In developing areas around the globe it is extremely hard for health related institutions and governments to implement
prevention and treatment policies, to improve public health, due to poor economical resources and infrastructures; low
awareness; inadequate personnel; high prevalence of parasites and pathogens with extreme infection burdens, as well as
Central government programs essential for the improvement of the general public health are limited in developing countries.
These include mass vaccination programs, which are cornerstones of primary health-care ; programs to reduce waterborne
and water-associated vector-borne diseases ; routine surveillance activities [3,4]; regulation of pesticide usage (e.g.
developing countries use only 20% of the world's agrochemicals, yet they suffer 99% of deaths from pesticide poisoning );
programs to reduce malnutrition ; programs to educate the public (e.g. use of condoms to reduce sexually transmitted
diseases); and funding of medical care.
