传染病正在全世界回升。在讨论营养与传染病时，营养学家往往只考虑营养对宿主的影响。而最近的研究结果却提示，至少对于ＲＮＡ病毒来说，宿主的营养状况可影响这种病原体的遗传物质构成，从而改变其毒力。组织举办“新出现的病毒病：营养扮演什么角色”专题研讨会的目的是，提醒营养学界注意这一发现及其对营养－感染关系研究的可能意义。此次研讨会的专题有：病毒病对公共卫生的威胁、病毒ＲＮＡ基因组的迅速进化、氧化剂和抗氧化剂在病毒病中的作用——发病机制与代谢调节、维生素Ｅ缺乏或硒缺乏引起柯萨奇病毒Ｂ３毒力增加。如果有关柯萨奇病毒的研究结果可更广泛地适用于其它ＲＮＡ病毒，那么这些结果则可能具有很大的公共卫生意义，因为大部分动植物病毒和人类病毒都是ＲＮＡ病毒。
Infectious diseases are picking up worldwide. When discussing nutrition and infectious diseases, nutritionists often only consider the effects of nutrition on the host. Recent findings, however, suggest that, at least for RNA viruses, the nutritional status of the host can affect the genetic makeup of the pathogen, altering its virulence. The purpose of the symposium organized by the organization of The Emerging Virus Disease: What Role Does Nutrition Play To Remind the nutrition community to take note of this finding and its possible implications for the study of the relationship between nutrition and infection. The symposium featured topics such as the threat of viral diseases to public health, the rapid evolution of viral RNA genomes, the role of oxidants and antioxidants in viral diseases - pathogenesis and metabolic regulation, lack of vitamin E or selenium deficiency Odd virus B3 increased toxicity. If the results of the Coxsackievirus study are more broadly applicable to other RNA viruses, then these results can be of great public health significance since most animal and plant viruses and human viruses are RNA viruses.
