Outcomes
  • What youll learn from this presentation
  • Differences between bugs, germs, bacteria, and
    viruses
  • Why these guys can cause trouble
  • What we can do to protect ourselves

4
What are we really talking about?
  • Germs?
  • Bugs?
  • Bacteria?
  • Viruses?

5
Germs and Bugs
  • In every day use, we might say I picked up a
    bug
  • What is a bug?
  • 1) Something small that is making us sick.
  • 2) Something we catch from someone else or from
    something like food that has gone bad.

6
Germs and Bugs (2)
  • Germs and bugs are not accurate words to use
    professionally in the health field
  • But after giving you a formal definition of
    bacteria and viruses, which are the more correct
    names for germs, we will go back to using bugs
    and germs

7
Bacteria
  • Technical Definition
  • Any of a variety of one-celled micro-organisms
    of the plant kingdom, existing as free living
    organisms or parasites, multiplying by
    subdivision and having a large range or
    biochemical (including pathogenic) properties.
  • Melloni Medical Dictionary

8
More about Bacteria
  • Can exist almost anywhere
  • More bacteria as separate individuals than any
    other organism
  • More useful types than harmful ones
  • Used in many human tasks making alcohol,
    cheese, sewage disposal

9
Viruses
  • Technical Definition
  • An intracellular, infectious parasite, capable
    of living and reproducing only in living cells.
  • Melloni Medical Dictionary

10
More about Viruses
  • They are very tiny and require an electron
    microscope to be seen
  • Are composed of mainly nucleic acid within a
    protein coat
  • At this time, viruses are not known to be of
    value to man, but as we have been able to work
    with them for only about 80 years, we still have
    a lot to learn about them.

11
Germs and Bugs Problems (1)
  • Germs cause infectious diseases.
  • Infectious diseases are a major problem in many
    parts of the world, especially poorer countries.
  • TB, malaria, diarrhea, measles and HIV/AIDS are
    some of the major infectious diseases that are
    caused by germs.

12
Germs and Bugs Problems (2)
  • Being sick with an infectious disease is a
    problem not just for the individual but for the
    persons family, the persons village and the
    whole community.
  • If youre sick, you cant work you cant harvest
    the crops.
  • If youre sick, you can infect other people and
    so on and so on.

13
The Major Infection That Were Worried About
  • We lived with Malaria and TB and we know that
    they take a long time to kill us!
  • Avian Flu or Pandemic Flu can kill many people,
    very fast.
  • These flus are spread by germs

14
Protection Against Bugs and Germs
  • The first thing to do is to ask how bugs and
    germs grow and then how they spread among people
    and also among animals as they can also be
    affected by bugs and germs

15
How Bugs and Germs Grow
  • Think of what we need to live and increase in
    numbers
  • A good safe place
  • A good food source
  • No enemies

16
Good Places for Bugs to Grow
  • Each type of bug can be different but for most
    them warmth and moisture are important.
  • Food should be readily available.
  • If no enemies they can multiple very fast.
  • The inside of bodies is often an excellent place
    with everything that a bug needs!

17
How Bugs and Germs Spread
  • 1. They often can move a little bit where they
    are living but cant make big moves.
  • 2. They need a carrier
  • people
  • pets
  • animals
  • insects
  • plants

18
Using People
  • What did we do at the beginning of the class?
  • Did anyone share my food and drink?
  • Did anyone cough or sneeze?

19
Using Pets
  • My dog likes me to scratch his ears and is always
    hanging around the kitchen and the table..
  • When I take my dog for a walkyes! If I dont
    pick it up there are a lot of germs in that mess
    waiting for a ride
  • Dogs and cats can drool on furniture and lick our
    hands.

20
Using Animals
  • Just like my dog, many animals live near people
    and their poop has germs.
  • People who work with the skins (or feathers) of
    wild or domestic animals can pick up germs from
    the skins (or feathers).
  • Animals can get sick from their own diseases and
    die. Their carcasses can be full of germs
    waiting to be picked up.

21
Using Insects
  • Flies are everywhere. Just think where was that
    fly walking before it walked on your food?
  • Mosquitoes spread many germs that cause major
    diseases.
  • Ticks and other insects feed on our blood and
    spread germs in the process.

22
Using Plants
  • If you eat a vegetable or a fruit ask yourself
    how it got water?
  • Who picked the plant?
  • Who prepared it for the table?

23
Protecting Ourselves
  • Basic Principle
  • Cut the spread of germs.
  • If they cant spread and multiple, they will die
    off.

24
Protecting Ourselves from Bugs and Germs
  • 1. Avoid problem areas and sick people
  • 2. Long lasting protection, such as vaccinations
    and immunizations shots
  • 3. Short lasting protection, such as bug spray

25
More Protection
  • The basics Soap and Water!
  • Washing hands Happy Birthday x 2
  • Washing our bodies
  • Washing our fresh fruits and vegetables
  • Washing clothes
  • Washing places in our homes

26
More Protection
  • For airborne spread
  • Cover mouth when coughing or sneezing
  • Wearing a mask
  • when dealing with items that have bugs and germs
  • when other people are coughing and sneezing

27
More Protection
  • To reduce germs around our houses
  • pick up poop
  • get rid of things that can hold still water
  • get rid of rotten old food

28
Avian Flu How Its Spread Among Birds
  1. Normal spread is from a wild bird to domestic
    bird.
  2. Ducks, geese and swans are usual carriers.
  3. Can be spread among domestic birds by
    contaminated food and clothing, feed and cages.
  4. The current highly lethal virus HPAI H5N1 can
    survive for 35 days in contaminated poop at 4C
    and for 6 days at 37C.

29
Spread from Birds to Humans
  1. Still unclear how its spread but mainly through
    contact with dead or sick birds especially when
    slaughtering birds.
  2. Bird droppings can be a source of infection in
    areas where kids might play.
  3. It does NOT appear to spread by eating thoroughly
    cooked meat.

30
Why Avoid an Avian Flu Death?
  1. H5N1 at the moment is highly lethal.
  2. Death is relatively rapid.
  3. Acute respiratory distress within around 6 days
    of infection you need to be intubated in order
    to breathe.
  4. Multi-organ failure and breakdown
  5. All the health staff will be wearing protective
    clothing no human contact.

31
Can We Prevent Avian Flu Spread
  • Only way to successfully stop the spread is by
    slaughtering and carefully disposing the bodies
    of all the birds
  • Rigorous disinfecting of the farms and areas
    where the birds were
  • How could this be done in the Islands?

32
Are There Any Drugs to Prevent or Cure?
  1. A number of firms are working on a vaccine
    against the H5N1 strain
  2. Tamiflu CAN be useful if given to the patient
    within 48-60hrs after symptoms begin

33
Current Situation
  1. 231 deaths since the beginning of the latest
    outbreak beginning December 2004
  2. Most deaths have occurred in S.E.Asia but there
    have been deaths in Turkey.
  3. The disease has been detected in birds all over
    Europe and Asia
  4. WHO is paying very close attention to the problem
    as are most countries in the whole world because
    the costs of a pandemic would be very high

34
If There is an Outbreak of Pandemic Flu What
happens?
  • To date the most talked about solution is social
    isolation for two weeks.
  • However
  • 1. Wed still need to clean up the virus
  • 2. How would your community cope with no
    one working for 2 weeks?????

35
Best Advice
  • Keep yourself up-to-date on what is happening
  • Practice the basic steps!
