Transcript of Communicable Diseases: HIV and AIDS

A person infected with HIV can progress to AIDS and is proven to have AIDS when only about or less than 200 of their CD4+ T cells are alive in a microliter of blood
People are also considered to have AIDS when they have infections from various types of organisms like fungi, virus, and bacteria
AIDS can cause multiple cancers like cervical cancer, Kaposi sarcoma, and lymphomas
Kaposi sarcoma is where round, reddish-brownish spots are found in the mouth and skin
The average survival time is 2-3 years As seen here, many of the symptoms of HIV seem like smaller and not as serious as it really is
People infected with HIV sometimes do not find these symptoms for 10 years or more
You can't really tell if you have HIV or not unless a doctor is consulted for an HIV test
Do not assume that you have HIV is you have one or more symptoms listed before since those are very common illnesses people experience photo credit Nasa / Goddard Space Flight Center / Reto Stöckli HIV and AIDS Communicable Diseases What is HIV and AIDS? What are the Symptoms for
HIV and AIDS? How does it Spread? HIV/AIDS Statistics What are the Treatments? What can You Do to
Prevent it? HIV The End
Works Cited HIV is an abbreviation for human immuno-deficiency syndrome
This is actually a type of virus that when contracted, can lead to AIDS
There are two types of HIV: HIV-1 and HIV-2
When said, the term "HIV" usually refers to HIV-1
The HIV virus affects human bodies by targeting CD4+ T cells, which are a type of blood cell
CD4+ T cells help us defend our bodies against diseases Basics of HIV In West Africa, a type of chimpanzee is to be believed to be the origin of the human HIV virus
Chimpanzees have the older version of our HIV virus, the Simian Immunodeficiency Virus, or SIV
Scientist believed that when people were hunting chimpanzees for food, one of them were infected with SIV and the infected blood infected one of the hunters
The virus then mutated to fit huan bodies and the HIV virus is made
The first recorded HIV infection in a human was in 1959 in a man from the DRC (Congo) The Origin of HIV Basics of HIV (cont'd) In this picture, you can see a CD4+ T
blood cell (pink) being infected by the
HIV virus (green) http://www.cdc.gov/hiv/topics/basic/index.htm#hiv http://www.avert.org/apps/media_gallery/files/images/115/the-structure-of-hiv-web.gif In this picture, the basic parts of a human immunodeficiency virus is shown. The Origin of HIV (cont'd) http://www.cdc.gov/hiv/resources/qa/definitions.htm The origin of the human HIV virus
is believed to have come from a chimpanzee shown here On the left is an actual picture of the SIV virus from chimpanzees. http://www.bio.fsu.edu/faculty-roux.php In 1986, HIV-2 was isolated from an infected person from South Africa
It has the same type of infection like HIV-1
HIV-2 is not as bad as HIV-1 because it grows slowly and the effect of the virus is lower
People with HIV-2 are less infectious but when time passes, it increases
Most of the people infected with this virus is from Africa HIV-2 HIV Primary Symptoms of HIV The early symptoms of HIV is very similar to a flu
The symptoms listed below are signs for primary HIV infection
Early symptoms may include:
fever
muscle soreness
sore throat
headache
rashes
mouth or genital ulcers
swollen lymph nodes
diarrhea
night sweats Treatments While there are no cures for HIV/AIDS yet, there are a number of treatments that can control the disease.
One medication that can control the disease is Sustiva, a non-nucleoside reverse transcriptase inhibitor. This type of medication prevents HIV proteins from copying itself; thus, helping to prevent further damage.
Another well known treatment for HIV/AIDS is Fuzeon, an entry/fusion inhibitor drug. This drug is extremely beneficial because it prevents HIV'S entry into CD4+ T cells. When the HIV virus keeps on destroying CD4+ T cells and replicating, more serious and chronic symptoms might occur
These symptoms are:
fever
fatigue
diarrhea
weight loss
cough
shortness of breath
white spots on tongue
pneumonia Symptoms of HIV (as it gets worse) Symptoms of HIV (cont'd) Side Effects of HIV/AID drugs http://www.mayoclinic.com/health/hiv-
aids/DS00005/DSECTION=treatments-and-drugs AIDS Basics of AIDS AIDS is an abbreviation for Acquired Immunodeficiency Syndrome
This is the late stage of an HIV infection
This disease is not heritable, hence the name "acquired"
AIDS occurs when the HIV virus has killed off most of the CD4+ T cells and the body is having a hard time fighting off different diseases and cancers
People infected with the HIV virus can enter AIDS in just a few years
Right now, people can actually live a longer time with HIV before they arrive to this stage AIDS Symptoms of AIDS The symptoms listed below can show when a person with HIV has progressed through the disease and entered AIDS
Symptoms include:
soaking night sweats
shaking chills
fever higher than 100 degrees Celsius for a few weeks
chronic diarrhea
unusual white spots in tongue and mouth
persistent fatigue
distorted vision
skin bumps and rashes Basics of AIDS (cont'd) http://www.webmd.com/hiv-aids/guide/hiv-symptoms http://upload.wikimedia.org/wikipedia/commons/3/3c/Kaposi's_Sarcoma.jpg Basics of AIDS (cont'd) The side effects of using HIV/AIDS drugs include:
diarrhea
collection of fat on the back
weakness
nausea http://health.nytimes.com/health/guides/disease/aids/overview.html http://aids.gov/hiv-aids-basics/hiv-aids-101/statistics/ Pictured on the left is Kaposi Sarcoma. If you have AIDS, you have a higher risk of getting this disease. http://upload.wikimedia.org/wikipedia/commons/3/3c/Kaposi's_Sarcoma.jpg Symptoms of HIV (cont'd) One symptom of HIV, as pictured on the left, is swollen lymph nodes Weight loss in another symptom of HIV http://www.medimanage.com/Images/weighing%20scale%20fat%20man.JPG Again, some of the symptoms of AIDS are usually normal to a person not infected with HIV
Remember, you can only get AIDS if you are infected with HIV
In order to figure out if you have AIDS or not, you must consult a doctor to diagnose you with it Symptoms of AIDS Ways HIV/Aids can spread:
unprotected sex
sharing needles to inject drugs/ steroids
sharing needles/equipment to pierce or tattoo
touching infected fluids
Now these ways only give you HIV if the person you have intercourse with has HIV, or if the person you shared needles with have HIV N Treatments (cont'd) https://www.sustiva.com/images/sustiva.jpg Two of the most famous HIV medications are pictured above http://www.fuzeon.com/Fuzeon/WebResources/images/patient/Fuzeon_logo_large.gif 1.7 million people have been diagnosed with HIV/AIDS
One in five people are living with this disease and are not aware
17,000+ people died in the U.S alone from HIV/AIDS in 2009
Gay and bisexual men are 61% accounted for the infections in 2009
Every 9.5 minutes someone is infected with HIV. Having protected sex by using condoms
Not using shared or used needles when performing piercing/tattooing
Use sterile needles when performing piercings and tattoos
Being cautious when helping someone who has HIV/AIDS that is injured and bleeding
Avoid touching any bodily fluids
Do not share razors
