What are colds?

from The Better Health Channel

Colds (or upper respiratory tract infections) are the most common cause of illness in children and adults.

Most colds are caused by a virus. There are over 200 types of viruses that can cause the common cold, which is why it’s not possible to be immunised against a cold.

What causes colds?

Colds are more common in the winter months.

Cold weather by itself does not increase the chance of getting a cold. People are in closer contact with each other at this time of year, because they stay indoors, and so are more likely to infect each other.

The viruses that cause colds are spread by sneezing, coughing and hand contact.

Symptoms of colds

The symptoms of a cold include various combinations of:

a stuffy or runny nose
sneezing
sore throat
cough
headache
red eyes
swelling of lymph glands
fever (occasionally)
loss of appetite and, sometimes, nausea and vomiting.

The actual symptoms will vary from person to person and from illness to illness. Usually, the symptoms will last from a few days to a week or more, and you recover fully without any ongoing problems.

There is no cure, but symptoms can be relieved

There is no cure for the common cold. There is no specific treatment that will make the cold go away more quickly.Symptoms can be relieved in a number of ways:

Paracetamol can be given in appropriate doses if fever is present.
Drink plenty of fluids.
Nasal drops or spray will ease a blocked nose.
Throat lozenges.

Children with a cold don’t need bed rest

There is no need for bed rest if your child has a cold – let the child decide how much activity they want to take part in.

Although children are unlikely to be hungry, make sure they drink lots of fluids. Appetite will return as the child starts to feel better.

Don’t use medications

These treatments are not necessary and should be avoided:

Antibiotics – colds are caused by a virus and antibiotics will not help, even though they are often prescribed.
Cough medicines – these are of no benefit. The cough is caused by irritation of the trachea (windpipe) or excess mucus, and cough medicine does not affect either of these symptoms.
Cold remedies and tablets – preparations that can be bought over the counter at the chemist are usually not helpful and should be avoided.
Aspirin – do not give children aspirin as it may lead to a serious acute illness called Reye’s syndrome.

When to see the doctor

Virtually all upper respiratory tract infections get better without any specific treatment. See the doctor if you or your child:

refuses to drink fluids
vomits frequently
complains of intense headache
is pale and sleepy
has difficulty breathing
has a high fever that does not respond to paracetamol
shows no improvement in 48 hours
shows any other signs that you are worried about.

Prevention of colds

It is difficult to avoid getting upper respiratory infections. There is no value in taking vitamins in the mistaken belief that this will increase resistance.

There are some ways you can try to prevent getting a cold.

DO NOT GO TO WORK, CHILDCARE OR SCHOOL IF YOU ARE SICK!!

Wash your hands

Wash your hands regularly for at least 20 seconds, using soap and water or use a hand sanitiser that contains at least 60 percent alcohol.
Wash your hands when you get home, arrive at other people’s homes, at venues or at work.
Wash your hands after blowing your nose, coughing, sneezing, or using the toilet.
Watch this video about hand hygiene.

Don’t cough or sneeze into your hands

Cover your nose or mouth with a tissue, then throw it away and wash your hands.
If you don’t have a tissue, cough or sneeze into your elbow or upper sleeve.
Avoid touching your eyes, nose, and mouth with unwashed hands.

Other tips include:

Do not share drink bottles, glasses, crockery or cutlery other than with people you live with.
Keep your distance – stay 1.5 metres away from people where you can.
