Ear infections
Meningitis
Pneumonia
Influenza Virus Flu
Illnesses caused by bacteria, viruses, fungi and parasites are called infectious diseases. Communicable diseases are illnesses that can be spread from one person to another. We commonly refer to communicable diseases as contagious.
Many illnesses are contagious before symptoms appear.
A communicable disease is disease that can be passed from one person to another. These diseases are often caused by germs, such as bacteria or viruses.

2. Some examples of contagious bacterial diseases are:
-strep throat
-impetigo
-pertussis (whooping cough)
-bacterial conjunctivitis (pink eye)
Antibiotics Work
Bacterial Infections
Are less common than viral infections.
Do not spread as easily from one person to another.
Cause infections such as pneumonia and strep throat.
Antibiotics work against most bacteria.

3. Some contagious viral infections include:
varicella (chicken pox)
rubella (German measles)
the common cold
hepatitis
mumps
infectious mononucleosis
rubeola (measles)
Antibiotics Don’t Work
Viral Infections
Are more contagious than bacterial infections.
If more than one person in your family has the same illness, it is most likely a viral infection.
Can make you just a sick as bacterial infections.
Usually get better in 7-10 days but it may take as long as three weeks to fully recover.
About 80% of all respiratory infections are viral.
Antibiotics do not work against viruses.

4. How are Bacteria and Viruses Different?
Let’s now take a look at some of the differences between bacterial and viral infections.
An important note about bacteria and viruses is that the diseases they cause can have the same symptoms, for instance cough or diarrhea, can be bacterial or viral. The treatment of each one will be different and how they are spread for person to person may be different.

5. Viruses
cause most common respiratory illnesses, such as colds and coughs
cause a variety of infections from diarrhea to meningitis
may take 2-3 weeks to resolve completely
some viruses can be prevented by vaccines and immunizations
antibiotics do not work for viruses
Viral Illness
Viruses are among the smallest microbes, much smaller even than bacteria. Viruses are not cells. Unlike most bacteria, most viruses do cause disease because they invade living, normal cells, such as those in the human body. They then multiply and produce other viruses like themselves. Viruses cause a variety of infectious diseases, among them the common cold, diarrhea, chicken pox, yellow fever, most childhood respiratory diseases and the majority of infections of the upper respiratory passages.
Antibiotics do not work against viruses.

6. ….viruses clear up on their own - antibiotics won't help!
Viruses Cause...
Most bronchitis/chest colds
Green/yellow nasal discharge
Flu
Most sore throats
Ear aches and some sinusitis
There are two main causes of respiratory infections: viruses and bacteria.
Viruses cause colds, flu, bronchitis/cough, and most sore throats. More than 80% of sore throats are caused by viruses.
Did you know that bronchitis is another word for cough illness?
….viruses clear up on their own - antibiotics won't help!

7. Bacteria
make you sick when they are where they don’t belong or grow more rapidly than normal
live in your mouth, nose and throat
are necessary for normal body functions like digestion
are one of the oldest living things on Earth
Bacterial Illness
Bacteria are minute life forms made up of only one cell which can cause infections in humans. Life in any form on Earth could not exist without these tiny cells. Bacteria have the ability to adapt quickly to their surroundings. Their goal is to survive and multiply. This ability to adapt to their surroundings is the basis of antibiotic resistance. Surviving contact with antibiotics allows the bacteria to resist the antibiotic the next time it is used.
Antibiotics work against most bacteria.

8. Bacteria Cause... Strep throat Some ear infections
Some sinus infections
Pneumonia
...these can be treated with antibiotics
Bacteria is the second main cause of respiratory infections. They cause strep throat and some ear infections.
Ear infections and sinus infections can be caused by either a virus or a bacteria. If a virus is the cause, antibiotics will not work.
Many ear infections and sinus infections will clear up on their own. A doctor may wait to prescribe an antibiotic. It’s important to work with your doctor to monitor your symptoms so that your doctor can make the best decision about whether an antibiotic is needed or not.

9. What are Antibiotics?
Powerful medicines with one very important job: to fight disease-causing bacteria.
When used properly, antibiotics can save lives.
Let’s start by understanding what antibiotics can do. Review slide. 5

10. Antibiotic Resistant Bacteria Are:
Bacteria that mutate and are able to resist the antibiotics that are meant to kill them.
This is a normal process speeded up by the overuse and misuse of antibiotics.
Bacteria are very clever and very easily adapt to their environment. Many bacteria have already adapted to resist antibiotics. This means the antibiotic will no longer be able to kill the bacteria that causes the illness. These bacteria are called antibiotic resistant bacteria.
We all have bacteria living in our bodies called normal flora. When you take an antibiotic for a viral infection, these normal bacteria are being overexposed to antibiotics and can become resistant. Also, if you don’t finish the medication some bacteria remain and develop resistance to the medication, they then can continue to grow and mutate. 8

11. What is Antibiotic Misuse?
Taking antibiotics when they are not needed:
for viral infections
When needed, taking antibiotics incorrectly:
stopping the medicine when you feel better - not finishing the prescription
saving antibiotics for a future illness
sharing or using someone else’s medicine 6

12. Why do young children have more illness?
Anyone at any age can be infected with a communicable disease, but young children are at greater risk because:
They have not been exposed to many of the most common germs and have no immunity to these illnesses.
They have many habits which promote the spread of disease.

