AIDS (acquired immunodeficiency syndrome) is a syndrome caused by a virus called HIV (human immunodeficiency virus). The disease alters the immune system, making people much more vulnerable to infections and diseases. This susceptibility worsens if the syndrome progresses.
HIV is found throughout all the tissues of the body but is transmitted through the body fluids of an infected person (semen, vaginal fluids, blood, and breast milk).

In this article, we explain HIV and AIDS, their symptoms, causes, and treatments.

OVERVIEW
Overview
HIV is a virus that attacks immune cells called CD-4 cells, which are a subset of T cells. AIDS is the syndrome, which may or may not appear in the advanced stage of HIV infection.

HIV is a virus.

AIDS is a medical condition.

HIV infection can cause AIDS to develop. However, it is possible to contract HIV without developing AIDS. Without treatment, HIV can progress and, eventually, it will develop into AIDS in the vast majority of cases.

CAUSES
Causes
HIV blood cell illustration
HIV can be passed from one person to another through blood-to-blood and sexual contact.
HIV is a retrovirus that infects the vital organs and cells of the human immune system.

The virus progresses in the absence of antiretroviral therapy (ART) - a drug therapy that slows or prevents the virus from developing.

The rate of virus progression varies widely between individuals and depends on many factors.

These factors include the age of the individual, the body's ability to defend against HIV, access to healthcare, the presence of other infections, the individual's genetic inheritance, resistance to certain strains of HIV, and more.

How is HIV transmitted?
Sexual transmission — it can happen when there is contact with infected sexual fluids (rectal, genital, or oral mucous membranes). This can happen while having sex without a condom, including vaginal, oral, and anal sex, or sharing sex toys with someone who is HIV-positive.

Perinatal transmission — a mother can transmit HIV to her child during childbirth, pregnancy, and also through breastfeeding.

Blood transmission — the risk of transmitting HIV through blood transfusion is extremely low in developed countries, thanks to meticulous screening and precautions. However, among people who inject drugs, sharing and reusing syringes contaminated with HIV-infected blood is extremely hazardous.

SYMPTOMS
Symptoms
For the most part, the later symptoms of HIV infection are the result of infections caused by bacteria, viruses, fungi, and/or parasites.

These conditions do not normally develop in individuals with healthy immune systems, which protect the body against infection.

Early symptoms of HIV infection
Some people with HIV infection have no symptoms until several months or even years after contracting the virus. However, around 80 percent may develop symptoms similar to flu 2–6 weeks after catching the virus. This is called acute retroviral syndrome.

The symptoms of early HIV infection may include:

fever
chills
joint pain
muscle aches
sore throat
sweats (particularly at night)
enlarged glands
a red rash
tiredness
weakness
unintentional weight loss
thrush
It is important to remember that these symptoms appear when the body is fighting off many types of viruses, not just HIV. However, if you have several of these symptoms and believe you could have been at risk of contracting HIV in the last few weeks, you should take a test
