									The symptoms of HIV and AIDS vary and depend on the stage of the
disease. The disease can be divided into three different categories.




AIDS and HIV - symptoms



Three categories
The symptoms of HIV and AIDS vary from patient to patient and depend
on the stage of the disease.in 1993, the Centers for disease control
and prevention (CDC) in the United States has defined three
categories of AIDS disease.

» Category A

Category A include acute symptomatic HIV infection and asymptomatic
HIV infection.

Acute symptomatic HIV infection:About half of those affected, six
days to six weeks after infection occurs flu-like complaints such as
fever, rash, swollen lymph nodes, headers and sore throat. Also, if
you have any complaints, can pass HIV to others. At this time, the
HIV test is still negative. Only one to three months after the
infection are detectable antibodies in their blood.

Asymptomatic HIV infection (latency period):Often followed by a
symptom-free period that is individually vary in length and can last
up to many years from a few months now. Nevertheless reproduces the
virus during which further and destroyed the immune cells.Tests
showed a distinct decrease of these immune cells in the blood.

» Category B

Category B HIV infection reflected this that infected people
increasingly suffering from health problems but are not directly
related to HIV infection.Rather, the immune system already heavily
attacked at this stage leads to following illnesses and symptoms:
     Chronic diarrhea
     Permanently increased body temperature
     Nervous disorders (neuropathy)
     Oral thrush
     Herpes infections
     Switch pads, caused by the Epstein-Barr virus

» Category C

The so-called AIDS defining diseases fall into this category of
infection with HIV.These include:

     Wasting syndrome: Involuntary loss of more than ten percent of
      body weight with persistent diarrhea and malaise.
     HIV-associated encephalopathy (HIVE):Infection of connective
      tissue with resulting destruction of the central nervous system.
      Opportunistic infections: AIDS by opportunistic infections -
      so diseases that can only occur because the immune system is
      weakened by HIV is reflected in most cases.These include
      infections caused by fungi, viruses, bacteria or single-celled
      organisms (Protozoa). Chronic lung infections and herpes
      infections are typical.
     Malicious changes (malignancies):These include the Kaposi
      syndrome as well as malicious changes of the central nervous
      system.

These diseases are a sign that the immune system by the HIV virus is
already severely damaged.

Next to the categories A, B and C on the symptoms doctors use the
laboratory categories 1, 2 and 3 to the Division of AIDS disease in
addition. This information reflects the number of T helper cells (CD4
lymphocytes) and provides information about the State of the immune
system.

AIDS-related opportunistic infections
» Bacterial infections

The infection with atypical Mycobacteria especially the Mycobacterium
Avium subspecies paratuberculosis, often occurs as a result of HIV
infection. Usually spreads these pathogens in the respiratory tract.
Advanced infection and a reduced number of CD4 lymphocyte sub 50 100),
the bacteria but can affect all institutions including bone
marrow.This leads to symptoms such as fever, weight loss, stomach
pains and diarrhoea.

Tuberculosis (TB) the most common disease associated with HIV
infection is worldwide.All HIV-positive people should make therefore
a tuberculosis skin test or an x-ray examination of the lungs.You are
infected with tuberculosis and the disease is not active, you should
have still treat.Tuberculosis is more dangerous than many other
opportunistic infections, because she can be transferred to HIV
infected (by coughing or sneezing).

Usually the virus attacks the lungs when HIV also many other. The
disease also occurs when people with a high mirror on CD4 lymphocytes
- and often even before other HIV associated diseases show.There is
also always TB bacteria that are resistant to common antibiotics
combination. Doctors speak Multidrug-resistant tuberculosis (MDR-TB).

» Viral infections

The HIV heaped common herpes virus, Cytomegalovirus (CMV) is usually
transmitted by bodily fluids like saliva, blood or semen.At least
half of the population has undergone an infection and carries the
virus in the body. The immune system is healthy, no symptoms arise.
Weak immune systems but attacks and damages the virus various organs.
The infection of the retina (CMV Retinits) because it leads to
blindness untreated, the infection of the brain by CMV is
particularly feared.

Hepatitis B and C are transferred in the same way as HIV. In a
simultaneous infection of hepatitis and HIV, HIV disease is faster
progressing. The HIV drugs may also charge the liver.

The herpes simplex virus (HSV) affects the skin in the face or in the
genital area. Normally Herpes infections sound off after some time,
but you might. People who are HIV positive, skin infestation is
severe and heal more slowly.Also systemic infections can occur which
affect all the institutions.This can cause life-threatening
infections in infants.

The JC virus causes the so-called progressive multifocal
Leukoencephalopathy (PML), a very serious infection of the brain. It
occurs often in HIV patients, when the immune system is already
extremely damaged. The symptoms are speech, half-page weakness,
blindness or sensory loss.
» Infections by fungi

Candida infections are common in HIV-positive people.This fungus
causes inflammation and a thick white coating on the mucous membrane
of mouth, tongue, esophagus, or vagina.Consequences are dysphagia and
burning behind the breastbone.Children can have severe symptoms, the
food and drink very difficult.

Kryptokokken meningitis (form of meningitis) also increasingly occurs
when HIV.It is caused by a fungus that is found in the Earth and is
the most common infection of the central nervous system in HIV
patients.Symptoms include headache, fever, neck stiffness and light
sensitivity.Kryptokokken meningitis can be treated successfully, but
the treatment must be carried out at an early stage.Emerging
infection patients must take a long time drugs, to prevent a new
disease.

» Infection by parasites

The so-called Pneumocystis carinii pneumonia (PCP), a form of
pneumonia, occurs very frequently in AIDS patients.Symptoms include
fever, cough, shortness of breath.PCP is the leading cause of death
in children with HIV.New antiretroviral drugs can to strengthen the
immune system of many interested parties of heavy PCP diseases are
decreasing.

Toxoplasmosis is the most common cause of brain damage in HIV
patients.Toxoplasma gondii is a parasite that is spread by cats.In
healthy people, infection rarely leads to symptoms.In patients with
AIDS but it throws a brain inflammation (encephalitis).Typical
symptoms are disorientation, seizures, voice and movement disorders.

Cryptosporidiosis infection occurs by parasites that normally live in
the intestines of animals.The infection through contaminated water or
contaminated food.The parasite multiplies in the intestine and bile
ducts and causes severe, chronic diarrhea.

Cancer
Kaposi's Sarcoma, a tumor of the blood vessel wall is the most common
cancer among HIV-positive people – especially in men.This form of
cancer, however, is extremely rare in non-infected individuals.The
disease usually begins with red or purple spots on the skin or in the
mouth.Kaposi-Sarkome can attack but also internal organs such as the
gastrointestinal tract and the lungs.Small lesions can be treated
with liquid nitrogen, radiation or local chemotherapy.The tumor has
spread a systemic chemotherapy must follow.

Non-Hodgkin's lymphoma, arising lymphocytes, a special subset of
white blood cells.Usually starts the cancer in the lymph nodes and
spread from there to other organs.Early symptoms are painless
swelling of the lymph nodes of the neck or under the arms.
