in the United States has HIV, the virus
that causes AIDS.

Strains of HIV
HIV is a fast-mutating virus that has developed into many strains since
scientists first identified it in the United States almost 30 years ago.
There are so many strains of HIV that scientists haven't tried to count them all.
Simply put, there are 2 main types:
- HIV-1: most common type of HIV. Scientists believe it is responsible for
the global AIDS pandemic,
according to the National Institute of
Allergy and Infectious Diseases
-
HIV-2. : transmitted through bodily fluids, just as HIV-1.
- few cases of HIV-2 have been reported in the United States.
- The virus is most prevalent in parts of Africa, especially West Africa.
- less easily passed from person to person than HIV-1,
- generally takes longer for an infected person to develop illness from
HIV-2
What about Magic Johnson
• Magic Johnson discovered that he
was positive for HIV in 1991 .
• As of now, Magic Johnson's HIV
virus is at undetectable level. (he's
not virus free).
• Magic Johnson doesn't have AIDS.
Magic Johnson is not cured from
HIV
•
Magic Johnson still has HIV virus.
• virus was detected very early. And
he took very strong medication.
– With early detection & drug
treatment, a patient has 90% chance
of holding down HIV virus.
Prevention
Review:
- How is HIV spread?
- How can you protect yourself and others?

Sexual Risk Behavior: HIV
• Many young people engage in sexual risk behaviors that can
result in unintended health outcomes. For example, among
U.S. high school students surveyed in 20091
• 46% had sexual intercourse
• 34% had had sexual intercourse during the previous 3 months,
and, of these
– 39% did not use a condom the last time they had sex
• Sexual risk behaviors place adolescents at risk for HIV
infection, other sexually transmitted diseases (STDs), and
unintended pregnancy:
• An estimated 8,300 young people aged 13–24 years in the 40
states reporting to CDC had HIV infection in 20092
• Nearly half of the 19 million new STDs each year are among
young people aged 15–24 years3
Cure?
• What’s been done so far?
• Would Vaccine work?
• How would it work?
– mimics the structure of the “spike” (how the virus
copies itself from cell to cell) and attracts relevant
antibodies in the blood.
