Is disease prevention by the government a pure public good or a private good? explain

NO

Explanation:

Streetlight is an example of public good. When I get the light from a streetlight, another person can also get the light from the same streetlight at the same time. It is indivisible. It is difficult to exclude someone from getting the benefit of a street light. (A wall and toll gate are needed to exclude but these are costly). It is non-excludable.

In addition to public goods, governments may provide pipe water supply, electricity, medical care, higher education, etc. These are not public goods since each of these services is divisible and excludable.
