可传播的病原体是群居动物的祸害，因此它们进化出了行为来降低感染的可能性。然而，没有记录表明群居动物在野外躲避自己物种的患病个体。在这里，我们展示了健康的、通常群居的加勒比海刺龙虾(Panulirus Argus)如何避免感染致命病毒的同种异种。健康的龙虾及早发现和避免被感染的个体，虽然还不具传染性，但具有选择性优势，并突显了宿主行为在自然种群中疾病传播中的重要性。
Transmissible pathogens are the bane of social animals, so they have evolved behaviours to decrease the probability of infection,. There is no record, however, of social animals avoiding diseased individuals of their own species in the wild. Here we show how healthy, normally gregarious Caribbean spiny lobsters (Panulirus argus) avoid conspecifics that are infected with a lethal virus. Early detection and avoidance of infected, though not yet infectious, individuals by healthy lobsters confers a selective advantage and highlights the importance of host behaviour in disease transmission among natural populations.
