Good to know.
We have a creek that runs through our place that usually has some water.
I thought this was interesting (that typically simis issues don’t normally accompany this virus)
Typical Symptoms
COVID-19 typically causes flu-like symptoms including a fever and cough.
In some patients - particularly the elderly and others with other chronic health conditions - these symptoms can develop into pneumonia, with chest tightness, chest pain, and shortness of breath.
It seems to start with a fever, followed by a dry cough.
After a week, it can lead to shortness of breath, with about 20% of patients requiring hospital treatment.
Notably, the COVID-19 infection rarely seems to cause a runny nose, sneezing, or sore throat (these symptoms have been observed in only about 5% of patients). Sore throat, sneezing, and stuffy nose are most often signs of a cold.
At the link there’s also examples of how it progressed with some patients.

I read somewhere with dirty water like creek water, filtering it first through a t shirt or other filter to get out the larger debris will extend the life of the Berkey filters. Good to know as they are not cheap!
