Doesn't spread by air from all current evidence. Spreads by saliva and nasal fluid droplets. In the churches in Singapore, it is thought that the spread happened from the congregation eating food from shared bowls after the service. Communion service in catholic churches is also a potential vector. There are two big church linked clusters in Singapore. Langar in Sikh gurdwaras are probably less risky because generally cutlery and plates are not shared but best to be cautious about shared/buffet type setups. Public transport is considered relatively safer in Singapore especially as cleaning has been steeped up. There's a story in Hong Kong about the whole big family getting it after sharing a traditional Chinese meal.
