A new study published in The Lancet by the University of Hong Kong stated that the researchers analyzed the stability of the new coronavirus in different environments.
The study said, "On day 7, the outer layer of the surgical mask may still contain detectable infectious viruses." This detail alone should remind you that after each use, be sure to discard disposable masks, Wash the home-made reusable masks.
In addition, it is important to avoid touching the mask when using the mask and avoid touching your face during the use of the mask. The following are other findings from the study:
The virus is very stable at 4 ยฐ C/39.2 ยฐ F, but it is sensitive to high temperatures.
The virus is inactivated in only 5 minutes at 70 ยฐ C/158 ยฐ F.
Printing and paper: The virus died after 3 hours (22 ยฐ C/71.6 ยฐ F and 65% humidity).
Wood and cloth: The virus died after 2 days (22 ยฐ C/71.6 ยฐ F and 65% humidity).
Glass and banknotes: The virus died 4 days later (22 ยฐ C/71.6 ยฐ F and 65% humidity).
Stainless steel and plastic: The virus died after 7 days (22 ยฐ C/71.6 ยฐ F and 65% humidity).
The study found that the virus is very stable in a large pH range (3-10) but will die after disinfection.
In other words, it is necessary to keep common surfaces clean and wash clothes worn out and maintain proper hygiene. In addition, after handling items brought in from the outside, keep hands washed with soap for at least 20 seconds.
Conversely, exposure to high temperatures will kill viruses, which is a critical detail for foods. Foods that are heated will not show signs of viruses.
