Preventing a Cold

Colds are extremely contagious. A cold is transmitted by droplets of fluid that contain the cold virus. These droplets become airborne when an infected person sneezes, coughs, or speaks. You contaminate yourself by inhaling these droplets or touching a surface that the viruses have landed on, and then touching your eyes or nose. To prevent getting a cold, take these simple precautions:

• Avoid close contact with people who have a cold.
• Wash your hands often.
• Do not touch your nose, eyes, or mouth. This will help you avoid infecting yourself with germs you may have picked up.

Avoid spreading your cold to others by:

• Covering your nose and mouth with a tissue when you cough or sneeze. Throw the tissue away. If you do not have a tissue handy then put your arm up over your face and sneeze into your elbow. Sneezing onto your hands increases your likelihood of spreading the cold to others.
• Wash your hands often.
• Limit close contact with others when you are sick.

Treating a Cold

Antibiotics will not cure a cold. In fact, nothing can cure a cold, except time. Certain self-care measures may help you reduce your discomfort. These include:

• Take certain over-the-counter (OTC) medications. For example, acetaminophen helps to relieve any aches and fever, while decongestants and antihistamines may combat congestion. Use caution, though, when giving these medications to children.
  • The US Food and Drug Administration (FDA) recommends that OTC cough and cold products should not be used to treat infants or children less than 2 years old and supports not using them in children less than 4 years old. Rare but serious side effects have been reported, including rapid heart rates, convulsions, decreased levels of consciousness, and death. OTC cough and cold products include decongestants, expectorants, antihistamines, and cough suppressants. The FDA is still reviewing data concerning the safety of these products in children aged 2-11 years. There have been serious side effects reported in this age group as well.
• Drink plenty of fluids every day. This will help keep you hydrated.
• Avoid alcohol as it promotes dehydration.
• Avoid smoke. It irritates an already sore throat and intensifies a cough.
• Get plenty of rest.
• Use a humidifier—An electric device that puts moisture into the air.

Preventing the Flu

A flu shot can lower your chance of getting the flu. You should get vaccinated during the fall and winter months, before the seasonal flu hits your area.

The US Centers for Disease Control and Prevention recommends that everyone over 6 months of age get vaccinated against the flu each year. Anyone who wants to reduce their risk of the flu should consider the vaccine.

Hand washing can also help prevent the flu, or any flu-like illness. Even if someone in your home has the flu, you can reduce your risk of getting sick by washing your hands. If soap and water are not available, hand sanitizers are also effective.

Treating the Flu

Most importantly, when you have the flu, you need rest. And until your symptoms are gone, it is a good idea to not go back to your full activity level. You also need plenty of fluids.

For most healthy people who come down with the flu, treatment with antiviral medications are not necessary. They may be recommended for people who have chronic health conditions, are severely ill, or have suppressed immune systems. Antiviral medications may help relieve symptoms and shorten the time you are sick. They must be taken within 72 hours of the first symptoms. Some kinds of seasonal influenza viruses are resistant to antiviral medications.

Antiviral medications include:

• Zanamivir—this drug may worsen asthma or chronic obstructive pulmonary disease (COPD)
• Oseltamivir
• Peramivir

Oseltamivir, and perhaps zanamivir, may increase the risk of self-injury and confusion shortly after taking, especially in children. Children should be closely monitored for signs of unusual behavior.

To relieve the aches and fever associated with the flu, you can try acetaminophen, found in over-the-counter medications such as Tylenol. For congestion, stuffy nose, and cough, you might want to try a combination of decongestant and antihistamine.
