WHO researchers claim that the virus on paper products will die within 3 hours.
American researchers say that after 24 hours, the infectious new coronavirus will not be detected on the carton, which means that the risk of receiving express delivery is relatively low. The virus on paper prints, including newspapers, will die within 3 hours.
The World Health Organization today disclosed that patients with new coronary pneumonia are unlikely to contaminate goods, including packages transported by express companies. “The possibility of patients with new coronary pneumonia contaminating goods is very low, even if the package may be exposed to multiple environments, people will be infected from the package. The risk of the new coronavirus is very low."
An early study by the University of Hong Kong researcher Alex Chin and his colleagues found that the new coronavirus can remain stable for a long time at a temperature of 4°C. Without disinfection treatment, the virus decision is still quite high within 7 days at room temperature, but it will be eliminated after 14 days.
When the temperature rises to 37°C, the viral load will gradually decrease within 24 hours, and then it will not be detected. When the temperature rises to 56°C, the virus is no longer infectious after 30 minutes; when the temperature rises to 70°C, the virus loses its infectivity in just 5 minutes.
After 3 hours, the virus on the surface of the paper prints and paper towels is no longer infectious.
Earlier today, virologist George Lomonossoff told the BBC that the printing and production process means that newspapers are "substantially sterile." Therefore, people are infected with the new coronavirus due to exposure to newspapers. The risk of the virus is quite low.
