China News Service, Beijing, August 4th (Journey) Currently, the world is focusing on the WHO's second phase of the new crown virus traceability plan, and more and more scientists are calling for a thorough investigation of e-cigarette pneumonia in the United States.

For a long time, the outside world has questioned the relationship between e-cigarette pneumonia and new crown pneumonia in the United States, but the United States has always avoided talking about it.

Recently, a new study pointed out that e-cigarette pneumonia and the new crown pneumonia in the United States have a relationship between “cutting and chaos”.

　　In July 2019, the Fort Detrick Biological Laboratory in the United States was shut down. At the same time, an e-cigarette pneumonia swept across many states in the United States. The patient's symptoms were almost the same as the symptoms of new coronary pneumonia, and the cause of the disease was unknown.

Combing the symptoms and timing of e-cigarette pneumonia patients in the United States, it is not difficult to find many doubts.

　　Doubt 1: The CT images and clinical manifestations of e-cigarette patients are not specific.

The so-called electronic pneumonia patients in the United States is actually a general term for patients with pneumonia who smoke e-cigarettes without other reasonable diagnostic evidence.

These patients smoked e-cigarettes within 90 days before the onset of the disease. It is especially worth noting that the CT imaging characteristics and clinical manifestations of some patients are very similar to those of viral pneumonia patients.

Axial CT scan of the middle and lower lungs showed ground-glass opacity with subpleural retention.

　　Doubt two, Chinese researchers selected 250 images of 142 patients with e-cigarette pneumonia from 60 research papers, and invited 3 radiology experts to conduct a review of all the above-mentioned images, relevant patient clinical information, and the original text of the literature. After careful and comprehensive research and review, new discoveries were made.

The axial CT plain scan image after 6 days showed that the ground glass shadow became consolidation and slight structural distortion.

　　Sixteen patients with e-cigarette pneumonia reported in the literature were judged by experts as “viral infection”, that is, they may be “suspected patients” with new coronary pneumonia. Among them, 5 patients with relatively complete clinical symptoms and treatment conditions were judged It is "moderately suspicious".

Therefore, there are cases of viral infection in e-cigarette pneumonia reported in the United States in 2019, and the possibility of new coronary pneumonia in e-cigarette pneumonia in the United States is not ruled out.

　　Suspicious point three, these 16 patients are all from the United States, of which the time of onset of 4 patients is unknown, and the time of onset of the remaining 12 patients is before 2020.

In response to reports and reports of early COVID-19 cases in the United States that may be earlier than the known time, the United States has never responded.

　　In fact, as scientists from many countries continue to study the traceability of the new coronavirus, many studies have shown that the emergence of the new coronavirus in many places around the world is earlier than the previously known time.

From a global perspective, the epidemic of new coronary pneumonia is increasingly showing signs of multiple sources and multiple outbreaks.

This also proves once again that it is necessary to trace the source of the new crown epidemic in multiple locations.

　　The above three doubts have caused the outside world to once again question the relationship between e-cigarette pneumonia and new crown pneumonia in the United States. Therefore, experts also actively call for new crown traceability to investigate the truth of e-cigarette pneumonia in the United States as soon as possible.

　　With regard to the issue of virus traceability, the United States, while requesting investigations into other countries, refuses to disclose relevant data of its own country. This approach is difficult to convince the international community.

　　Now that the suspicion of e-cigarette pneumonia is reappearing, in the face of doubt, the United States should face the problem squarely, take it seriously, respond to international appeals and actively cooperate, and buy precious time to promote the traceability of the new crown instead of politicizing the epidemic, stigmatizing the virus, and instrumentalizing the traceability. Provide scientific support for the global fight against the epidemic.
