Coronavirus FYI
Typical Symptoms

  • ​COVID-19 typically causes flu-like symptoms including a fever and cough.
  • In some patients - particularly the elderly and others with other chronic health conditions - these symptoms can develop into pneumonia, with chest tightness, chest pain, and shortness of breath.
  • It seems to start with a fever, followed by a dry cough. 
  • After a week, it can lead to shortness of breath, with about 20% of patients requiring hospital treatment.
  • Notably, the COVID-19 infection rarely seems to cause a runny nose, sneezing, or sore throat (these symptoms have been observed in only about 5% of patients). 
  • Sore throat, sneezing,and stuffy nose are most often signs of a cold.
  • ​​80.9% of infections are mild (with flu-like symptoms) and can recover at home.
  • 13.8% are severe, developing severe diseases including pneumonia and shortness of breath.
  • 4.7% as critical and can include: respiratory failure, septic shock, and multi-organ failure.
  • in about 2% of reported cases the virus is fatal.
  • Risk of death increases the older you are.
  • Relatively few cases are seen among children.

​Incubation Period
2 - 14 days represents the current official estimated Incubation
Average incubation period observed: 3.0 to 5.2 days 
Possible outliers: 0 - 27 days 

The transmission rate which is defined as the number of newly infected people from a single case
is currently 2 to 3 people. An outbreak with a transmission number below 1 is needed for an outbreak to disappear.

There is evidence that human-to-human transmission has occurred among close contacts​

​Understand the statistics
The flu causes a 0.1% death rate or
​1 out of 1000 people will die
The coronavirus causes a 3.4% death rate or
​3.4 people  out of 100 will die per WHO as March 3rd
It is very early to make any conclusive statements about what the overall mortality rate will be for the
novel coronavirus, according to the World Health Organization.
The true case fatality rate might be off by orders of magnitude and has been estimated to be much higher.
This may be due to not all cases, deaths or recoveries have been reported yet.
May not know the real death rate until the virus has subsided.
The formula currently being used is: cumulative current total deaths / current confirmed cases.

Front the analysis of death cases, it emerged that the demographic profile was mainly male, accounting for 2/3, females accounting for 1/3, and is mainly elderly, more than 80% are elderly over 60 years old, and more than 75% had underlying diseases present such as cardiovascular and cardiovascular diseases, diabetes and, in some cases, tumor.
