How do arthropods affect human health?

Arthropods can significantly impact human health through direct or accidental injury and bites. Many arthropods, such as mosquitoes, ticks, and certain spiders, can transmit diseases that pose serious health risks to humans. For instance, mosquitoes are known vectors for malaria, dengue fever, and Zika virus, while ticks can transmit Lyme disease and Rocky Mountain spotted fever. Additionally, some arthropods can inflict painful bites or stings that may result in allergic reactions or infections. Thus, the interaction between humans and these arthropods is a crucial health concern, emphasizing the importance of understanding their role in disease transmission and injury.

In contrast, while improving crop yield, promoting outdoor activities, and decomposing organic materials have positive effects on the environment and agriculture, they do not directly relate to the health impacts that arise from interactions with arthropods.
