"AIDS virus" is HIV, Human Immunodeficiency virus. It causes AIDS, Auto-immunodeficiency syndrome.

HIV is a retrovirus because it uses reverse transcriptase in replication.

Polio is a picornavirus.

Both have RNA genomes, and positive sense.

They are also both icosahedron shaped.

HIV is much bigger: 100 diameter, rather than 30 which is polio.
