    "Now the global epidemic is at a critical moment, and regions outside China have become the biggest concern." This is a statement made by World Health Organization director general Tan Desai at a press conference in Geneva on February 27Novel coronavirus pneumonia occurred in 3474 out of 44 countries outside China and 6 died in Geneva at 6 am as of 27 amThe novel coronavirus pneumonia originated in Wuhan, China, eventually broke through the defense line and spread to the world< br / > at the same time, Wuhan, a big city with more than 10 million people, has been closed for more than a monthThe bustling city of the past has become a cold empty cityThe decision to seal the city was not easyIt was called the first time in human history to block a megacity with a population of ten million in peacetime< br / > in the 21st century, the modern medical system is more perfectHuman beings can effectively control the known infectious diseases, but the virus is still so easy to destroy a city or even a countryThe reason is that at present, the global population has reached 7.8 billion, the cluster of super large cities are everywhere, the development of transportation and the rapid acceleration of globalization provide a channel to accelerate the circulation of the virus, and also provide a hotbed for virus mutation and infection, while the state, government, medical treatment and science have not evolved a virus prevention and control system suitable for the social systemMoreover, in the face of the virus, a cunning and fierce enemy, human beings have almost never won< br / > at the same time that Wuhan was closed, the documentary "epidemic: how to prevent influenza outbreak" was launched on Netflix"The question is not whether it will happen, but when it will happen." The gloomy prediction of documentary has become a reality at presentVirus, which is almost as old as the earth, is between "life" and "non life"It has been searching for a host and replicating itself all its lifeEvery once in a while, the virus will sweep the world, bringing a catastrophe to mankind, from the oldest Black Death and cholera in Europe to the flu, Middle East respiratory syndrome, Ebola and SARS in the past 100 years < br / > although it is not easy to say that it is a victory, human beings have also achieved brilliant results in the prevention and control of infectious diseases: the black death in Europe broke people's worship of God, promoted the Renaissance and the arrival of the industrial era; the Spanish influenza in 1918 promoted the establishment of the modern medical system in the United States, and advanced science and diagnosis and treatment technologies such as the vaccine have also been developing, Cholera, plague, smallpox and other diseases have been successfully eliminated, and various countries have gradually established a public health defense system against infectious diseasesAt a certain level, the virus has changed the global political, cultural, medical and scientific trends< br / > Who has repeatedly stressedThis is the phased achievement of human beings - to recognize the strength of the enemy, and once such a consensus is reached, the intelligent human beings will win the final victory with their strong brains and execution< br / > it is necessary for us to review the major epidemic events that have changed the society in human history, learn from them, and find the password to stop the epidemicThis code is not only about medical prescriptions, but also about reflection on education, behavior, culture and politicsAt the beginning of the 20th century, the sharp decline of the world population was not caused by the first World War, but by the virusA pandemic influenza spread to the world with the pace of the war, causing 500 million people to be infected and 40 million to 100 million people to dieAt that time, the total population of the world was only 1.7 billion< br / > on Monday, March 11, 1918, the new recruits training camp in Fenton, Kansas, USA, was on fire to train new recruits and prepare them for the European battlefieldAt the back, a company chef, private gitchel, complained to the nurse that he was "cold, sore throat, headache and sore muscles."The chef became the "patient zero" of the Spanish pandemic that spread to the world< br / > from gitchel, the spread of the virus to the entire military camp beganRecruits can enjoy a five-day holiday after three months of trainingThis holiday mechanism has spread the virus throughout the United StatesAt the end of April, 30 of the 50 major cities in the United States found flu casesBut these did not cause any concern, just a cold, soldiers but to fight in the battlefield< br / > the virus is rampant and spreads in human beings 84000 U.S troops were shipped to France to participate in World War I in April, the influenza virus spread rapidly in the British and French barracks on the European continent In June, the influenza began to break out in the German army At that time, the British and French soldiers recovered and recovered their fighting capacity, defeated the German resistance at one stroke, and officially opened the prelude to the demise of the German army < br / > World War I is over in the hands of the invisible operation of the virus, but the flu is far from over In August, there was a mutation in influenza, starting in France and the United States until the global outbreak In Philadelphia, U.S., public health chief Crusoe turned a deaf ear to the attack on the barracks He was preparing to hold the largest parade in Philadelphia's history The March, which has been planned for several weeks to sell millions of dollars of war bonds, will involve thousands of people and hundreds of thousands of onlookers Although Crusoe felt the strong pressure of people to cancel the March, the headline of the newspaper carried a good news, which led to the progress of identification of influenza pathogens, and the work of developing serum and vaccine could be started What the paper didn't say was that scientists were not sure about the discovery Crusoe assured the marchers that there would be no danger, so the Philadelphia free bond parade, attended by hundreds of thousands of people, began as scheduled < br / > the March is seen as an important boost to the global outbreak of influenza Before the March, the flu mainly spread among the barracks and sailors Within 72 hours after the March, 31 hospitals in