First, about virus survival on surfaces in general:
Germany’s (kind of celebrity) virologist Christian Drosten’s (Berliner Charité hospital) opinion on the study about survival rates of Sars-CoV-2 on surfaces and the possibility of smear infection:
He hypothesizes that for the experiment, dass für den Versuch Viruses in a larger drop were put on the surface, and even though in this way you can verify infectiosity even after hours, probably only very few viruses survived. On fingers, the amount of viruses decreases further and gets into contact with the acidic milieu of the skin, and it is unclear whether anything remains; similarly simple experiments cannot simulate that. The German federal institute for risk assessment states that it currently does not know of Sars-CoV-2 infections via touching surfaces.
Note that I neither checked the statements cited, nor the sources; this is simply a translation and summary of a paragraph from the article. Starting from this, the article writes about disposable gloves.
The article states that gloves are of course considerable but that you of course should not touch your face with the gloves, and that it should also be considered that Sars-CoV-2 viruses seem to survive longer on plastics etc than on skin, that also bacteria thrive on gloves more than on hands and gloves distribute them more than hands do. Moreover, if you wear them for a longer time, the skin sweats and swells, which opens an entry to the body for viruses and bacteria. Finally, taking the gloves off without touching them is not as easy as you might think, and disposing them should of course be done properly, some people just leave them in the shopping cart.
The article basically recommends to prefer washing your hands and not touching your face over using disposable gloves. It also kind of suggests that gloves can be the opposite of face masks in one sense: Simple face masks do protect other people, while gloves may even make matters for other people worse.
