Bedsheets, clothes and pillowcases can be disinfected first and returned to the patient or treated as medical trash, the statement said. Unopened food in the refrigerator may be disinfected and retained, while products that have been opened must be treated as medical trash. But scientists said that such disinfection was unnecessary for Sars-CoV-2, and served little purpose other than giving a false assurance of security. Instead, improved ventilation, as simple as opening windows, would greatly cut the risk of transmission in homes.
Health agencies and studies show Sars-CoV-2 is transmitted mostly by droplets with a diameter of 5 microns or above that can travel up to 1.8 metres and usually fall to the ground, or by smaller aerosol particles that can get caught in air flows and move throughout a space, infecting people at further distances.
However, the study did not reveal how much virus was put in the lab study, a factor that greatly influences the chance of survival. It was completed under highly controlled laboratory conditions, an environment much easier for viruses to survive in. In fact, a study by the University of Michigan found out exactly how much the risk from surface contamination of Covid-19 was lower than aerosol transmission: 1,000 times.
“Vaccination is the most powerful approach to protect the public from Covid-19, and wearing masks and regular personal hygiene such as hand washing are essential to reduce transmission.”
