The country spent big on quarantine and testing facilities over the past three years rather than bolstering hospitals and clinics and training medical staff, these people said. "There is no transition time for the medical system to prepare for this," said Zuofeng Zhang, professor of epidemiology at the University of California, Los Angeles. The failure to boost vaccination rates among the vulnerable could imperil China's health system, more than a dozen experts said. The death of a 23-year-old medical student in Chengdu on Dec. 14 fueled public ire at the strain on China's health system. Chen Jiming, a researcher at China's Foshan University, said there was every chance that China's medical system could cope now that the country has ended quarantine for asymptomatic and mild cases.
