COVID-19 | Coronavirus: Epidemiology, Pathophysiology, Diagnostics

Official Ninja Nerd Website: ninjanerd.org
Ninja Nerds!
In this lecture Professor Zach Murphy will present on COVID-19- Coronavirus: Epidemiology, Pathophysiology, Diagnostics.
What is Corona virus? What is COVID-19? Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). Coronavirus disease (COVID-19) caused by SARS-COV2 is a new strain that was discovered in 2019 and has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death (WHO, 2020).
As new information and research is published we will continue to provide updates on COVID-19 and ensure all of our viewers are kept up to date on the most recent data. We hope you enjoy this lecture and be sure to support us below!

[@alexkoz]

Do you see anything wrong with him putting total case numbers in the denominator?

[@alexkoz]

@@RobinHoodII He got the math spectacularly wrong! Try this... 1000 people test positive for the virus. This virus will start killing them in about 20 days and will ultimately kill 100 of them. On day 19, what's the mortality rate? Let's see. Oh, we already know this! We take the # deaths and divide it by # of cases. Okay, then 0 / 1000 = 0% mortality rate. Zero! This is obviously a complete failure of math and reason, but that's what he's doing. We're in an exponential curve, so a lot of those 153,517 cases are only a week or two old and on March 15th simply haven't had a chance to either recover or die and CANNOT be included in the denominator. They are not in the same cohort as people who died. Does this make sense? Ok, then what should this number be? Well, it takes at least a week from the diagnosis to death, so the cases from 7 days before, on March 7th, would be the most conservative estimate. That was only 106,000 cases. So, 5,735 / 10,6000 is 5.5% (and most likely much larger number). Putting 153,517 cases in the denominator is like saying that people recover or die the very day they get diagnosed, which is absurd. Of course, there are unreported cases that we need to account for. HOWEVER, what most people do, they take the 3.7%, then assume that there are 10X more cases than reported, then divide 3.7% by 10, get a fraction of a percent and say things like.. oh , this is just like the flu… and then go to a party. This is a dangerous number not to get right because it leads to behavior. The virus is way deadlier. If he wants to speculate on the mortality rate, he gotta start with a much bigger number because 3.7% of CONFIRMED cases is literally a mathematical impossibility.

[@barbaranowicki8833]

This is so good. Epidemiology, Pathophysiology, and Diagnostics? You covered it all. This is so satisfying. thanks for all of the hard work, time, and effort put into the research, planning, and presentation of this lecture. i thoroughly enjoyed it and learned a lot. i am very grateful for this.

I have been a RN for 30 years…Where were you when I had so many Pathophysiology questions over the years and was lost when my MDs would try to explain. At one time I worked ICU and then have worked in hemodialysis for 18 years. Thanks for such a simplified and interesting way for me to further understand disease processes.
