  • ℹ️ Description
Ninja Nerds,
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. It is believed that COVID-19 was transmitted from pangolin to humans (current theory).
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).
Ninja Nerd Lectures has compiled the most up to date and recent data on COVID-19 as of March 15, 2020. Please follow along with this lecture to understand the origin and zoonosis of COVID-19, the routes of transmission, epidemiology (current as of 3/15/2020), pathophysiology, and diagnostic tests used to identify COVID-19.
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.

💬 Comments on the video

This is my colleague, Zack whom I’ve had the pleasure of working with as a chemistry tutor at Northampton Community College. He’s an absolute brilliant educator with an incredible memory and passion for science. True story: when Zack started the Ninja Nerd Science channel, it was part of his tutoring position at the college and was meant as a supplementary addition to learning for students in general chemistry, organic chemistry, biochemistry and anatomy & physiology. Our boss at the time didn’t like the length of Zack’s videos. She told him to stop making the videos because ‘they’re too long and nobody would watch them’. Zack responded with something along the lines of ‘the hell with that!’ and quit the position soon after to continue with the channel. I said it to him then and I’m saying it again now: Good for you, Zack! You deserve all the recognition you’ve acquired and more! As a result of your burning passion for science and teaching, you’ve reached countless lives around the world and helped them understand such important, complex topics. Keep doing what you’re doing buddy! You were born for it.

Gotta love the "this is cool guys" when talking about a virus. Interluken.. that is just fun to say!

Hey there,

wow, learned a bunch of human-biosystemic connections.

There are some errors in the video:

* In the R0-graph, you axis says -- and you also said it -- R0 increasing over time. But what you mean is that the number of infected increases, R0 stays constant! ('m physicist and sensitive about that difference).
* With R0 < 0, the decrease would be first a stronger decrease, then slowing down; not as you painted the number of infected staying constant and then an acellerated decrease. At least as long as we stay in this simplified exponential model.

This is the thing that we should be seeing daily in news, not the non-sense toilet paper panic or financial chaos.

45:00 hilarious that you mention mortality as a diagnostic indication. ‘How do you know heart function is insufficient?’ ‘Well the patient is dead, dr Benway.’

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.
