> Well, we know that COVID-19 can survive up to 24 hours on cardboard

Do you have a source for that? Nicholas Christakis (John Hopkins MD, infectious disease specialist) said on most surfaces, SARS-cov2 (the virus, COVID-19 is the disease) can survive an hour. He did mention it depends on the environment (it would only survive a few minutes on copper surfaces for example), so is cardboard able to hold the virus along longer? Is there data on this?

I think we just don't know yet. The WHO has this to say:

"It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).

If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose."

And the actual paper: https://www.medrxiv.org/content/10.1101/2020.03.09.20033217v...

Tangential, but the only Nicholas Christakis I know of is a sociologist[0]. Is there another one?
