Individuals affected by the common cold may experience sneezing, a stuffy nose, cough and a sore throat. Symptoms of a cold may appear two or three days after infection and can last for two to 14 days. The common cold rarely leads to serious complications, but it can dangerously aggravate existing conditions.
Ear Infections
The common cold may lead to ear infections in children by obstructing the tube leading into the middle ear. The space behind the eardrum can be infiltrated by a virus or bacteria, which then causes the infection. Earaches, green or yellow nasal drainage and the recurrence of a fever are symptoms associated with an ear infection following a cold. Children unable to verbalize may show signs of an ear infection via discontentment. Crying or difficulty sleeping may be observed. Ear pulling may be present, but this is not always a reliable sign for an infection.
Sinusitis
A common cold can lead to sinusitis, which is an infection and inflammation of the sinuses. The sinuses are air-spaced cavities in the skull. Sinusitis following a cold is usually mild but can become more serious. Antibiotics generally eliminate the infection.
Aggravation of Asthma
The common cold can aggravate asthma in children and adults. The airways may become inflamed, which can increase in intensity throughout the duration of the illness. Wheezing can also be provoked in asthma sufferers.
Other Secondary Infections
Secondary infections are other illnesses that often result from an initial infection. The common cold is dangerous for adults and children with a weakened immune system as their susceptibility for acquiring a secondary infection is greater. Hospitalized and nursing home patients may be more vulnerable to lower respiratory tract infections such as pneumonia and bronchitis. These illnesses are the result of a secondary infection from the common cold. Strep throat might follow a cold too. Croup can develop in children from a previous cold infection. Secondary infections that develop as a result of the common cold need to be treated by a doctor.
