Hey there!

Public health policies and government regulations are the basis of good health and disease prevention fo the public. 

First of all, if we create public health policies and government regulations that allow people who possibly cannot afford their medications to get them for reduced price or free, we can increase the amount of people who have good health and aren’t prone to diseases.

Government regulations can also help people who are well off, too. If we put government regulations and policies in place promoting good health habits like washing your hands often even with the CDC, we would be able to show the public the benefits of good health.

Thus, using government regulations and health policies can help anyone and give support and reasons to the general public to maintain good health.

Hope this helps
