Large Quantity Medical Face Mask Sale for Preventing COVID-19
Seeing that the Spring Festival holiday in 2020 has been extended, again and again, no one can be happy because COVID-19 pneumonia has affected everyone’s clothing, food, and shelter. With the increasing number of confirmed diagnoses and the expanding area of infection, the prevention and control of the epidemic have become more important. However, to run the society, production must be resumed, and many enterprises have reached the point of life and death, so resumption of work is necessary.
However, we have not fully figured out the “bottom” of the COVID-19, the inflection point of the epidemic has not yet officially arrived, and difficult times continue. Now returning to work after the holidays, contact between people after work is inevitable, and closed space offices increase the risk of cross-infection. So how do you protect yourself in the face of the COVID-19? Today I have sorted out some precautions in the work area and hope to give you some reference.
Knowledge about COVID-19 pneumonia
Before telling everyone how to protect, it is still necessary to take a few minutes to learn about the COVID-19.
1. What is a COVID-19?
Coronavirus isolated from the lower respiratory tract of patients with unexplained pneumonia in Wuhan is a new type of coronavirus, named COVID-19 by the World Health Organization. Pneumonia caused by it is an acute infectious pneumonia that has the ability to transmit from person to person. The first patient was found in Wuhan City, Hubei Province on December 12, 2019, and the epidemic has now spread to the whole country.
2. Who is susceptible to the COVID-19?
The crowd is generally susceptible. COVID-19-infected pneumonia can occur in people with low immune function and normal immune function, and it is related to the amount of virus exposure. For people with poor immune function, such as the elderly, pregnant women, people with liver and kidney dysfunction, and people with chronic diseases, the condition is more severe after infection.
3. What are the transmission routes of the COVID-19?
The main route of transmission of the COVID-19 is through respiratory droplets, which can also be transmitted through contact (droplets or other virus-bearing body fluids are deposited on the surface of the article, and the hands are in contact with the contamination, and then contact the oral, nasal, and eye mucous membranes, causing infection) It has the characteristics of human-to-human transmission, and there is a certain range of community transmission. As for the aerosol and fecal-oral transmission channels, it needs to be further clarified. So, the more densely populated the place, the more likely it is to cause the virus to spread.
4. What are the symptoms of pneumonia in patients with COVID-19 infection?
The initial symptoms of the patients are mostly fever, dry cough, and fatigue (asymptomatic patients have appeared). A few patients have symptoms such as nasal congestion, runny nose, and diarrhea. Severe patients often experience dyspnea after one week. In severe cases, it can quickly progress to acute respiratory distress syndrome or septic shock, and eventually die. There are also some patients with low fever, mild fatigue, etc., without pneumonia, and usually recover after one week.
Based on the current epidemiological survey, the incubation period is generally 3-7 days, and the longest does not exceed 14 days. At present, there are no effective antiviral drugs. Isolation therapy and symptomatic supportive therapy are mainly used. Therefore, the pathogenic ability of the COVID-19 is still very strong. Please pay attention to it and protect yourself.
5. Why focus on close contacts and isolation?
Close contacts refer to those who have lived or worked with suspected cases, confirmed cases, mild cases, and asymptomatic infection (positive test), but did not take effective protection. The contact situation includes contact with colleagues in the office, students in the same classroom and dormitory, the same machine, the same taxi, the same elevator, etc., as well as the escort, diagnosis and treatment of patients infected with the virus. Anyone who has been exposed to the case, please don’t hide it. Because you may already be infected, and you may become a potentially high-risk source of infection.
Therefore, close contacts need to take isolated medical observation, and the observation period is 14 days after the last unprotected contact with the case or infected person. Do not go out during medical observation. Once any symptoms, especially fever, respiratory symptoms such as cough, shortness of breath, etc., please do not panic, report to the local health department immediately, and send them to a designated medical institution for treatment.
6. Relevant knowledge and use of masks?
As the most important point in the protection process, everyone focuses on when to wear the mask, how to choose it, how to use it, etc. Let us talk about it separately here.

Go to public places (such as shopping malls, supermarkets, hospitals, pharmacies, gyms, etc.); take public transportation; external service jobs (such as office halls, front desks and other staff); hold collective meetings; closed offices such as more offices.
(2) How to choose a face mask?
Generally, disposable medical face masks are used. Cotton masks and sponge masks are not recommended. In crowded and confined places (such as shopping malls, buses, subways, and airplanes), wear disposable medical surgical masks and continuously replace them for 2-4 hours, and immediately replace them after contamination or humidity. For people with higher risk exposure, For example, public health physicians who work in the emergency department, etc., who carry out epidemiological investigations on close contacts, can use standard N95 medical protective masks and replace them for 4 hours continuously, and immediately replace them after pollution or humidity.
(3) How to use a face mask correctly?
Wash your hands before wearing a mask; the side of the nose clip is facing up and the dark side is facing outwards; unfold the stack and use your hand to fix the mask to your face so that it covers the mouth, nose, and jaw; pull the ear strap behind the ear and adjust The elasticity of the earband, without causing discomfort to the head and face, the strap should be pulled to the tightest; press the tip of your two fingers along the metal piece of the nose bridge from the center to the sides, and slowly press inward until it is close to the nose bridge; Adjust the mask appropriately so that the periphery of the mask fits the face fully.