13. The germs that cause infectious diseases may be spread from person to person by indirect contact with objects or materials that are contaminated, such as, clothing, bedding or eating utensils.
Young children are especially likely to share personal items. This increases the chances of spreading germs.
Infection can result from sharing towels, dishes, or from handling contaminated objects. Indirect contact or skin to skin contact can also result in the spread of an illness.

14. Sometimes an illness is passed to others by a carrier, or a person who has been infected by a germ but does not look or feel sick. This person may carry the germ in their nose, throat, or stomach. They can pass the germ to others by coughing, sneezing, or by not washing their hands properly.
Many respiratory illnesses are spread through the inhalation of germs in the air and direct contact with infected saliva or mucus.

15. Light patches indicate germs carried on the hands
Your hands carry many germs even if you can’t see them.
Many people don’t wash their hands because they look clean.
As you can see this is not always the case.
Illness is also spread through body fluids, blood and and hands contaminated with fecal matter or saliva and nasal discharge.
Behaviors that promote the spread of disease in this way are not washing hands after toileting or blowing your nose. Infection can result from touching someone’s hand after they have used their hand to cover a sneeze.
Light patches indicate germs carried on the hands

16. Why is Antibiotic Misuse a Problem?
Antibiotics become less effective and may not work the next time you use them.
Improper use of antibiotics leads to more antibiotic resistant bacteria.
Antibiotic resistant bacteria can be spread throughout the community and from person to person.
The usefulness of antibiotics is slowly being eroded by misuse. Already there are bacteria which are completely resistant to the penicillin group of drugs.
As resistant bacteria spread, treating minor bacterial illnesses can take longer and require medicines that have more side-effects and take longer to work.
The consequences of using antibiotics inappropriately affect everyone. 7

17. Antibiotic Resistant Bacteria
Require stronger antibiotics
Are more common in people who recently used antibiotics*
Can be spread within a family or a community
Can affect anyone
Are becoming more common

18. Myths & Facts about Antibiotics and Respiratory Illness21

19. Myths and Facts
Myth: Taking antibiotics means I or my child can return to work or childcare sooner
Fact: Antibiotics do not shorten the duration of viral illnesses
Everyone should stay home until they are fever-free and well enough to participate in activities whether they have a viral or bacterial illness. 22

20. Myths and Facts
Myth: Cold and flu symptoms will feel better or get better faster on antibiotics
Fact: Antibiotics cannot ease the symptoms of viral illnesses; these infections resolve on their own
Children and adults need extra rest and care, extra fluids…not antibiotics, symptomatic relief is helpful 23

21. Myths and Facts
Myth: Illnesses with the same symptoms require antibiotics
Fact: Illnesses with similar symptoms can be caused by different germs
Let a healthcare provider decide if the illness is caused by a virus or bacteria - and if antibiotics are needed 24

22. Myths and Facts
Myth: If I take an antibiotic, I won’t spread my illness to others
Fact: Viral illnesses (colds, flu, etc.) usually spread from person to person before the onset of symptoms; before a person appears ill
Antibiotics cannot stop the spread of viral illnesses 25

23. How do we Stop Antibiotic Misuse?
Don’t ask for antibiotics – let your doctor decide if you need them
Always take antibiotics exactly as prescribed
Finish the whole prescription - do not stop when you feel better
Never save antibiotics for a future illness – or share with others
Each one of us has a role to play in protecting the usefulness of antibiotics. We have a tendency to take antibiotics for granted, but here are some simple measures you can use to protect yourself and your community. 10

24. How Can You Keep Yourself Well
Handwashing
Immunizations
These two things will to reduce the chance of becoming sick. 29

25. Wash Your Hands... 30 Upon arrival to and before leaving work
Before and after handling food
Before and after toileting
After:
working outside
handling pets
handling any body fluids
wiping a child's nose or your own
using play dough, sand or water tables 30

26. Hand Washing is Important Because…
80% of disease is spread by your hands.
Hand washing is the most effective way to prevent the spread of respiratory illness.
Some germs can live on dry surfaces for several hours and moist surfaces like, sinks for 3 days.

27. Handwashing Guidelines
Wet hands with warm, running water
Add soap (preferably liquid), rub hands together to make a lather, away from water, for at least 15 seconds
Rinse hands well
Dry thoroughly with a clean, disposable towel
Use a hand sanitizer (alcohol-based) when soap and running water is not available (when outside or on trips, wash hands upon return from trips) 32

28. Despite Good Handwashing,
Children and adults will still get sick... 33

29. Immunizations
Immunizations are another important part of infection control for vaccine preventable disease
Make sure you and your family is up-to-date on immunizations
Get an annual flu shot 34

30. Take Home Messages Viruses cause most common respiratory illnesses
Viral illness needs time to heal - antibiotics cannot help
Antibiotics do not work against viruses. 35

31. Take Home Messages 36 Taking antibiotics for viral illnesses will not:
cure the infection
keep others from getting the illness
make you feel better
Antibiotic resistant infections are more serious and harder to treat!
People who take antibiotics frequently are more likely to have resistant bacteria and to be infected with resistant bacteria.
But it will make it more likely you will have resistant bacteria in your body. 36

32. Bottom Line
Antibiotics are powerful medicines, but they're not always the answer!
Misusing antibiotics now means they may not work when needed later to fight a bacterial infection
We all need to play a role to help keep antibiotics working!
