COVID-19 is terrible, and the flu virus is not good! Sinashu gives you peace of mind!

  The mutation of COVID-19 and the acceleration of the epidemic have made once peaceful life turbulent again. The rampage of COVID-19 is undoubtedly a global disaster, but what you may not know is that our common influenza virus has caused global disasters many times.


  Spanish influenza: In 1918-1919, the virus type H1N1 caused 20 to 40 million deaths.

  Asian influenza: from 1957 to 1958, the virus type H2N2 caused 1 to 4 million deaths worldwide.

  Influenza in Hong Kong: from 1968 to 1969, the virus type H3N2 spread to 55 countries and regions around the world, causing 2 million deaths.

  Russian influenza: 1977-1978, the virus type was H1N1, and the number of deaths was not recorded.


  Even though humans have been fighting against influenza viruses for hundreds of years, influenza vaccines are becoming more and more mature. However, in 2019,The United States has another outbreak of pandemic influenza,At least 34 million people were infected。


  On September 21, 2019, the Southern Metropolis Daily published a set of figures based on the research literature of the American authoritative magazine Lancet Public Health:The study found that 88000 people died of influenza every year in China.


  Influenza is divided into three subtypes: A, B and C.

  Influenza A virus has a wide range of hosts and is prone to mutation, which has caused world pandemics for many times;

  Influenza B virus has few mutations and usually only causes local outbreaks;

  Influenza C virus is stable, mostly sporadic, and mainly affects infants and people with low immunity.

  Influenza A virus can be divided into several subtypes according to the antigenicity of HA and NA. HA can be divided into H1~H18 subtypes, and NA can be divided into N1~N11 subtypes,Human influenza is mainly related to H1, H2, H3 and N1, N2 subtypes (H1N1, H2N2, H3N2 mainly infect humans).


  Avian influenza also belongs to influenza A virus. At present, H5N1, H7N7 and H9N2 avian influenza viruses have been found to infect humans.


  Influenza virus is highly infectious, spreads rapidly, and is generally susceptible to people. Antibodies appeared one week after infection or vaccination, reached a peak in 2-3 weeks, began to decline after 1-2 months, and dropped to a lower level about one year. Therefore, influenza vaccine needs to be re vaccinated every year.


  However, because influenza virus belongs to RNA virus, its gene is divided into 8 segments, which can be replicated separately, so it is relatively easy to mutate, resulting in different subtypes of influenza virus circulating every year. That is to say, although the person who received the vaccine against influenza virus subtype X last year had protective antibodies against influenza virus subtype X in his body, when influenza virus subtype Y was prevalent this year, his body was still unprotected and exposed, just like the person who did not receive the vaccine.


  Now we all know that to prevent COVID-19 or influenza, it is recommended to wear a mask when going out. How do masks protect against viruses? Let's first understand the size of the virus.


  The shape and size of viruses vary. Most viruses have a diameter of 10-300 nanometers, or 0.01-0.3 microns. The particle size of PM2.5, as we often say, is 2.5 microns, which differs by an order of magnitude.


  If the virus is so small, will the anti haze mask be unable to resist the flu virus? Not really. Here we would like to mention a physical concept called aerosol. Aerosol is a suspension system of liquid or solid particles in the air. It has colloidal properties and great surface energy, with obvious adsorption and sedimentation.


  Although the particle size of the virus is very small, it cannot exist independently. It attaches to the particulate matter of aerosols in the air, such as droplets when sneezing. In this way, the problem of filtering viruses becomes the problem of filtering aerosol particles. As the core filter layer, the meltblown cloth in the mask has a good filtering effect on virus containing droplets or aerosols. It can be seen that aerosols in the air play an assisting role in resisting viruses.


  Not only that, some aerosols with specific properties can even directly inactivate viruses!


  Nanjing Kuancheng Technology Co., Ltd——Sinashu The salt sol therapeutic apparatus has carried out the 'inactivation test of influenza A virus H1N1',The result shows that: at 20m ³ In the confined space, when the saline sol therapeutic apparatus is turned on for 60 minutes, the inactivation rate of influenza A virus (H1N1) in the aerosol chamber is 99.9%.


  As early as 2017, the research results published by the Canadian 'University of Alberta' research team in the magazine NATURE revealed the role of salt particles on viruses: when salt particles in the crystalline state come into contact with virus containing particles, they can pierce the virus shell, making it rapidly inactivated.


  The constant release of the Sinasul salt sol therapeutic apparatus into the air is 1-5 microns, dry Salt aerosol.


  For the external air environment, it has the function of disinfection and sterilization, sensing and controlling, and efficient purification.


  In addition to the inactivation of influenza A virus, the therapeutic apparatus of Sinashu salt sol also killed 99.9% of Staphylococcus albus in the air and more than 96% of other natural bacteria in the air. At present, it has been used in many general hospitals and rehabilitation hospitals in situations requiring great attention to infection control, such as tracheotomy, lung transplantation rehabilitation and intensive care unit, and all of them have shown positive effects.


  For the internal environment of human respiratory tract, it has the effects of sterilization, anti-inflammatory, edema elimination, sputum excretion and immune regulation.


  For patients suffering from rhinitis, asthma, chronic obstructive pulmonary disease, chronic bronchitis and other diseases, long-term use of Sinasul salt sol therapeutic instrument can effectively improve the pulmonary function of patients, reduce drug dependence and reduce the number of acute attacks. Many experts in respiratory department, pediatrics and rehabilitation department recommend using this non drug therapy to rehabilitate respiratory diseases. External protection+internal protection, fully resist the virus attack. In the New Year, Sinashu gives you and your family a reassuring protection!
