    ]

The given Twitter post does not relate to a maintenance report feedback for a public flat house. The post mentions Changi Airport, which is a physical location, and "virus" which is a general term for a disease-causing agent, but it does not mention any specific issue or problem related to maintenance or infrastructure of a public flat house. Therefore, the post does not fit into any of the categories mentioned in the question.
