Ear infections are common issues that can affect anyone, particularly after a cold. A parent should suspect an ear infection if a child exhibits symptoms like fever, irritability, and ear pain. Although ear infections themselves are not contagious, the colds leading to them are, spreading through coughs and sneezes.

Normally, the eustachian tube maintains air pressure balance in the ears, but blockages can cause a plugged sensation and discomfort. Additionally, persistent dry coughs can have various causes, including ACE inhibitors for blood pressure control, as noted by Harvard Health.

Preventative measures like frequent handwashing, coughing into your elbow, avoiding sick individuals, and staying home when ill are crucial. Avoiding secondhand smoke can also reduce the risk of ear infections by preventing eustachian tube inflammation.

Some infections, like whooping cough, can cause a persistent cough and are preventable through immunization. It’s vital to recognize the signs of a respiratory tract infection, including increased mucus production and nasal congestion, as discussed by CHOP.

Occasionally, a cough may be the only symptom of post-nasal drip, which can be treated with antihistamine-decongestant medications. Adults typically experience coughs and colds a few times a year, with children having them more frequently. While not all cases require a doctor’s visit, persistent symptoms should be evaluated.
