In 1990, two persons--one each in California and Florida--were diagnosed with malaria classified as cryptic; their infections may have been acquired in the United States through bites of mosquitoes that became infected after biting parasitemic migrant workers.
1990年,有两人——加利福尼亚州和佛罗里达州各有一人——被诊断感染了一种被归类为隐匿性的疟疾;他们的感染可能是在美国境内被感染疟原虫的流动工人叮咬后受感染的蚊子叮咬所致。
