Ensuring basic health care for people in low-income countries is critical to the Plan B goal of eradicating poverty and stabilizing population.
While heart disease and cancer (largely the diseases of aging), obesity, and smoking dominate health concerns in industrial countries, in developing countries infectious diseases are the overriding health concern. Besides AIDS, the principal diseases of concern are diarrhea, respiratory illnesses, tuberculosis, malaria, and measles. Child mortality is high.
Progress in reaching the United Nations (U.N.) Millennium Development Goal of reducing child mortality two thirds by 2015 is lagging badly. As of 2005 only 32 of 147 developing countries are on track to reach this goal. In 23 countries child mortality has either remained unchanged or risen. And only 2 of the World Bank’s 35 fragile states are on track to meet this goal by 2015.

Health challenges are becoming more numerous as new infectious diseases such as SARS, West Nile virus, and avian flu emerge. In addition, the accumulation of chemical pollutants in the environment is starting to take a toll. While infectious diseases are fairly well understood, the health effects of many environmental pollutants are not yet known.
Among the leading infectious diseases, malaria claims more than 1 million lives each year, 89 percent of them in Africa. The number of people who suffer from it most of their lives is many times greater. Economist Jeffrey Sachs estimates that reduced worker productivity and other costs associated with malaria are cutting economic growth by a full percentage point in heavily affected countries.
Although diseases such as malaria and cholera exact a heavy toll, there is no recent precedent of a disease affecting as many people as the HIV epidemic does. To find anything similar to such a potentially devastating loss of life, we have to go back to the smallpox decimation of Native American communities in the sixteenth century or to the bubonic plague that took roughly a fourth of Europe’s population during the fourteenth century. HIV is an epidemic of epic proportions that, if not checked soon, could take more lives during this century than were claimed by all the wars of the last century.
