Is virii correct? The correct plural is ‘viruses’. ‘Virii’ is wrong for two reaons: 1) The Latin plural of word ending in -us is not -ii. … 2) ‘Virus’ doesn’t have a Latin plural, because its meaning is like (in the sense of not having a plural) ‘sand’: it already denotes a multitude.
also, Why is the plural of virus not viri? virus has no attested plural in Latin. The reason we don’t use a Latin plural for ”virus” is that there is none. If ”virus” were 2nd declension masculine or feminine, its plural would be ”viri”. ”Virii” would be the 2nd declension plural of ”virius” which is not a word.
Is virii plural or singular? Thus the plural virii is that of the nonexistent word virius. The form viri would also be incorrect in Latin.

Qual é a diferença entre um vírus e um virion?
A virion is an entire virus particle consisting of an outer protein shell called a capsid and an inner core of nucleic acid (either ribonucleic or deoxyribonucleic acid—RNA or DNA). The core confers infecciosidade, and the capsid provides specificity to the virus.

What is the function of a virion?
A complete virus particle is called a virion. The main function of the virion is to deliver its DNA or RNA genome into the host cell so that the genome can be expressed (transcribed and translated) by the host cell. The viral genome, often with associated basic proteins, is packaged inside a symmetric protein capsid.
