What is the reason for the sudden increase in the number of new crown pneumonia cases in Hubei? How to view the number of new cases in Hubei exceeding 10,000

After the news of 14,840 new cases of COVID-19 in Hubei came out, many people were shocked. Why did the number of new cases exceed 10,000 in one day? Is it because the number of infections is increasing and the epidemic is out of control, or is it that the epidemic has been brought under control now? In fact, this sudden increase is due to the change in the diagnostic criteria. Don't panic. Next, let's take a look at the detailed introduction provided by this website.

Why is there a sudden increase in the number of COVID-19 cases in Hubei?

On February 12, Hubei Province added 14,840 new cases of COVID-19 (including 13,332 clinically diagnosed cases). Why did the number of confirmed cases in Hubei increase dramatically overnight? The reporter learned from the National Health Commission on the 13th that with the deepening of the understanding of the new coronavirus pneumonia and the accumulation of diagnosis and treatment experience, in view of the characteristics of the epidemic in Hubei Province, the General Office of the National Health Commission and the Office of the State Administration of Traditional Chinese Medicine issued the "Diagnosis and Treatment Program for Pneumonia Infected by the New Coronavirus (Trial Fifth Edition)" to add "clinical diagnosis" to the case diagnosis classification in Hubei Province, so that patients can be diagnosed and treated early, and the success rate of treatment can be further improved. According to the plan, Hubei Province has recently conducted a screening of suspected cases in the past and revised the diagnosis results, and diagnosed new patients according to the new diagnosis classification.

It's a good thing! In the past, the diagnosis of COVID-19 mainly relied on nucleic acid testing, but COVID-19 is a lower respiratory tract infection, and the pharyngeal swabs used for testing come from the upper respiratory tract. Patients do not always have sputum, so false negatives are often found in the specimens taken, resulting in many suspected cases having symptoms but being unable to be diagnosed. Newly added to the fifth edition of the guidelines is a lung CT scan. If the patient has imaging changes, namely lung inflammation and ground-glass shadows, it proves that he has been infected with the virus. After being included in the clinical diagnosis, the number of confirmed cases in Hubei will continue to increase significantly, but the turning point is approaching. This proves that the policy of admitting all patients who should be admitted has been implemented after Chen Yixin took office. At the same time, the surge in patients has also put higher demands on the number of medical staff. Jiangsu has sent several medical teams, all of which are elite from top hospitals. I believe that the annihilation campaign in Hubei Province will be successful.

What is a clinical diagnosis case?

Tong Zhaohui: When we diagnose pneumonia, we can only get 20 to 30 percent of the etiology, and the remaining 70 to 80 percent depends on clinical diagnosis. From the perspective of clinical thinking and the clinical pathway of clinicians, increasing the diagnosis of clinical cases will help clinicians make more judgments on the disease.

Some time ago, we mainly relied on nucleic acid to confirm cases. In fact, according to our clinical diagnosis standards, there are a large number of suspected cases.

In clinical work, we make comprehensive diagnoses from the following aspects: First, if the patient is in Hubei or Wuhan, then there must be an epidemiological history; second, fever, respiratory cough, and breathlessness are clinical symptoms; third, clinical signs and physical examinations; fourth, CT images. For example, the common pneumococcal pneumonia, the actual positive rate and culture rate are only 20 to 30%, and most of the clinical cases are diagnosed by clinical doctors.

It is a good thing that we no longer rely on test kits, but directly identify patients based on clinical symptoms - lung films, body temperature, cough, etc. - and quickly treat those who need treatment, so as to avoid the displacement of infected people.

It is equivalent to a listed company making a one-time provision, taking a bath, and starting over.

But the medical staff in Wuhan will be under increasing pressure. The medical staff in Wuhan and those from all over the country who have provided support in the early stages are far from enough, and the number should continue to increase. I saw the news today that the People's Liberation Army will send another 2,600 medical staff to Hubei, and for the first time dispatched the Y-20, which has carried 1,400 military medical staff to Wuhan today. I won't say more. In one word, I give a thumbs up to the people's soldiers!
