What health concern is associated with cockroach infestations?

Cockroach infestations are a significant health concern primarily due to their association with increased asthma severity. Cockroaches produce allergens that can trigger asthma attacks and exacerbate respiratory conditions in sensitive individuals, particularly children. Their droppings, saliva, and shed skin contain proteins that serve as potent allergens, which can become airborne and lead to respiratory issues upon inhalation.

While cockroaches can be vectors for various pathogens and can contribute to food-borne illnesses indirectly through contamination of surfaces and food, the direct impact of their allergens on asthma and allergy sufferers is a more critical health concern recognized by health professionals. This makes the connection between cockroaches and increased asthma severity a crucial aspect of understanding the health impacts of infestations.
