Chapter 1002 D+1 day (2) (addition 03 for the leader "changing the name is too expensive")

This chapter is Chapter 3, which is updated for the leader "It's too expensive to change the name". After this chapter, there are four more chapters waiting to be updated.

Sun Lien's so-called way refers to the Yuhua Group far away in Ningyuan.At that time, Shen Qingmei had stored up the production capacity for more than a month but refused to ship out. Now that I think about it, I am probably preparing for the situation today.

However, when Yunhe's health committee staff heard the words "Ningyuan Yuhua", their expressions suddenly became disappointed.According to them, Ningyuan Yuhua had contacted them a long time ago, and expressed very positively that they were willing to do their best to ensure the supply of Yunhe.

But the ability of a company is limited. As for how to find other resources... It is impossible to find enough supply in the country relying on Yunhe's own strength.This requires the joint efforts of the whole country, and it will take a long period of time to achieve it.

However, the short face-to-face communication still gave Sun Lien some opportunities to understand the situation.

"The medical team members from the three armies have arrived at Yunhe, and there will be medical teams from all over the country coming to Yunhe starting today." The staff of the Health and Medical Commission have a much more timely understanding of the current situation than Sun Lien and the others, "Yesterday's new A total of 77 cases have been reported in the city."

"77 cases? My ward admitted three new ones yesterday." Sun Lien was a little unbelievable about this data, "All 48 beds in my ward are full!"

"Without PCR testing, there is no way to treat them as confirmed cases." The staff of the Health and Medical Commission scratched their heads, looking worried, "The city's PCR testing capabilities are now being fully strengthened, and equipment from other places has been supported. The laboratory and staff are on the way, but it will take time to get here. The new coronavirus is currently listed as a Class B legal infectious disease, and Class A management. Its diagnosis needs to comply with the law... We can't help it! "

The Law on the Prevention and Control of Infectious Diseases is a law, and its authority cannot be shaken.Even if the patient's symptoms completely match all the symptoms of viral pneumonia, even a confirmed patient has appeared among close contacts.However, until the positive PCR results appear, this patient still cannot be regarded as a pneumonia patient infected by the new coronavirus.

"This won't work." Sun Li'en was a little anxious, "This disease is very contagious, and we don't know when the infected person will start to excrete the virus and spread it - there are patients who don't have a fever after infection, so we can't copy it mechanically." The experience with SARS back then!"

The reason why SARS was quickly brought under control was that, on the one hand, the whole country attached great importance to it and actively responded to it, and on the other hand, it was because of the special transmission mechanism of SARS—carriers would not excrete the virus before they had a fever, so they were not contagious .As long as all febrile patients are tested for relevant pathogens, and the febrile patients are isolated, the purpose of effective control of transmission can be achieved.

However, the family of six sent to the Comprehensive Diagnostic Center proved that the new coronavirus is not such a "mild" thing.Zhou Yuze, the youngest, has no symptoms of new coronavirus infection such as fever, diarrhea and cough.However, genetic fragments of the new coronavirus could still be detected in his upper respiratory samples.

Although Ning Yuan has not been able to confirm that the virus gene detected in the upper respiratory tract of the asymptomatic Zhou Yuze is a non-infectious live virus.But the risk is real.

Sun Li’en’s laboratory is not new to the PCR detection kit—at present, there are few manufacturers of PCR kits in China with both accuracy and mass production capacity, and Yuhua Biotech is one of the best.

And even the kit produced by Yuhua Biotechnology, when testing Zhou Yuze and his grandmother Zeng Xia, it also showed negative results for multiple nucleic acid tests.Zeng Xia's symptoms worsened later, and she tested positive for nucleic acid.

When the accuracy of PCR test kits is not yet reliable, setting the diagnostic standards for infectious diseases so high is not conducive to rapid control of transmission.

"It won't work like this." Sun Lien turned around in a hurry, he suddenly stopped and asked, "Can you report the diagnostic criteria to your superiors?"

"Of course." The staff member of the Health and Medical Commission nodded, then took out his notebook and said, "Director Sun, tell me."

"I suggest that the diagnosis process be adjusted. At least one more diagnostic standard than 'suspected cases' should be added." Sun Lien sorted out his thoughts and said, "Once a close contact of a confirmed patient develops symptoms, it should be carried out as this higher standard. Isolation and treatment. Patients cannot be allowed to stay at home for observation, and the conditions for home observation are insufficient, which will only allow them to spread to more people."

"Diagnosis based solely on epidemiological investigations and symptoms? This consumes a lot of human resources." The staff of the Health and Medical Commission frowned and asked, "Will this be a bit one-sided?"

"Based on our current experience, the onset of a large number of patients is hidden." Sun Lien said seriously, "It is already very slow to ask patients to show symptoms before diagnosing."

"Then..." the staff of the Health Commission stopped writing, "Are there any other indications and suggestions? Changes in blood patterns or fever?"

"The fever is not obvious." Sun Li'en frowned, "I am in the North Fifth District of Yunhe City Infectious Diseases Hospital, and there is a severe patient who was diagnosed with pneumonia caused by a new type of coronavirus. The person was on invasive ventilation, and his blood oxygen saturation was still high. Not coming—but he doesn't have a fever, 36 degrees eight."

"These patients always have common characteristics, right?" The staff of the Health and Medical Commission was a little puzzled, "Mr. Sun, your suggestion is very good, but we have to consider the difficulty of implementation."

Sun Li'en frowned and thought for a long time, and then suddenly he had a flash of inspiration.

"Imaging data can be used." Sun Lien said quickly, "Using CT to scan the chest, as long as ground-glass lesions are found, combined with epidemiological history or contact history with confirmed patients."

"Is it possible to treat other patients with viral pneumonia as patients with new coronavirus infection?" The staff member of the Health and Medical Commission was still hesitant, "If because of this, patients with other viral pneumonia will be infected instead. If you get a new type of coronavirus, you will suffer."

"So, we still need more treatment capacity." Sun Lien said, "I suggest that the relevant departments requisition existing buildings including hotels and schools as soon as possible, and then have imaging features and contact history for these, but no PCR or PCR-negative patients are quarantined for observation. This can block the risk of family transmission on the one hand, and prevent other patients who are not infected with the new coronavirus from being infected in the hospital on the other hand."

"Oh, by the way, there is one more point." Sun Lien reminded, "If CT examination is performed, it must be noted that after each CT examination, the equipment and room must be thoroughly disinfected, and the patient passages should also be differentiated to prevent the inspection process. infected."
