctly, HIV treatment can lower or even stop your chances of spreading the virus to your sexual partners .
Theres a daily pill your partner can take to lower the risk of getting HIV, called PrEP.
Dont share needles for shooting drugs, piercings, or tattoos.
Get tested and treated for other STDs besides HIV regularly. Having other STDs makes it easier for you to spread HIV to others.
If you test positive for HIV, its important to tell your sexual partners about it so they can be tested, too. Even if youre really careful to not spread HIV, be honest with your future partners about your status so you can both be informed and help each other stay healthy.

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:
- From mother to child during pregnancy, birth, or breastfeeding. However, the use of HIV medicines and other strategies have helped lower the risk of mother-to-child transmission of HIV to 1% or less in the United States.
- Getting stuck with an HIV-contaminated needle or other sharp object. This is a risk mainly for health care workers. The risk is very low.
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.
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.

What Is Pep And How Does It Prevent Hiv
PEP stands for post-exposure prophylaxis. Its a series of pills you start taking after youve been exposed to HIV that lowers your chances of getting HIV. You have to start PEP within 72 hours , after you were exposed to HIV for it to work. The sooner you start it, the better. Every hour counts, so if you think you were exposed to HIV, call your nurse or doctor or go to the emergency room right away. PEP is only for emergencies it doesnt take the place of using condoms or PrEP. Read more about PEP.
Make A Plan To Prevent The Spread Of Hiv
Protection against HIV and other sexually transmitted infections isnt one size fits all. Whether youre HIV negative or positive, you can make a plan to #PlaySure to prevent the spread of HIV. People who are on HIV treatment and maintain an undetectable viral load do not transmit HIV. People who take daily PrEP have a very low risk of acquiring HIV.
Read a summary of the New York City Ending the Epidemic Plan .
What is the main goal?
The NYC Health Department is working to reduce the number of new infections in the City to fewer than 600 in 2020. This target aligns with New York States goal of reducing new statewide infections to fewer than 750 in 2020.
How was the strategy developed?
The NYC Health Department consulted with stakeholders and advocates in the community and worked with the HIV/AIDS Services Administration , City Hall and City Council, and the Centers for Disease Control and Prevention to develop the EtE strategy. The NYC Health Department also collaborated with the NYS Department of Health to help develop their plan to end the statewide epidemic of HIV/AIDS.
Since the NYC Health Department has a history of robust and innovative programming to prevent and treat HIV/AIDS, the EtE strategy was designed to build upon these core activities to address perceived gaps and leverage exciting new biomedical prevention technologies.
How can New Yorkers learn more?
Three community meetings have already taken place. These slides were presented at those events:
Also Check: Can Undetectable Hiv Be Transmitted
Can Hiv Be Transmitted Through Blood Transfusions
Yes but this is very rare. In the unlikely event that a person who is HIV-positive donates blood products that are not tested, the person who receives the blood product is likely to develop an HIV infection too.
If youre thinking about donating blood but are not sure about your HIV status, you can request an HIV test in advance of donating at your local clinic.
In order to prevent this, international health regulations require all blood products, such as organs or tissues, to be screened for a number of viral or bacterial contaminations before they are used.
During the screening process any blood products which contain HIV, hepatitis B, hepatitis C, or syphilis will be disposed of.
This means that the transmission of HIV through blood products is very rare, but examples have occurred in some low-income countries which lack the equipment to test all blood.
What Conditions Are Considered To Be Opportunistic
Some of the most common of these OIs/cancers among HIV-positive people include:
Cancer: The types of cancers that are you are more likely to get if you have AIDs include lymphoma, Kaposis sarcoma, invasive cervical cancer, anal cancer, liver cancer, and cancers of the mouth, throat and lungs.
Candidiasis : This condition is caused by Candida fungus. It can happen in the skin, nails and mucous membranes throughout the body, such as the mouth or the vagina. The cases can be troublesome, but thrush is especially dangerous when it affects the esophagus or parts of the respiratory system .
Pneumonia: This respiratory condition is most commonly caused by _Pneumocystis jirovecii and the bacterium Streptococcus pneumoniae._
Salmonella: This infection is spread through contaminated food and water. It causes diarrhea, vomiting and nausea.
Toxoplasmosis: This disease is caused by a parasites that live in cats and rodents and other warm-blooded animals. The infection is spread through the feces. Toxoplasmosis can cause severe problems in the lungs, heart, brain and other organs. If you have a cat, wear gloves to change the litter and be thorough in washing your hands.

