Scene Description:Up to now, novel coronavirus pneumonia has been diagnosed in the United States by more than 790 thousand cases, and technology companies have been actively providing various kinds of help. The novel coronavirus pneumonia, the two founder of Instagram, has recently developed a website to visualize the average number of new pneumonia infections in a real-time manner, so that people can have a panoramic view of the spread of the epidemic situation in various states.
key word:Tracking the spread rate of the founder of instagram
On April 10, 2012, instagram, a startup with only 13 employees, was acquired by Facebook for $1 billion, the largest acquisition ever made by Facebook at that time.
The founders of instagram, Kevin systrom and Mike Krieger, were 28 and 25, respectively. At that time, it became a myth that inspired more entrepreneurs.
- Two young and promising founders
In 2018, the two left Facebook because of internal conflicts.
Now, two years after leaving Facebook, instagram’s founders are teaming up again to develop new products, this time for us epidemic prevention and control.
Two founders, Kevin systrom and Mike Krieger, recently launched a new websiteRt.live，The website is not like the general data statistics website, only provides the original covid-19 data, but uses statistical methods to measure the spread speed of the virus.
- It’s the first product they’ve jointly launched since they left Facebook
“We build Rt.live Because we believe that the basic infection number RT is one of the best ways to understand the transmission mode of covid-19. “Said founder Krieger.
Designed to monitor the spread of the epidemic Rt.live
The RT tracked by the website is the basic number of infections in epidemiology,It is used to measure the average number of people who are infected with infectious diseases and infect others.
If RT is higher than 1, it means that covid-19 is spreading faster in the population, and lower than 1 indicates that the virus is fading away.
Developed by Kevin and Mike Rt.live In other words, the value of RT will be displayed intuitively, so that we can see that the “home order” policy can effectively reduce the spread rate of the virus, thus persuading people to stay indoors.
- Last week, the RT value of each state in the United States, green means less than 1, red means greater than 1, and South Dakota RT = 2.1 is the highest in the country
- According to the data updated on April 19, only a few states have RT less than 1
- More states have reduced their RT to below 1, according to the data updated on April 21
Through the site, users can filter by region, so you can see that western states are better at controlling covid-19 than southern states, and more and more states are on the mend. States that did not implement the home order were not optimistic on average.
Take a specific example. Rt.live It shows that RT has dropped to 0.54 due to active social segregation in New York state.
- The peak value of RT in New York City reached 4.3. After the implementation of the home order on March 20, RT decreased significantly
- The RT value of North Dakota without home isolation measures showed no downward trend
The data for the website comes from the covid-19 tracking project, which Kevin has Rt.live The modeling system is uploaded to GitHub.
In addition, this tool can also be used as a reference for people to return to work in various states of the United States, and make corresponding strategies at any time according to the changes of the situation.
Instagram founder, cross-border medical?
Seeing this news, many people will also be surprised: for the photo application giant, it seems a bit cross-border to establish a Medical Statistics website?
But in fact, the two are not as unrelated as they seem.
Kevin has been studying for a long timeViral transmission,Because it’s one of his jobs to help instagram grow rapidly.
- This is a study of the spread of the virus
“Kevin is studying how to use open source data to calculate RT every day, and publishes his analysis notes,” Krieger said. “
They want to visualize the data so that anyone can see the performance of their state in curbing the spread of the epidemic.
- The project was well received on twitter
“When states decide whether and how to open up, they’re going to have to manage their infection rates carefully, and we want to be like this,” Krieger said Rt.live Such tools can help in this regard. “
On March 19, Krieger began publishing his own statistical model to track coronavirus infections and deaths. “Kevin and I have been discussing ways to work together, and my first job was to do data visualization / analysis at Meebo,” Krieger said. “
While Kevin was doing data analysis, Krieger set up the site, which was their previous front-end and back-end roles at instagram.
They have created miracles. What about this cooperation?

Kevin and Mike’s success is no accident. Good education background, strong self-learning ability, and sensitive capture of user preferences are all factors contributing to instagram’s success.
Kevin systrom has a good family and loves playing computer games. He studied at Stanford University in 2002 and received his bachelor’s degree in management science and Engineering in 2006.
Mike Krieger, from Sao Paulo, Brazil, moved to California in 2004 to study at Stanford University.
Kevin, who has never received formal programming education, has set up some websites on his own during his college years. His programming knowledge is self-taught in the evening.
After graduation, Kevin developed an HTML5 based check-in app, burbn, and invited Krieger, who had known him in college, to join him. After working together, they decided to transform burbn into a software to share and filter photos for free.
It took them just eight weeks to develop the first version of instagram. Since then, instagram has been on the top of the list of major app stores at the speed of rocket launch, which is beyond the expectations of the two founders. “We knew it would be successful, but we didn’t expect it to be so successful. “
- Since then, instagram’s monthly live users have grown exponentially
Suddenly, it has been nearly 10 years since instagram was launched that the two entrepreneurial partners have joined hands again.
Krieger seemed very happy about this collaboration: “it’s great to be able to work together again – we can turn ideas into products in a few days, because we have common memories and tacit understanding. “
Perhaps the two gods did not expect to create “viral transmission” products like instagram, but expected to Rt.live To a certain extent, to prevent the spread of the real virus, as soon as possible to end the epidemic.