the city were full of beds In just 10 days, the epidemic has developed from hundreds of diseases and only one or two deaths per day to thousands of diseases and hundreds of deaths per day < br / > we can no longer estimate how many deaths are caused by lies John M Barry wrote in the great flu: the epic of the deadliest plague In 1918, the war was the main topic at that time, and stabilizing the army was the priority of the government They were worried about taking any action that would cause panic So authorities swore to the newspaper that it was just a common flu All the participating countries, including the United States, France and Germany, had strict news control and were not allowed to render the regional flu as a "plague" Throughout Europe, only the media of Spain, the neutral country, is not regulated Every day, they report their own influenza situation Eight million Spaniards are infected with the flu, even King Alfonso III The global media also follow up quickly Under the overwhelming reports, Spain seems to be a hell on earth That's why the flu is called "Spanish flu." In order to get rid of this stigmatized name, the Spanish argued for a hundred years < br / > in March 1920, the last case of Spanish influenza was recorded According to a later study by the CDC, this is a virus originated in the permafrost of Alaska It broke through the cage and spread all over the world, then quickly disappeared After decades of silence, after evolution and recombination, in 2009, the virus returned to the world in a new form Scientists named it "H1N1" < br / > the virus becomes more cunning Before it makes a comeback, it makes a test in human beings As early as 1976, an Army recruit in Fort Dix, New Jersey, was infected with the flu virus Genetically, this is a 1918 strain of influenza virus The U.S government made the worst plan, ordered a massive immunization program, and vaccinated up to 40 million people across the country It turned out that this was a false alarm After 200 people were infected and one died, the virus mysteriously disappeared again However, many adverse reactions occurred in vaccinated people, and 25 people died < br / > when the re mutated H1N1 virus reappeared in March 2009, the U.S government, drawing on the experience of 1976, characterized it as "moderate" and believed that the disaster had not yet occurred The outbreak of large-scale epidemic is sudden and unpredictable, which determines that the government should consider more social and economic impacts besides public security Although the who has raised the alert to level 5 at this time, the CDC has repeatedly stressed that the global pandemic is close < br / > at the end of the holiday in the United States in late August, a large number of students returned to school The H1N1 virus, regarded as "mild", exposed its killer nature The epidemic situation in the United States accelerated and the number of deaths increased rapidly Many experts began to reflect, and the media once again reported that the who raised the warning to the highest level of 6, and the panic hit the United States again On October 23, after months of deliberation, then President Barack Obama finally pressed the national emergency button, half a year after the outbreak The CDC estimates that millions of people have been infected, at least 20000 hospitalized and 1000 dead by this time < br / > by 2020, the latest influenza data released by CDC shows that the new H1N1 virus has been included in the list of common influenza, and people are no longer unfamiliar with it, and have mature experience in dealing with it A bronze statue of Edgar, a five-year-old boy who was the first to be tested for H1N1 before the 2009 U.S pandemic, stands on the mountain of Mexico < br / > 02 the help of SARS < br / > Hegel said: "the only lesson we have learned from history is that we have never learned from history." Novel coronavirus pneumonia sadly sigh again when the new crown pneumonia outbreak occurred in 2020 Perhaps in the spring of 2003, people who experienced the SARS epidemic also sighed like this < br / > on December 10, 2003, Huang xingchu, 36, who was a chef in a hotel in Shenzhen, was admitted to the General Hospital of Guangzhou Military Region He had fever, weakness, nausea and other symptoms two weeks before he was sent to the hospital He was treated as a cold in the local people's Hospital of Heyuan City and the treatment was ineffective for a period of time When he came to the General Hospital of Guangzhou Military Region, Huang xingchu had a high fever for 7 days, and his whole body was purple < br / > on December 17, a message came from Heyuan people's Hospital, which showed the same symptoms with 11 medical staff Huang xingchu had contacted Heyuan people's hospital quickly reported the message to the Department of health of Guangdong Province Guangdong Provincial Department of health quickly began to sample, but by this time the pathogen could not be separated < br / > Spring Festival is the most important festival in China and the largest seasonal population flow frenzy in the world Guangdong is the participant of this frenzy Despite the rumors in Guangdong, the government was worried about the response of the public and did not give timely feedback, which led to the Spring Festival in 2003 becoming a viral craze On the eve of new year's Eve in 2003, Zhou Mou, a patient who was later called "poison king", was admitted to Zhongshan Third Hospital in Guangzhou After six hours of rescue, the patient was finally out of danger However, the shadow of pneumonia shrouded all the medical staff involved in the treatment In the Third Hospital of Zhongshan, Zhou infected two groups of more than 50 medical staff and more than 20 relatives and friends < br / > on the 12th floor of Lingnan building, Zhongshan No.2 Hospital, where Zhou lived, Liu, a 64 year old professor of Nephrology, started to have a low fever and cough in the middle of February He thought he was just a common cold according to the judgment of the doctor On February 21, he and his family went to Hong Kong to attend the wedding of his sister and children In the afternoon of the same day, I checked into the Jinghua international hotel That night, I had a high fever, coughing, sneezing and vomiting in the corridor on the 9th floor The 9th floor corridor of Jinghua international has become a super infectious source for spreading virus to the world <
