Soon the new semester will begin.

In March, Li Tianran saw SARS-related news when he went online, Li Tianran experienced SARS in junior high school, but completely forgot the specific year.

Because the epidemic areas at that time were mainly Beijing and Guangdong, there were no cases in the city where Li Tianran was located, Li Tianran did not have a computer at home at that time, and he usually did not watch the news, so he did not know much about the SARS incident.

I only remember that at that time, citizens all over the country were crazy to grab white vinegar, banlan root, and salt, which led to the price of these commodities rising.

There is no shortage of white vinegar and salt in the supermarket, although Banlangen is useless for SARS, and there are no cases in Dongying, Li Tianran still went to buy a few boxes of Banlangen with anti-inflammatory and preventive left and right after seeing the news.

Although it is useless, it is at home, it will still bring a sense of security to the family, and it will not be wasted, so you can drink it if you have a cold.

Li Tianran told her mother Zhao Yue the news again, and asked her to buy more white vinegar, salt, and disinfectant......

In the case of SARS, although Li Tianran was a reborn, it was a pity that because he didn't have a deep memory of this incident and didn't know much, he couldn't help much, at most he could only help refute the rumors when he saw them on the Internet.

For China's disasters in recent years, Li Tianran only remembers the 5.12 Wenchuan earthquake in 2008, when Li Tianran was about to take the college entrance examination, and the school played a 30-minute news broadcast every night for everyone to learn about current affairs and politics, so Li Tianran remembered it very clearly.

In order to express condolences, the State Council also designated three consecutive days from May 19 to May 21 as a national day of mourning.

Li Tianran still clearly remembers that at 14:28 on the afternoon of May 19, the whole class stood up, the air defense sirens sounded, the car horns sounded, and the people of the whole country observed a three-minute silence.

At that time, Li Tianran also prayed, praying for world peace, no disasters, and not so many injured people.

Because of this big event, Li Tianran doesn't remember the essay topic of the high school entrance examination, but he remembers the essay topic of the college entrance examination, "The grass comes from green in spring", and Li Tianran wrote that it will be rebuilt and restored after the earthquake, just like the grass in spring.

The Wenchuan earthquake was so tragic that many compatriots died. For the disaster in Wenchuan, Li Tianran has already thought of a series of plans, and will give early warning when the time comes.

Soon, SARS news reports began to increase, and everyone knew the name SARS, a respiratory infectious disease that can make you have difficulty breathing, fever, body aches, weakness and even death.

Rumors were spread everywhere that vinegar and banyan root could increase resistance, and everyone began to rush like crazy.

Mother Zhao Yue put a batch of white vinegar wholesaled in advance in the supermarket, and told everyone that there was no need to grab the rumors, and set a purchase limit, and each person could not buy more than 2 bottles.

Because others have raised the price but her mother Zhao Yue has not raised the price, the small supermarket of Li Tianran's family, the already good reputation has become better......

On April 20, 2003, a number of colleges and universities in Beijing announced the closure of classes, and on April 23, Beijing announced that the city's primary and secondary schools would be suspended for two weeks from the 24th to ensure that the epidemic would not spread on campus.

On the same day, the WHO released the latest statistics: as of the 23rd, the total number of patients with atypical pneumonia in the world was 4,288 (including recovered and some suspected patients), and 251 patients died, with a cumulative mortality rate of 5.85%.

The state has invested a lot of manpower, material and financial resources for this purpose, and the China Research Institute has begun to work hard to develop SARS vaccines.

Jian Huaijin has suspended classes in Beijing, and asked Li Tianran if he has suspended classes!

Li Tianran's No. 12 Middle School did not suspend classes because there were no cases in Dongying.

But the school also started the epidemic prevention work, spraying 84 disinfectant water every day, and sent a list to each student, recording the body temperature every day, and the students took turns to bring vinegar and put it on the radiator in the classroom to smoke, and the classroom smelled of vinegar every day......

Slowly summer is coming, the climate is warming, and the SARS virus dies quickly in a high temperature and high humidity environment, coupled with various emergency and effective measures of the government, strong regulation and control, SARS did not break out in a large area, but was controlled, and finally disappeared......

Li Tianran saw news on the Internet that the SARS vaccine was studied in about half a year.

It's just that the vaccine has only gone through the first phase of clinical trials, because there are no SARS patients in the follow-up, so the second and third phase clinical trials have not been carried out, and the vaccine will naturally not be able to be done, and the final vaccine will not be marketed.
