I can see the status bar

Chapter 963 - 19 D-day

Yunhe made the second proactive report. At present, a total of 59 cases of viral pneumonia of unknown cause have been reported in the city.Among them, 11 cases were severe.No evidence of human-to-human transmission has been found, and no infections among medical staff have been reported.

After chatting with Liu Tangchun yesterday, Sun Lien's eyes on this data suddenly became... strange.On the one hand, he really does not want to see a sharp increase in the number of confirmed cases.But at the same time, he hopes that the local area can quickly clarify the specific infection situation, so that the infectious disease can be brought under control as soon as possible.

From a subjective point of view, Sun Lien feels that the performance of the virus this time does not seem to be as terrible as SARS back then.Back then, SARS was a terrible virus that could infect an entire floor or even an entire apartment building in one breath.

But from an objective point of view, Sun Lien does not think this judgment is correct.There are currently six types of human coronaviruses. Although the first four are not small in transmission, most of them can only cause common cold symptoms.The other two coronaviruses that can cause SARS and MERS have strong transmissibility and high lethality respectively.

MERS致死率约为30%，而SARS的致死率约为10%。根据现有的数据来看，MERS冠状病毒的基本传染数R0小于1，而SARS冠状病毒的基本传染数R0则在2~5之间。

基本传染数R0是一项公共卫生研究和病毒领域的重要参数。它能够直观的体现出各个病毒的传播能力和持续传播效应。当R0大于1时，意味着病原体将在人群没有针对性保护的情况下增加感染人数。而当R0小于1时，病原体的传播将呈自限性并且逐渐在人群中消失。

R0=2, which means that without protection, an infected person can infect at least two healthy people on average.

The low R0 of the MERS virus is not because of the high mortality rate that causes a large number of carriers to die before infecting others.In fact, even the Ebola virus, which has a mortality rate as high as 70%, has a basic infection number R0 of around 2.3. The reason why the R0 of MERS is less than 1 is about 0.6.This difference is mainly due to the fact that this virion exhibited a marked decrease in intergenerational transmissibility.

As a coronavirus, so far, the MERS virus does not have the ability to pass from person to person for the fifth generation.The transmission ability of this virus will decline significantly with the intergenerational transmission.Therefore, it can be considered that the MERS virus belongs to a virus with "limited human-to-human transmission".It does not pose a serious threat to the lives of the general public.

The SARS virus is a virus that can "sustained human-to-human transmission".It has not shown a decline in the ability of intergenerational transmission, and will continue to spread among the population.

The problem now is that everyone knows nothing about this virus that is quietly spreading in the Yunhe area.Because of the lack of sufficient data, it is impossible to judge whether it has the ability of human-to-human transmission, nor can it be judged whether it will have the same decline in intergenerational transmission ability as the MERS virus.

And Sun Lien's worry comes from this-compared with the first notification, the third notification added 32 patients.In the four days since December 12, the number of confirmed patients has only slightly more than doubled.This means that either the transmission of this newly discovered coronavirus is extremely weak, and its R31 is much less than 0, or it means that there are still a large number of patients who have not been discovered and diagnosed.

When something has the potential to go bad, most of the time it does.

After thinking about this matter, Sun Lien's mood became very bad.

I hope that the front-line staff can complete the whole genome sequencing of the virus as soon as possible, so that at least researchers and doctors who have not obtained the pathogen can have a general understanding of the virus.

In the afternoon, Han Wenping suddenly appeared in Sun Lien's office.It can be seen that Director Han has been under a lot of pressure these days - there are a lot of white hairs on his head.

"Director Sun, I have something to ask for your help." Director Han sat on the stool in front of Sun Lien with a serious expression, "I remember that you are quite familiar with Yuhua Group, right?"

"Shen and I always have some...friendship." The last time Sun Lien saw Shen Qingmei was during Chinese New Year last year, but since Han Wenping asked this question, he could only answer the question first, "you find Yuhua What's the matter?"

"We need to purchase a batch of masks and protective clothing. The quantity is large and the need is urgent." Director Han sighed and said, "The current situation is not optimistic. Almost all of our previous suppliers have gone on vacation. There is a It’s not a holiday yet, but there’s simply not enough stock in the warehouse.”

"But Yuhua...they only have the third pharmaceutical factory under their umbrella?" Sun Lien asked, "The pharmaceutical factory doesn't produce masks either?"

"Since getting in touch with Takeda, Yuhua has been developing in the direction of medical equipment. They now have two factories, which are responsible for the production of sterile dressings and protective clothing." Han Wenping sighed again, "I also have It is true that there is no manufacturer that can supply, otherwise this kind of thing must go through the bidding first.”

"Then... let me ask?" Sun Li'en didn't know how he could help with this kind of matter.Although Shen Qingmei is very affectionate, it is obvious that she is a very qualified businessman and an excellent entrepreneur.

Sun Li'en really didn't think he could have any "face" in front of Shen Qingmei.

"Ask..." Director Han sighed again, "Now the king of Hades is easy to see, and the little ghost is hard to deal with. I have communicated with Yuhua's sales department many times, and people have pushed back .”

"Then I'll ask now." Now that it's said, let's do it quickly.Sun Li'en directly dialed Shen Qingmei's phone number, and then accepted the purchase request from Han Wenping at the same time.

The call hadn't been connected yet, but after seeing the purchase request, Sun Li'en himself was startled.

This purchase volume is definitely not small. There are 20 strap-on medical surgical masks, 95 ear-hanging masks, and 95 N[-] or KN[-] medical masks.At the same time, the Fourth Hospital will also purchase [-] sets of protective clothing, [-] sets of positive pressure headgear and related supporting equipment.

The purchase order totaled more than 160 million.

When Sun Lien saw the purchase price, Sun Li'en's first reaction was confusion - the order of 160 million, no matter how big the company is, the sales department would not care about it.Signing a supply agreement with a hospital is a major event for any manufacturer of medical devices, which often means a steady stream of purchase orders in the future.

When Sun Lien was puzzled, the call was connected.After listening to Sun Li'en's report of the purchase request, Shen Qingmei was silent for a while before saying, "Xiao Sun, it's not that my sister doesn't give you this face. But this list...we can't do it according to your request."
