Cost/need: The diseases you list cannot be cured & are not likely to cause death, female sterility and or brain damage if unrecognized. The basic package are those considered most common,worrisome & treatable. The package also does not include the 9+strains of HPV that infect the genitals. Cost,effect & ability to treat guide the development of "screening" tests.
