use waste water testing to highlight hotspots

Scientists say waste water can be tested to show hotspots for virus in excretions. Netherlands and Sweden in particular have done work on this. One advantage is that infection can show up earlier than by symptoms and it can give a picture of a population. If it proves to be effective, it would help us monitor for areas with problems or surges in the illness

Since this is going to remain in our population long term and is hard to test for, this can give alerts to authorities
