It is now the second half of the year, and the Chinese New Year is just a few months away.

As soon as the unknown infectious disease appeared, researchers from many places went to Guan County for investigation and research in just one week. However, they still had no idea about the virus that appeared.

Infectious virus.

It also appeared in the world that Qin Hongfei traveled through. It is a very tricky thing.

It is necessary to judge the infectiousness of the virus, whether it is a dangerous disease, the symptoms that appear, and what cells the virus has infiltrated to cause this. Only then can we analyze it, make an antidote, and a vaccine or drug against viral infection.

The Second Hospital of China and the Second Hospital of Western Medicine have been at odds for many years.

However, after receiving news from Guan County one after another, the Second Hospital seemed to have automatically lifted this barrier.

Bai Yimeng decided to go to Guan County in person.

Qin Hongfei also suspended his plan to return to S Province to accompany her.

Cang Yu also left for Guan County, and he also brought Tang Jinnan and Qi Wu.

In the car...

Qi Wu brushed her hair and was browsing the news on the Internet. "There are all kinds of rumors now. The virus has not been identified and cannot be reported to the public. Hey, what are you two looking at?"

Qin Hongfei's QQ kept ringing.

She has been paying attention to the computer since she got on the car.

"Patient group."

"What is it?" Qi Wu was puzzled and stretched out his hand, "Let me see it."

Qin Hongfei gave him the computer and turned to look at Tang Jinnan, "Does Dean Cang have any ideas?"

Tang Jinnan said yes.

He turned the tablet in his hand and handed it to him. This is the report compiled by the West Hospital this week.

Qin Hongfei glanced through it.

The report is divided into pre-latent period, early stage, symptomatic stage, and aggravated stage.

"Unfortunately, there are too few pathologies to support the theories collected so far." Tang Jinnan said, "Do you have any news?" "

Ahem..." Qin Hongfei returned the tablet to him, "This virus will attack the human urinary system and heart." "

How do you know?" Qi Wu said.

At present, there is no absolute news from below.

Qin Hongpin pointed to the notebook in his hand and said, "I lurked in the patient group of Guan County."

"These are all patients who have fallen ill for no reason in the past few months but could not find the specific cause. The doctors classified them as arrhythmias and urinary tract infections, but none of them worked. I have asked in the group of several hundred people. The onset period of these people is within two to three months. They have never had a similar medical history. Some patients have hereditary diseases such as cardiovascular and cerebrovascular diseases in their families. I screened this part and asked questions. Eighty percent of them are between the ages of 20 and 40, and young people in their twenties account for a large proportion of them."

"Young people have good metabolism, which means that from this point of view, we can rule out the possibility that the disease is caused by family heredity. Even if the hereditary diseases such as cardiovascular and cerebrovascular diseases are inherited from the family, the average age of onset is over 40 years old."

"After screening this part, I asked another part of people who did not have family heredity. The causes were different, but basically 95% of them were diagnosed by doctors as irregular heartbeat and urinary tract infection. The remaining 5% were sudden, and the reports did not show any problems. And 80% of these people have never shown any problems in their past physical examination reports."

Tang Jinnan understood, "You suspect that these patients are related to this infectious disease."

Qin Hongfei said, "That black man, I asked, it's not the first time he entered the country. He has entered the country three times this year. This time he was caught and found out."

"And the last time was at the end of May."

"The earliest onset of these patients was in June."

Qin Hongfei turned the pen in her hand.

Her notes were densely packed.

Tang Jinnan's pretty eyebrows slightly frowned, "If your theory makes sense, then it will be troublesome."

Qi Wu took a breath of cool air and said it was more than troublesome, "If the theory is established, it means that the infectious disease started as early as June, but it was not discovered?"

Qin Hongfei nodded silently: "But the above is just my guess at present."

Tang Jinnan closed the information on his lap and said that we will know when we get there.

It was midnight when they arrived in Dongguan County. Bai Yimeng and Cang Yu went straight to the research institute without resting. Qin Hongfei and Tang Jinnan did not follow them. They asked the teachers to go to Sun Shu first.

Then the three of them went to the isolation area of ​​the hospital in the dark.

Sun Shu was in the isolation area.

When a few people arrived, he was sitting on a stool in a large hospital gown and chatting with the patients across from him. Seeing a few people appear outside the isolation area, he was surprised, "You guys are here, so, Dean Bai and Dean Cang?"

Qi Wu said, "You are here too, Uncle Sun, are you okay?"

Sun Shu got up and walked to the door and said, "Fortunately, I don't feel anything wrong for the time being."

Qin Hongfei turned around and called the medical staff and said something.

Ten minutes later, three people put on protective clothing and entered the isolation area.

Sun Shu immediately wanted to scold them, "It's too dangerous, what are you doing in here."

Qin Hongfei said, "Uncle Sun, we want to check you."

Not only Sun Shu.

Everyone in the quarantine area has to do it.

Sun Shu didn't understand why, but he knew they were not the kind of people who would do it for no reason.

There were a total of six or seven people who came into contact with the black man this time.

An hour later, Qin Hongfei and three others completed a full set of examinations and recorded them.

Among the six or seven people,

four or five had irregular heartbeats during the electrocardiogram, while the others did not.

The patients with irregular heartbeats all had difficulty breathing, frequent urination, and had recently experienced waking up at night.

Two of them had more severe dyspnea!

Qi Wu felt a toothache, "What should we do? The symptoms of the early-stage patients that Junior Sister Qin collected data on are almost the same."

Tang Jinnan asked several people in detail about their contact with the black man.

All had close body contact, and none had seizures. The three had only close body contact and no other contact.

After staying in the quarantine area for more than three hours, Meng Yu came to say that Bai Yimeng and Cang Yu were looking for them, and they hurried to the research institute.

"Teacher..."

"Listen to me!" Bai Yimeng and Qin Hongfei said at the same time.

Everyone was stunned.

Then Bai Yimeng found that the three people were wearing protective clothing, "What did you do?"

Qi Wu said, "Dean Bai, we went to the quarantine area!"

Bai Yimeng frowned.

Other researchers looked over and thought it was a bit ridiculous.

How could they enter the quarantine area so casually?

Cang Yu asked, "What did you find?"

Qin Hongfei picked up the notebook in his hand and said, "Two teachers, the initial judgment is just my personal guess. This virus may have started to spread as early as the end of May. Secondly, the vast majority of people in Dongguan County may have been infected."

As soon as these words came out,

the research institute was shocked.
