Apparently with lockdown easing there has been an increase in other viruses so just thought I'd let everyone know about this.
Hand sanitizing gel works well for Covid because of the high alcohol content however non-enveloped viruses, including most sickness bugs are not destroyed by hand gel.
90% of stomach bugs are caused by different variants of Norovirus (there are loads) and a lot of cases of sickness that people think are food poisoning are actually Norovirus caught from the person preparing the food (obviously there are also bacterial food poisoning cases but these are less common).
If there is a stomach virus circulating in your area make sure to wash your hands very regularly (particularly when getting in from outside) and if you want to use a hand sanitizer buy an antiviral hand sanitizer containing 'Benzalkonium chloride' rather than an antibacterial gel, which is more likely to work.
