@Netherbury people who have had it in the last have an even greater risk and should be required to wear masks more than anyone. We have no idea if the virus has died within them, or if it has gone dormant. This is the biggest reason why a vaccine is being pushed, because we have no idea what will happen if it's dormant and reactivates in someone. It might come back stronger. Having people wear masks in businesses is only the slightest of inconveniences.
