How AIDS are caused?

AIDS

AIDS is a chronic life-threatening disease caused by a virus that causes deficiencies in the immune system in humans.

How does HIV work?

HIV robs the body of its ability to fight and resist viruses, germs, and fungi by infecting the immune system,

making the body vulnerable to various diseases.

AIDS exposes the human body to certain types of cancer and infections it could have fought and overcome,

such as pneumonia, meningitis, the virus and the infection it causes with human immunodeficiency virus -HIV.

Acquired immunodeficiency syndrome is a definition of AIDS in its more advanced stages.

Some 39.5 million people around the world are now living with HIV despite aids being discouraged in several countries around the world,

but the prevalence of AIDS remains the same and has even increased in others.

Operations through which HIV will not transmit

In order for HIV infection to occur, infected blood, contaminated semen, or contaminated vaginal discharge must enter the body,

so HIV infection does not occur through normal daily contact with an HIV-infected person,

such as hugs, kisses, dancing or shaking hands.

MECHANISM FOR HIV INFECTION

White blood cells usually attack and destroy alien organisms that invade the body

where this reaction is organized and coordinated by white blood cells called lymphocytes -CD4.

These T lymphocytes are also the central target of HIV,

which attacks and penetrates into these cells,

and after the success of HIV by penetrating these cells,

it introduces its genetic material into it and in this way doubles itself.

New cloned AIDS viruses begin to exit the host lymphocytes and enter the bloodstream,

where they begin to search for new cells to attack them.

Meanwhile, host lymphocytes and nearby healthy T cells die from the effects of the attacking HIV virus,

a periodic phenomenon that repeats itself over and over again.

This is how millions of new HIV cells increase daily,

and at the end of this process the number of T cells decreases,

even to a serious immunodeficiency, which means that the body is unable to resist the viruses and pathogenic germs that attack it.

Groups most at risk of AIDS

Any person of any age of any sex can live with HIV, but the risk of HIV infection increases when:

  • Having unprotected sexual relations with many people, and the degree of risk does not vary whether the person is
  • having sex with the opposite sex, with the same sex, or with both sexes, unprotected sexual relations means
  • establishing sexual intercourse without a condom.
  • Having sex with an HIV-positive partner.
  • Someone with another infectious sexual disease, such as syphilis, herpes, chlamydia, gonorrhea and viral vaginitis.
  • Frequent use several times for joint injections and needles when using intravenous drugs.
  • There is not enough of a gene (CCL3L1) that helps fight HIV.
  • Newborn children and infants of HIV-positive mothers, but did not receive protective treatment.

The symptoms of AIDS

Symptoms of AIDS vary from case to case, depending on the in-kind stage of AIDS.

  • Symptoms of early stage inflammation
    In the early stages of HIV exposure, there may be no symptoms or signs of AIDS, although it is very common in AIDS to develop flu-like symptoms and quickly disappear after two to four weeks from the moment of exposure to HIV.

Symptoms of AIDS may include:

  • High body temperature.
  • Swelling in the lymph nodes area.
  • Rash.

if you exposed to HIV,

HIV transmits to other people even if they do not show any symptoms of AIDS,

once HIV enters the body until the immune system is under attack.

HIV reproduces and doubles itself within the lymph nodes,

thus starting with a slow destruction of lymphocytes T CD4,

the white blood cells responsible for coordinating all immune system processes and activities.

Symptoms of advanced stage of inflammation

You may not have any symptoms in the advanced stages of AIDS within one to nine years, and sometimes even more.

In the meantime, however, HIV continues to multiply and multiply itself,

as well as systematically destroying immune system cells,

at this stage some chronic AIDS symptoms may appear in the patient, such as:

  • Bulge in the lymph nodes.
  • diarrhea.
  • Weight loss.
  • High body temperature.
  • cough
  • Tight breath.

Symptoms of the final stages of inflammation

In the latter stages of AIDS and HIV symptoms, which are 10 years and more than the first time exposed to HIV, the most serious symptoms of AIDS begin to appear and inflammation becomes a case of being called AIDS.

