Death and the Afterlife.Buddhists believe that those who die are reborn in a form that is appropriate to the amount of merit they accumulated while alive.

Medicine and Health Care

The health of the population has improved over the last few decades, with increased life expectancy and lower rates of major diseases. An exception to this trend is the AIDS epidemic. The spread of AIDS is related to both sexual practices and narcotics use. The government has devoted substantial resources toward AIDS education and awareness programs and AIDS-related research.

Buddhist monks walk down a street in Thailand. Most young men become Buddhist novices. The health infrastructure includes facilities and programs provided by the public sector, nongovernmental organizations, and the private sector. The majority of health resources are concentrated in urban areas, where a marked difference in access to health facilities depends on wealth. Private sector facilities exist almost exclusively in urban areas. Public health facilities in rural areas include district hospitals and community health centers. In small towns and villages, health care is provided mainly by village health communicators and village health volunteers who receive little training. In urban areas, private hospitals are becoming important providers for the wealthy and the middle class. In the 1990s, the government adopted a policy of self-reliance that included greater attention to classical traditional medicine and herbal folk medicine.
