Scientists from the University of Hong Kong found out the temperatures at which the new coronavirus COVID-19 Naimore and least active. According to the study, quoted by TASS, the virus is kept highly stable at a temperature of about 4 degrees Celsius. In the absence of its disinfection activity begins to decrease only after 14 days.
this COVID-19 is very sensitive to high temperatures at +70° C, and he dies within five minutes. At +56° coronavirus has been active less than half an hour at +37 degrees C, no more than two days at a temperature of 22 degrees – for about a week. Scientists have also found out how long the virus can live on various surfaces.
So, on the outside of medical masks it is hardy at least a week at room temperature and a relative humidity of 65%. On paper coronavirus lasts less than three hours on wood and fabrics – no more than two days on glass – less than four days on stainless steel and plastic – no longer than a week.
the CPS was made on Monday with an explanation regarding reusable cloth masks, sale ads which appear on the Internet. The Ministry stressed that such masks are not medical products, and to re-use them only after careful processing. As in the case of disposable medical masks, cloth masks should be changed every two to three hours of constant use.
“At home mask should be washed with soap or detergent, then treating with a steam generator or iron with the steam function. After processing the mask should not stay wet, so in the end it must be ironed with a hot iron without the steam function,” he described the procedure on the website of Rospotrebnadzor.
the Ministry recalled that the mask is intended primarily for those who are already sick, and is only effective in combination with other prevention methods (avoiding contact, frequent hand washing, disinfection of objects). Also the mask should be worn by people providing health help the sick and care for them.
Healthy people can use the mask when visiting public places, on public transport, but the effectiveness of the mask in such situations has not been proven. Disposable medical masks non-woven material can not be reused and any treatment. At home this mask before disposal, you need to put in a separate packet, seal it and then throw it in the trash.
as for temperatures, the survival of coronavirus, the scientists also examined the influence of various weather conditions. Experts from the Massachusetts Institute of technology (MIT) found that 90% of cases COVID-19 occurred at temperatures from 3 to 17°C and an absolute humidity of 4 to 9 g/m3. If their assumption is true, then warm and humid weather in the coming months may improve the situation in many countries of the Northern hemisphere and in the southern hemisphere it could get worse. However, this does not mean that the coronavirus does not spread in countries with warm and humid climate.
this, in particular, draws the attention of the scientific Director of the hydrometeorological center of Russia Roman Vilfand. “In the same Thailand, where the temperature is about 30 degrees, there is a coronavirus, and hard action against him. In the middle East, Turkey, Israel, Syria, the temperature is about 25 degrees, and nothing, it spreads actively,” – said the expert.
At the same time, according to him, it is impossible to exclude and a complete lack of the influence of climate on the spread of coronavirus infection. Vilfand admitted that indirectly, this is somehow affected by solar activity, but need a strong evidence base.
researchers from Lanzhou University have previously found a relationship between weather conditions and mortality from COVID-19. In the Chinese city of Wuhan the number of victims increased with a larger temperature difference day and night and under low humidSTI.
