In the first few weeks after initial infection, individuals may experience no symptoms or an influenza-like illness including fever, headache, rash, or sore throat. As the infection progressively weakens the immune system, an individual can develop other signs and symptoms, such as swollen lymph nodes, weight loss, fever, diarrhoea and cough.
Without treatment, they could also develop severe illnesses such as tuberculosis, cryptococcal meningitis, severe bacterial infections and cancers such as lymphomas and Kaposi's sarcoma, among others. HIV can be transmitted via the exchange of a variety of body fluids from infected individuals, such as blood, breast milk, semen and vaginal secretions.
Individuals cannot become infected through ordinary day-to-day contact such as kissing, hugging, shaking hands, or sharing personal objects, food or water. HIV infection can be detected with great accuracy, using WHO prequalified tests within a validated approach. It is important that these tests be used in combination and in a specific order that has been validated and is based on HIV prevalence of the population being tested.
Serological tests, such as rapid diagnostic tests RDTs or enzyme immunoassays EIAs , detect antibodies produced by an individual as part of their immune system to fight off foreign pathogens, rather than direct detection of HIV itself. This early period of infection represents the time of greatest infectivity; however, HIV transmission can occur during all stages of the infection.
Notably, once a person diagnosed with HIV has started treatment, they should not be retested. For infants and children less than 18 months of age, serological testing is not sufficient to identify HIV infection: virologic testing must be provided at 6 weeks of age, or at birth to detect the presence of the virus in infants born to mothers living with HIV. HIV testing should be voluntary — a person has the right to refuse to be tested.
Mandatory or coerced testing by a health care provider, authority, or by a partner or family member is not acceptable as it undermines good public health practice and infringes on human rights. Countries are looking for ways to rapidly increase uptake of HIV testing services, especially for populations with low access and those at higher risk that would otherwise not get tested.
One approach is HIV self-testing, where a person collects his or her own specimen oral fluid or blood and then performs an HIV test and interprets the result, often in a private setting, either alone or with someone he or she trusts. HIV self-testing does not provide a definitive HIV-positive diagnosis: instead, it is an initial test which requires further testing by a health worker.
The sexual partners and drug injecting partners of people diagnosed with HIV infection have an increased probability of also being HIV-positive. WHO recommends assisted HIV partner notification services as a simple and effective way of reaching these partners, many of whom are undiagnosed and unaware of their HIV exposure, and may welcome support and an opportunity to test for HIV. Individuals can reduce the risk of HIV infection by limiting exposure to risk factors.
Key approaches for HIV prevention, which are often used in combination, are listed below. Correct and consistent use of male and female condoms during vaginal or anal penetration can protect against the spread of sexually transmitted infections, including HIV.
Through testing, people learn of their own infection status and access necessary prevention and treatment services without delay. WHO also recommends offering testing for partners or couples. Additionally, WHO is recommending assisted partner notification approaches so that people with HIV receive support to inform their partners either on their own, or with the help of health care providers.
The infectiousness of HIV varies with the concentration of the virus in the blood — the more virus there is, the more likely it will get into genital fluids and be passed on during sex.
But then the immune system produces antibodies that attack HIV. Some estimates suggest that a person who has been recently infected with HIV may be as much as times more likely to transmit the virus to a partner than someone who has been infected for a long time.
If one member of a Ugandan sexual network becomes HIV-positive, the virus will spread very quickly to all other members of the network in a very short time.
One morning not long ago, I accompanied an HIV-prevention worker in Botswana named Willington Mongwa as he made his rounds in Old Naledi, a relatively poor neighborhood in the capital, Gaborone.
We passed a bar in which about 15 people, most of them men, sat on tree stumps drinking beer made from distilled sorghum. I asked Willington if we could ask the drinkers some questions. We approached a group of three young men, and they offered us some of their beer and gratefully accepted the condoms we offered them.
He had been seeing all three for at least two years. He used condoms with the secret girlfriends but not with the real one. How many secret boyfriends do those secret girlfriends have?
I asked. And the real girlfriend? Several other men I met had similar sexual arrangements. Botswana is a culture of migrants, where both men and women often spend time away from their homes and may have long-term relationships with different people in different places.
The traditional form of wealth is cattle, which are kept on remote cattle posts. For centuries boys tended the cattle, and men visited the herds from time to time, leaving their wives behind. Even though Botswana is a relatively wealthy country by African standards, some 38 percent of the population is classified as poor.
