Can my kids keep going to their martial arts classes during the covid-19 pandemic? is it safe?

Would not recommend : Martial arts classes generally involve being close to one another and the instructor being even closer. There are also generally mats which everyone is touching and breathing on and would be difficult to disinfect during a class. Depending on where you live, you may be in a different stage of physical distancing by law, but this type of school is not open in most places. Look for virtual classes!
