A common cold is a viral infection of the upper respiratory tract, which includes the nose, throat, sinuses, and the upper part of the lungs. Its common symptoms include a runny nose, congestion, and a cough.

Caused by more than 200 viruses, adults get an average of two to four colds in a year, specifically between September to May. But despite being a typical human condition, how is the common cold affecting the human ears? Here are some ideas.

1. Antibiotic Resistance

With the common cold, antibiotics are not recommended as they do not fight viruses. There is no specific cure for it, as most cases get better after a few days. However, many patients still ask for antibiotics, leading to antibiotic resistance.

Antibiotic resistance is when bacteria become resistant to the drugs used to treat them. It means that the drugs are no longer effective against the bacteria, making it difficult to treat the infections they cause.

2. Ear Infections

Related to antibiotic resistance, ear infections are one of the most common reasons for antibiotic prescriptions in children and adults. However, most ear infections are caused by viruses and do not need antibiotics.

The good news is that most ear infections go away within a few days. But when they don’t, and a child or adult is in pain, people often turn to antibiotics. But the bad news is that ear infections become more resistant to antibiotics over time, making them difficult to cure.

3. Eardrum Scarring

The most severe complication of ear infections is eardrum scarring. Also called Tympanosclerosis,  it is a white lesion seen on or under the eardrum. In addition to causing hearing loss, scarring can lead to long-term problems with the middle ear.

In severe cases, people may need surgery to repair the eardrum. But even in mild cases, the damage caused by ear infections can lead to hearing problems later in life. However, fluoride treatments may reduce the severity of abnormal ringing or tinnitus.

4. Damaged Cilia

Cilia are tiny, hairlike structures in the inner ear that help protect it from bacteria and other harmful substances. However, ear infections can damage these cilia, leading to hearing loss. In some cases, the damage is permanent.

When the cilia are damaged, they can no longer move correctly and become entangled. As a result, it can lead to a build-up of earwax, which can further damage the cilia. In severe cases, the cilia may need to be surgically removed.

5. Hearing Loss

Ear infections can cause hearing loss in both children and adults. The hearing loss may be temporary or permanent, depending on the severity of the condition. In most cases, the hearing loss is temporary and will improve once the infection has cleared.

However, in some cases, the hearing loss may be permanent. Ear infections are a common cause of hearing loss in children. They are the most common cause of conductive hearing loss in children under three.


The common cold is one of the most widespread illnesses in the world. According to the Centers for Disease Control and Prevention (CDC), there are millions of cases of the common cold each year in the United States alone.

While the common cold is usually not a severe illness, it can lead to more serious health problems, such as pneumonia, bronchitis, and ear infections—one of the most common complications of the common cold.
