Here is the next post in the series I did for A Musing Maralee’s blog. I answer some of her reader questions concerning the common cold and influenza infections. You can find the original blog post here.
What is the biggest mistake you see parents making in treating the common cold or flu?
If a child has a cold, when would it be necessary to see a doctor? If they have the flu, when would it be necessary?
What are the pros and cons of cold medicine for children?
The common cold and influenza are both caused by viral infections of the respiratory tract. That’s about where the similarities end. The common cold is caused by over 200 different strains of viruses while influenza only has a couple predominant strains each year. The common cold causes a runny nose, congestion, a sore throat, cough, and often a mild fever. Influenza on the other hand can be devastating. It causes a violent infection of the upper respiratory tract (the nose and throat) as well as usually infecting the lower respiratory tract (the trachea, bronchi, and lungs). Fevers up to 104F are typical. The common cold hits its stride during the fall and winter months but can be a problem all year long. Influenza tends to come in mini-epidemics for individual communities. January through mid February is the peak season for my town.
The biggest mistake I see parents making in treating the common cold or influenza is seeking medical care at the wrong time. For most of the year when a child gets a fever and has a runny nose or sore throat that’s just a symptom of the common cold. A lot of TLC and chicken noodle soup will help them along until the body clears that infection in about 7-10 days. No amount of medication will change that time frame. If the common cold infection causes enough disruption in the body’s normal defenses, bacteria that are always around trying to invade will take the opportunity to set up shop. A new fever, new pain, and focusing of symptoms to the affected spot would be an indication that something different is occurring. This could be fluid build up in the middle ears, the sinuses, and even just the nose. Bacteria grow and cause an ear infection, a sinusitis, or a rhinitis. Medical attention would be a good idea at that time.
During influenza season a new pronounced fever (>102F) especially if there is a known exposure should prompt an evaluation right away. After about 48-72 hours of symptoms antiviral medications that help limit influenza’s spread don’t work. The person just has to ride it out at that point which is often a two week process.
