My government just put the entire country under lockdown for the next month so I guess it will be way more than 1-3 weeks ( considering it has already been 1 month of partial lockdown )
I guess we never know when everything will be back normal, but it will be fine soon after the government can handle the situations. Many countries have been lockdown for 1 month or more because they don't want to see more infected people by the virus. But addicted people can still play gambling because of they an addicted person in gambling which is difficult to get a cure. Maybe some gamblers can get treatment by visiting some professional to get help. And if they can do that, they will feel happy because they can solve the addicting problem.
