Chatham-Kent's Medical Officer of Health is concerned there might be a spike in cases of COVID-19 following the Black Lives Matter march in Chatham.
It's estimated that upwards of 2,000 people took part in the march Friday night from the WISH Centre down King Street to the Civic Centre.
Dr. David Colby said they worked with the organizers of the march to try to make sure everyone followed physical distancing and wore masks.
"We were assured that that would be followed very, very strictly. And the pictures that I have seen with regard to the Chatham event, that does not appear to be the case."
However, they won't know right away if the march will lead to a spike in cases.
"If there were any cases there that were contagious, then we could see a large number of people that end up getting this," said Dr. Colby. "I really hope this is not the case, but we won't know for a week or two whether that happens."
If you did attend the march, Dr. Colby said there are some things you should do.
"Self-monitor, and if you start feeling unwell, by all means, get a test. It's quick and simple, and get people checked out that way."
