What is the difference between HIV and AIDS?
Signs and symptoms of early HIV infection:
For the most part, the symptoms of HIV are the result of infections caused by bacteria, viruses, fungi and parasites. These conditions do not normally develop in individuals with healthy immune systems, which protect the body against infection.Many people with HIV have no symptoms for several years. Others may develop symptoms similar to flu, usually two to six weeks after catching the virus. The symptoms can last up to four weeks.
Symptoms of early HIV infection may include:
►Sweats (particularly at night)
►A red rash
Asymptomatic HIV infection:
In many cases, after the initial symptoms disappear, there will not be any further symptoms for many years. During this time, the virus carries on developing and damages the immune system. This process can take up to 10 years. The infected person will experience no symptoms, feel well and appear healthy.
Late-stage HIV infection:
If left untreated, HIV weakens the ability to fight infection. The person becomes vulnerable to serious illnesses. This stage of infection is known as AIDS.
Signs and symptoms of late-stage HIV infection may include:
►Diarrhea, which is usually persistent or chronic
►Fever of above 37C (100F) lasting for weeks
►Shortness of breath
►Swollen glands lasting for weeks
►White spots on the tongue or mouth
During late-stage HIV infection, the risk of developing a life-threatening illness is much greater. Examples include:
►Esophagitis (an inflammation of the lining of the lower end of the esophagus)
►Infections to the nervous system (acute aseptic meningitis, subacute encephalitis, peripheral neuropathy)
►Some cancers, such as Kaposi's sarcoma, invasive cervical cancer, lung cancer, rectal carcinomas, hepatocellular carcinomas, head and neck cancers, cancers of the immune system known as lymphomas
►Toxoplasmosis (a disease caused by a parasite that infects the brain. It can also cause disease in the eyes and lungs)
Life-threatening illnesses may be controlled and treated with proper HIV treatment.
What causes HIV/AIDS?
HIV is a retrovirus that infects the vital organs of the human immune system. The disease progresses in the absence of antiretroviral therapy. The rate of disease progression varies widely between individuals and depends on many factors (age of the patient, body's ability to defend against HIV, access to health care, existence of coexisting infections, the infected person's genetic inheritance, resistance to certain strains of HIV).
HIV can be transmitted through:
►Sexual transmission: It can happen when there is contact with infected sexual secretions (rectal, genital or oral mucous membranes). This can happen while having unprotected sex, including vaginal, oral and anal sex or sharing sex toys with someone infected with HIV.
►Perinatal transmission: The mother can pass the infection on to her child during childbirth, pregnancy, and also through breastfeeding.
►Blood transmission: The risk of transmitting HIV through blood transfusion is nowadays extremely low in developed countries, thanks to meticulous screening and precautions. Among drug users, sharing and reusing syringes contaminated with HIV-infected blood is extremely hazardous.
How is HIV/AIDS diagnosed?
Earlier HIV antiretroviral treatment is crucial it improves quality of life, extends life expectancy and reduces the risk of transmission.When an HIV-positive adult's CD4 cell count is 500 cells/mm3 or lower they should start treatment immediately.Currently, there is no vaccine or cure for HIV/AIDS. But treatments have evolved which are much more efficacious - they can improve patients' general health and quality of life considerably.
Emergency HIV pills: If an individual believes they have been exposed to the virus within the last 72 hours (three days), anti-HIV medication, called PEP (post-exposure prophylaxis) may stop infection. The treatment should be taken as soon as possible after contact with the virus.PEP is a very demanding treatment lasting four weeks. It is also associated with unpleasant side effects (diarrhea, malaise, nausea, weakness and fatigue).After a positive HIV diagnosis, regular blood tests are necessary to monitor the progress of the virus before starting treatment. The therapy is designed to reduce the level of HIV in the blood.
Antiretroviral drugs: HIV is treated with antiretrovirals (ARVs). The treatment fights the HIV infection and slows down the spread of the virus in the body. Generally, patients take a combination of medications called HAART (highly active antiretroviral therapy).The combination of drugs is adapted to each individual. HIV treatment is usually permanent and lifelong. HIV treatment is based on routine dosage. Pills must be taken on a regular schedule, every time. Common side effects include nausea, fatigue, diarrhea, skin rashes, moodiness, alterations to the adipose (fat) tissue, birth defects.
HIV/AIDS and diarrhea: HIV-positive patients, and those with AIDS tend to suffer from diarrhea. It is the main reason people go off their medications, or switch to other antiretroviral therapies prematurely.
Antifungal cream Ciclopirox eradicates HIV - researchers at the Rutgers New Jersey Medical School reported in the journal PLoS ONE that Ciclopirox, a widely used antifungal cream, as well as Deferiprone, a medication used to remove excess iron from the body, eradicate HIV in cultured cells. They added that when treatment stops, the virus does not return.
Complementary or alternative medicine: Although widely used, alternative/complementary medications, such has herbal ones, have not been proven to be effective or ineffective. According to some limited studies, mineral or vitamin supplements may provide some benefits. Patients are urged to discuss these options with their doctors.
