Let's assume you share this laptop with coworkers or some friends are coming over, or there's some other reason why people who might not have been exposed while you were sick will be exposed to virus particles protected by little blobs of snot on your laptop.
Take a cotton ball, soak it in isopropyl rubbing alcohol 70% concentration (commonly available at drugstore), squeeze some of the alcohol out so you aren't just dribbling it all over, and then rub down the keyboard, mousepad, screen, case etc with the cotton ball.
let it dry for a minute or two. Repeat.
Wipe off the excess with a dry cotton ball.
You're good to go. Do the same to your phone and any other gadget you might share with a friend or coworker.
It also does a good job of getting grime off your keyboard.
