I agree that more training, not less is better. However all training should be incremental. At one time, as has been pointed out, WB was for experienced scouters. It was the highest level after having demonstrated skill at the other levels. The last few iterations are using WB as the introductory training. Which is ok, if it is marketed as such and there exists follow-up advanced trainings. However these do not exist.
Imagine a scouter training regimen which has levels and required trainings to be completed to advance in each level. They can be called whatever we wish, but for the reqs could be something like:
Scouter basic: YPT, troop committee training, patrol method module (which should be created)
Scouter 2nd class: basic plus SM specific, and IOLS.
later levels might have "options" like mB training, or safety afloat, or A-IOLS.
Cubbers could have a similar track.
While comparisons to stomach bugs and other illnesses may be helpful, it is important to note that diseases like measles seem to be very different.
1. People who have contracted measles are contagious for four days before symptoms appear; by contrast, patients infected with the flu are contagious for just one day before symptoms appear. Checking glands and temperatures upon arrival will not catch measles in advance; by the time infected people are found, others have already been exposed.
2. Unlike the flu, there is no "season" for diseases like measles. While it may spread faster in the cold months, the current outbreaks in Europe have flourished during summer.
3. While hygiene and sanitation play a key role in stomach bugs, flu, etc., they may not help as much with measles. Once an infected person leaves a room, the viral particles in the air may remain viable for up to two hours.
4. While the vast majority of people will recover from measles, there is a small risk of fatalities. There is also a small risk of permanent vision, heart or neurological problems. There is also a small risk of virus reactivation years after the initial occurrence; if this happens, it is always fatal and there is no treatment.
Camps probably have not had to deal with the likes of measles since the 1950s, so this is essentially new ground (outbreaks of mumps and whooping cough are also occurring). At this point, it is unlikely that BSA will require the immunizations that are currently recommended. Even if they were required, people could write in fake dates in the immunization sections of health forms (if the doctors left them blank).
So, camps, along with their state health departments, may need to consider a number of questions, the answers of which may vary, depending on the disease.
Should infected people go to the health lodge or should the health staff go to the infected people (perhaps, to minimize exposure to others)?
Should all people without vaccination for the disease in question be sent home, or just those with symptoms, or close proximity to the infected persons?
Should unvaccinated people be restricted from coming to camp during the following week of camp?
At what point would a camp be closed entirely and for how long?
