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.

Balanitis (Inflammation of the Head of the Penis)
Balanitis is a condition in which the skin of the head of the penis becomes inflamed. If the foreskin is also inflamed, it is referred to as balanoposthitis. Balanitis usually occurs in uncircumcised males with symptoms of pain, swelling, and redness at the head of the penis. Often, balanitis is caused by poor hygiene or some medical conditions such as diabetes, and yeast infections. Treatment for balanitis is directed at the cause of the condition and may include creams or other medications.Balanitis is not an STD; however, it may have similar symptoms.
Necrotizing fasciitis is also known as a flesh-eating bacterial infection, Fournier's gangrene, suppurative fasciitis, and necrotizing cellulitis. The disease is occasionally caused by fungi, but most cases are caused by bacteria that enter the skin through insect bites, cuts, puncture wounds, or surgical incisions. Signs and symptoms include pain, redness, swelling, fever, chills, skin ulceration, bullae formation, black scabs, gas formation, and fluid draining from the site of infection. Treatment involves hospitalization, the use of intravenous antibiotics, and debridement of the necrotic tissue.

AIDS (Acquired Immunodeficiency Syndrome)
AIDS is the advanced stage of HIV infection. Symptoms and signs of AIDS include pneumonia due to Pneumocystis jiroveci, tuberculosis, toxoplasmosis, seizures, weakness, meningitis, yeast infection of the esophagus, and Kaposi's sarcoma. Anti-retroviral therapy (HAART) is used in the treatment of AIDS.
Erythema nodosum is a skin inflammation that results in reddish, painful, tender lumps most commonly located in the front of the legs below the knees. Erythema nodosum can resolve on its own in three to six weeks, leaving a bruised area. Treatments include anti-inflammatory medications and cortisone by mouth or injection.
Human Immunodeficiency Virus (HIV)
HIV (human immunodeficiency virus) infection left untreated causes AIDS (acquired immunodeficiency syndrome). The human immunodeficiency virus (HIV) is a type of virus called a retrovirus, which can infect humans when it comes in contact with tissues that line the vagina, anal area, mouth, or eyes, or through a break in the skin. HIV infection is generally a slowly progressive disease in which the virus is present throughout the body at all stages of the disease. Three stages of HIV infection have been described. The initial stage of infection (primary infection), which occurs within weeks of acquiring the virus, often is characterized by the flu- or mono-like illness that generally resolves within weeks. The stage of chronic asymptomatic infection (meaning a long duration of infection without symptoms) lasts an average of eight to 10 years without treatment. The stage of symptomatic infection, in which the body's immune (or defense) system has been suppressed and complications have developed, is called the acquired immunodeficiency syndrome (AIDS). The symptoms are caused by the complications of AIDS, which include one or more unusual infections or cancers, severe loss of weight, and intellectual deterioration (called dementia). When HIV grows (that is, by reproducing itself), it acquires the ability to change (mutate) its own structure. These mutations enable the virus to become resistant to previously effective drug therapy. The goals of drug therapy are to prevent damage to the immune system by the HIV virus and to halt or delay the progress of the infection to symptomatic disease. Therapy for HIV includes combinations of drugs that decrease the growth of the virus to such an extent that the treatment prevents or markedly delays the development of viral resistance to the drugs. The best combination of drugs for HIV are those that effectively suppress viral replication in the blood and also are well tolerated and simple to take so that people can take the medications consistently without missing doses.
