Any qualified voter whose physical disability which confines him or her to a hospital or causes him or her to be confined to bed and prevents or will prevent him or her from being present and personally voting at the polls on any election day in the city for city elections shall be considered an absentee voter.

Such certificate shall be filed with the board of supervisors of elections not later than seven (7) days prior to any city election. Thereupon, the board of supervisors of elections shall mail to the voter entitled thereto an absentee ballot. In all other respects, absentee voting as provided for in this section shall be similar to and controlled by the applicable procedure provided in this ordinance in the case of absentee voting.
