All measures mandated on us to prevent covid-19 spreading are well and good. The authority should also look into the environment where it can be most conducive in spreading. May I humbly suggest that all public air-condition enclosed areas be sanitised by ‘filtering’ through sanitising lights or rays. It would be fantastic if someone can come out with a virus indicating MASK.

Poor ventilation inside closed air-cond is the main culprit. Must grow more green plants inside buildings to have oxygen.create more green parks for joggings. grow more trees.
