First and foremost methods are using droplet protection and cleaning whenever you touch something that is infected.
Besides washing your hands and making sure you and other people cover their mouth when sneezing or coughing you could also do these methods:
Make a Face Mask. These can be made out of handkerchiefs, high collars(if you aren't suppose to wear one, but you need to), disposable paper products that can be thrown away after you use them once. You could buy ones but these are home-made ones.
Make a barrier. This can be done by putting high boundaries up, like books, laying coats across the area and etc. Anything that will protect against droplet infection.
Prevention of Droplet-spread Illnesses:
Avoid close contact.
Germs are transmitted easily when you live in
close quarters, especially during winter months when we stay indoors.
If you have a droplet-spread illness, avoid getting close to
colleagues, friends, or family members. Tell them you're sick and that
you don't want them to catch the virus. This helps protect them from
getting sick, too.
And remember to hand wash and disinfect things that a lot of people touch before eating or use.
You should wash or disinfect your hands whenever you've touched
something that an infected person might recently have touched:
computer keyboards, telephone receivers, doorknobs, elevator buttons,
faucet handles, countertops, railings, and so on.
- Using your sleeve when touching objects also helps. Using Vitamin C and other vitamins that promote immune health are suppose to help, but never overdose and consult a doctor. Vaccines are a must and depending on a the place you work, the vaccine may be free.
Additional Info
Know your company policy, and remember to always review it. If a person is spreading disease and other illness they may not be suppose to go work and they could be sent home depending on the policy.
Remember hand-washing protects against many diseases while using sanitizers doesn't. Sanitizers are good if you can't get to a sink. Always wash hands if they are visibly soiled, sanitizer will only make mud.
Disinfecting sprays can be made with 1/4 cup bleach and 1 gallon of water.
