The name of the family, Poxviridae, is a legacy of the original grouping of viruses associated with diseases that produced poxes on the skin. Modern viral classification is based on phenotypic characteristics; morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.
Chickenpox. Chickenpox, also known as varicella ( / ˌvɛrəˈsɛlə / VER-ə-SEL-ə ), is a highly contagious, vaccine-preventable disease caused by the initial infection with varicella zoster virus (VZV), a member of the herpesvirus family. [ 3][ 7][ 5] The disease results in a characteristic skin rash that forms small, itchy blisters, which ...
Molluscum contagiosum virus ( MCV) is a species of DNA poxvirus that causes the human skin infection molluscum contagiosum. [ 1] Molluscum contagiosum affects about 200,000 people a year, about 1% of all diagnosed skin diseases. Diagnosis is based on the size and shape of the skin lesions and can be confirmed with a biopsy, as the virus cannot ...
Orthopoxvirus replication cycle. Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host glycosaminoglycans (GAGs), which mediate cellular endocytosis of the virus. Fusion of the viral envelope with the plasma membrane releases the viral core into the host cytoplasm.
Monkeypox belongs to the family of poxviruses, which includes smallpox. The disease got its name after scientists discovered it among laboratory monkeys in 1958. The first monkeypox case in a ...
The virus is transmissible between animals and humans by direct contact to the lesions or bodily fluids. [5] The virus was given the name monkeypox virus after being isolated from monkeys, but most of the carriers of this virus are smaller mammals. [4] The virus is endemic in Central Africa, where infections in humans are relatively frequent.
Avipoxvirus. Avipoxvirus ( avian pox) is a genus of viruses within the family Poxviridae. Poxviridae is the family of viruses which cause the afflicted organism to have poxes as a symptom. Poxviruses have generally large genomes, and other such examples include smallpox and monkeypox. Members of the genus Avipoxvirus infect specifically birds.
Mpox ( / ˈɛmpɒks /, EM-poks; formerly known as monkeypox) [ 6] is an infectious viral disease that can occur in humans and other animals. [ 1] Symptoms include a rash that forms blisters and then crusts over, fever, and swollen lymph nodes. [ 1] The illness is usually mild, and most of infected individuals recover within a few weeks without ...
