Adults may catch a cold 2-3 times a year, while children catch it more often. Colds usually clear up after 7-10 days. If a cold lasts longer than this, it may be due to other health problems.
One of the first reasons to consider when a cold persists is contracting a new type of cold. Colds are caused by viruses. When you get sick, your immune system is activated to fight off the pathogens. But soon after, you can easily get another cold, but this time caused by a new type of cold virus, according to the health website Medical News Today (UK).
A persistent cough after a cold could be due to asthma or chronic obstructive pulmonary disease.
In addition, persistent cold symptoms can also be caused by the following health problems:
Side effects of the medication
Coughing is often the last symptom of a cold. However, if a cough persists, the cause may not be the cold but rather the effect of medication. In fact, a persistent dry cough is often a side effect of ACE inhibitors, such as lisinopril, benazepril, and ramipril.
The telltale sign of this condition is that, besides coughing, the patient will not have any other symptoms such as nasal congestion, sore throat, or sinus pressure.
Allergy
If a person continues to experience a runny nose and cough after 7-10 days of having a cold, the cause may be allergies. Depending on the time of year, allergy symptoms may last longer and be accompanied by itchy eyes and watery eyes.
Sinusitis
Sometimes, when cold symptoms begin to subside, symptoms such as sinus congestion, stuffy nose, headache, and fever reappear. This is because the cold causes a runny nose and nasal congestion, creating a favorable environment for bacteria to grow, leading to sinusitis. This usually occurs 10 to 14 days after the onset of the cold. Those affected need to be treated with medication.
Asthma hay
If more than 10 days have passed since a cold but the person still has a persistent cough and wheezing, it could be asthma or chronic obstructive pulmonary disease (COPD). Asthma is often detected early in childhood, while some cases are diagnosed in adulthood. COPD, on the other hand, is more common in older adults, especially smokers, according to Medical News Today.
