In Am J Trop Med Hyg 87: 796–805 by Shepard and others, the authors recently uncovered a labeling error. In columns 3 and 6 of Table 5, on page 801 of this article, they endeavored to report direct costs per ambulatory and hospitalized dengue case. The numbers presented actually corresponded to the costs per outpatient visit and per bed-day, respectively. Due to that error, their subsequent calculations were also incorrect. Applying the methods in the article with the appropriate data, the corrected version of Table 5 is:
Table 5 (corrected).

EF = expansion factor.
The unit cost of death reported is the average cost; the actual values were estimated on the basis of the age distribution of reported deaths caused by dengue in 2009 (Ministry of Health Malaysia, unpublished data.
The range corresponds to the 95% certainty levels (centered on the median) in our projections, and is given by the simultaneous variation of parameters as indicated in Table 3.
As a result of the labeling error, the article mistakenly reported an economic burden of dengue illness of US$56 million or approximately US$2.03 per capita. The correction doubled the result. The corrected estimate of the economic burden of dengue illness in Malaysia is US$102 (95% CI: 78–311) million per year (MYR 359.79 million), approximately US$3.72 (MYR 13.08) per capita.
In Am J Trop Med Hyg 87: 883 by Salant and others, the word “granulosus” was misspelled in the title of the paper. The journal regrets this error.
