The Rise of Cat Allergies: Causes and Management

The Rise of Cat Allergies: Causes and Management

A Surge in Cat Allergy Cases
As more households welcome cats as pets, the number of people suffering from cat allergies has also sharply increased. Symptoms often mimic those of a common cold, including sneezing, a runny nose, and in severe cases, difficulty breathing. Specifically, Fel d1, a protein found in cat dander, saliva, and urine, is the main trigger of allergic reactions in humans.

Symptoms and Causes of Cat Allergies
The most common symptoms of cat allergies include sneezing, a runny nose, nasal congestion, itchy or watery eyes, redness, and skin rashes. In severe cases, breathing difficulties and asthma attacks may occur. The protein Fel d1 is produced in a cat's skin and can become airborne, entering the human respiratory system or coming into contact with the skin, which triggers an allergic response.

The Growing Pet Ownership and Allergy Rates
Currently, around 6 million households in South Korea own pets, and the number of people living with pets is estimated to be about 15 million. It's known that about 15-30% of pet owners develop allergic reactions, with cat allergens being known to provoke stronger reactions than dog allergens—up to twice as much. Allergy-related conditions are especially common in younger populations, with 44% of patients under 19 years old and 27% of patients under the age of 5, according to recent medical data.

Managing Cat Allergies
The most effective way to manage cat allergies is by avoiding exposure to the allergen. This means minimizing contact with cats, using air purifiers, and wearing masks in cat-infested environments. In colder months, symptoms may worsen due to the lack of proper ventilation, as windows are kept shut and indoor air circulation is restricted.

Treatment for Cat Allergies
For those with severe symptoms, medications such as antihistamines and steroids can help alleviate discomfort. Additionally, immunotherapy, which involves gradual exposure to the allergen to build tolerance, is an option for those who wish to continue living with their cats while managing the allergy.

Diagnosis and Tests
If you experience persistent symptoms like sneezing or a runny nose after contact with a cat, it’s advisable to get an allergy test. Blood tests can measure the levels of antibodies against Fel d1, confirming the presence of a cat allergy.

The main symptoms of cat allergies include sneezing, a runny nose, nasal congestion, itchy or watery eyes, redness, and skin rashes. In severe cases, breathing difficulties and asthma attacks may occur.

2. What causes cat allergies?

Cat allergies are primarily caused by a protein called Fel d1, which is found in cat dander, saliva, and urine. This protein becomes airborne and can trigger allergic reactions when inhaled or when it contacts the skin.

3. How can I prevent cat allergies?

To prevent cat allergies, minimize contact with cats, use air purifiers, and wear masks in areas where cats are present. It’s also essential to ensure proper indoor ventilation, especially during the winter months.

4. How is cat allergy treated?

Severe cat allergies can be treated with antihistamines and steroids. Immunotherapy is also an option for those who want to continue living with their cats while reducing allergic reactions.

5. How can I get tested for a cat allergy?

Cat allergies can be diagnosed through a blood test, which measures the levels of antibodies against Fel d1 in your system.
