One possible factor, according to a research team she's working with: the places where Filipino nurses are more likely to work.
"The major finding...was that Philippine-trained nurses were disproportionately in the ICUs, the emergency rooms, in long-term care facilities such as nursing homes, compared to White, US-trained nurses. They were therefore much more exposed to Covid-19," says Jennifer Nazareno, the co-founder and co-director of the
Philippine Health Initiative for Research, Service, and Training at Brown University's School of Public Health.
They're also more likely to live in multi-generational households, caring for more dependents. And often, she says, they're breadwinners supporting family members in the United States and the Philippines. That means they may be more likely to stay in high-stress jobs that put them more at risk.
