Myxovirus is a genus of viruses that includes several species known for causing respiratory and neurological diseases in humans and animals. Some common synonyms for myxovirus include orthomyxovirus, paramyxovirus, and pneumovirus. While these terms are often used interchangeably to describe viruses with similar characteristics, each genus has unique features that distinguish them from one another. Orthomyxoviruses, for example, are known for causing the flu, while paramyxoviruses are typically associated with conditions such as measles, mumps, and respiratory syncytial virus (RSV). Pneumoviruses, on the other hand, are responsible for causing severe respiratory infections in humans, birds, and livestock.
