What Do You Know About HIV/AIDS?

According to the CDC, more than 1.1 million Americans are infected with HIV, the virus that causes AIDS. Find out more about HIV and AIDS by taking this quiz, based on information from the CDC.

1. When was HIV first recognized in the United States?You didn't answer this question.You answered The correct answer is Around this time, doctors in Los Angeles and New York were reporting rare cases of pneumonia, cancer, and other illnesses among male patients who had sex with other men. These conditions were not normally found in people with healthy immune systems. It was several years before scientists developed a test for the virus.A. 1970B. 1975C. 1981D. 19862. Which of these is a symptom of HIV infection?You didn't answer this question.You answered The correct answer is Although these are symptoms of HIV, a blood test is the only way to know for sure if you have HIV infection. Symptoms are not always reliable. They can be mistaken for other illnesses. Severe symptoms like rapid weight loss or chronic infections usually do not appear for years, if at all. Even if you don’t have any symptoms, you can still infect other people. This is one important reason why early testing is so important.A. Swollen lymph nodesB. FeverC. TirednessD. All of the above3. A person is considered to have AIDS when which of these occurs?You didn't answer this question.You answered The correct answer is An HIV-infected person has AIDS when he or she has fewer than 200 CD4 cells. These cells are an important part of the body’s immune system and help to fight off infection. The definition of AIDS also includes developing one or more of 26 medical conditions, including opportunistic infections like recurrent pneumonia and Kaposi sarcoma (a cancerlike disease affecting the skin), even if that person doesn't meet the CD4+ criteria. Many of these conditions don’t affect healthy people, but someone with AIDS has little or no defense against infection because the immune system is too weak.A. Exposure to HIVB. HIV antibodies are detected in the bloodC. The CD4+ count is lower than 200 or opportunistic infections develop in an HIV-infected personD. A person has HIV for five years4. What does HIV-positive mean?You didn't answer this question.You answered The correct answer is When you are exposed to HIV, your immune system makes antibodies (a kind of protein) to fight that specific infection. These antibodies can be measured by a blood test. It usually takes two to eight weeks after infection before HIV antibodies can be detected. For some people, it may take longer, but most people will develop antibodies within the first three months after infection. Once the antibodies are detected, a person is considered HIV-positive. A person can also be diagnosed with HIV infection when a blood test detects the actual virus particles.A. Either antibodies against HIV or the virus particles themselves are present in the bloodB. You have been tested for HIVC. Your white cell count is highD. You have been informed about HIV5. HIV attacks a specific kind of cell in the immune system. Which is it?You didn't answer this question.You answered The correct answer is HIV targets a kind of white blood cell called a CD4 positive T cell, or T4 cell. This type of cell is a key immune response cell and fighter of infections.A. Red blood cellsB. White blood cells called T cellsC. PlateletsD. Epithelial cells6. What is the white cell count at which AIDS is considered to have developed?You didn't answer this question.You answered The correct answer is A normal count is 1,000 or more CD4 positive T cells per cubic milliliter. Below 200 per cubic milliliter means a person infected with HIV has developed AIDS.A. Below 1,000 per cubic milliliterB. Below 500 per cubic milliliterC. Below 200 per cubic milliliterD. Below 50 per cubic milliliter7. The risk for AIDS is attributed to behaviors. Which of these behaviors can put you at risk?You didn't answer this question.You answered The correct answer is HIV is found mostly in blood, semen, or vaginal fluid. An HIV-positive person can pass the virus through unprotected sex (oral, vaginal, or anal) and through sharing needles or syringes. Women can pass the virus to their babies before birth, during birth, or through breast-feeding. The risk of getting HIV from a blood transfusion is extremely low. Since 1985, all donated blood in the U.S. is tested. HIV is not spread through casual contact, such as shaking hands or hugging, or from sharing food, glasses, utensils, towels, bedding, toilet seats, or pets.A. Spending time with someone who has AIDSB. Not wearing latex condoms during sexC. Injecting drugsD. B and C8. Why is a combination of drugs-—called a cocktail-—used to treat HIV?You didn't answer this question.You answered The correct answer is The drugs are designed to attack the virus at different stages of its life cycle. When taken correctly, the cocktail overwhelms any chance of developing resistance to the drugs.A. The virus mutates rapidlyB. Each individual responds to each medication differentlyC. Combining medications triples their strengthD. A and B9. What is the best way to protect yourself against HIV?You didn't answer this question.You answered The correct answer is Currently, no vaccine is available for HIV. Protect yourself by abstaining from sex, by using a latex condom when you do have sex, and by not having any unprotected sex. Drug users must not share needles and syringes and should not expose themselves to the blood of others. Remember, a person can be HIV-positive and have no symptoms. Have yourself tested to learn your status. Oral contraceptives and spermicides don’t protect you from getting HIV.A. Get yourself vaccinated for HIVB. Use oral contraceptivesC. Use a latex condom during sexual intercourseD. B and CYour score was:
