Has "cluster" been defined previously and I missed it? I'm interested to know how a case qualifies as cluster vs community spread.
Vaguely at best.
We know something like The Waterford and Sanderson Farms are classified as clusters. The same for a residence that one person brings it home, and then gives it to the other people living there.
Beyond that, they haven't said what else they define as a cluster. IIRC, someone asked that question at one of the press conferences, and Sullivan did his usual "we can't give out more information" reply.
What we don't know is if an event where a lot of people gathered together and some were infected is defined as a cluster by the BCHD. Logic says it should be, but our local officials don't seem to follow logic. Same for an outbreak in a neighborhood. I'm absolutely certain there was one in College Station early on, due to the number of EMS calls to 5 or 6 difference addresses on one street over the course of 3-4 days; some addresses had more than one call for EMS. Almost every call was for "difficulty breathing or respiratory problems". Again, logic says it would be classified as a cluster, but they've never said what else they officially say is or is not.
One thing we know has not happened is a cluster, whether they define it that way or not, at a grocery store according to one of the earlier press conferences.
To me, "community spread" is when someone is infected, but they do not known when or where. They had no contact with a sick person, but clearly came into contact with someone while in public such as at the grocery store, doctor's office, or some other public location.
It seems now, given so many people are avoiding contact with others, going out only when needed, wearing masks (actual level of benefit of that is debatable), washing hands, etc. etc. etc. that cluster spread would account for most new cases.
"If you will not fight for right when you can easily win without blood shed; if you will not fight when your victory is sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves." - Sir Winston Churchill
