Hi @learihana and welcome to Mayo Clinic Connect. So much is being debated with COVID-19 (SARS-CoV-2) as researchers scramble to test and collect evidence for solid answers. Here I've gathered some articles from trusted resources that are constantly being updated as things develop:

- How we know disinfectants should kill the COVID-19 coronavirus (Chemical & Engineering News) https://cen.acs.org/biological-chemistry/infectious-disease/How-we-know-disinfectants-should-kill-the-COVID-19-coronavirus/98/web/2020/03

This article talks specifically about spraying the outdoors:
- Does disinfecting surfaces really prevent the spread of coronavirus? (ScienceMag) https://www.sciencemag.org/news/2020/03/does-disinfecting-surfaces-really-prevent-spread-coronavirus

In the early days of COVID-19, before it was named, the first hit countries were trying everything because so little was known. Spraying outdoors has little effect according to early reports. Has there been spraying in your municipality?
