Final answer:
The statement that there have been no associations with the virome and human disease is false. Viruses have been extensively linked to human diseases, and their classification often begins with characteristics like the presence of an envelope and virion shape. The potential for new and more deadly viruses to emerge also underscores the ongoing risk posed by the virome.
Step-by-step explanation:
The assertion that there have been no associations with the virome and human disease is false. Multiple studies and historical evidence show that viruses have been closely linked to a range of diseases in humans. From well-known diseases like influenza, the common cold, and gastro-intestinal infections to more severe illnesses such as COVID-19, viruses have had significant impacts on human health. It's important to note that scientists have identified viruses that can infect a variety of cell types, including fungal cells. Moreover, as new viruses evolve, they often find a suitable environment to spread within large human populations.
The presence of an envelope or the overall shape of a virion may not provide specific information about the diseases caused by the virus or which species it can infect, but these characteristics are helpful for the initial classification of viruses. These aspects, while not indicative of the pathogenic nature of the virus, are the foundational elements used in viral taxonomy.
Furthermore, evidence indicates that there could be new viruses emerging in the future with higher mortality rates, capable of spreading rapidly through the global population. Therefore, the relationship between viruses and human disease is well-established and has great significance for public health and medical research.
