Canine distemper virus is closely related to measles virus and is the most important viral disease of dogs. The disease (which was first described in 1760, by Edward Jenner, the pioneer of smallpox vaccination, is highly contagious, but is well controlled by vaccination. In the 1990s, thousands of African lions died from the infection, which ...
Orthomyxoviridae (from Ancient Greek ὀρθός (orthós) 'straight' and μύξα (mýxa) 'mucus') [1] is a family of negative-sense RNA viruses.It includes seven genera: Alphainfluenzavirus, Betainfluenzavirus, Gammainfluenzavirus, Deltainfluenzavirus, Isavirus, Thogotovirus, and Quaranjavirus.
The virus exits the host cell by nuclear egress, and nuclear pore export. Birds and pigs serve as the natural host. [ 9 ] [ 7 ] The virus is known to cause "immunosuppressive conditions" in animals that are infected; as well as having the ability to jump between species, creating difficulty in identifying the origin of infection.

Orthopoxvirus is a genus of viruses in the family Poxviridae and subfamily Chordopoxvirinae.Vertebrates, including mammals and humans, and arthropods serve as natural hosts. . There are 12 species in this gen
Zika fever (also known as Zika virus disease) is an illness caused by Zika virus. [80] Around 80% of cases are estimated to be asymptomatic, though the accuracy of this figure is hindered by the wide variance in data quality, and figures from different outbreaks can vary significantly. [ 81 ]
Polyomaviridae is a family of viruses whose natural hosts are primarily mammals and birds. [1] [2] As of 2024, there are eight recognized genera. [3]Fourteen species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.
Like other members of the Paramyxoviridae family, it produces enveloped virions, and is a negative-sense single-stranded RNA virus. The virus is particularly fragile and is quickly inactivated by heat, desiccation, and sunlight. [14] Measles virus evolved from the then-widespread rinderpest virus most probably between the 11th and 12th ...
