China's hospitals are already under so much pressure, following the country's rapid 180-degree shift in Covid policy that doctors and nurses could be infecting patients. It seems frontline medical workers are being told to come in even if they have the virus themselves because of staff shortages. A Chinese professor specialising in health policy has been monitoring the crisis in his home country from Yale University in the United States. Chen Xi told the BBC that he has been speaking to hospital directors and other medical staff in China about the massive strains on the system right now. "People who've been infected have been required to work in the hospitals which creates a transmission environment there," he said. China's hospitals have hastily increased their fever ward capacity to meet a huge influx of patients, but these have been filling up quickly, in part because the message is still getting through that it is all right to stay at home if you catch the virus. Prof Chen says much more needs to be done to explain this to people. "There is no culture of staying at home for minor symptoms," he said. "When people feel sick they all go to hospitals, which may easily crash the healthcare system." A rush on pharmacies has led to significant nationwide shortages of medicine used to treat a cold or the flu. Home testing kits for Covid-19 are also hard to come by. In Beijing, though restaurants are allowed to open again, they have very few customers and the streets are quiet. Companies are telling employees they should return to the office, but many don't want to. This all makes sense when you consider that, just weeks ago, the government was saying that there will be no swerving from zero-Covid, that those infected must go to centralised quarantine facilities and that lockdowns were necessary. The coronavirus was something to fear and Chinese people were lucky to live here because the Communist Party would not sacrifice them on the altar of opening up. Now the goal of returning each outbreak to zero cases has been abandoned, Covid-19 is spreading like wildfire and the line from the government is that catching this disease is not something to worry about. China's easing of Covid restrictions was expected to unfold more slowly, much more gradually. Then came street protests, in city after city, with demonstrators demanding their old lives back. They wanted to be free to move around again. There were clashes with police and the chant was going up for China's leader Xi Jinping to resign and for the Communist Party to give up power. This was the straw that broke zero-Covid's back. According to Prof Chen, this meant that the timing of China's re-opening was "not ideal" but they had to do it. He said countries like Singapore and New Zealand made their changes when infections were at bay. However, China has moved with full-blown outbreaks under way in cities like Beijing. The government "heard the voice of the protesters", he said, but added that this was not the ideal choice for them in terms of timing. So the protesters may have won, but the speed of the cave-in from the government has left elderly people afraid to leave their homes. One woman we met going for a walk with her grandson said she would stay clear of crowded places, that she would keep wearing a mask and continue to wash her hands regularly. Yet a reluctance to be in places where infection is more likely permeates all groups in society. The impact on Beijing has been great. Another reason restaurants are empty is that the city government still requires a negative PCR test result within 48 hours to dine inside. However, the majority of results are not coming through to health code phone apps.
