RNA viruses

RNA viruses are a type of virus that carry their genetic information in the form of ribonucleic acid (RNA) instead of DNA. These viruses can infect various organisms, including humans, animals, and plants. When an RNA virus enters a host cell, it uses the cell's machinery to replicate itself, leading to infection. Some well-known RNA viruses include the influenza virus, HIV, and the coronavirus responsible for COVID-19. RNA viruses often mutate quickly, which can make them challenging to control and treat with vaccines and antiviral medications.
