🦠 Kovid

Kovid is a small CLI app to fetch data surrounding the coronavirus pandemic of 2019. I found myself checking Wikipedia constantly for information so I thought I'd build this to provide info directly in the terminal. It's where some of us spend time more.

Code contribution and ideas welcome.

⚙️ Installation

To install:

  • ️ Wash your hands with soap and water for at least 20 seconds.

  • Run gem install kovid.

It's recommended you update often with gem update kovid.

⚒️ Usage

You can run kovid --help to see the full list of available commands.

Commands Overview

😷 Fetching

  • kovid check COUNTRY aliased as kovid country COUNTRY.
  • kovid check COUNTRY -f aliased as kovid country COUNTRY --full.

You can get continental information with the following commands:

  • kovid africa.
  • kovid europe.
  • kovid eu. (The European Union)
  • kovid sa. (South America)
  • kovid asia.
  • kovid world. (Worldwide Statistics)


You can fetch US state-specific data:

  • kovid state STATE OR kovid state "STATE NAME".


You can fetch province specific data:

  • kovid province PROVINCE or kovid province "PROVINCE NAME".

😷 Comparing

  • kovid compare FOO BAR (sorts by cases DESC).
  • kovid compare FOO BAR -f OR kovid compare FOO BAR --full (sorts by cases DESC).

Where FOO and BAR are different countries.

You can compare as many countries as you want; kovid compare FOO BAR BAZ OR kovid compare FOO BAR BAZ -f


You can compare US states with:

  • kovid compare STATE STATE Example: kovid states illinois "new york" california

You can compare provicnes with:

  • kovid provinces PROVINCE PROVINCE Example: kovid provinces ontario manitoba

😷 History

  • kovid history COUNTRY (full history).
  • kovid history COUNTRY N (history in the last N days).

NOTE: If you find it irritating to have to type kovid state STATE, covid state STATE works as well.

Histogram (Experimental) 🧪

kovid histogram COUNTRY M.YY (draws a histogram of cases in the given month M and years YY) (If the histogram appears messy, you might want to resize your window.)

👩🏾‍🔬 Experimental Feature
