Measles

Now relatively rare in the UK Older children have more severe disease Caused by the Morbillivirus, which is a type of paramyoxovirus This is a single stranded, enveloped RNA virus It is a highly contagious infection of the respiratory system, and can be passed on by airborne transmission, via droplets expelled in coughing, sneezing and respiration.

Key to blocking influenza virus may lie in a cell's own machinery

Viruses are masters of outsourcing, entrusting their fundamental function - reproduction - to the host cells they infect.

Study Identifies Influenza Viruses Circulating In Pigs And Birds That Could Pose A Risk To Humans

In the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people.

Pathogenesis of Noroviruses, Emerging RNA Viruses

Human noroviruses in the family Caliciviridae are a major cause of epidemic gastroenteritis. They are responsible for at least 95% of viral outbreaks and over 50% of all outbreaks worldwide. Transmission of these highly infectious plus-stranded RNA viruses occurs primarily through contaminated food or water, but also through person-to-person contact and exposure to fomites. Norovirus infections are typically acute and self-limited. However, disease can be much more severe and prolonged in infants, elderly, and immunocompromised individuals. Norovirus outbreaks frequently occur in semi-closed communities such as nursing homes, military settings, schools, hospitals, cruise ships, and disaster relief situations. Noroviruses are classified as Category B biodefense agents because they are highly contagious, extremely stable in the environment, resistant to common disinfectants, and associated with debilitating illness. The number of reported norovirus outbreaks has risen sharply since 2002 suggesting the emergence of more infectious strains. There has also been increased recognition that noroviruses are important causes of childhood hospitalization. Moreover, noroviruses have recently been associated with multiple clinical outcomes other than gastroenteritis. It is unclear whether these new observations are due to improved norovirus diagnostics or to the emergence of more virulent norovirus strains. Regardless, it is clear that human noroviruses cause considerable morbidity worldwide, have significant economic impact, and are clinically important emerging pathogens. Despite the impact of human norovirus-induced disease and the potential for emergence of highly virulent strains, the pathogenic features of infection are not well understood due to the lack of a cell culture system and previous lack of animal models. This review summarizes the current understanding of norovirus pathogenesis from the histological to the molecular level, including contributions from new model systems.

Nosocomial transmission of avian influenza virus A (H7N9)

Since the first notification in March 2013 through to 15 October 2015, a total of 679 laboratory confirmed cases of human infection with avian influenza A (H7N9) viruses, including 275 (40%) deaths, have been reported to the World Health Organization.1 These individuals have presumably contracted their infection in China directly from infected birds or their environment, particularly when visiting live poultry markets. Limited human to human transmission has been suspected in a few clusters of cases of family members.2 In a linked article, Fang and colleagues report on a presumed case of nosocomial, human to human, transmission of influenza A (H7N9) between unrelated individuals.3 Both patients, showing symptoms, spent time in the same hospital room, were infected with comparable strains, and—because no other common exposure was identified—the authors concluded that nosocomial infection was the most likely route of transmission.

Virus Mind Map

A basic virus mind map of the DNA and RNA viruses that I made. I may continue to add to it and publish a more detailed one in the future. The link should allow you to download the full PDF version. Hope it helps some people in microbiology! Viruses Mind Map
