Infectious Diseases

Infectious diseases are all caused by infective agents such as bacteria, viruses, fungi or parasites. Some infectious diseases can be passed from person to person. Some, however, are transmitted via bites from insects or animals. Others are acquired by ingesting contaminated food or water or other exposures in the environment.

Dementia Due to HIV Infection
Decline in mental processes is a common complication of HIV infection (and many other conditions). Although the specific symptoms vary from person to person, they may be part of a single disorder known as AIDS dementia complex, or ADC. Other names for ADC are HIV-associated dementia and HIV/AIDS encephalopathy. Common symptoms include decline in thinking, or cognitive, functions such as memory, reasoning, judgment, concentration, and problem solving. Other common symptoms are changes in personality and behavior, speech problems, and motor (movement) problems such as clumsiness and poor balance. When these symptoms are severe enough to interfere with everyday activity, a diagnosis of dementia may be warranted. AIDS dementia complex typically occurs as CD4+ count falls to less than 200 cells/microliter. It may be the first sign of AIDS. With the advent of highly active antiretroviral therapy (HAART), the frequency of ADC has declined from 30-60% of people infected with HIV to less than 20%. HAART may not only prevent or delay the onset of AIDS dementia complex in people with HIV infection, it can also improve mental function in people who already have ADC.

Human Immunodeficiency Virus Primary Infection
Primary HIV infection (PHI) syndrome is an acute, flu-like illness that develops anywhere from 1&#8211,6 weeks following exposure to HIV (the human immunodeficiency virus). Chronic infection with this virus can cause AIDS (acquired immune deficiency syndrome). The HIV virus destroys the body's ability to fight infections and some cancers by progressively attacking and damaging the cells of the immune system. The most common way of becoming infected is through unprotected sex with an infected partner.

HIV: Opportunistic Infections
Opportunistic infections are infections that occur if you have a weakened immune system. Your immune system, when healthy, protects you from infections. People with human immunodeficiency virus (HIV) have weakened immune systems that are unable to fight certain infections.People with weakened immune systems can even get infections from organisms that don't usually cause diseases in health people.HIV attacks specific cells in your immune system known as helper T cells. These white blood cells, also known as CD4 (or CD4+) cells, help to keep infection at bay.Having HIV reduces the numbers of these helpful cells in your body, and makes it harder for your immune system to fight off disease.

Opportunistic Infections in AIDS
Having AIDS weakens your body's immune system. Your immune system normally fights germs that enter your body. When AIDS makes it weak, it can't fight germs well. This can lead to serious infections that don't often affect healthy people. These are called opportunistic infections (OIs). There are many types of OIs. Tuberculosis and a serious related disease, mycobacterium avium complex (MAC) are bacterial infections. Viral infections include cytomegalovirus (CMV) and hepatitis C. Fungi cause thrush (candidiasis), cryptococcal meningitis, pneumocystis carinii pneumonia (PCP) and histoplasmosis, and parasites cause crypto (cryptosporidiosis) and toxo (toxoplasmosis).

Understanding Vaginal Yeast Infection Medications
Yeast infections are overgrowths of normally growing fungi in the vagina. Overgrowth inflames the vagina and creates discharge, odor, irritation, and/or itching. Normally growing bacteria in the body typically keep yeast fungi in check. If the natural balance of microorganisms is upset, the yeast may grow out of control. This is so common that 75% of all women experience a yeast infection at some time in their lives. Disruption of this natural balance may occur with any of the following: Use of antibiotics Diabetes A weakened immune system (for example from HIV/AIDS, steroid use, pregnancy, cancer chemotherapy or other drugs that weaken the immune system) Use of douches or feminine hygiene sprays Tight or noncotton underwear Hormonal changes Ovulation Menopause Pregnancy Use of birth control pills Use of hormone therapy

Nail Infection, Fungal
Onychomycosis, commonly known as a fungal nail infection, is infection of the fingernails or toenails by forms of fungi and yeast. Fungal nail infections account for nearly one-half of all nail disorders. In the most common form of fungal nail infections, fungus grows under the growing portion of the nail and spreads up the finger (proximally) along the nail bed and the grooves on the sides of the nails. A less common type of fungal nail infection may occur in those with HIV/AIDS.
