How Many People Are Allergic to Pets?
1. 10%–20% of the world’s population is allergic to cats and dogs.
Pet allergies are common, especially to pets with fur and dander, but when the animal’s fur is not what triggers the allergy but the protein found in the pet’s dander. In the USA, up to 67% of households own a pet, but many of these owners will experience pet allergies, especially if they already suffer from allergies or asthma. Allergies to cats and dogs affect 10%–20 % of the world’s population.
2. Allergies are the fifth leading cause of chronic disease among Americans of all ages.
Allergies are the fifth leading cause of chronic disease among all ages in the United States, and asthma, which is often triggered by allergies, is the third most common chronic disease in children under eighteen.
3. Pet allergies affect 20% to 30% of asthmatics.
The most common type of asthma is allergic asthma. It is a respiratory condition triggered by pollen, mold, and dust mites. It causes the airways to narrow and mucous to build up, which makes breathing difficult. Pet allergies can trigger an asthma attack if a person suffers from asthma.
4. Some studies suggest that exposing young children to pet allergens during their first year may reduce their chances of developing allergies in general.
Some studies suggest that if children are exposed to pet allergens in their first year of life, it may reduce the likeliness of having allergies. The theory implies that the more exposure they have to pets, the more protection they will get. While research may claim that exposure to allergens may reduce the risk of asthma, there is still no guarantee that the baby will be free from allergies growing up.
Cat & Dog Allergies
5. In the United States, up to 30% of people are allergic to cats and dogs.
Up to 30% of US citizens are allergic to cats and dogs, and with 67% of homes in the USA owning a pet, which equates to about 84.9 million homes, that’s a lot of cats and dogs for allergy sufferers! Furthermore, even homes without pets can contain irritants; over 90% of residents test positive for allergens, even if they don’t share a home with an animal. This is because the allergens can easily spread and are challenging to eradicate once they have settled.
6. Cat allergies are more common than dog allergies.
Cat allergies are much more common than dog allergies. A similar protein is found in dogs’ dander, but the one in cat’s dander is one of the smallest molecules, measuring about one-tenth the size of a dust allergen. Because the allergens are microscopic, they stay in the air for longer and are easy to inhale.
7. 90% of children who have asthma also have allergies.
Cat allergies are the most common of all pet allergies. While allergies may not always cause asthma, 90% of children with asthma will experience allergies. Furthermore, studies show that up to 40% of children with asthma may develop allergy symptoms when exposed to cats.
Allergies to other Pets
8. Approximately one-third of people who come into contact with rodents will develop allergies to them.
Rodents have become a more popular household pet. Allergens from rats and mice come primarily from their urine, specifically the pheromones, which are proteins involved in communication. These proteins cause allergies in roughly one-third of people who come into contact with rodents.
9. It is estimated that 10%–15% of people are allergic to pet birds.
Pet birds can also be responsible for allergies and can be as much of a problem as cats and dogs for allergy sufferers. There are about 25–30 million pet birds in the USA, and approximately 10% to 15% of people can suffer allergies from the feathers of their pet birds.
10. Allergies can develop at almost any age, from infancy to adulthood.
Pet allergies can develop in any person of any age at any time. If you don’t currently suffer from allergies, that may change for you at any point. Allergies can also change over time; the symptoms may vary depending on how much and how frequently you are exposed and how sensitive you are.
11. Although pet allergies can develop, symptoms usually do not appear in children under the age of two.
Pet allergies can develop at any time in a person’s life, including in infants. Although pet allergies can develop, symptoms usually do not appear in children under two. Babies very often have runny noses and coughs, so it may be difficult to tell whether it is a common cold or allergies.
12. Exotic pet allergies have become more common in the last decade.
Exotic pets have become more popular, especially for those that live in small apartments that don’t have adequate space to own a dog or cat. People who are allergic to exotic pets will generally present the same symptoms as those from cats and dogs, which are usually respiratory-related. Because the occurrence of allergies to exotic pets is usually isolated, the incidence of allergies is unknown.
