How long the coronavirus survives on different surfaces?
The main transmission way of COVID-19 is droplets that are released when an infected individual coughs or sneezes and gets inhaled by a healthy individual. However, one can also be infected by contacting a surface on which the droplets land and then touching your mouth, nose, or eyes.
You should not also forget that you transfer the virus to everywhere you touch after you touch an infected surface.
Survival period of the coronavirus on various surfaces
Experts say that the virus is especially present on smooth surfaces such as doorknobs and countertops.
Initial studies showed that the survival period of the virus differs according to the type of the surface it lands on. Live virus can survive on a surface up to 3 hours to 7 days.
Glass - 5 days.
Wood - 4 days.
Plastic and stainless steel - 3 days.
Cardboard - 24 hours.
Copper surfaces - 4 hours.
Since the amount of live virus decreases over time, when you touch an infected surface after several days, the infection risk is also lower.
Contagious Dose of the COVID-19
The main purpose of a virus is to invade a living host and reproduce. Therefore, when an infected individual coughs and viral droplets land on a surface, the virus does not reach its expected environment and starts to die. There is a huge difference between the amount of the virus at the initial contamination and several days later.
Can we get infected with the coronavirus through the cargo packages arriving at our homes?
During the pandemics and restrictions, most of us shopping via online channels. This brings the same question to our minds; can we get infected with the coronavirus through the package deliveries?
Experts state that on porous surfaces such as paper and cardboard the survival period of the virus is much shorter.
As the number of conducted studies increases, it will be possible to access more accurate results, but as of now it is important to know that transmission from live sources is more worrisome. Therefore, we should continue taking precautions by keeping our social distance and paying attention to our personal hygiene. As an additional precaution, it would be beneficial to have the delivered packages wait for a couple of hours.
