HIV stands for human immunodeficiency virus. HIV harms your immune system by destroying a type of white blood cell that helps your body fight infection. This puts you at risk for other infections and diseases.

AIDS stands for acquired immunodeficiency syndrome. It is the final stage of infection with HIV. It happens when the body's immune system is badly damaged because of the virus. Not everyone with HIV develops AIDS.

HIV is spread through certain body fluids from a person who has HIV. This can happen:

• By having unprotected vaginal or anal sex with a person who has HIV. "Unprotected" means not using condoms or medicine to treat or prevent HIV. This is the most common way that it spreads.
• By sharing drug needles.
• Through contact with the blood of a person with HIV.
• From mother to baby during pregnancy, childbirth, or breastfeeding.

Anyone can get HIV, but certain groups have a higher risk of getting it:

• People who have another sexually transmitted disease (STD). Having an STD can increase your risk of getting or spreading HIV.
• People who inject drugs with shared needles.
• Gay and bisexual men.
• Black/African Americans and Hispanic/Latino Americans. They make up a higher proportion of new HIV diagnoses and people with HIV, compared to other races and ethnicities.
• People who engage in risky sexual behaviors, such as not using condoms or medicine to prevent or treat HIV.

Factors such as stigma, discrimination, income, education, and geographic region can also affect people's risk for HIV.

The first signs of HIV infection may be flu-like symptoms:

• Fever
• Chills
• Rash
• Night sweats (heavy sweating during sleep)
• Muscle aches
• Sore throat
• Fatigue
• Swollen lymph nodes
• Mouth ulcers

These symptoms may come and go within two to four weeks. This stage is called acute HIV infection.

If the infection is not treated, it becomes chronic HIV infection. Often, there are no symptoms during this stage. If it is not treated, eventually the virus will weaken your body's immune system. Then the infection will progress to AIDS. This is the late stage of HIV infection. Because your immune system is badly damaged, your body cannot fight off other infections, called opportunistic infections (OIs). OIs are infections that happen more frequently or are more severe in people who have weakened immune systems.

Some people may not feel sick during the earlier stages of HIV infection. So the only way to know for sure whether you have HIV is to get tested.

A blood test can tell if you have HIV infection. Your health care provider can do the test, or you can use a home testing kit. You can also use the CDC Testing Locator to find free testing sites.

There is no cure for HIV infection, but it can be treated with medicines. This is called antiretroviral therapy (ART). ART can make HIV infection a manageable chronic condition. It also reduces the risk of spreading the virus to others.

Most people with HIV live long and healthy lives if they get ART as soon as possible and stay on it. It's also important to take care of yourself. Making sure that you have the support you need, living a healthy lifestyle, and getting regular medical care can help you enjoy a better quality of life.

You can reduce the risk of getting or spreading HIV by:

• Getting tested for HIV.
• Choosing less risky sexual behaviors. This includes limiting the number of sexual partners you have and using latex condoms every time you have sex. If your or your partner is allergic to latex, you can use polyurethane condoms.
• Getting tested and treated for sexually transmitted diseases (STDs).
• Not injecting drugs.
• Talking to your health care provider about medicines to prevent HIV:
  • PrEP (pre-exposure prophylaxis) is for people who don't already have HIV but are at very high risk of getting it. PrEP is daily medicine that can reduce this risk.
  • PEP (post-exposure prophylaxis) is for people who have possibly been exposed to HIV. It is only for emergency situations. PEP must be started within 72 hours after a possible exposure to HIV.

The prostate is a gland in the male reproductive system. It lies just below the bladder. It makes fluid that is part of semen.

