Mayor Bill de Blasio is warning New Yorkers about what he says is a worrisome trend with the coronavirus. 

The mayor says that people between the ages of 20 and 29 are seeing an increase in infection rate. 

De Blasio says that it has been an incredibly difficult time for young people, between being cooped up and not being able to see loved ones. But he says that now is not the time to become lax when it comes to social distancing or wearing a mask. 

He warns that the biggest increase is those between the ages of 20 and 30 but that there is also an increase in cases for those 30 to 40 years old. 

It comes as the numbers in other parts of the country are starting to soar. 

Dr. Rossi A. Hassas, an epidemiologist, says that even though cases are rising among young people, it’s not a huge number since positive cases in New Yorkers are relatively low. 

However, he says there may be harm in young people bringing it home to their older loved ones.

Dr. Hassad says he agrees with the mayor and says that young people need to continue to wear a mask, because it is working. 

The mayor says they will also be working hard to reach younger people about staying safe and getting tested.
