HALIFAX -- Several recent COVID-19 cases in Nova Scotia have no clear link to travel or a known COVID case. That has the province’s top doctor concerned about community spread and the fact many people who recently tested positive have been socializing more. "We have to end up with the conclusion that quite likely we're seeing some early signs of community spread," said Dr. Robert Strang, the province's chief medical officer of health. "Our case numbers are going up, the numbers that we don't have a clear explanation in is growing." Strang says recent COVID-19 cases have concerned him after learning the individuals have had very active social lives, and tend to go out multiple times per week.
