1. Infectious Diseases

2. Infectious Diseases - A disease caused by an agent that can pass from one living thing to another
Communicable disease – an infectious disease that is passed from one person to another.

3. What causes Inf.Dis.
Bacteria - a type of microorganism that can cause disease.
Strep throat, food poisoning, urinary tract infections.
Viruses – a type of agent that can cause disease.
Cold, flu, cold sores, measles, mono.

4. How are they spread
Air
Contact with contaminated objects
Person to person
Animals that spread disease
Food and water

5. Defenses against infection
Skin
Chemical warfare on germs (sweat and oils produce acids that kill bacterial)
Mucus membranes
Stomach acids
Helpful microorganisms
Inflammations
The immune system

6. Weapons T-cells – cells that regulate the action of the immune system
Antibodies – substances that stick to the surface of pathogens slowing their action.
B-cells – cells in the immune system that produce antibodies against infection

7. Immunization – injection of a small amount of a pathogen that will provide protection against an infectious disease.
Antibiotics – drugs that kill or limit the growth of bacteria.

8. HIV

9. H – Human: virus can only infect humans
I – Immuno-deficiency: the effect of the virus is to create a deficiency, a failure to work properly with the body’s immune system.
V – Virus: one of its characteristics is that it is incapable reproducing by itself. It reproduces by taking over the machinery of the human cell

10. How is HIV spread Bodily Fluids Blood Semen Vaginal secretions
Breast milk

11. Sexual Contact
Sexual intercourse
Oral sex
Anal sex

12. Blood to Blood Contact Sharing needles or syringes
Tattooing - Piercing
Accidental needle stick in a medical setting

13. Incidental Cases Mother to baby during pregnancy and delivery
Mother’s milk to baby
During Dental Procedures

14. The following body fluids are NOT infectious
Saliva
Tears
Sweat
Feces
Urine

15. Signs and symptoms HIV There are no true signs of having HIV.
One may experience flu – like symptoms of chills, fever, night sweats, rashes, etc.
Some will have no signs or symptoms.

16. How HIV Works HIV gets into the bloodstream
HIV targets white blood cells (T4 cells)
Virus slowly destroys T4 cells
Forces T4 cells to make copies of HIV
Eventually the cell dies
Moves on to other T4 cells
Can be up to 10 years before person shows signs

17. Phases of HIV infection
Infection with no signs or symptoms HIV – does not mean AIDS
Signs and symptoms
AIDS – T4 cells are less than 200 cells per microliter of blood or serious conditions from long-term, damage to immune system
Opportunistic Infections

18. Testing
ELISA – blood test that identifies whether a person has antibodies for HIV
Western Blot Test – done to confirm the results of the Elisa test.
Incubation Window – it can take 6 wks to 6 mths for anti. to form after exposure to HIV. This test should be done at least 6 wks after a person is or thinks they are infected.

19. AIDS

20. A – Acquired: a condition one must acquire or get infected with.
I – Immune: it affects the body’s immune system, the part of the body which usually works to fight off germs such as bacteria and viruses.
D – Deficiency: makes it not work properly
S – Syndrome: a group of symptoms

21. Signs and symptoms of AIDS
There are no common signs or symptoms for AIDS
People may experience opportunistic infections – when the immune system is weakened and can attack the body.
EX.- pneumonia.

22. AIDS is not spread by:
Casual contact – dry mouth kissing, hugging, being sneezed on or coughed on.
Mosquito bites

23. How to Protect yourself
Abstinence %
Have Safe Sex - Practice Monogamy – (when two people have intercourse with only each other for their entire lives).
Don’t use dirty needles
Get tested

24. Now that we have covered HIV and AIDS, What is the difference in them
Now that we have covered HIV and AIDS, What is the difference in them? Are they the same thing? Why do these two things always get linked together? Is one more dangerous then the other?

25. Sexually Transmitted Disease
STD Facts
Sexually Transmitted Disease

26. What is an STD?

27. How is STD Spread
STD is spread during close, sexual activity. It is spread during vaginal, anal and oral sex.

28. Most STD germs need to live in warm, moist areas
