There have been some stories shared on social media of people being carefully approached by strangers who are in the high-risk categories for COVID-19 (older adults and people with heart disease, diabetes or lung disease) and asked for help with shopping or other resources, because the strangers are afraid to expose themselves by going into crowded stores themselves. Sometimes they are being given cash and a shopping list, which exposes these high-risk people to both theft and then not having supplies. If you have neighbors whom you know are in a high risk group, it is a good idea to contact them (ideally via a remote method that doesn’t expose them to anything you may be carrying) and ask if you can assist them with any preparations. You could also print them an OK/HELP sign so that they can notify neighbors if they need assistance, and the people for whom they have phone numbers aren’t able to respond to help.
Be mindful that you still need to practice good hygiene to prevent infection in either direction when passing off goods or payment.
