Know About ‘HIV infection’

‘HIV infection’ – commonly known “AIDs”. HIV infection is a condition caused by the human immunodeficiency virus (HIV). The condition gradually destroys the immune system, which makes it harder for the body to fight infections.
How does HIV turn into AIDS?
Your immune system weakens as more CD4 cells are killed. You can have an HIV infection for years before it progresses to AIDS. People infected with HIV progress to AIDS when their CD4 count falls below 200 or they experience an AIDS-defining complication, such as: Pneumocystis pneumonia.

Disease Description:
Signs & Symptoms: Within a month or two of HIV entering the body, 40% to 90% of people experience flu like symptoms known as acute retroviral syndrome (ARS).
But sometimes HIV symptoms don't appear for years—sometimes even a decade—after infection.
Fever: One of the first signs of ARS can be a mild fever, up to about 102 degrees F. Fever accompanied by other usually mild symptoms, such as fatigue, swollen lymph glands, and a sore throat.
Fatigue:  The inflammatory response generated by your besieged immune system also can cause you to feel tired and lethargic. Fatigue can be both an early and later sign of HIV.
Achy muscles, joint pain, swollen lymph nodes
Sore throat and headache
Skin Rash
Weight loss
Dry cough
Pneumonia
Night sweats
Nail changes
Yeast infections: Another fungal infection that's common in later stages is thrush, a mouth infection caused by Candida, a type of yeast.
Confusion or difficulty concentrating
Cold sores or genital herpes
Tingling and weakness
Menstrual irregularities

Stages Of HIV:
HIV infection comes in three stages.
The first stage is called acute infection or seroconversion, and it typically happens within two to six weeks after exposure or becoming infected. This is when the body's immune system puts up a fight against HIV.
After the first seroconversion period, the immune system loses the battle with HIV and symptoms go away. HIV infection goes into its second stage, which can be a long period without symptoms, called the asymptomatic (or latent ) period. This is when people may not know they are infected and can pass HIV on to others. This period can last 10 or more years.
AIDS (acquired immune deficiency syndrome) is the advanced stage of HIV infection. When the CD4 T-cell number drops below 200, people are diagnosed with AIDS.

Treatment Options:  No cure exists, but medications can dramatically slow the disease's progress.
Antiviral drugs are used to prevent infections. E.g:  Zidovudine (Retrovir), Emtricitabine/tenofovir, Lamivudine/zidovudine, Raltegravir, Efavirenz/emtricitabine/tenofovir (Atripla), Delavirdine, Abacavir/lamivudine/zidovudine (Trizivir), Efavirenz (Sustiva), Nevirapine (Viramune), Tenofovir (Viread), Maraviroc, Stavudine (Zerit), Lamivudine (Epivir), Abacavir (Ziagen), Etravirine (Intelence), Emtricitabine (Emtriva), Abacavir/lamivudine (Epzicom)
Other treatments: Enfuvirtide, Darunavir (Prezista), Amprenavir (Lexiva), Ritonavir (Norvir), Atazanavir (Reyataz)
