Sickness should not be visible to all employees in calendar

I want everyone to see when people are on Annual Leave but not on Sick Leave in the calendar.  I have set the system up so all teams have access to the calendar to see all teams and to see “Type of Leave Request” but not the “Leave Reason / Detail”.  However, everyone is able to see when people have been off sick which is not great for confidentiality.  Is it possible to only show normal Leave or Annual Leave rather than Sick Leave?  It’s not great if people can see how many days sick other people have had.
