Primary sign of HIV
HIV infection is the beginning of
AIDS. There can be no symptom shown when initially infected with HIV
virus. The time from initial HIV infection to the development of AIDS can
differ from person to person. Some maybe develop symptoms within weeks while some
may remain symptomless for years. Although the person infected with HIV virus
can remain without symptoms but they can still transmit the infection to others
during this “symptom free period”.
Most of
the people infected with HIV virus will develop into AIDS if not
treated. There are certainly a small amount of people who will develop AIDS
gradually or none at all. They are called the “nonprogressor” who seem to be
genetically different that prevents the HIV virus from harming the immune
system significantly.
The symptom of aids are the main result
of infections that do not normally develop in people with healthy immune
system. These are called the opportunistic infections.
Due
to the deteriorating immune system caused by the aids, symptoms shown are not
really the actual warning sign for aids. When the HIV invaded the body, it will
begin to destroy the CD4+ T cells which
are the immune system key infection fighters. Common symptoms are:
·
Chills
·
Fever
·
Headache
·
Sweats (particularly at night)
·
Swollen lymph glands in the armpits, groin or neck
·
Weakness
·
Weight loss
·
Diarrhea (may last to a week or more)
·
Vision unclear
·
Memory loss, depression and neurological disorders
*Note: At first,
infection with HIV may produce no symptoms. Some people, however, do experience
flu-like symptoms with fever, rash, sore throat, and swollen lymph nodes,
usually 2 - 4 weeks after contracting the virus. Some people with HIV infection
stay symptom-free for years between the time when they are exposed to the virus
and when they develop AIDS.
Although the
symptoms of primary HIV infection may be mild enough to go unnoticed, the
amount of virus in the blood stream (viral load) is particularly high at this
time. As a result, HIV infection spreads more efficiently during primary
infection than during the next stage of infection.
Clinical latent
infection
Persistent swelling of lymph nodes occurs during clinical latent HIV will happen in some people. There are no specific signs and symptoms if not for clinical latent HIV. The HIV virus will remain in the body free to infect white blood cells.
Persistent swelling of lymph nodes occurs during clinical latent HIV will happen in some people. There are no specific signs and symptoms if not for clinical latent HIV. The HIV virus will remain in the body free to infect white blood cells.
This clinical
latent infection will typically lasts 8 to 10 years. Some people stay in this
stage for a longer period but others would progress to a more severe disease
much sooner.
The later sign of HIV
·
rapid weight loss
·
dry cough
·
recurring fever or profuse night sweats
·
profound and unexplained fatigue
·
swollen lymph glands in the armpits, groin, or neck
·
diarrhea lasting more than a week
·
white spots or unusual blemishes on the tongue, in
the mouth,
or in the throat
·
pneumonia
·
red, brown, pink, or purplish blotches on or under
the skin or
inside the mouth, nose, or eyelids
·
memory loss, depression, and other neurological
disorders
HIV destroys the white blood cells. These white blood cells
are required to fight infection. As the white blood cells count drop to a dangerous
level, numerous diseases and infection will emerge. At this point, a person is
said to have AIDS (Acquired Immune Deficiency Syndrome).
According to CDC, as with the initial of HIV infection, sign
and symptoms shown cannot be rely to establish a diagnosis of AIDS. The symptoms
of AIDS are similar to the symptoms of many other illnesses. AIDS is a medical
diagnose made by a healthcare profession based on specific criteria established
by the CDC.
AIDS Symptom
In the past, having AIDS was defined as having HIV
infection and getting one of these other diseases. Today, according to the
Centers for Disease Control and Prevention, a person may also be diagnosed with
AIDS if they are HIV-positive and have a CD4 cell count below 200 cells/mm3,
even if they don't have an opportunistic infection.
AIDS can also be diagnosed if an individual
develops one of the opportunistic infection and cancer that usually occur in
HIV infected person. For individuals with healthy immune system, such
infections are unusual. The immune system must be severely damaged for a person
with HIV to be diagnosed with AIDS.
Below is a list of AIDS-related infections and cancers that people with AIDS may get when their CD4 count decreases.
The following illnesses are common with a CD4 count
below 350 cells/mm3:
- Herpes simplex virus -- causes ulcers/small blisters in the mouth or genitals,
happens more often and usually much more severely in an HIV-infected
person than in someone without HIV infection
- Herpes zoster (shingles)
-- ulcers/small blisters over a patch of skin, caused by reactivation of
the varicella zoster virus, the same virus that causes chickenpox
- Kaposi's sarcoma -- cancer of the skin, lungs, and bowel due to a herpes virus
(HHV-8). It can happen at any CD4 count, but is more likely to happen at
lower CD4 counts, and is more common in men than in women.
- Non-Hodgkin's lymphoma -- cancer of the lymph nodes
- Oral or vaginal thrush --
yeast (typically Candida albicans) infection of the mouth or
vagina
- Tuberculosis -- infection by
tuberculosis bacteria mostly affects the lungs, but can also affect other
organs such as the bowel, lining of the heart or lungs, brain, or lining
of the central nervous system (brain and spinal cord)
Common with CD4 count below 200 cells/mm3:
- Bacillary angiomatosis --
skin sores caused by a bacteria called Bartonella, which
may be caused by cat scratches
- Candida esophagitis --
painful yeast infection of the esophagus
- Pneumocystis jiroveci pneumonia, "PCP pneumonia," previously
called Pneumocystis carinii pneumonia, caused by a fungus
Common with CD4 count below 100 cells/mm3:
- AIDS dementia -- worsening
and slowing of mental function, caused by HIV
- Cryptococcal meningitis -- fungal infection of the lining of the brain
- Cryptosporidium diarrhea --
Extreme diarrhea caused by a parasite that affects the gastrointestinal
tract
- Progressive multifocal leukoencephalopathy -- a disease of the brain caused by a
virus (called the JC virus) that results in a severe decline in mental and
physical functions
- Toxoplasma encephalitis --
infection of the brain by a parasite, called Toxoplasma gondii,
which is often found in cat feces; causes lesions (sores) in the brain
- Wasting syndrome -- extreme
weight loss and loss of appetite, caused by HIV itself
Common with CD4 count below 50/mm3:
- Cytomegalovirus infection -- a viral infection that can affect almost any
organ system, especially the large bowel and the eyes
- Mycobacterium avium -- a
blood infection by a bacterium related to tuberculosis
In addition to the CD4 count, a test called HIV RNA
level (or viral load) may be used to monitor patients. Basic screening lab
tests and regular cervical Pap smears are important to monitor in HIV
infection, due to the increased risk of cervical cancer in women with a
compromised immune system. Anal Pap smears to detect potential cancers may also
be important in both HIV-infected men and women.
