The immune system becomes weaker, making it harder for the body to fight off infections and some kinds of <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/cancer.html/">cancers</a>.</p> <p>Most people who are diagnosed early and take medicines for HIV can live long, healthy lives.</p> <h3>What Is AIDS?</h3> <p>AIDS (acquired immune deficiency syndrome) happens after someone has had HIV for many years. In <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/aids.html/">AIDS</a>, the immune system is severely weakened. Serious infections and health problems happen.</p> <p>Medicines can help prevent HIV from developing into AIDS.</p> <h3>How Do People Get HIV?</h3> <p>HIV spreads when infected <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/blood.html/">blood</a> or body fluids (such as semen or vaginal fluids) enter the body. This can happen:</p> <ul> <li>during sex (especially anal sex and vaginal sex)</li> <li>through sharing needles for injecting <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/know-about-drugs.html/">drugs</a> or <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/safe-tattooing.html/">tattooing</a></li> <li>by getting stuck with a needle with an infected person's blood on it</li> </ul> <p>HIV also can pass from mother to child during pregnancy, childbirth, or breastfeeding.</p> <p>HIV is <strong>NOT</strong> spread through:</p> <ul> <li>pee, poop, spit, throw-up, or sweat (as long as no blood is present)</li> <li>coughing or sneezing</li> <li>holding hands</li> <li>sharing eating utensils or drinking glasses</li> </ul> <h3>What Are the Signs &amp; Symptoms of HIV and AIDS?</h3> <p>When first infected with HIV, a person may have:</p> <ul> <li>fever</li> <li>swollen glands</li> <li>painful ulcers in the mouth or around the anus or penis</li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/teens/headaches.html/">headache</a></li> <li>rash</li> <li>muscle and joint pain</li> </ul> <p>These symptoms go away in a few weeks. In the first few years after infection, someone with HIV may have mild symptoms, like swollen glands.</p> <p>Because the symptoms of HIV can be mild at first, some people might not know they're infected. They can spread HIV to others without even knowing it.</p> <p>After a few years, other symptoms start, including:</p> <ul> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/teens/diarrhea.html/">diarrhea</a></li> <li>weight loss</li> <li>increased number of infections</li> <li>infections that are more severe than is typical</li> </ul> <p>Without treatment, HIV can lead to a very weakened immune system and progress to AIDS. Illnesses that happen in AIDS are called &quot;AIDS-defining conditions.&quot;</p> <p>AIDS-defining conditions include:</p> <ul> <li>very fast and severe weight loss (called <strong>wasting syndrome</strong>)</li> <li>a lung infection called pneumocystis <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/pneumonia.html/">pneumonia</a></li> <li>Kaposi sarcoma (a type of skin cancer)</li> <li>lymphoma (cancer in immune system cells)</li> </ul> <h3>What Causes HIV and AIDS?</h3> <p>HIV destroys CD4 cells (also called T cells). CD4 cells are part of the immune system. They fight <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/care-about-germs.html/">germs</a> and help prevent some kinds of cancers.</p> <h3>How Is HIV Diagnosed?</h3> <p>Health care providers usually diagnose HIV through blood tests. Someone who has HIV is said to be &quot;HIV positive.&quot;</p> <p><a href="https://kidshealth.org/ws/RadyChildrens/en/teens/hiv-tests.html/">Tests</a> also are available without a prescription at the drugstore. You can do the test at home.</p> <h3>How Is AIDS Diagnosed?</h3> <p>HIV is diagnosed as AIDS when someone:</p> <ul> <li>has fewer than 200 CD4 cells<br />or</li> <li>develops an AIDS-defining condition</li> </ul> <h3>How Are HIV and AIDS Treated?</h3> <p>Medicines can help people with HIV stay healthy. They can also prevent HIV from progressing to AIDS.</p> <p>Health care providers prescribe a combination of different medicines for people with HIV and AIDS. They must be taken exactly as prescribed or they won't work. These medicines:</p> <ul> <li>help keep the number of CD4 cells high</li> <li>reduce the <strong>viral load</strong> of HIV (how much HIV is in the body)</li> </ul> <p>Regular blood tests will check the number of CD4 cells in the body (called the <strong>CD4 cell count</strong>) and the viral load.</p> <p>If an HIV-positive person's CD4 count gets low, doctors prescribe daily antibiotics. This prevents pneumocystis pneumonia, which happens in people with weakened immune systems.</p> <h3>Can HIV Be Prevented?</h3> <p>To reduce the risk of getting HIV, people who are sexually active should:</p> <ul> <li>use a <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/contraception-condom.html/">condom</a> every time they have sex (including vaginal, oral, or anal sex)</li> <li>get tested for HIV and make sure all partners do too</li> <li>reduce their number of sexual partners</li> <li>get tested and treated for <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/std.html/">STDs</a> (sexually transmitted diseases); having an STD increases the risk of HIV infection</li> <li>consider taking a medicine every day (called <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/prep.html/"><strong>PrEP </strong></a>or<strong> pre-exposure prophylaxis</strong>) if they are at very high risk of getting infected (for example, if they are in a sexual relationship with someone with HIV)</li> </ul> <p>For everyone:</p> <ul class="kh_longline_list"> <li>Do not inject drugs or share any kind of needle.</li> <li>Do not share razors or other personal objects that may touch blood.</li> <li>Do not touch anyone else's blood from a cut or sore.</li> </ul> <h3>Looking Ahead</h3> <p>Treatment has improved greatly for people with HIV. By taking medicines and getting regular medical care, HIV-positive people can live long and healthy lives.&nbsp;</p> <p>People with HIV need a medical care team for the best treatment and support.</p> <p>If you or <a href="https://kidshealth.org/ws/RadyChildrens/en/teens/friend-hiv.html/">someone you know</a> has HIV or AIDS it is important to:</p> <ul> <li>goes to all doctor visits</li> <li>takes all medicines exactly as directed</li> <li>goes for all follow-up blood tests</li> <li>understands what HIV/AIDS is and how it spreads</li> <li>is physically active, gets enough sleep, and eats well</li> </ul>VIH y SIDALa mayoría de las personas a quienes les diagnostican pronto esta infección y que toman medicamentos contra el VIH pueden llevar vidas largas y satisfactorias. https://kidshealth.org/ws/RadyChildrens/es/teens/std-hiv-esp.html/a7f5616b-533c-443f-b3ba-38f3e7fb35b3
