Single-stranded DNA viruses are a type of virus that contains a single strand of DNA helix as their genetic material. These viruses are also known as ssDNA viruses or Monopartite viruses. Some common synonyms for single-stranded DNA viruses include unenveloped DNA viruses, non-enveloped DNA viruses, filamentous DNA viruses, linear DNA viruses, parvoviruses, and circoviruses. These viruses infect a wide range of hosts, including plants, animals, and bacteria. Single-stranded DNA viruses are responsible for several diseases in humans and animals, including hepatitis B and C, certain types of cancers, and respiratory tract infections. Understanding the characteristics and synonyms of single-stranded DNA viruses is essential in developing and implementing effective preventive measures and treatments against these viruses.
