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.

Fever in Adults and Children
Although a fever technically is any body temperature above the normal of 98.6 F (37 C), in practice, a person is usually not considered to have a significant fever until the temperature is above 100.4 F (38 C). Fever is part of the body's own disease-fighting arsenal; rising body temperatures apparently are capable of killing off many disease-producing organisms.

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.
Cancer Risk Factors
Though it's difficult to say why some people develop cancer while others don't, research shows that certain risk factors increase a person's odds of developing cancer. These risk factors include growing older, family history of cancer, diet, alcohol and tobacco use, and exposure to sunlight, ionizing radiation, certain chemicals, and some viruses and bacteria.
Cervical Cancer (Cancer of the Cervix)
Cervical cancer is cancer of the entrance to the womb (uterus) caused by the human papillomavirus (HPV). Regular pelvic exams, Pap testing and screening can detect precancerous changes in the cervix. Cervical cancer can be prevented by a vaccine. The most common signs and symptoms are an increase in vaginal discharge, painful sex, and postmenopausal bleeding. The prognosis and survival rate depends upon the stage at which the cancer was diagnosed.
Circumcision Pros and Cons
The list of medical pros and cons regarding circumcision is long. Though the American Academy of Pediatrics has repeatedly stated that "there is no absolute medical indication for routine circumcision of the newborn," it has been shown that uncircumcised men have a higher incidence of urinary tract infections, sexually transmitted diseases, and penile cancer than circumcised men.
Circumcision Procedure
Circumcision is a surgical procedure that removes the foreskin of the penis. Circumcision is generally a safe surgical procedure.
Clinical Trials

Clinical research is a type of study of clinical or biomedical questions through the use of human subjects. Clinical trials are divided into five types:- Treatment trials
- Prevention trials
- Diagnostic trials
- Screening trials
- Quality of life trials
