RNA Viruses

Reoviruses: Multisegmented, Double-Stranded, Linear; Important cause of diarrhea in young children; potentially fatal.
Picornaviruses: Non-enveloped, "Naked", Icosahedral; Include poliovirus (with vaccines).
Hepeviruses: Icosahedral; Include Hepatitis E virus (HEV)
Caliciviurses: Icosahedral; Include norovirus, a common cause of viral gastroenteritis and watery diarrhea.
Flaviviruses: Single stranded, Linear; Include arboviruses (arthropod-borne viruses) like dengue fever, yellow fever, Zika virus; also, some encephalitis viruses.
Togaviruses: Single-Stranded, Linear; Include rubella (German measles).
Matonaviruses: Single-Stranded, Linear; Include a various viruses and causes.
Retroviruses: Single-Stranded, Linear; Include HIV-AIDS and Human T-cell Leukemia Virus (HTLV) and are characterized by reverse transcriptase.
Coronaviruses: Enveloped, Icosahedral; Include the "common cold," SARS, and MERS-CoV.
Orthomyxoviruses: Multisegmented; Include influenza viruses.
Paramyxoviruses: Multisegmented; Include respiratory syncytial virus (RSV).
Rhabdoviruses: Helical; Rabies is a common example.
Filoviruses: Helical; Example: Ebola Virus
Arenaviruses: Multisegmented; Include some viral hemorrhagic fevers
Bunyaviruses: Multisegmented; This group includes many viruses that cause hemorrhagic fevers, such as California encephalitis (with sandfly), Rift Valley fever, Hantavirus.
Deltaviruses: Enveloped, Single-Stranded, Circular; Hepatitis D virus requires Hepatitis B virus for replication.

Additional Information

Coxsackievirus: Herpangina (mouth blisters, fever), Hand, foot, and mouth disease, Aseptic meningitis, Myocarditis, Pericarditis
Echovirus: Rhinovirus—"common cold," Aseptic meningitis
West Nile Virus: Acute asymmetric flaccid paralysis, Meningoencephalitis
Chikungunya Virus: Co-infection with dengue virus
