While only smallpox has been completely eradicated as a cause of human diseases, there are 10 other diseases on their way out. These diseases include those caused by polio, measles, and hepatitis B viruses, as well as maternal/neonatal tetanus. Preventive treatments are available but proper financing will be required. In order to eradicate polio by 2005, approximately $1 billion is needed to remove pockets of infection in 20-30 countries. Measles could be eliminated by 2010 at a (today’s) cost of $3 billion. To achieve elimination of hepatitis B virus infection by 2010-2015 will cost between $3 billion to $5 billion. Controlling maternal/neonatal tetanus disease by 2005 is possible with an additional sum of $130 million in aid.
