The virus causes measles, a highly contagious disease transmitted by respiratory aerosols that triggers a temporary but severe immunosuppression.Symptoms include fever, cough, runny nose, inflamed eyes and a generalized, maculopapular, erythematous rash and a pathognomonic Koplik spot seen on buccal mucosa opposite to lower 1st and 2nd molars.
An electron micrograph of the measles virus. Measles is caused by the measles virus, a single-stranded, negative-sense, enveloped RNA virus of the genus Morbillivirus within the family Paramyxoviridae. [51] The virus is highly contagious and is spread by coughing and sneezing via close personal contact or direct contact with secretions. [52 ...
Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level. It is a specialized field of study in virology. [1] Pathogenesis is a qualitative description of the process by which an initial infection causes disease. [2]
Diseases in humans associated with viruses classified in this genus include measles; in animals, they include acute febrile respiratory tract infection and Canine distemper. [3] In 2013, a wave of increased death among the Common bottlenose dolphin population was attributed to morbillivirus.
A number of important human diseases are caused by paramyxoviruses. These include mumps, as well as measles, which caused around 136,200 deaths in 2022. [11] The human parainfluenza viruses (HPIV) are the second most common causes of respiratory tract disease in infants and children. There are four types of HPIVs, known as HPIV-1, HPIV-2, HPIV ...
Subacute sclerosing panencephalitis (SSPE), also known as Dawson disease, is a rare form of progressive brain inflammation caused by a persistent infection with the measles virus. The condition primarily affects children, teens, and young adults.
Alright—so a quick review of measles: measles is an airborne pathogen that’s highly contagious, and causes cough, conjunctivitis, and coryza, as well as complications like pneumonia and encephalitis, and can be prevented through vaccination. [1] Image 17 of measles video
Most recent reported cases of measles in Portugal are originally imported from other European countries (United Kingdom, France and Romania), Africa (Angola, South African and Ethiopia) and Asia (China). [144] Since 2004, Portugal reported 22 confirmed cases of measles. Virus isolates from 2005 and 2008 outbreaks belong the genotype D4. [145]
