Answer:
Top surfaces touched (in a household): doorknobs, household appliances, electronic devices, countertops, tables, chairs, etc.
Explanation:
The top surfaces and items touched were doorknobs, household appliances (fridges, microwaves, sinks, etc), light switches, and countertops. Something that surprised me the most that I touched were the household appliances. I didn't realize how many times I touched the refrigerator and microwave. This observation taught me that microorganisms can spread easily. Just because we aren't around people who sneeze/cough doesn't mean we completely avoid the bacteria. If someone sneezes into their hands and then touches a door knob, everyone who touches it will contract the bacteria. Yes, I find this helpful in understanding the importance of working to break the chain of infection. You should be washing your hands constantly to kill off any bacteria you might've touched in your house. If you're in public and you don't have direct access to a sink, use hand sanitizer and wash your hands as soon as you get home.
Hope this helps!
