The fifth round of epidemic is close to the peak
As of January 15, 326 million cases of covid-19 had been confirmed worldwide, and the overall infection rate reached 4.18%; The total number of deaths was 5.544 million, and the mortality decreased slightly to 1.7%. Since the end of 2019, there have been five rounds of covid-19 epidemic in the world. The first round is from the end of 2019 to September 2020. Covid-19 epidemic has gradually spread from East Asia to the world; In the second round, from October 2020 to mid February 2021, the epidemic situation in Europe and the United States has seriously deteriorated due to unfavorable social customs and prevention and control; In the third round, from late February to mid June 2021, the virus mutation and traditional festivals led to the outbreak of the epidemic in India, and the epidemic in Europe and America was controlled with the help of vaccination; The fourth round was from late June to early October. The delta strain with strong infectivity and immune escape characteristics first found in India spread to the United States, Europe and Asia. The fifth round began in mid October, mainly in Europe and the United States to relax preventive measures after vaccination, while the newly discovered Omicron strain in South Africa has stronger infectivity and immune escape characteristics, superimposing the Festival gathering effect at the end of the year; Moreover, the continuous promotion of covid-19 epidemic vaccination and concerns about the pressure on the social medical system make most European and American countries reluctant to tighten epidemic prevention and isolation measures excessively. As of January 15, countries and regions with more than 20000 new confirmed cases per day include the United States (North America, 760073), France (Western Europe, 297019), India (South Asia, 211799), Italy (southern Europe, 181165), Spain (southern Europe, 132590), Britain (Western Europe, 117533), Argentina (South America, 113157), Turkey (Middle East, 69477), Brazil (South America, 68028) Germany (Central Europe, 63760), Portugal (southern Europe, 34182), Mexico (South America, 33628), the Netherlands (Western Europe, 33360), the Philippines (Southeast Asia, 33072), Canada (North America, 32230), Colombia (South America, 30207), Peru (South America, 29121), Switzerland (Central Europe, 26099) and Belgium (Western Europe, 25578), The global average daily number of confirmed cases was 2.798 million, far ahead of the number of newly confirmed cases in the most serious period of several rounds of epidemic. Given that the year-end aggregation effect subsides over time, we expect the peak of this round of epidemic to arrive in mid and late January, but its subsequent remission rate is relatively slow.