There are many types of prostate diseases:

• Prostatitis is inflammation (swelling and pain) in the prostate gland. It's the most common type of prostate problem in people under than age 50. There are different types:
  • Chronic prostatitis is also called chronic pelvic pain syndrome. It's the most common type of prostatitis.
  • Acute bacterial prostatitis starts suddenly from a bacterial infection and is treated with antibiotics. It is not common.
  • Chronic bacterial prostatitis happens when a bacterial infection keeps coming back. The symptoms usually start slowly. It may take longer to treat than acute bacterial prostatitis.
  • Asymptomatic prostatitis has no symptoms and usually doesn't need treatment. You may learn you have it after having tests for other health problems.
• Enlarged prostate is also called benign prostatic hyperplasia (BPH). The prostate gland tends to grow larger with age. That's why enlarged prostate is very common in older people and rare in those who are under age 40. When the prostate grows larger, it may press on your urethra and cause problems with urination.
• Prostate cancer happens when cancer cells form in the prostate gland. Prostate cancer is a common type of cancer in those aged 50 and older. Most prostate cancers grow slowly and may never cause health problems. But certain prostate cancers are serious.

Anyone with a prostate can develop prostate problems. But some people are at higher risk.

You may be more likely to develop prostatitis if you have:

• A lower urinary tract infection, also called a UTI. An infection in your lower urinary tract (bladder and urethra) may lead to acute or chronic bacterial prostatitis.
• Nerve damage in your lower urinary tract from surgery or an injury. This may lead to chronic prostatitis.
• Emotional stress, which can lead to chronic prostatitis.

You may be more likely to develop an enlarged prostate (BPH) if you:

• Are age 40 or older.
• Have family members who have had BPH.
• Have certain health conditions such as:
  • Obesity.
  • Heart disease and problems with blood circulation.
  • Type 2 diabetes.
• Don't get enough physical activity.

You may be more likely to develop prostate cancer if you:

• Are older than age 50.
• Have a parent, sibling, or child who has or had prostate cancer.
• Are African American.

The symptoms of prostate problems include:

• Needing to urinate a lot.
• Needing to rush to the bathroom, but not being able to urinate or only going a little.
• Leaking or dribbling urine.
• Having a weak urine stream.

Other symptoms depend on the type of prostate problem you have and may include:

• Not being able to urinate at all. This is a medical emergency.
• Any problems, starting or controlling urine flow.
• Waking up often to urinate.
• Blood in your urine or urine that has an unusual smell or color.
• Fever, chills, or body aches.
• Great discomfort or pain:
  • While urinating or after ejaculation.
  • In your abdomen (belly), between your scrotum and anus, or in your scrotum or penis.

Contact your provider if you have any of these symptoms.

To find out if you have a prostate problem, your provider will:

• Ask about your medical history and symptoms.
• Ask about your family health history.
• Do a physical exam. The exam may include a digital rectal exam (DRE) of your prostate. In a DRE, your provider inserts a gloved finger into your rectum to feel the general size and condition of your prostate.
• Order tests, if needed. Tests may include:
  • Blood and urine tests to look for infection.
  • Urodynamic testing to see how well you can hold and release urine.
  • Cystoscopy to look inside your urethra and bladder.
  • Ultrasound pictures of your prostate and urinary tract.
  • A PSA blood test (prostate-specific antigen test).
  • Prostate biopsy to diagnose or rule out cancer.

Treatment depends on what prostate disease you have and which symptoms bother you most.

The urinary system is the body's drainage system for removing wastes and extra water. It includes two kidneys, two ureters, a bladder, and a urethra. Urinary tract infections (UTIs) are the second most common type of infection in the body.

You may have a UTI if you notice:

• Pain or burning when you urinate
• Fever, tiredness, or shakiness
• An urge to urinate often
• Pressure in your lower belly
• Urine that smells bad or looks cloudy or reddish
• Pain in your back or side below the ribs

People of any age or sex can get UTIs. But about four times as many women get UTIs as men. You're also at higher risk if you have diabetes, need a tube to drain your bladder, or have a spinal cord injury.

If you think you have a UTI it is important to see your doctor. Your doctor can tell if you have a UTI with a urine test. Treatment is with antibiotics.
