The viral load of AIDS is usually detected at a lower limit of 20copies/ml, and the AIDS virus cannot be detected in a healthy person. In contrast, the viral load of HIV can be detected in a patient about 7-10 days after infection. At the beginning of the infection, the viral load is not very high, but as the virus continues to replicate in the body, the HIV viral load will continue to rise. When the patient enters the AIDS stage, the viral load in the patient’s body will be very high, reaching 10^5, 10^6, or even 10^7. By taking antiviral drugs to inhibit the replication of the virus, the virus in the patient’s body can be suppressed to less than 20copies/ml.
