As we head into fall and then winter, we're heading into the height of the flu season. It's one of the functions of a public health system to monitor the trends and signal the dangers of communicable diseases such as the whooping cough outbreak across the country, for which information and public awareness campaigns are being run. Another function is to monitor and inform regarding any seasonal issues affecting health. It's important to understand that none of us live in a vacuum, and the public health system is one way to try to protect us from ourselves and one another in terms of health concerns.
Public health should work to make certain that the public is safe from any health concerns. As mentioned above it should work with sanitation to help prevent disease, offer vaccinations to prevent illness and provide information to the public to keep themselves healthy.
It should be free and accessible to all.
Public health is the function concerned with maintaining and improving the general health of public, that is people of a community. This includes services like
prevention and control of disease by providing proper sanitation, conducting immunization programmes, enforcing quarantine regulations, and providing health education for individuals, groups, and organizations. Provision of clean water and good sewage collection and disposal system are also important aspect of public health function.
In most of the countries government undertakes various programmes to provide public health services to its people. Voluntary organizations also play a major role in providing such services.
