COVID-19 a.k.a BeerFlu Telegram Bot

Mar 18, 2020

Covid19 pandemic will go down as the inflection point for our generation. Just like 9/11, 2008 mortgage crisis, 1920 stock crash and Spanish flu, its many disasters rolled into one. Stock market drop (steepest in history) + highly contagious virus with 2%+ mortality + epic trade wars with a spicy topping of incompetent leadership = one hell of a disaster.

As a tribute to this epic event I made a telegram bot to notify me about the total number of cases and the total number of deaths due to beer-flu at any give time - live. This was the first telegram bot I actually hosted on a cloud server. All of my previous bots were either self hosted on a SBC or used serverless functions to do the trick but this time I wanted to do it differently. I bought a cheapo $2/mo vps on 1&1 (cheapest vps plan I could find) pushed the script using SSH and ran it after detaching the terminal. All of this in under 30 minutes !

Here's some really poorly written code >

if __name__ == '__main__':
    main()

Here's what is does :

Scrape the data from /www.worldometers.info and parse it using beautiful soup.
Reply with this data every-time any message is sent to the bot.
Its basically a zombie mutation of an echo bot.

~~I am planning to enhance its functionality by giving it access to country-wise data and rates available on worldmeters.~~ UPDATE: Added the country-wise inquiring feature. Check it out here.

To try this bot use bot id > @CovidCaseReporter_bot on telegram. Enter 'info' to get summary and 'country <name>' to get specifics.

Stay Safe !
