CD4, sometimes called T-cells or T-helper cells, is a type of white blood cell responsible for regulating the immune system and fighting off various pathogens. It works to produce the immune substances the body needs to fight off germs, bacteria, fungi, and viruses.
When a healthy person is infected with HIV, the virus enters the body and destroys CD4 cells, then copies itself inside those CD4 cells. When the HIV inside a CD4 cell is released all at once, this exponential replication lets the virus band together and rapidly attack other CD4 cells that are still healthy. Not long after HIV infection, your CD4 level is likely to drop rapidly as well.
HIV Treatment and CD4
Today, Thailand provides treatment to people with HIV in every case, no matter what your CD4 count is, because the sooner treatment begins, the better HIV can be controlled. When a person living with HIV receives antiretroviral therapy, their CD4 count rises steadily. If the patient takes their antiretroviral medication every day and on time, CD4 will begin to stabilize at around 500 to 600, depending on each person's physical condition.

What CD4 Level Is Considered Concerning?
A CD4 level below 200 carries a risk of various infections known as opportunistic infections, which result from a weakened immune system and can progress to AIDS, which may become severe enough to be life-threatening. If raising your CD4 quickly proves difficult, you should take good care of yourself: exercise, eat well, keep a calm mind, take your medication continuously, quit all addictive substances, and reduce anxiety. All of this will help you enjoy a better quality of life.
Treatment with HIV antiretroviral medication can help raise the CD4 level of people living with HIV. Those who take their antiretroviral medication consistently will see their CD4 level rise, helping them live longer, healthier lives.
