Popular science! Yuan Lei takes you to know the difference between cold, flu and new coronavirus pneumonia.




A cold is a disease that is mainly manifested by nasopharyngeal and upper respiratory symptoms caused by factors such as cold and fatigue. The most obvious ones are nasal congestion, runny nose, and sneezing. There is no obvious fever, physical strength and appetite are not significantly affected, and generally There are no obvious symptoms such as headache, joint pain, and general discomfort.People with colds generally have severe upper respiratory symptoms, but their general performance is very light. Even this person still has a certain amount of energy and physical strength to continue working. Generally speaking, there is no danger.


Cold patients often have sneezing, runny nose and other upper respiratory symptoms, but fatigue, fever, cough and other symptoms are not obvious; influenza is a respiratory tract infection caused by influenza virus, and it is also the season of high incidence of influenza. The symptoms of influenza patients are more serious and acute, In the first 1-2 days of the onset, a series of symptoms such as high fever, headache, muscle soreness, joint pain, fatigue, loss of appetite and so on;However, most patients with pneumonia infected by novel coronavirus have a relatively slow onset, especially in the first three days of the onset, they will have a little low fever, cough, chills and other symptoms, which are often not too serious. As the disease progresses, the symptoms will become more and more serious on days 5-7.Because the early symptoms of this disease are relatively mild, there are still some infected patients attending parties, traveling, shopping malls, etc. The patients with these symptoms need the most attention at present.





Influenza is a respiratory disease caused by influenza virus infection. It often causes not only upper respiratory tract problems, but also lower respiratory tract infections, namely pneumonia.This is a typical respiratory infectious disease, especially in winter and spring. It is almost epidemic every year. There are influenza A and influenza B. Now it is the season of high incidence of influenza.


Influenza patients often have acute onset and severe symptoms, especially systemic symptoms, fever, body temperature may rise to 39 degrees or 40 degrees within one or two days of onset, headache, muscle fatigue, loss of appetite and other symptoms are obvious.After a person gets the flu, he often feels that his condition is serious, and he will go to the hospital in a hurry. Among the flu patients, there are some relatively mild people, such as the elderly, children, obese people, pregnant women or people with underlying diseases. Influenza can lead to very serious severe pneumonia and even death. Every year, many people die of influenza, which is an epidemic disease every year.



novel coronavirus pneumonia


Most patients with pneumonia from the novel coronavirus infection,The onset of the disease is relatively slow, especially in the first three days of the onset, there will be a little low fever, cough, chills and other symptoms, often not too serious, as the disease progresses, the symptoms will become more serious on the 5th-7th day.


Early detection is severe patients, especially some elderly people, and even severe pneumonia can lead to death. From the analysis of the disease itself and more patients, it is found that a small number of people do not even get sick after infection. Only the virus is detected in the respiratory tract. There are also patients with mild symptoms. Some people may be mild after infection. With only a little fever, cough, chills and physical discomfort, the patient recovered after about 7 days.


Patients with ordinary new coronavirus pneumonia will have symptoms such as fever, cough, and gradually aggravating fatigue. The early symptoms are relatively mild, but by about a week, the condition will gradually worsen and develop into pneumonia or even severe pneumonia.Therefore, typical cases of new coronavirus infection will have a gradual aggravation process, especially in the second week, the disease that often manifests is the most serious.


And some severe patients will have rapid breathing, respiratory failure and even multiple organ damage symptoms. Further, some people will need ventilator support, concentration shock, and even multiple organ failure need some life support system support. These are critically ill cases and may lead to death.


At present, pneumonia caused by novel coronavirus infection belongs to Class B infectious diseases, but is managed according to Class A infectious diseases. In the prevention and control of infectious diseases, it is necessary to control the source of infection, especially for some people who are asymptomatic carriers of novel coronavirus. It is very important to observe at home for 14 days. This kind of self-medical management is an important means to cut off the transmission route. Individuals returning from the field must report to the unit. In particular, people who come back from Wuhan and other areas with more cases should carry out self-observation, take their temperature one morning and one night, and report to the disease control department.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

Yuan Lei's Little Knowledge | Application Effects of Different Mineral Powder Materials in Coatings


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.

Yuan Lei's Little Knowledge | Characteristics of Mineral Materials


Mineral materials refer to the material products obtained by processing and transforming natural minerals (mainly non-metallic minerals) or rocks as the main raw materials, or minerals or rocks that can be directly used as materials and aim to utilize their main physical and chemical properties. This meaning mainly includes the following four aspects: first, natural minerals and rocks that can be directly utilized or processed to be utilized; Secondly, finished or semi-finished materials made mainly from natural non-metallic minerals and rocks through physical and chemical reactions; Thirdly, artificially synthesized minerals or rocks; Fourthly, the direct utilization targets of these materials are mainly their own physical or chemical properties, not limited to individual chemical elements.
