Step-by-step explanation:
Risk factors associated with childhood asthma include previous respiratory or allergy problems, a family history of asthma, and exposure to pets, low birth weight, and late introduction of solid foods. Environmental factors such as pet dander, dust mite feces, and other allergens can trigger asthma attacks in individuals with a genetic predisposition to the disease. Additionally, certain viruses and bacteria contracted during infancy or early childhood may contribute to the development of asthma.
