&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;PrEP for HIV prevention is not a new thing. This kind of HIV prevention method has been around since 2012 and kept improving since.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #cc99ff;&quot;&gt;&lt;strong&gt;How Does PrEP Work?&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;HIV cannot multiply on its own; it hijacks CD4 cells, a type of white blood cell that fights infections. Using an enzyme, HIV converts its RNA into DNA to replicate. PrEP medications, known as NRTIs (nucleoside/nucleotide reverse transcriptase inhibitors), block the key enzyme HIV needs to make copies of itself, helping prevent its spread in the body.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;Regular HIV testing is required before starting and during PrEP use to ensure a negative result, as taking PrEP during active HIV infection can lead to drug resistance.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #cc99ff;&quot;&gt;&lt;strong&gt;How Effective is PrEP?&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;PrEP (pre-exposure prophylaxis) is highly effective at preventing HIV when used as prescribed. It can reduce the risk of HIV transmission through sex by about 99% and. However, its effectiveness drops significantly if not taken consistently. Following the prescribed regimen is key to maximizing PrEP&#39;s protection against HIV.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;h2&gt;&lt;span style=&quot;color: #cc99ff;&quot;&gt;&lt;strong&gt;Studies Show PrEP Reduces HIV Rates&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;hr /&gt;
&lt;p&gt;&lt;span style=&quot;font-weight: 400;&quot;&gt;Like any other medication, PrEP undergoes extensive research and testing on its efficacy before approval. Studies on HIV PrEP suggest it is highly effective in preventing HIV. This information can help you decide if PrEP is the right choice for you. Consulting your doctor about PrEP&#39;s effectiveness and suitability is an essential step before starting treatment. Additionally, combining PrEP with other HIV prevention methods can enhance your overall prevention strategy.&lt;/span&gt;&lt;/p&gt;

Other studies, such as the &lt;/span&gt;&lt;a href=&quot;https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(15)00056-2/fulltext&quot;&gt;&lt;strong&gt;PROUD&lt;/strong&gt;&lt;/a&gt; &lt;span style=&quot;font-weight: 400;&quot;&gt;study, demonstrate PrEP&#39;s effectiveness in HIV prevention, suggesting that daily use can lower the risk of HIV by 99%.&lt;/span&gt;&lt;/p&gt;
