What defines deformed wing virus (DWV)?

Deformed wing virus (DWV) is defined as a viral infection that specifically affects honey bees. It is an RNA virus, which means its genetic material consists of ribonucleic acid. This virus is particularly harmful as it can lead to significant deformities in adult bees, most notably deformed wings, reducing their ability to fly and perform essential tasks within the colony.

Understanding the nature of DWV as a viral infection is crucial, as it differs fundamentally from diseases caused by fungi, bacteria, or other pathogens. For example, fungal diseases often affect the organism in a different manner or focus on specific types of infections that do not involve the type of deformities or symptoms associated with DWV. Similarly, DWV is not associated with sac brood, which is a separate viral disease that affects bee larvae, highlighting the importance of accurately distinguishing between different types of bee diseases and their causes.
