We used 2008 DHS data sets to construct child height- and weight-for-age Z-scores and used regression analysis to analyze the effects of different sources of drinking water and sanitation on child health outcomes in Nigeria. We also calculated the probability of a child being stunted or underweight as our measure of malnutrition among children aged 0–59 months.

This paper analyses differences in the choice of health care facility by ill individuals in HIV/AIDS-affected households in the Free State province of South Africa.

Previous studies have shown that cost of illness (COI) measures are lower than
the conceptually correct willingness-to-pay (WTP) measure of the economic
benefits of disease prevention. We compare COI with stated preference estimates
of WTP associated with shigellosis in a rural area of China. COI data were
collected through face-to-face interviews at 7 and 14 days after cultureconfirmed
diagnosis. WTP to avoid an episode similar to the one the respondent
just experienced was elicited using a sliding-scale payment card.

This article considers the investment case for using the Vi polysaccharide vaccine in developing countries
from two perspectives: reducing typhoid cases and limiting new health care spending. A case study is
presented using data fromSouth and Southeast Asia. The purpose of the paper, however, is to drawbroad
implications that may apply to developing countries in general. Typical consumer demand functions
developed from stated preference household surveys in South and Southeast Asia are used to predict

Many economic analyses of immunization programmes focus on the benefits in terms of public-sector
cost savings, but do not incorporate estimates of the private cost savings that individuals receive from
vaccination. This paper considers the implications of Bahl et al.'s cost-of-illness estimates for typhoid
immunization policy by examining how community-level incidence estimates and information on distribution
of costs of illness among patients and the public-health sector can be used in the economic
