This Twitter bot automatically posts COVID-19 sewage surveillance data.

The bot is designed for people interested in epidemiology, public health trends, and alternative COVID tracking methods beyond case reporting. It provides regular automated updates on wastewater-based disease surveillance.

From the sources
I built a new Twitter bot today: @covidsewage . It tweets a daily screenshot of the latest Covid sewage monitoring data published by Santa Clara county. I’m increasingly distrustful of Covid numbers as fewer people are tested in ways that feed into the official statistics. But the sewage numbers don’t lie! As the Santa Clara county page explains: SARS-CoV-2 (the virus that causes COVID-19) is shed in feces by infected individuals and can be measured in wastewater. More cases of COVID-19 in the community are associated with increased levels of SARS-CoV-2 in wastewater, meaning that data from wastewater analysis can be used as an indicator of the level of transmission of COVID-19 in the…from simonwillison.net

Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor.