In 1993, the Centers for Disease Control and Prevention in the United States of America developed a new definition of AIDS,

which states:

AIDS is a disease if we found HIV in the body,

we can confirm it if the results of tests show antibodies to HIV in the blood accompanied by one of the following AIDS symptoms:

Opportunistic infection:

Occurs when the immune system is weak or infected,

as in the case of Pneumocystis carinii pneumonia -PCP.

Lymphocytes:

200 or less, with a healthy value of 800 to 1,200.

As AIDS develops and worsens, the damage to the immune system becomes more and more weakened,

making the body an easy prey for opportunistic infections.

Symptoms of AIDS and some of these infections include:

  • Excessive night sweating.
  • Chills or fever above 38°C last for several weeks.
  • Dry cough and tightness.
  • Chronic diarrhea.
  • Permanent white dots or strange wounds on the tongue and in the mouth.
  • headache.
  • Confusion or vision disorder.
  • loss weight.

At a more advanced stage of AIDS, additional symptoms can appear, such as:

  • inexplicable permanent fatigue.
  • Excessive night sweats.
  • Chills or fever above 38°C last for several weeks.
  • Bulges in the lymph nodes last for more than three months.
  • Chronic diarrhea.
  • Permanent headache.

HIV infection also increases the risk of certain types of cancer,

particularly Kaposi’s Sarcoma, larynx cancer and lymphoma, although the risk of developing these diseases can be reduced by preventive treatments.

Aids symptoms in children

The symptoms of AIDS in the child include:

  • Problems with weight gain.
  • Growth problems.
  • Traffic problems.
  • Slowing mental development.
  • Common inflammatory diseases such as ear infections, inflammation of the lungs, tonsillitis.

Causes and risk factors for AIDS

AIDS
AIDS

HIV infection may occur in a number of ways, including:

  • Sexual intercourse

They are the main causes of AIDS and HIV infection can be caused through vaginal,

oral or sexual contact with an HIV-positive partner when one of these things enters the body,

such as blood, semen or vaginal discharge.

The common use of sex toys that have not been washed, cleaned or not wrapped in a clean condom between use and the other transmits infection where HIV lives in semen or vaginal discharge into the body in sexual intercourse through small wounds or lacerations sometimes found in the vagina or rectum.

If someone is pregnant with another infectious sexual disease,

they are more likely to be infected with HIV,

and contrary to what researchers have thought in the past,

even women who use a semen pesticide are also at risk of contracting HIV.

This is because this semen pesticide alerts the inner mucosa of the vagina,

which can cause cracks and ruptures through which HIV can be carried out into the body.

HIV infection from inflamed blood

In some cases, HIV can be transmitted by blood or blood derivatives given to a human being by intravenous injection,

which is one of the widespread causes of AIDS.

Since 1985,

hospitals and blood banks in the United States have been testing donated blood to detect any HIV infections that may be in it,

and these tests have significantly reduced the risk of EXPOSURE to HIV from intravenous transmission as well as improved screening and liquidation of donors.

  • Injection needles
    HIV is easily transmitted by inflamed needles or injections that touch contaminated blood, as the use of common intravenous injection tools increases the risk of exposure to HIV and other viral diseases, such as hepatitis.

The best way to prevent HIV infection is to refrain from using intravenous drugs, but if this possibility is not available, the risk of infection can be reduced by using one-time and sterile injection tools.

  • Occasional needle prick: The likelihood of HIV transmission between HIV-positive people and medical staff with an occasional needle prick is very low, and specialists tend to estimate the probability by less than 1%.
  • Mother-to-child transmission of HIV: Statistics show that about 600,000 young children are infected with HIV each year, both during pregnancy and as a result of lactation, but the risk of infection with HIV when the mother is treated for HIV during pregnancy is very significantly lower.

In the United States of America, the majority of women undergo early testing for HIV antibodies and are available for retroviruses.

However, the situation in developing countries is different,

with the majority of women lacking awareness of their health conditions and the likelihood of contracting HIV,

and where the opportunities and possibilities for AIDS treatment are often very limited or not available at all.

When medications are not available,

it is preferable to give birth by Caesarean section instead of regular vaginal delivery,

and other possibilities and alternatives such as vaginal sterilization have not proved effective.