What You Can Do
Get tested for HIV. CDC recommends that everyone between the ages of 13 and 64 get tested for HIV at least once as part of routine health care. People with certain risk factors should get tested at least once a year.
If you were HIV-negative the last time you were tested and answer yes to any of the following questions, you should get an HIV test because these things inc rease your chances of getting HIV.
- Are you a man who has had sex with another man?
- Have you had sex —anal or vaginal— with a partner who has HIV?
- Have you had more than one sex partner since your last HIV test?
- Do you have another sexually transmitted disease ?
- Do you have hepatitis or tuberculosis ?
- Have you had sex with someone who could answer yes to any of these questions or someone whose sexual history you dont know?
You should be tested at least once a year if you answered yes to any of these questions. Sexually active gay and bisexual men may benefit from more frequent testing , depending on their risk.
If you think youve recently been exposed to HIV during sex or through sharing needles, syringes, or other injection equipment , talk to your health care provider or an emergency room doctor right away about taking post-exposure prophylaxis . You must start PEP within 72 hours of a possible exposure, but the sooner you start PEP, the better.
Also, anyone who has been sexually assaulted should get an HIV test as soon as possible after the assault.

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.
What Puts You At Risk For Stds And Hiv
You’re at risk if you:
- Have sex without using a condom, with someone who is infected.
- Have had an STD.
- Have more than one sex partner.
- Are under the influence of drugs and alcohol.
- Many women have STDs without having symptoms. This means that unless she gets tested, she may have an STD and not know it.
- Young women are getting HIV or an STD because the tissue lining the vagina is more fragile.
If you are a woman, take charge of your sexual health. Be sure to schedule pelvic exams and pap smears every year. Get tested and learn how to protect yourself from STDs and HIV.

Researching An Hiv Cure: The Main Approaches
Although the stem cell approach has had some success in the past, its very dangerous for the patient. It would only be considered a viable option, if the person needed a stem cell transplant to treat another more deadly condition, such as very advanced leukaemia which, unlike HIV, doesnt have as many other safe and effective treatment options available.
While there is promising research being carried out in these areas, there is no viable cure on the horizon.
Structure Of Health Provision
The provision of all health services in Uganda is shared between three groups: the government staffed and funded medical facilities private for profit or self-employed medics including midwives and traditional birth attendants and, NGO or philanthropic medical services. The international health funding and research community, such as the Global Fund for AIDS, TB and Malaria, or bilateral donors are very active in Uganda. Part of the success in managing HIV/AIDS in Uganda has been due to the cooperation between the government and the non-government service providers and these international bodies. Public Private Partnerships in Health are often mentioned in Europe and North America to fund construction or research. In Uganda, it is more practical being the recognition by the government and donor that a philanthropic health facility can receive free test kits for HIV screening, free mosquito nets and water purification to reduce opportunistic infections and free testing and treatment for basic infections of great danger to PLHA.

What Are Hiv And Aids
- HIV is a virus that attacks and weakens a person’s immune system. The immune system is made up of a network of cells, tissues, and organs that work together to protect the body and fight off germs and diseases.
- If the immune system of an HIV-positive person gets so weak that it can no longer fight off a range of health problems it would normally be able to cope with, the person is considered to have AIDS.
- HIV can be passed from person to person through blood, semen, vaginal fluids, breast milk and other body fluids. It can happen:
- When a person has sex with someone who has the HIV virus and they do not use a condom
- When people exchange infected needles or syringes
- During pregnancy, childbirth or breastfeeding, when an HIV-positive mom can pass the virus to her baby .
Symptoms Of Hiv/aids And Stages
Many people donât have symptoms at first, and sometimes even for years or decades. But there are signs that can happen, such as flu-like symptoms soon after you become infected with HIV. Even if you donât feel sick, HIV damages the immune system. It hijacks infection-fighting white blood cells called CD4 cells and uses them to churn out thousands of copies of itself. Without treatment, HIV destroys so many of these cells that your body canât protect you from life-threatening infections. If your CD4 count drops below 200, you have AIDS.
There are three stages of HIV infection:
Stage 1: This the earliest stage. You may also hear it called the âacuteâ stage. You might have a fever, rash, fatigue, chills, and other flu-like symptoms. But you might not have any symptoms. If you do, they may start 2-4 weeks after youâre infected. During this time, the virus quickly makes many copies of itself.
Stage 2: During this stage, HIV continues to reproduce, and it slowly damages your immune system over time. You might not feel sick or have symptoms. But HIV isnât gone, and you can still spread it to other people. This stage can last for years or even decades.
Stage 3: This is when you have AIDS. Your immune system has been severely damaged, leaving you vulnerable to other illnesses. With AIDS, many people have symptoms such as chills, fever, sweats, swollen lymph glands, weakness, and weight loss.

Is It Safe For Children With Hiv To Receive Routine Immunizations
MMR, or measles, mumps, and rubella vaccine, is safe to give to children with HIV, unless they have a severely weakened immune system.
DTaP/Td vaccine is safe to give to infants and children with HIV.
Hib and Hep B vaccines are safe to give to children with HIV.
Hepatitis A and B vaccines are safe to give to HIV-positive children.
VZIG should be considered for known HIV-positive children, depending on their immune status.
A yearly influenza vaccine is recommended for children with HIV, as well as any individual living in the same household as a child with HIV. There are two types of influenza vaccine children and adults with HIV should receive the “shot” form of the vaccine–not the nasal spray form, as it contains a live virus. Pneumococcal vaccine can be safely administered to age-appropriate HIV-infected children.
Always consult with your child’s doctor regarding immunizations for an HIV-infected child.
