Why HIV stays in human body even after antiviral therapy?

HIV stands for  human immunodeficiency virus, it attacks the human body and make your immune system very weak and if you not treat it, it will become AIDS .HIV is spread through a virus and this virus is caused by sexual contact and also by infected blood .HIV virus destroys your T cells in your body and make you so weak.


Many researches made studies that why HIV stays in human body even after antiviral therapy. This is due to CD73 and T cells because CD73 is apparently responsible for the mechanism of cell movement and cell association. And if our body lacks these proteins then our body do not able to make such T cells which fight against HIV  then our body can not fight against the virus .


The backgrounds of HIV have come from a certain chimpanzee in Central Africa. This is a outcome of zoonotic transmission from the primate variety of the virus called simian immunodeficiency virus.




HIV attaches to Helper T cells and merges with the Helper T cells and send the genetic information into the cell. The HIV contains  contains a genome composed of RNA molecule.


Structure of HIV virus:



The HIV virus belongs to Retroviridae family. HIV virus discovered in the year 1983.Is HIV virus enveloped or nonenveloped the answer is HIV virus is enveloped virus. HIV virus effects o immune syetem.HIV virus  genome size is 9.2kb.HIV virus  is a host of helper T cells and HIV is a retrovirus. HIV virus incubation period is less than one month. HIV virus replicates itself i host cell.


HIV virus preferentially infects CD4 cells. The risks of HIV virus  transmission by blood is very low.HIV destroys white blood cells and then weaken the immune system.


HIV virus is the deadliest epidemic of our time .Almost 42 million people are suffering from HIV virus and 22 million people have lost their lives.

      Spoilage food more commonly referred to as food poisoning, is the result of eating contaminated, spoilage or toxic food. The most common symptoms of food poising include nausea, vomiting and diarrhea. Although it’s quite uncomfortable, food poisoning is not unusual. Food spoilage and deterioration is no accident. It is naturally occurring process. To understand how to maintain the quality of food and prevent spoilage, we need to know what can cause it. Factor that effect food spoilage. Microorganism Enzyme Air Light Insects Temperature Time     Preservative frequently involves preservation the growth of bacteria, fungi and other microorganisms. A number of methods of preservation can be used that can either totally prevent, delay or otherwise reduce food spoilage. Detection of spoilage food: The detection of food spoilage may include an appearance different from fresh food, change in color, a change

  It was rare for anyone younger than 40 to have a heart attack .Now 1 in 5 heart attack patients are younger than 40 years of age.Having a heart attack in your 20s or early . The rise in heart attack among younger people can largely be attributed to lifestyle .Overbooked schudele, pressure to compete ,constant stress and anxiety, overeating and self –medicating with alcohol and drugs take a toll on the heart. Hypertension or high blood pressure is one of the biggest trend factors for cardiovascular disease .inappropriately just like the trend in heart attacks, the occurrence of hypertension is rising faster in young adults than in older adults. High blood pressure makes your heart muscles thicker, harm your blood vessels and increases your risk of a heart attack.     Without warming,your heart stops due to an electrical disturbance that causes an abnormal heart rhythm.Heaert attacks increase the risks of sudden cardiac arrest,which can cause death without immediate treatment.
