PUZZLE NO. 45 : KILLER/LITTLE KILLER HYBRID

Another sudoku on COVID-19 theme. This time , a hybrid of killer & little killer. This sudoku gave me the maximum satisfaction of all the sudokus that I have made till now. First , the cages are in the shape of COVID. Secondly , the little killer clues are all 19. Thirdly , if you notice the sum of the cages that make up each letter of COVID , they are all related to 19. For example , the cages the make up C add up to 19 . O is made up of four cages . Two of the cages add up to 19 and the remaining two also add up to 19 . The cages the make up V , also add up to 19. The numbers in the cage denoting I add up to 19. The cages that denote D add up to 38 , which is twice of 19. It really took up a lot of effort to get this done. Hope you people will like it.

RULES : Classic sudoku rules apply. Additionally , there are some cages in the grid. The number on the top left corner of each cage is equal to the sum of the numbers in that cage.
