The latest data of the British medical and health service system shows that the system is currently facing the "triple threat" of COVID-19, flu and tight medical service resources, and may experience "the most challenging winter ever". The latest data released by the British NHS England Branch on the 24th showed that in the past week, there were an average of 344 flu patients hospitalized in England every day, more than 10 times the number of 31 at the beginning of December last year. Earlier, several clinical staff of the British National Health System pointed out that the service system was facing the "triple threat" of COVID-19, flu and the record demand for emergency medical services. Data shows that a large number of NHS employees were absent from work due to illness in the past week, and the main causes were COVID-19 and flu. Stephen Boyce, a senior official of the British National Health System, said in a statement that the staff of the medical system are facing considerable pressure, and the national health system is entering what may be "the most challenging winter in history". The British Academy of Pediatric Intensive Care said in a statement on the 24th that viral respiratory diseases usually lead to a surge in stress in the pediatric intensive care unit in winter. Epidemiological data show that the situation may be particularly severe this winter. In the past few weeks, the demand for pediatric intensive care beds in Britain has soared, and most pediatric intensive care units have reached or exceeded the capacity of beds. This situation may continue or even deteriorate in the coming months. The British Health and Safety Administration has previously issued a bulletin saying that there are strong signs that the UK may face a serious risk of large-scale influenza spread and COVID-19 epidemic this winter, and the public should be vaccinated with COVID-19 and influenza vaccines.
