{
    "issue": "Data consistency and completeness for 'ConfirmedIndianNational' and 'ConfirmedForeignNational'",
    "evidence": "ConfirmedIndianNational     False\nConfirmedForeignNational    False\ndtype: bool,\n    ConfirmedIndianNational ConfirmedForeignNational\n473                       -                        -\n474                       -                        -\n475                       -                        -\n476                       -                        -\n477                       -                        -",
    "description": "The columns 'ConfirmedIndianNational' and 'ConfirmedForeignNational' contain '-' instead of actual numerical data or 'NaN' values indicating missing information starting from records after '29/03/20'. This indicates a potential issue with data collection or data entry protocols where data for Indian and foreign nationals confirmed cases has not been recorded or is marked as '-', affecting the dataset's consistency and completeness."
