HIV (human immunodeficiency virus) infection left untreated causes AIDS (acquired immunodeficiency syndrome). Still incurable, AIDS describes immune system collapse that opens the way for opportunistic infections and cancers to kill the patient. Early symptoms and signs of HIV infection include flu-like symptoms and fungal infections, but some people may not show any symptoms for years.
Highly active antiretroviral therapy (ART) is the standard treatment for HIV infection. These combination drug regimens have made HIV much less deadly, but a cure or vaccine for the pandemic remains out of reach.
HIV is usually transmitted through sexual contact or sharing IV drug needles, but can also infect someone through contact with infected blood.
Sexual abstinence, safe sex practices, quitting IV drugs (or at least using clean needles), and proper safety equipment by clinicians and first responders can drastically reduce transmission rates for HIV/AIDS.

Read about the health risks of chronic heavy or binge drinking. Anemia, cancer, gout, cardiovascular disease and many more disease can be caused from heavy or binge drinking.
Anemia
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased. There are several types of anemia such as iron deficiency anemia (the most common type), sickle cell anemia, vitamin B12 anemia, pernicious anemia, and aplastic anemia. Symptoms of anemia may include fatigue, malaise, hair loss, palpitations, menstruation, and medications. Treatment for anemia includes treating the underlying cause for the condition. Iron supplements, vitamin B12 injections, and certain medications may also be necessary.
Blood Transfusion
During a blood transfusion, blood or blood products are transferred from one person to another. There are two types of transfusions, autologous (your own blood), and donor blood (someone else's blood). There are four blood types: A; B; C; and O.In addition, each person's blood is either Rh-positive or Rh-negative. It is important to know what to expect before, during, and after a blood transfusion, and the risks, side effecs, or complications of blood transfusions.
Breastfeeding (and Formula Feeding)
It's important to know whether you will breastfeed or bottle-feed your baby prior to delivery, as the breasts' ability to produce milk diminishes soon after childbirth without the stimulation of breastfeeding. Breast milk is easily digested by babies and contains infection-fighting antibodies and cholesterol, which promotes brain growth. Formula-fed babies actually need to eat somewhat less often since formula is less readily digested by the baby than human milk. This article explores the advantages and disadvantages of both forms of feeding.

What is dementia? Learn about dementia disorders such as Lewy Body Dementia, Alzheimer's disease (AD), Vascular (multi-infarct) dementia (MID), and more. Discover dementia stages, signs of dementia, causes, diagnosis, treatments, and medications.
ELISA Tests
ELISA stands for "enzyme-linked immunosorbent assay." This is a rapid immunochemical test that involves an enzyme (a protein that catalyzes a biochemical reaction). It also involves an antibody or antigen (immunologic molecules).
Headache
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.

HIV Testing
HIV antibody tests detect antibodies the body produces to neutralize the virus. HIV RNA testing uses polymerase chain reaction to detect HIV RNA in a person's blood. It usually takes one to three days to get results.

Pneumococcal Vaccination (Pneumonia Vaccine)
Pneumococcal vaccination prevents one of the most common and severe forms of pneumonia. It is usually given only once in a lifetime, usually after the age of 55, to someone with ongoing lung problems (such as chronic obstructive pulmonary disease (COPD) or asthma) or other chronic diseases (including those involving the heart and kidneys).

The word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.

Swollen Lymph Nodes (Glands)
Lymph nodes help the body's immune system fight infections. Causes of swollen lymph nodes (glands) may include infection (viral, bacterial, fungal, parasites). Symptoms of swollen lymph nodes vary greatly, but may include fever, night sweats, toothache, sore throat, or weight loss. Causes of swollen lymph nodes also vary, but may include cancer, the common cold, mono, chickenox, HIV, and herpes. The treatment of swollen lymph nodes depends upon the cause.
Thrush (Oral Candidiasis)
Thrush is an infection of the mouth caused by the Candida fungus. Symptoms of thrush include pain or difficulty swallowing, a feeling that food gets stuck in the throat, and fever.
