Yifang Zhu mentioned in WRCB NBC 3 Chattanooga: COVID-19 death rate rises in counties with high air pollution, study says

“I think overall the general convolutions that long-term exposure to PM 2.5 increases the risk or COVID-19 deaths is probably generalizable to a global scale,” said Yifang Zhu, a professor in the department of environmental health and sciences at UCLA, who was not involved in the study.  “So, I think the study gives strong evidence to highlight the importance of further improving our air quality overall,” Zhu said.
