Facts about SARS-CoV-2 the Coronavirus
causing the disease COVID19

(Current 15th March 2020)

  • The virus is in the same family (coronavirus) as many common cold viruses, but it is a new
    (novel) virus so there is no widespread human immunity to the virus.
  • The majority (80%) of infected people get mild cold/ flu like symptoms ie fever, cough,
    headache, tiredness and muscle pain. A moderate number of infected people get abdominal
    symptoms including diarrheoa. 15% are more severe and may require admission to hospital.
    5% of cases require critical care.
  • The virus is currently thought to be around 6 times more deadly than Influenza in adults but
    not children. The death rate for influenza is 0.1% of population. The death rate for SARSCoV-2 currently estimated 0.6 – 3.6%.
  • Elderly >60 years are more vulnerable, but healthy young adults can get very sick or die from the disease COVID 19 (just like the flu).
  • Children and adolescents don’t seem to get as sick as adults, but children are viral carriers so
    they spread the disease easily. A small proportion of children from studies in Wuhan, China required intensive medical care (ICU).
Transmission of SARS-CoV-2
  • Is by droplet usually by sneezing, coughing or kissing (within a radius of 1.5 metres).
  • Faecal fomites (ie virus genetic material) has been found in faeces of infected patients.
  • The Virus lives on hard surfaces for up to 72 hours, so touching the surface and putting your hand in your mouth can cause infection.
  • Can occur from infected patients with no symptoms (ie they look healthy)
Treatment of COVID19
  • Currently treatment is supportive for mainly the lung complications of the infection. This may
    in severe cases require oxygen support and mechanical ventilation.
  • Antivirals (to reduce viral load and therefore infection severity) that have already been
    approved for other viral infections, are being actively trialled across the world.
  • Vaccines generally take 18 – 24 months or even longer to develop, since they have to go
    through various large trials so that they can be given to healthy individuals.
