Human coronaviruses that can cause emergencies

How Coronaviruses Cause Infection—from Colds to Deadly Pneumonia

The 2019 novel coronavirus (2019-nCoV) behind the ongoing outbreak - which the World Health Organization has declared an international public health emergency - was named after the family of viruses it belongs to. The term “coronavirus” may have initially been unfamiliar to many, but most everyone has encountered milder forms of such viruses, of which four strains cause about a fifth of common ...

Genetic Mutations that Cause Coronary Artery Disease

Neuroinvasion by human respiratory coronaviruses.

Human coronaviruses (HCoV) cause common colds but can also infect neural cell cultures. To provide definitive experimental evidence for the neurotropism and neuroinvasion of HCoV and its possible association with multiple sclerosis (MS), we have performed an extensive search and characterization of HCoV RNA in a large panel of human brain autopsy samples. Very stringent reverse transcription-PC...

Clostridium, a “difficile” infection that can cause a reactive arthritis

Background Clostridium difficile infection (CDI) is a common cause of antibiotic-associated diarrhea and can be difficult to cure. Most patients with CDI present only colonopathy and in fewer cases extra intestinal features were described such as reactive arthritis (ReA). We present a series of cases with CDI-associated reactive arthritis (CDI-AReA), admitted between 2011-2014 in the National I...

A review of coronaviruses focusing on SARS-CoV-2 (2019-nCoV) the cause of COVID-19

Coronaviruses, enveloped positive single-stranded RNA viruses, have become significant pathogens for humans and other vertebrates since the outbreak of SARS (severe acute respiratory syndrome) in 2002 in China. These viruses could infect the respiratory tract of humans and other animals. The outbreaks of SARS and MERS (Middle East respiratory syndrome), which Bats are thought to be the origin o...
