Episodes of dengue can cause catastrophic health costs for households
In a 2002 study from Cambodia, households with a dengue patient had to borrow money at high interest rates and lose productive assets (land) to repay debts linked to healthcare costs. Public healthcare cost significantly less than private healthcare but was either not present where people lived or did not have a good reputation.

Vaccines are most cost-effective in low income countries
An analysis of the impact of rotavirus vaccine in 25 countries found that the rates of vaccination in all countries were highest and risk mortality lowest in the top two wealth quintile’s coverage. Countries differed in the relative inequities in these two underlying variables. Cost per DALYs averted in substantially greater in the higher quintiles. In all countries, the greatest potential vaccine benefit was in the poorest quintiles; however, reduced vaccination coverage lowered the projected vaccine benefit.
