Researchers on the corona virus continue to search around the world. Meanwhile, Australia’s National Science Agency CSIRO has made a new claim regarding the corona virus. CSIRO says that the virus remains infected for a longer time in a controlled environment. This study has been published in the journal Virology.
CSIRO researchers found that at 20 ° C (68 ° F) the SARS-COV-2 virus remains contagious for 28 days on smooth surfaces such as mobile phone screens, notes, and glass. In comparison, influenza A virus remains alive on the surface for 17 days.
Shane Riedel, the lead researcher of the study, said, “This study actually enhances the importance of washing hands, sanitizing and keeping the surface exposed to viruses.” For this, a study was done on the surface like a sample of dried mucus of corona virus patients, in which they were found free from the virus after one month.
Experiments conducted at 20, 30 and 40 ° C showed that the virus remains alive for a long time at cold temperatures. The virus remains alive longer on paper notes than smooth surfaces and plastic banknotes compared to uneven surfaces. All these experiments were done in the dark to remove the effect of ultraviolet light, as research has shown that direct sunlight can kill the virus.
Researchers said that proteins and fats found in body fluids can also increase the virus’s timelines in the body. This study can help in understanding the compatibility of viruses and meat packing facilities such as cold environments. However, Australia has better control of the corona virus than other countries.
Several studies have already been done on the relation of temperature and corona virus. At the same time, many experts say that cases of corona virus may come more than before in the cold season.
Dr. Randeep Guleria, director of AIIMS, has issued another warning saying that even a slight increase in pollution can increase the cases of corona. Doctor Guleria said that people need to be very careful during the winter months. He said, “Data from China and Italy show that in areas where PM2.5 levels have increased slightly, corona cases have seen at least 8-9% increase.”
Doctor Guleria said, ‘We have a habit of staying at home during the winter season. Due to more people living in the house, the infection can spread easily from one to the other. Respiratory virus also spreads easily in winter. Therefore, an increase can be seen in such cases, but it can be reduced by 30 to 40 per cent, taking care of mask, physical distance and hand hygiene.
