In one sentence, describe what the following article is about: This once-a-day pill can greatly reduce the risk of HIV infection, but only if used as prescribed. PrEP is recommended for people who do not have HIV, but are exposed to HIV-positive sexual partners or objects regularly.  Visit a doctor every 3 months when taking PrEP, to check your HIV status and monitor for renal (kidney) problems. There are no known effects of PrEP on a fetus, but there have not been many studies. Talk to your doctor if you are on PrEP and become pregnant. PrEP is only able to prevent you from contracting HIV and not other STDs. Even while taking PrEP, it is important to continue using protection while having sex. If you think you've been exposed to HIV, talk to a medical worker at an HIV clinic or hospital immediately. If you start taking PEP drugs as soon as possible, and no later than 72 hours after exposure, there is a chance that you will fight off the HIV infection. You must take the drug (or more typically two or three drugs) daily for 28 days, or as directed by the health worker.  Because this is not a guaranteed method of protection, you should still be tested for HIV after the drugs are done, and a second time 3 months later. Until you test negative, tell your sexual partners that you may have HIV. If you are exposed frequently, take PrEP as a constant daily pill instead, as described above. HIV-positive people who take antiretroviral drugs can have significant success managing their infection levels. Some of these people consider this ongoing treatment an important tool to help prevent spreading the infection to their HIV-negative partners. Researchers and workers in the HIV prevention community are divided on how effective this message is. Some studies show that people who use "treatment as prevention" (TasP) are more likely to skip other forms of protection, such as condoms. While treatment can certainly reduce the risk of transmitting the infection, it is not a guarantee. Each person involved should receive regular testing to measure the risk involved. Someone infected with HIV should receive regular testing to determine the "viral load," or concentration of HIV in the bodily fluids. With constant treatment, HIV positive people can have "undetectable viral loads." It's important to understand that someone with an undetectable viral load still has HIV, and may still be able to transmit HIV to a sexual partner. While some studies show very promising results about low (or potentially nonexistent) transmission rates, more studies are needed for accurate risk assessment. Some people with undetectable viral loads in their blood may have much greater viral loads in their semen or other bodily fluids. All of the suggestions listed here are risk mitigation techniques. There is no such thing as completely safe sex or safe drug use. Things can go wrong. Accidents happen. Whether or not you use protection while having sex, you should get tested for HIV every 3 to 6 months. If you engage in any behaviors that increase your risk of contracting HIV, such as unprotected sex or sharing needles with someone, seek the advice of a medical professional as soon as you can in order to determine the best course of action.
Summary: Consider Pre-Exposure Prophylaxis (PrEP) for long-term protection. Use Post-Exposure Prophylaxis (PEP) immediately after exposure. Understand treatment as prevention. Understand undetectable viral loads. Get tested regularly.

We often do things to ourselves that we would never dream of doing to someone we care about. For instance, when’s the last time you called a friend ugly, told them they weren’t good enough, or discouraged them from following their dreams? Whatever you believe to be respect, apply it to yourself. Don't insult or harm yourself, no matter how bad you feel. This kind of treatment is only bound to make you feel worse. Here are some other ways to treat yourself with basic respect:  Don't steal from yourself, such as recklessly putting everything on credit; you're essentially taking money from your future self, because you'll have to pay up eventually.  Be honest with yourself instead of being in denial about what you really want.  Think for yourself by developing your own sources of knowledge and doing research, instead of just following the opinions of others. When you make an effort to keep your body in good working order, you'll not only feel better physically, but you'll also feel a sense of pride. Respecting your body also means not insulting it for what it is, naturally. Make an effort to get fit and stay healthy, but don't trash yourself over the things you can't control, like your proportions. Focus on the things you can change and improve, and do it because it feels good, not because you think you're not "good enough" the way you are. This doesn't mean that going to the gym and looking amazing will automatically lead you to have high self-respect. But it does mean that if you don't put any time or care into your appearance, that you'll start to lose respect for who you are. Respecting yourself does not mean thinking that you are perfect and that there is absolutely nothing that you need to work on and improve. It means being able to accept the things that you cannot change about yourself, while working to address the things that you need to work on. Take some time to really think about yourself and to consider the areas you'd like to work on the most; maybe you would like to improve your listening skills, or you would love to handle life's daily little stresses a lot better, or you would like to have a more balanced approach when making the people around you happy without sacrificing your own needs.  Make a plan to make some headway in these departments, and soon, you'll be on your way to having more respect for yourself. Make a list of areas you’d like to improve. Take note when you make improvements, however small. It’s important to write down your small and big victories. Of course, changing behaviors and the thoughts and feelings associated with those behaviors takes more than a day or two; it takes a big commitment and persistence. But taking the first steps to become a person that you respect more will make you feel more confident about who you are. Improving yourself means taking the steps to try new things and to open your mind to new possibilities. Improving yourself can mean taking a yoga class, volunteering, spending more time learning lessons from the elders you care about, learning to see multiple perspectives about a situation, reading the news, and striving to learn new things.
