AIDS and its causes

 It is scientifically named HIV (Human immunodeficiency virus infection) or AIDS (acquired immunodeficiency syndrome). This is a disease that affects the human immune system. its early symptoms seems like those of a common cold with throat inflammation runny nose enlargement of some lymph nodes headache nausea vomiting but soon these symptoms all disappears after 1 to 2 weeks followed by an asymptomatic period caked the latency period whose duration may vary largely between different cases as it may last for several years followed by the appearance of the symptoms of the actual AIDS which include many symptoms but the most important thing of these is that the body immunity is affected to very high degree that makes the patient more susceptible to different viral bacterial or fungal infections leading to many and many different complications including pneumonia, pneumocyctis, respiratory tract infections, esophageal Canadianism and many many other infections affecting various body organs

Here we are going to concentrate  in this article about the causes of this disease as we said it is viral infection that  affect the human immune systems. The main  roots through which this virus transmits are 
1)sexual intercourse  
2)blood transfusion 
3) using hypo dermal infected syringes 
4)mother to child during pregnancy  
We will talk in details about each kind of transmission and the percentage of disease occurrence through each.

Sexual transmission

It’s the main and the most frequent root of transmission of this virus due to the presence of the virus in the mucus membranes either oral or vaginal and it is most transmitted due to the normal intercourse between two of different sex also its transmuted through oral sex or anal sex or even through homosexual intercourse

Something one can prevent such transmission through heterosexual intercourse is by using condoms which prevent the direct contact between organs.

Blood transfusion

Infection through this root is rare but it may occur specially in low income and poor health care countries where there is no sufficient laboratory tests are made on the blood that is transfused causing direct infection to the receiving patient.

Hypo dermal injections using contaminated syringes

In this cases the infection occur when one disposable syringe is used among two patients one which is hosting the virus and as this virus is transmitted through blood or any of the blood fluids so certainly this syringe will cause direst infection but also I will stress on that this type of transmission is rare.

Mother child transmission during pregnancy

This occur when a female infected woman get pregnant and due to the normal placental blood connection between the mother and the fetus the virus directly transmit thorough the placenta to the child leading to giving birth of an infected child.

But I would like to mention an important notice concerning AIDS viral infection  This virus is transmitted completely through exposure to feces, nasal secretion, saliva, tears , sweat and sputum or urine unless these are contaminated with infected blood also its not transmitted through breathing.
