Introduction
Basic knowledge for preventing HIV infection includes practicing safe sex consistently, avoiding sharing of needles, using blood products properly, implementing effective mother-to-child transmission prevention, and maintaining good personal hygiene and protection. Strict adherence to these measures can significantly reduce the risk of infection. If you have engaged in high-risk behaviors or experience symptoms suggestive of HIV, it is recommended to seek medical attention and testing promptly. Use condoms throughout sexual intercourse.

Basic knowledge for preventing HIV infection includes practicing safe sex, avoiding sharing of injection syringes, using blood products responsibly, implementing effective mother-to-child transmission prevention, and enhancing personal hygiene and protection. Strictly following these measures can significantly reduce the risk of infection. If you have engaged in high-risk behaviors or experience symptoms suggestive of HIV, it is recommended to seek medical testing promptly.

1. Practice Safe Sex: Consistently and correctly use condoms during all sexual activities. Avoid unprotected high-risk sexual behaviors and refrain from unprotected contact with individuals infected with HIV to reduce the risk of sexual transmission.

2. Avoid Sharing Injection Equipment: Refrain from injecting drugs and never share syringes, needles, or other injection equipment with others. Use sterile, disposable instruments during medical procedures to prevent HIV transmission through blood exposure.

3. Use Blood Products Responsibly: Seek medical care only at正规 medical institutions. Avoid using blood or blood products of unknown origin. Before receiving blood transfusions or organ transplants, ensure that all relevant products have been tested for HIV.

4. Prevent Mother-to-Child Transmission: Women of childbearing age who are living with HIV should plan pregnancies under medical guidance. They should receive standardized antiretroviral prophylaxis during pregnancy, childbirth, and breastfeeding. Newborns should be tested and provided timely interventions after birth.

5. Enhance Personal Hygiene and Protection: Do not share personal items such as toothbrushes or razors that may be contaminated with blood. In medical settings, if skin or mucous membranes are exposed to another person’s blood or bodily fluids, follow proper decontamination procedures immediately.

It is important to actively learn about HIV prevention and control, avoid stigmatizing people living with HIV, and strengthen self-protection awareness. Avoid sharing items that could cause skin injuries, maintain a healthy lifestyle, and get tested promptly after any high-risk behavior to ensure early detection and early intervention.

What percentage should adherence to antiviral medication for HIV treatment achieve?
Adherence to antiviral therapy for HIV must reach over 95%, which is a critical requirement for suppressing viral replication and controlling disease progression; falling below this level significantly compromises treatment effectiveness. If long-term adherence is inadequate or adverse drug reactions occur, prompt medical consultation is recommended to adjust the treatment regimen. This level of adherence means missing no more than 1–2 doses per month.

Can people with HIV receive the COVID-19 vaccine?
In general, whether HIV patients can receive the COVID-19 vaccine should be determined based on their immune status. Those with stable treatment and a CD4 cell count ≥200 cells/μL may be vaccinated, while vaccination should be postponed in cases of severe immunosuppression or concurrent acute infection. Patients should consistently adhere to standardized antiviral therapy and undergo regular monitoring of CD4 cell count and viral load.
