What are bacteria and viruses?
Bacteria are single-celled organisms usually found all over the inside and
outside of our bodies, except in the blood and spinal fluid. Many bacteria
are not harmful. In fact, some are actually beneficial. However,
disease-causing bacteria trigger illnesses, such as strep throat and some
ear infections. Viruses are even smaller than bacteria. A virus cannot
survive outside the body's cells. It causes illnesses by invading healthy
cells and reproducing.
What kinds of
infections are caused by viruses and should not be treated with antibiotics?
How do I know
when an illness is caused by a viral or bacterial infection?
Sometimes it is very hard to tell. Consult with your doctor to be sure.
When do I
need to take antibiotics?
Antibiotics are very powerful medications. They should only be used when
prescribed by a doctor to treat bacterial infections.
Do I need an
antibiotic when mucus from the nose changes to yellow or green?
Yellow or green mucus does not indicate a bacterial infection. It is normal
for the mucus to get thick and change color during a viral cold.
Should I ask
my doctor to prescribe antibiotics?
Talk to your doctor about the best treatment. You should not expect to get a
prescription for antibiotics. If you have a viral infection, antibiotics
will not cure it, help you feel better, or prevent someone else from getting
your virus.
What is
antibiotic resistance and why should I be concerned?
Antibiotic resistance occurs when bacteria change in a way that reduces or
eliminates the effectiveness of antibiotics. These resistant bacteria
survive and multiply - causing more harm, such as a longer illness, more
doctor visits, and a need for more expensive and toxic antibiotics.
Resistant bacteria may even cause death.
What can I do
to avoid antibiotic-resistant infections?
Start by talking with your health care provider about antibiotic resistance.
-
Ask whether an antibiotic is likely
to be effective in treating your illness.
-
Do not demand an antibiotic when
your health care provider determines one is not appropriate.
-
Ask what else you can do to help
relieve your symptoms.
What can I do
to protect my child from antibiotic-resistant bacteria?
Use antibiotics only when your doctor has determined that they are likely to
be effective. Antibiotics will not cure most colds, coughs, sore throats, or
runny noses. Children fight off colds on their own.
If mucus from
the nose changes from clear to yellow or green, does this mean that my child
needs an antibiotic?
Yellow or green mucus does not mean that your child has a bacterial
infection. It is normal for the mucus to get thick and change color during a
viral cold.
Does this
mean that I should never give my child antibiotics?
Antibiotics are very powerful medicines and should only be used to treat
bacterial infections. If an antibiotic is prescribed, make sure you take the
entire course and never save the medication for later use.
How do I know
if my child has a viral or bacterial infection?
Ask your doctor. If you think that your child might need treatment, you
should contact your doctor. But remember, colds are caused by viruses and
should not be treated with antibiotics. |
