Chikungunya in Brazil: An epidemic of high cost for private healthcare, 2017.

Objective: We evaluated the impact of direct and indirect medical costs incurred through chikungunya infections in patients treated in Fortaleza, Brazil.

Methods: Cross-sectional study about the cost of illness. The valuation method of medical costs was based on the micro-costing approach (bottom-up). The study was carried out in a large general hospital of the private health network. The study population consisted of patients treated as suspected cases of chikungunya and hospital professionals who applied for sick leave due to chikungunya.

Results: In 2017, there were 2683 patients treated at this hospital who incurred an estimated cost of $383,514.40. From this amount, $174,322.91 (45.5%) were expended on emergency care, $194,700.59 (50.8%) on hospitalisations. 123 hospital professionals were infected with chikungunya and sick leave duration ranged between 1 and 19 days. Health professionals generated 746 days of absence and an amount of $14,490.90 due to absenteeism from work related to chikungunya. 31 symptoms were reported, especially arthralgia (91.1%) and fever (79.4%). There was a predominance of females (58.8%) and the age group of 20-39 years (42.1%).

Conclusion: The average cost of admissions was over $2400. Considering the epidemic potential of chikungunya, our data indicate the huge economic burden of this disease to healthcare units in the presence of epidemics. Economic factors, added to the loss of life and the consequences of chronic chikungunya, make this disease a real scourge for countries with fewer material resources.
