Just Wash Your Hands! Infection Prevention 101

wash hands

The World Health Organization (WHO) is currently working with countries to help prepare them for the possible arrival of the new coronavirus (SARS-CoV-2) and has dispatched more than 12,000 kg worth of personal protective equipment to help. Meanwhile, Chinese banks have been ordered to disinfect cash, people are putting masks on their pets, and some have taken it one step further and covered their pets in plastic bags before venturing out.

In the midst of an epidemic it can be hard to know what you should be doing to protect yourself. However, it’s important to remember that although the names of the infectious diseases might change, the basic principles you should be following to prevent their spread have not.

What should you be doing?

1. Wash your hands (hand hygiene)

WHO and many experts around the world highlight that washing your hands frequently is one of the best ways to stop the spread of infectious respiratory diseases. The U.S Centers for Disease Control and Prevention (CDC) recommends good old-fashioned soap and water, but if that’s not available then use an alcohol-based hand sanitizer.

Washing your hands isn’t a complicated process, but you may not be doing it properly. The CDC recommends that you should:

  • Wet your hands under running water then apply soap. The temperature of the water isn’t really important and it’s ok to turn off the tap to save water.

  • Lather your hands. Make sure that you include the backs of the hands, in between your fingers and under your nails.

  • Scrub for about 20 seconds.

  • Rinse hands well under clean running water.

  • Dry your hands.

2. Avoid touching your mouth and nose - you may have germs on your hands.

3. Avoid crowded places, especially if people are coughing and sneezing.

4. Practice cough etiquette. If someone in your household does get sick, then remind them to practice good cough etiquette. They should cough into a tissue and dispose of it, or use their elbow if they don’t have a tissue.

5. Wear a mask if you’re sick to help prevent the disease from spreading to others. For those who aren’t sick, there’s no evidence that a mask is going to provide you with protection when you’re out and about.

If you are in a situation where you’re required to wear a mask then the following points are important to remember:

  • Ensure the mask fits securely over the mouth and nose and that gaps are minimized.

  • Do not touch the mask while you are wearing it.

  • When removing the mask untie it from the back. Do not touch the front of the mask.

  • Wash your hands after removing a mask or if you inadvertently touch it.

  • Replace the mask if it becomes damp.

  • Do not reuse single-use masks and dispose of them as soon as you have removed it.

More to worry about than just the new coronavirus

If you’re thinking that your chances of catching the new coronavirus are minuscule and you’ll just skip all that hand washing, it may be time to think again. In the US, for example, Dr. Anthony Fauci (director of the National Institute of Allergy and Infectious Diseases) warned in February 2020 about a second wave of influenza (flu), which seems to be hitting children very hard. So far this flu season, a total of 92 children have died from the flu in the US. 14 of those deaths occurred between late December and early February.
