The primary objective of this microsite is collate information from the Barts-MS blog and to answer questions about COVID-19 in relation to multiple sclerosis and its treatments. You can either ask questions on the blog or via the Google form below. We will make every effort to keep up-to-date to help everyone get through the next few months.


  • COVID-19 or coronavirus disease 2019 refers to the infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
  • The disease was first identified in Wuhan, China, and has spread globally, resulting in a COVID-19 pandemic. COVID-19 infection is very non-specific; common symptoms include fever, cough and shortness of breath. Associated flu-like symptoms such as muscle pain, sputum production and sore throat are less common.
  • Please note the COVID-19 refers to corona virus disease due to the SARS-CoV-2 virus that was first identified in 2019.
  • Please note the majority of COVID-19 cases are mild with a small number progressing to severe pneumonia and multi-organ failure. The mortality of COVID-19 is about 3%, but ranges from ~0.2% in those less than 20 years to up to 15% in those over the age of 80 years.
  • Other risk factors for severe COVID-19 infection include male sex, smoking, pre-existing lung disease (e.g. severe asthma), comorbidities, in particular, hypertension and diabetes, and possibly being immunocompromised or suppressed.
  • COVID-19 is spread from one person to another via respiratory droplets produced during coughing and sneezing. Time from exposure to onset of symptoms is generally between 2 and 14 days, with an average of five days.
  • The standard method of diagnosis is by the molecular detection of the virus from a nasopharyngeal or throat swab. A small number of people can present with diarrhoea and the virus can be detected in the stool.
  • Because the virus is an enveloped virus and has a cell-like membrane it is susceptible to detergents. Therefore frequent hand-washing is one way to prevent infection. Hand sanitizers work as well, but need to contain more than 60% alcohol to disrupt the viral envelope.
  • Other preventive measures include maintaining a distance from others, and trying not to touch one's face.
  • The use of face masks is more controversial. Face masks are generally recommended for those who suspect they have the virus and for healthcare workers and carers.
  • At present there is no vaccine or specific antiviral treatment for COVID-19.
  • The management of COVID-19 involves symptomatic therapies, ventilatory and other supportive care and isolation.
