預防 HIV 感染 5 關鍵

5 Keys to Preventing HIV Infection

1. 避免具風險的性行為：性行為全程使用保險套、避免合併使用成癮性物質

Avoid risky sexual behaviors: use condoms during all sexual activities and avoid the combined use of addictive substances

2. 暴露前預防性投藥 (PrEP)：HIV 篩檢陰性者可規律地服用 PrEP，維持體內藥物濃度來預防 HIV 感染。

Pre-exposure prophylaxis (PrEP): People who screen negative for HIV can take PrEP regularly to maintain drug levels in the body to prevent HIV infection.

3. 暴露後預防性投藥 (PEP)：類似事後避孕藥的概念，在發生有風險的暴露後的 24-72 小時內開始服用，連續服用 28 天，也可以降低八成感染的風險。

Post-exposure prophylaxis (PEP): A concept similar to the morning-after pill, when taken within 24-72 hours of a risky exposure and continued for 28 days, it can also reduce the risk of infection by 80%.

4. 定期接受 HIV 篩檢：高危險族群應定期接受篩檢，瞭解自己的健康狀態，才能及時銜接治療，或使用預防性投藥等。

Receive regular HIV screening: High-risk groups should receive regular screening to understand their health status so that they can promptly receive treatment or use preventive medication.

5. 感染者積極用藥治療：HIV 感染者確診後積極服用抗病毒藥物治療，可以將體內病毒量壓制到測不到的狀態，就不會再將病毒傳染給他人，稱作 U=U(Undetectable=Untrasmittable) 測不到 = 不具傳染力。

Infected people should actively take medication for treatment: HIV-infected people should actively take antiviral medication after being diagnosed. This can suppress the amount of virus in the body to an undetectable state and prevent the virus from being transmitted to others. This is called U=U (Undetectable=Untrasmittable). ) Undetectable = not contagious.