The government provides rations to the destitute, but many people told me they had experienced deprivation and unemployment. Women in Botswana generally work at low-wage jobs such as housecleaning, child care, or farming. As a result, girls and women are drawn into relationships with relatively wealthy men who help them and their families.
These men may have several long-term female sexual partners at the same time — one or two in their home villages and one or two in town. Girls are particularly vulnerable. Roughly equal numbers of men and women in Botswana are HIV-positive, but the HIV rate is much higher among teenage girls than among teenage boys, although boys and girls become sexually active at roughly the same age.
A study in found that 20 percent of girls in one region of Botswana had been asked by their teachers to have sex; half said they accepted, fearing lower grades if they said no.
Unlike many African countries, where government AIDS programs have been desultory, the Botswanan government is at war against the virus. Free condoms are available in remote clinics, bars, and shops. The government has also funded a Danish-run program that employs field-workers to bring the message of HIV prevention to every household.
Despite these efforts, the HIV epidemic in Botswana shows few signs of abating. Studies show that even when used consistently, condoms fail to prevent infection 10 percent of the time, due to breakage and human error. Treatment uptake was slow at first as there was a major shortage of health workers and even these few cases overwhelmed the health system. Although access to treatment in sub-Saharan Africa greatly expanded in the first decade of the 21st century, a change in WHO guidelines in led to an increased number of people estimated to be in need of treatment.
However, the difficulties that South Africa will face in turning back the tide on its AIDS epidemic were made clear by the lower than expected number of tests carried out in the first months of the campaign, prolonged public sector strikes involving health workers, and ARV drug stockouts.
In a decade in which ethical issues were rising up the corporate agenda, a number of large companies also began to provide AIDS treatment programmes for their employees. The vice-president of Anglo American, a large South African mining firm explained that the cost for the firm was justified as the dramatically reduced absenteeism compensated for three-quarters of the cost of the treatment programme.
This was believed to be partly due to increased condom use since the early s, as well as young people delaying first sex and reducing the number of casual sex partners. This trend may have accounted for the reported decline in HIV prevalence in some parts of Africa, notably Kenya, Zimbabwe and urban areas of Burkina Faso. However, the decline was also likely to be a result of high-mortality rates. In , it was revealed that HIV infections had reduced by more than a quarter between and in 22 countries in Africa, including among young people and women.
Elsewhere in southern Africa HIV prevalence levels appeared to have levelled off by i. This trend continued as the end of the first decade came to a close. It was estimated in that since the beginning of the epidemic more than 15 million Africans had died from AIDS , equivalent to the combined populations of London and New York.
In this context it becomes possible to understand the massive impact that the AIDS epidemic has had on families, communities, workplaces and national and regional development in Africa.
Rapid increases in bilateral donations especially from the U. However, the financial crisis present started to have a noticeable effect on the provision of funding. In , global funding remained flat; a marked change from the substantial increase. A report in also noted how funding commitments were having an impact on work on the ground in eight countries in Africa, stalling the scale up of treatment, prevention and care services and increasing the frequency of drug stock outs.
Not only will the effects of the current epidemic be felt for generations to come, but the lack of a cure for AIDS coupled with limited access to treatment in Africa means that the worst is still not over and millions of people will continue to suffer the multiple impacts of the AIDS epidemic. But at this point we are numb. My name is cambell Spivey i will like us to share tips on how to identify a real spell caster cos alot of people have fallen victim of scam as i have come across lots of comments lately i was a victim too and from experience and what i know i decide to open this thread, only fake spell casters ask for the followings: COURIER CHARGES: no matter where you are in the world, no matter the distance and continent a real spell caster will cast a spell effectively without you seeing it or the spell caster getting it to you to use it so long as he has the names or pix..
STRAIGHT: no excuses for failure, if money was needed in the first place for courier he should have say so, so one can know how prepared he is.. Am Cured and happy now for about a month.. I do not think you have all the facts, tell the truth how H. I am certain you know the truth, share the truth then we can talk. Very interesting.
I just wonder how something as dramatic as AIDS went unnoticed for so long in Africa since it originated there. How is that possible when it originated there? This is the biggest question mark for me. Business as usual is not bringing down new infections or getting patients onto treatment. The government should go beyond strategies and push through barriers to actual implementation, get services into school, and re-educate South Africans about HIV.
That includes listening to young people and communities, making sure services are available away from clinics in communities and schools, supporting provinces in service provision, and elevating prevention and treatment for young people.
Turning the tide on the epidemic will require more than increasing the number of people on treatment; PEPFAR can provide unique support to South Africa to implement a multipronged strategy for young people as an urgent priority.
