It was found that the new coronavirus was infectious or changed with room humidity

According to the Canadian “digital magazine” website on August 30, the new study takes into account the influence of room humidity on the spread of the new coronavirus. The source of transmission is not only related to indoor people and their interaction, but also some virus particles may enter the indoor environment from different emission sources with the help of environmental factors. < / P > < p > based on environmental factors and virus transmission, this new study analyzes the influence of relative humidity on aerosol transmission. Relative humidity is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. < / P > < p > researchers have found evidence of the role of relative humidity in the airborne transmission of viruses in indoor environments. Humidity is an important factor because it affects evaporation movement and particle formation. It was found that the possibility of air transmission of coronavirus in dry indoor buildings was greater than that in wet areas. < / P > < p > it is found that relative humidity between 40% and 60% is the most ideal for indoor human health. Researchers believe that the minimum relative humidity standard for indoor environment should be established. In addition, there is evidence that the surface stability of SARS coronavirus 2 is higher than that of SARS virus in 2003. < / P > < p > the related research report was published in the Journal of aerosol and air quality research, entitled “overview of the effect of relative humidity on the air transmission of severe acute respiratory syndrome coronavirus 2 in indoor environment”.
