% test data
cases = randi(100, 1, 5); % number of covid cases
names = { 'abc' 'def' 'ghi' 'jkl' 'mno' }; % country names
% organize data in cell array and sort
C = [num2cell(cases') names'];
C = sortrows(C, -1); % descending by number of cases
% cases on y axis, names on x axis
bar([C{:,1}]);
set(gca, 'xticklabels', C(:,2));

OK, good. I've modified the code to include sorting by number of covid cases in descending order.
