1. Lyme disease caused by the bacterium Borrelia burgdorferi
Vector-Borne Transmission by tick bites
Symptoms: fever, headache, fatigue, and a characteristic skin rash
treated successfully with a few weeks of antibiotics.
Steps to prevent Lyme disease include using insect repellent & removing ticks promptly,

2. Microbes, disease transmission, and STD‘s
STD = sexually transmitted disease

3. Statistics
There are almost 9 million new cases each year of STDs among people aged 15–24 years (Sexual Risk Behavior: HIV, STD, & Teen Pregnancy Prevention)
A new study by John Douglas, director of the Center for Disease Control, finds that one out of every four sexually active girls between the ages of 14 and 19 in the United States has a sexually transmitted disease. (Previous Conferences – 2008)

5. Herpes Simplex Virus HSV1 & HSV2 Transmission
Direct Contact: Genital herpes is transmitted through direct skin-to-skin contact during vaginal, anal, and oral sex. Oral herpes is most often contracted through kissing someone with a cold sore.
Herpes can be transmitted even with no symptoms present.
40 million teens aged were reported to be infected in 2003 (Looker, 2008)
Under a microscope, HSV- 1 and 2 are virtually identical, sharing approximately 50% of their DNA.
Both types infect mouth or genitals
For both types, at least two-thirds of infected people have no symptoms, or symptoms too mild to notice.
both types can recur and spread even when no symptoms are present.
HSV-1 usually produces sores around the lip or face. HSV-2 usually produces sores in the genital area.
Herpes Simplex Virus

6. HEPATITIS A Virus (HAV)
Prevention & Treatment
Common Transmission
Virus is spread from contaminated fecal material
Food Borne: Ingestion of fecal matter, even in microscopic amounts, from ingestion of contaminated food or drinks.
The virus can last in the environment for extended periods.
Viral infection of the liver
A vaccine is available
Always wash hands after using the toilet
Most infections are gone within a few weeks
HEPATITIS A Virus (HAV)

7. HEPATITIS B Virus (HBV)
Prevention & Treatment
Transmission
Direct Contact: through contact with the blood or other body fluids of an infected person primarily through sexual contact.
50 to 100 times more infectious than HIV (Hepatitis B, 2012)
2 billion people worldwide have been infected
Viral infection of the liver
A vaccine is available
No treatment but may eventually be defeated by own immune system
HEPATITIS B Virus (HBV)

8. Human Papillomavirus (HPV)
Transmission
(Human Papillomavirus, 2010)
Prevention & Treatment
There are more than 40 HPV types
There is no way to know which people who get HPV will go on to develop cancer.
condoms may lower the risk of transmission
Vaccines can protect males and females against some of the most common types of HPV.
Direct Contact: Genital/sexual contact with an infected person
At least 50% of sexually active people will have genital HPV at some time in their lives.
99% of all cervical cancer cases are linked to genital infection with HPV
Human Papillomavirus (HPV)

9. SYPHILIS Bacterial infection
Prevention & Treatment
Transmission
Bacterial infection
Direct Contact: transmitted through sex and open sores of infected person.
Antibiotics
There are about 40,000 new cases of syphilis reported each year. (Syphilis Statistics )
SYPHILIS

10. GONORRHEA also known as Clap, Dose, Drip
Transmission
Prevention & Treatment
also known as Clap, Dose, Drip
Infection caused by gonococcus bacteria  
Direct Contact: most often through sexual intercourse with an infected person. 
CDC estimates that, annually, more than 700,000 people in the United States get new gonorrhea infections (Gonorrhea - CDC Fact Sheet)
Treated with antibiotics although a new strain of antibiotic resistant have been found.
Use a condom when you have sex
GONORRHEA

11. HIV: Human Immunodeficiency Virus
HIV: Human Immunodeficiency Virus

12. HIV: Human Immunodeficiency Virus
Transmission
Prevention & Treatment
weakens the immune system, making it harder to fight off infections.
Direct Contact: Transmitted through sex with an infected person,
Indirect Contact: sharing needles with an infected person
HIV is not transmitted by saliva, toilet seats, sharing towels, or shaking hands.
Currently there is no vaccine to prevent HIV or a treatment that cures HIV.
Used in combination with one another, powerful antiretroviral medications can slow down the virus and the progression between HIV infection and the development of AIDS.
