Riboviruses are a group of viruses that contain ribonucleic acid (RNA) as their genetic material. They are known for their ability to replicate quickly and can infect a wide range of hosts, including animals, plants, and humans. Some well-known riboviruses include the influenza virus and the HIV virus. These viruses can cause various diseases, often leading to respiratory or systemic infections. Riboviruses are typically transmitted through direct contact, respiratory droplets, or vectors like insects. Understanding riboviruses is crucial for developing vaccines and treatments to combat the diseases they cause.
