在美国,用于流感的费用是很高的。据保守估计,平均每年的费用达10亿美元以上,而实际费用很可能是30—50亿元。这祥计算是把因流感造成的开支都加在一起。流感病人接受医疗服务的一切费用为流感的直接费用,如医生的检查、实验室的化验、处方用药和非处方用药、专门设备等费用。但这些费用仅占总费用的20—30％。 In the United States, the cost of influenza is high. According to conservative estimates, the average annual cost is more than one billion US dollars, and the actual cost is likely to be 3 to 5 billion yuan. This calculation adds all the expenses caused by the flu. All costs for influenza patients receiving medical services are the direct costs of flu, such as doctor’s checks, laboratory tests, prescription and over-the-counter medications, and specialized equipment. However, these costs only account for 20-30% of the total cost.
