2.10 Chronic paralysis virus

Chronic bee paralysis virus (CBPV) is a contagious disease that is transmitted mainly through direct contact and the exchange of food. Bees crowded tightly in the hive, prolonged periods of poor weather, long transports during migratory beekeeping, heavy forest nectar flows, and a high density of colonies in an environment with limited food supply appear to favour the occurrence of the disease. The virus can be fatal for infected adult bees. In general, only a few colonies are affected.
