An endless amount of information is being thrown at the public right now in regards to COVID-19Opens in a new tab, a.k.a. “the coronavirus,” but, sadly, much of it seems to simply add up to nothing more than noise. Thankfully, there are some sources that are able to consolidate all of the data being flung around the internet into intelligible, bite-sized video summaries. Like this one from YouTube channel, KurzgesagtOpens in a new tab, which breaks down how the virus that causes COVID-19 works, as well as what we can do as a world community to stop it.
For those unfamiliar, Kurzgesagt—which literally translates to “in a nutshell” from the original German word—is a channel dedicated to educating people on complex topics that range from genetic engineeringOpens in a new tab to nuclear fallout scenariosOpens in a new tab to the creation of “stellar engines.”Opens in a new tab As with other major YouTubersOpens in a new tab, Kurzgesagt has churned out a video on COVID-19 in response to the pandemic. This one focuses, in large part, on how SARS-CoV-2, the virus that causes COVID-19, manages to infect people and damage their health.
While the video covers some aspects of the pandemic that have already been harped on quite a bit—like the importance of hand washingOpens in a new tab and social distancingOpens in a new tab—the channel’s look at how exactly SARS-CoV-2 does such an unholy amount of damage to a person’s body, particularly their lungs, is refreshingly insightful.
The SARS-CoV-2 virus penetrating a healthy epithelial cell. Kurzgesagt
Kurzgesagt’s COVID-19 explainer video shows how SARS-CoV-2 enters the body through openings in the face, and then makes its way into the intestine, spleen and/or lungs. The video goes on to illustrate how SARS-CoV-2 is able to connect to the membranes of epithelial cells, which Science DirectOpens in a new tab notes are cells “Specialized for absorption, secretion or to act as a barrier” between one’s “self” and “non-self.” Epithelial cells, in other words, line a body’s surfaces, including its skin, the inside of its gutOpens in a new tab, its ducts, etc.
Once SARS-CoV-2 has penetrated the epithelial cells lining the lungs, it then gets to work making them reproduce copies of itself, before it finally gives the “instruction” for the host cells to collapse and die. Furthermore, the video explains how SARS-CoV-2 encourages the body to damage itself with an overreactive immune response; it’s able to pull this off by infecting immune cellsOpens in a new tab themselves, and putting them into a “fighting frenzy.” This frenzy not only wastes a host’s immune cells, but also damages their healthy cells.
Shoutout to @ourworldindataOpens in a new tab. Working with them over the years has been a delight. They want to inform people about the true state of the world – and how to make progress against the problems the world faces. They are a big inspiration for us. https://t.co/QjP1WPpYbUOpens in a new tab

Because SARS-CoV-2 attacks the epithelial cells lining the lungs, it can lead to serious respiratory illnesses, which can permanently damage a person’s ability to breathe properly, or worse. This is exactly why it’s so important for hospitals around the world to make sure they have ventilators, which are, in many places, in short supply. Luckily, people are banding together to come up with solutions for that problemOpens in a new tab, as well as many others posed by COVID-19. Because just like immune cells, people can work together to stop the spread of this pandemic. Hopefully they don’t mistakenly attack each other too much in the process.
