An itchy nose is often mistaken for a sign of a common cold, yet this complaint can also arise from allergic rhinitis. Although they have similar symptoms such as sneezing and a runny nose, these two conditions have different causes and treatment approaches.
Allergic rhinitis occurs due to an immune system reaction to allergens, such as dust, mites, animal fur, fungi, or pollen. Infectious colds are generally caused by viruses that attack the respiratory tract, including rhinovirus which is the most common cause of mild flu.
In allergic rhinitis, nasal itching typically appears after exposure to an allergen because the body produces an immune response to a harmless allergen. Characteristic symptoms include itching, sneezing, and a runny nose, usually without fever. Symptoms often appear in specific environments, such as dusty rooms or near pets.
A cold due to infection occurs when a virus enters the body. Symptoms typically appear gradually and improve on their own within several days to one or two weeks, although the duration can vary depending on the person's condition and the type of virus causing it.
The main difference lies in the cause and duration. Symptoms of allergic rhinitis can last longer or recur as long as the person is exposed to the allergen, while infectious colds usually improve after the body fights off the virus. Fever is more commonly associated with infection than allergy. Allergic rhinitis can flare up when exposed to dust, smoke, or other allergens, while infectious colds can spread through close contact with a sick person.
For allergic rhinitis, the main step is to avoid allergens by cleaning the house of dust, washing bedding regularly, and reducing exposure to smoke or other allergens. A doctor can also recommend medications such as antihistamines or nasal sprays according to the patient's condition.
For infectious colds, treatment focuses on relieving symptoms through adequate rest, maintaining fluid intake, and practising good hand hygiene to aid the recovery process. Antibiotics are not needed for colds caused by viruses because these medications do not work against viral infections.
Nasal itching should be examined by a healthcare professional if it lasts a long time, worsens, interferes with daily activities, is accompanied by shortness of breath, high fever, facial pain, or nasal discharge that does not improve. By recognising the differences between allergic rhinitis and infectious colds, a person can determine the most appropriate treatment steps based on the cause.
