In the general impression, infectious diseases are always accompanied by a sharp outbreak. A large number of pedestrians fell down, and the city turned into ghost towns in a blink of an eye, and every household closed their doors and doors appeared at the same time. Unfortunately, this kind of scene is not impossible to become a reality, but it is often only found in scripts written by Hollywood. If a few lively zombies can be added, the movie "Resident Evil" will be reproduced.

But infectious diseases that exist in reality, except for the biological weapons specially prepared by several superpowers, even the Japanese unit of the 731st in the human demon cave could not produce such powerful bacterial weapons. The infectious virus that truly poses the greatest threat to humans does not kill the infected person within a few hours, and the more toxic the better.

The Ebola virus, which is known to be the most severely infected among the infectious viruses, also takes several days of incubation, and the mortality rate cannot be too high at the beginning, otherwise the infected person will die soon on a large scale, and the virus has not yet been transmitted to the next host, or is discovered by medical staff, and isolate it early, and even the most fierce virus will lose its effect.

Even if a virus is about to break out, it can be infected through droplets and air. The total number of infections around the world is no more than 100,000, and only about 100 people die. It is already the most dangerous infectious disease in recent years. However, with the famous HIV and Ebola and other virus stars, compared with the most famous Spanish flu in history, the number of killings is nothing.

The Spanish flu is the most deadly infectious disease in human history. From 1918 to 1919, it caused about 1 billion people to be infected around the world, 25 million to 40 million people (the world population was about 1.7 billion at that time); its global average mortality rate was about 2.5%-5%. The origin of its name is not because the flu broke out from Spain, but because about 8 million people in Spain were infected at that time, and even the Spanish kings were infected with this disease, so it is called the Spanish-type influenza.

It actually broke out in the United States at the earliest, surrounding the region six times, and there were reports of the influenza epidemic on almost all continents. Because it was in World War I at that time, and the virus had very strange characteristics, the deaths of its infection were mostly young and middle-aged people, and the survival rate of the elderly and children was relatively high even if they were infected, which was very different from the general infectious disease. It even led to the early end of World War I because there was no enough soldiers to go to the battlefield! It was considered a major epidemic that made major changes to the world's political situation.

After the persistent research of later pathologists, more and more evidence shows that the Spanish flu is a branch of the influenza A, scientific name h1n1. Influenza A is the most likely cold that humans suffer from. No one in the world can survive. Influenza infected by ordinary people can heal itself by relying on the body's own immunity.

However, there are two other branches in Influenza A, which makes people shudder. The h1n1 virus belonging to the Spanish flu, which makes people feel scared, is called swine flu, and belongs to one of them. As for the other type, the h5n1 virus that makes East Asian countries frightened, commonly known as avian influenza.

Logically speaking, I also know that avian flu and swine flu were originally just cold viruses that spread in these two types of animals, and the cold virus infected by humans does not interfere with the river. However, humans’ delicious nature and modern large-scale mechanized breeding technology make these viruses prone to mutations. The Spanish flu pandemic that changes in swine flu has taught humans a vivid lesson.

In 1997, a crisis of avian influenza broke out in Hong Kong, killing more than 10 people, causing a lot of storms. Given the economic backwardness of Southeast Asia and the characteristics of various animals and humans living together, the World Health Organization issued an early warning to remind the local area of ​​avian influenza and the occurrence of avian influenza infection in humans.

Faced with the fierce influenza pandemic, countries are not unprepared. Many countries have their own influenza vaccine databases, but this is just a defensive measure. Once avian influenza and swine flu mutate, the originally targeted vaccine will be useless. At this time, the drug that can effectively fight influenza A has become the only life-saving straw.

Yang Xing takes advantage of the rebirth advantage and knows that this "life-saving medicine" will inevitably sell well when encountering the avian flu and swine flu epidemic, how could he let this gold mine go? Moreover, the pharmaceutical industry is different from other industries and has a counter-economic trend effect. The economic growth is not yet obvious. Once the economic crisis is in a depression, the pharmaceutical industry will be able to calm down and stabilize the company's stock price, and will rise against the market if necessary.

Because a person can live a life of sluggish food when he is in danger, but the disease cannot be stopped, which will kill people! Therefore, medical expenses will not be greatly reduced in any case. Moreover, during economic crises, people's morale is depressed and they are more likely to get sick. In previous economic crises, the performance of pharmaceutical companies has increased instead of falling, so some people ridiculed pharmaceutical companies and coffin shops as unscrupulous businessmen.

Of course, Yang Xing ignored this mean comment. He always advocated that he would either not do something, and that he should do it to the best. Given the benefits of Duffy, he had tried every means to obtain the authorization of Swiss Roche Pharmaceuticals to produce this medicine at home. For this reason, he guided Wang Yunqi to acquire several companies engaged in the production of shikimic acid in Chang'an, the capital of Lingxi Province, and has become the world's number one company in the production of this pharmaceutical raw material.

The new drug, Duffy, was launched in 1999. Its main ingredient is shikiic acid. This unfamiliar material actually comes from the traditional Chinese spice - star anise. This is a fruit of a plant grown in southern China. It has a unique fragrance after drying. In addition to being a traditional Chinese herbal medicine, it is mainly used as a ingredient in domestic braised materials. At this time, few people know that it is actually one of the main synthetic raw materials of Duffy.

Because the shiki acid extracted from star anise is single use and has been indifferent. Chang'an, China is its main production site. Yang Xing visited Chang'an last time and helped Wang Yunqi integrate the shiki acid production enterprises there. Now the raw materials and processing enterprises of shiki acid production are in the hands of Yunhai Pharmaceutical, and Wang Yunqi's negotiations with Luoche Pharmaceuticals are full of confidence and will not give up until the goal is achieved.

Yang Xing, the number one traitor, set up a Hongmen Banquet, and used the Swiss castle as a negotiation venue to suppress the momentum of the Roche Pharmaceutical's negotiation team. Although Yunhai Pharmaceutical is not well-known overseas, it holds the ace of shiki acid. In addition, Duffy has not yet reached the point where it is difficult to find a drug later, so Wang Yunqi quickly took the initiative in the negotiation. Finally, the two sides reached an agreement and agreed that Yunhai Pharmaceutical share Duffy's patent by paying fees and was authorized to produce the drug at home.
